Bhagavad-gita As It Is Lectures

Lecture on BG 2.10 -- London, August 16, 1973:

And because he is devotee, he is perfectly playing in such a way that Kṛṣṇa is giving instruction. So perfect teacher and the perfect disciple, Arjuna. We have to learn from their de... Our position... Arjuna is representing just like ordinary man like us, and Kṛṣṇa is Hṛṣīkeśa, giving His advice, perfect advice. If we take, if we read Bhagavad-gītā in the spirit of understanding like Arjuna, the perfect disciple, and if we accept the advice and the instruction of Kṛṣṇa, the perfect teacher, then we should know that we have understood Bhagavad-gītā. By my mental speculation, by rascal interpretation, by showing one's scholarship, you cannot understand Bhagavad-gītā. That is not possible.

Lecture on BG 2.13 -- New York, March 11, 1966:

So our thinking power, mind, is one of the senses. Out of the ten, mind is considered to be the eleventh sense. There are five karmendriya and five sensory organs and working organs, ten, and the mind is the chief. So mind is also considered as one of the senses, the chief senses. You see? So because it is sense, it is imperfect. So by mental speculation we cannot have a into right conclusion, by mental speculation. Those are simply speculating on mind, they can make some progress to a certain extent, but they cannot reach the ultimate goal. It is not possible by mental speculation; neither it is possible by direct evidence. The only, only possible evidence is authority, authority. Just like yesterday also I gave you that example.

Lecture on BG 2.13 -- Pittsburgh, September 8, 1972:

Dehinaḥ, of the living soul, the body is changing. Similarly, after death, after so-called death... Because there is no death. After stoppage of the function of this gross body, the soul is transferred to another gross body. This statement we get from Bhagavad-gītā. And if we accept this statement, "This is fact," then our spiritual life immediately begins. Without this understanding, there is no question of spiritual understanding. Everything vague, simply mental speculation, "maybe," "perhaps." These theories are being forwarded by so-called scientists and philosophers. But we don't accept such things as "perhaps," "maybe." No. We accept what is fact. It is not a question of belief; it is a question of fact. So this is the fact.

Lecture on BG 2.18 -- London, August 24, 1973:

So we cannot estimate by direct perception, even in this material world, and what to speak of the spiritual world. Not (possible.) Panthās tu koṭi-śata-vatsara-sampragamyo vāyor athāpi manaso muni-puṅgavānām (Bs. 5.34). By mental, muni-puṅga means mental speculation. You can go on mental speculating, but if you do even for many hundreds and thousand of years, it is not possible to calculate. You have to accept this truth through the śāstra; otherwise, it is not possible. Therefore Kṛṣṇa said, nityasyoktāḥ śarīr-ukta. Ukta means it is said. Not that "I am presenting some dogma," although He can do so. He's Supreme Personality of Godhead. This is the method. Unless there is ukta, said by authorities, previous authorities, ācāryas, you cannot say anything. This is called paramparā. You try to understand with your intelligence, but you cannot make any addition or alteration. That is not possible. Therefore it is called nityasyoktāḥ. It is said, it is already settled. You cannot argue. Nityasyoktāḥ śarīriṇaḥ anāśino 'prameyasya, immeasurable.

Lecture on BG 2.19 -- London, August 25, 1973:

So this knowledge, Bhagavad-gītā knowledge, is so perfect for the human society. And Kṛṣṇa wants that this knowledge should be spread because everybody, sarva-yoniṣu kaunteya sambhavanti mūrtayaḥ... (BG 14.4). He's the seed-giving father. Father is naturally well-wisher that: "These rascals, they are suffering, prakṛti-sthāni. Manaḥ ṣaṣṭhānīndriyāṇi prakṛti-sthāni karṣati (BG 15.7). Simply by, guided by mental speculation, manaḥ, and assisted by the senses, they are struggling so hard. And if they come back to Me they can live so nicely, as My friend, as My lover, as My father, as My mother, Vṛndāvana. So claim again, call them." That... Therefore, Kṛṣṇa comes.

Lecture on BG 2.23 -- Hyderabad, November 27, 1972:

We are simply calculating: "He may be one inch greater than me. Or one foot greater than me." That is mental speculation. Therefore Kṛṣṇa says, manuṣyāṇāṁ sahasreṣu kaścid yatati siddhaye: (BG 7.3) "Out of many millions of men, one may try to make his life successful, understanding the Absolute Truth." And yatatām api siddhānāṁ kaścin māṁ vetti tattvataḥ (BG 7.3).

So we cannot understand God by our mental speculation. Neither we can understand what is the measurement of the soul. That is not possible. Therefore we have to take information from the highest authority, Kṛṣṇa, what is the nature of God, what is the nature of Absolute Truth, what is the nature of the soul. We have to hear. We have to hear. Therefore the Vedic literature is called śruti. You cannot make experiment. That is not possible. But unfortunately, there is a section of people who think that they can make experiment, they can know the Absolute by mental speculation.

Lecture on BG 2.26 -- Hyderabad, November 30, 1972:

He must, one must become a Vaiṣṇava. Otherwise his so-called ideas and interpretation has no value. Has no value. Just like in your country, South India, Dr. Radhakrishnan, he has done so many works. But to tell you frankly, it is useless labor. Because he has said in one of his writings that Bhagavad-gītā is mental speculation. He is surpassing all the ācāryas who came, who appeared in South India. Rāmānujācārya appeared in South India, Madhvācārya appeared in South India. Nimbārka appeared in South India. Viṣṇu Svāmī appeared in South India. Śaṅkarācārya appeared in South India. South India is so blessed. And he also appeared in South India. He's decrying all the ācāryas. Just see the position. He says, "Bhagavad-gītā is a mental speculation." And he has interpreted in a different way.

Lecture on BG 2.46-62 -- Los Angeles, December 16, 1968:

Tamāla Kṛṣṇa: Purport: "The word muni means one who can agitate his mind in various ways for mental speculation without coming to a factual conclusion."

Prabhupāda: Mental speculators are called muni. There are so many munis. Go on.

Tamāla Kṛṣṇa: "It is said that every muni has a different angle of vision, and unless one muni is different in view from another, he cannot be called a muni in the strict sense of the term. But a sthita-dhīr muni, the kind mentioned herein by the Lord is different from an ordinary muni. The sthita-dhīr muni is always in Kṛṣṇa consciousness for he has finished all his business with creative speculation. He is called praśānta-niḥśeṣa-mano-rathāntara, or one who has surpassed the stage of mental speculation and has come to the conclusion that Lord Sir Kṛṣṇa, Vāsudeva, is everything. He is called a muni fixed in mind. Such a fully Kṛṣṇa conscious person is not at all disturbed by the onslaughts of the threefold miseries, those due to nature, to other beings, and to the frailties of one's own body. Such a muni accepts all misery as the mercy of the Lord, thinking himself only worthy of more trouble due to his past misdeeds, and sees that his miseries, by the grace of the Lord, are minimized to the lowest. Similarly, when he is happy, he gives credit to the Lord, thinking himself unworthy of that happiness. He realizes that it is due only to the Lord's grace that he is in such a comfortable condition and thus able to render better service to the Lord. And for the service of the Lord..."

Prabhupāda: You mark this. When there is miseries, a Kṛṣṇa conscious person takes the responsibility himself, and when there is happiness, it is due to Kṛṣṇa. But the materialistic person is just the opposite. When he is in miseries, he'll say, "Oh, God has put me into such miseries." And when he's happiness, his friend says, "Oh, you are now well-to-do." "Yes, you do not know how much I have worked hard." When he's happiness, he takes the credit for himself, and when he's in distress, he gives the discredit to Kṛṣṇa. "Oh, Kṛṣṇa has put me into such miserable..." But a Kṛṣṇa conscious person, when he's in distress, he'll say, "Yes, due to my misdeeds I should have suffered a hundred times more than this distress, but Kṛṣṇa is so kind, He has given me little. That's all." And when he's happiness, "Oh, it is all given by Kṛṣṇa. Therefore all the opulence should be utilized for Kṛṣṇa's service." This is the difference. He's asking, Arjuna is asking, what are the symptoms of Kṛṣṇa conscious person. Sthita-prajña. Sthita-prajña means steadfast in intelligence. So these are the difference. I have read one speech, Chicago speech by late Vivekananda Swami. He's talking to the audience that "You work so hard, why you give credit to God?" You see? If you find his Chicago speech, you'll see.

Lecture on BG 2.51-55 -- New York, April 12, 1966:

So this is our position. This is called conditioned stage of life. There is no freedom. The so-called freedom... We declare that "I belong to the free nation. I am free." These are all simply mental speculation. There is no freedom. So long I am bound up by the conditions of nature, there is no freedom. Now, here is a chance... Lord Kṛṣṇa says that karma-jaṁ buddhi-yuktā. Now, here is an opportunity for you. In human form of your life, you have got sufficient intelligence, and the Lord Himself is before you to enlighten your intelligence more and more. Here is the book. This book, what is spoken by Lord Kṛṣṇa, and Kṛṣṇa is not different. Because Kṛṣṇa, or the Lord, is on the absolute plane. Don't think that Kṛṣṇa is absent. Kṛṣṇa is present here.

Lecture on BG 2.55-58 -- New York, April 15, 1966:

So the Lord says that kāmān sarvān pārtha mano-gatān. The mental speculation, so long we are on the platform of mental speculation, we should understand that we are on the material plane, because mind is material. Mind is not spiritual. So mano-gatān. The special word is used here, mano-gatān. Whatever we create in our mind, that is material, all creations. Mind is the leader of the senses. So the activities of the mind—thinking, feeling and willing—are expressed through our senses. And these sensual activities are known as our living condition. Therefore the Lord says, "When one shall be free from mental speculation, then he's to be understood that he is in the perfect stage of spiritual consciousness." Mental speculation. So by mental speculation we cannot understand what is our position. Generally, people, they indulge in mental speculation. Different philosophy of the world, they are established on the principle of mental speculation, especially in Europe, Aristotle, Schopenhauer, Kant.

Lecture on BG 2.55-58 -- New York, April 15, 1966:

Mental platform cannot give us the actual freedom or the happiness. Therefore Lord says, "One should give up all mental speculation and should be satisfied in the understanding that 'I am consciousness, and there is Supreme Consciousness, and I am subordinate to the Supreme Consciousness. Therefore let me dovetail my consciousness with the Supreme Consciousness.' " Last day also, we discussed on this point. And the point is very clearly manifested in the teachings of the Bhagavad-gītā, that Arjuna mentally speculated in the beginning that "Whether I should take up this fighting or not?" But at the ultimate issue he gave up his mental speculation and agreed with the Lord that "Yes, I shall fight."

Now, this "Yes, I shall fight", this "I", and the former "I"—"I shall not fight"—so there is vast difference. The former "I" is the representative of mental speculation, when Arjuna decided that "I shall not fight. They are my relatives, they are my brothers; I cannot fight with them for the matter of kingdom. Rather, I shall forego; I shall become a beggar. I shall... I don't want this kingdom." He argued like that. But after reading Bhagavad-gītā, he said that "My illusion is now removed." Naṣṭo mohaḥ smṛtir labdhā: "My illusion is now removed, and I have got my consciousness by Your mercy. By Your mercy."

Lecture on BG 2.55-58 -- New York, April 15, 1966:

Now, we should always understand that we are meant for serving the supreme whole. That is our position. So this, this position, maintaining, and mental speculation, that "I am the Lord," by argument, by jugglery of words, the Lord says, Kṛṣṇa says, you should give up all these things. Mano-gatān. Mano-gatān. There is another instruction in the Śrīmad-Bhāgavatam that harāv abhaktasya kuto mahad-guṇā manorathenāsati dhāvato bahiḥ (SB 5.18.12). Yasyāsti bhaktir bhagavaty akiñcanā sarvair guṇais tatra samāsate surāḥ: "If one is situated in pure devotional service of the Lord, then, whatever he may be, all the good qualities of the Lord will develop in him, will develop, all the good qualities." And harāv abhaktasya kuto mahad-guṇāḥ: "And one who is not a devotee of the Lord, however academically he may be educated, his qualification has no value." Why? Now, manorathena: "Because he's on the platform of mental speculation, and due to his mental speculation, he is sure to be influenced by this material nature." He's sure to. So if we want to be free from the influence of the material nature, then our habit of mental speculation may be given up. That is the instruction in this verse.

Lecture on BG 2.58-59 -- New York, April 27, 1966:

Just like in the previous śloka it has been explained, prajahāti yadā kāmān sarvān pārtha mano-gatān. We manufacture plans by our mental concoction. That should be given up. Yadā prajahāti kāmān sarvān. All kinds of mental concoction, mental speculation, should be given up. That is the science. That is the beginning of our spiritual life, that "I shall not use my mind for my activities. I shall wait for the direction from the higher authority, supreme consciousness. Then I shall act."

Lecture on BG 2.58-59 -- New York, April 27, 1966:

Similarly, if we do, if we act according to our mental speculation or mental whims, then we are bound up by the reaction. And if we practice ourself to be active under the direction of the Supreme, then we are free. This is the art. This is the whole art of spiritual life.

So we have to practice. We have to practice it in our everything. Because for so long we are in this material body, we have got so many material demands. We cannot stop the activities of the body. That is not possible. By force, if I stop all the activities of my body, that is not possible. That is not possible. The bodily activities will go on, but the bodily activities will be so performed that I'll not be bound up by the reaction. And that is called devotional service.

Lecture on BG 3.1-5 -- Los Angeles, December 20, 1968:

Tamāla Kṛṣṇa: "In this verse the Lord explains the same more clearly. Sāṅkhya-yoga or the analytical study of the nature of spirit and matter is the subject for persons who are inclined to speculate and understand things by experimental knowledge and philosophy. The other class of men work in Kṛṣṇa consciousness, as is explained in verse sixty-one of the same Second Chapter. The Lord has explained also in verse thirty-nine that by working under the principles of buddhi-yoga or Kṛṣṇa consciousness one can be relieved from the bondage of action and furthermore there is no flaw in the process. The same principle is more clearly explained in verse sixty-one, that this buddhi-yoga is to depend entirely on the Supreme or more specifically, on Kṛṣṇa, and in this way all the senses can be brought under control very easily. Therefore both the yogas are interdependent, as religion and philosophy. Religion without philosophy is sentiment or sometimes fanaticism, while philosophy without religion is mental speculation. The ultimate goal is Kṛṣṇa."

Prabhupāda: There are certain class of men who are simply philosophizing and there are certain class of men who are simply blindly following religious ritualistic process. So Bhagavad-gītā is combination of both. That is scientific. You should be religious, but should understand everything philosophically. Otherwise one becomes fanatic, religious fanatic. In the Caitanya-caritāmṛta it is clearly said that caitanyera dayāra kathā karaha vicāra. You people, you try to understand the gifts of Caitanya Mahāprabhu by your philosophical understanding. Not blindly, philosophically. And vicāra karile citte pāibe camatkāra. If you are actually a wise man, then you'll find it is sublime. And if you simply stick to your own religious ritualistic principles, don't try to understand the philosophy of everything, then you become a fanatic. So we should not become religious fanatics, nor dry mental speculators. Both these classes of men are dangerous. They cannot make any advance. The combination. You should be religious, but try to understand each and every line philosophically.

Lecture on BG 3.31-43 -- Los Angeles, January 1, 1969:
Generally, those who are under the bodily concept of life, they are struggling day and night. Why? Now, to have overlordship of this material nature. This is material activities. And those who are on the mental platform, they are trying to philosophize, mental speculation. Those who are still intelligent, they are taking to this yoga practice by intelligently trying to controlling the senses. But as soon as you come to the spiritual platform, automatically these things are done because all your senses, mind, and intelligence are occupied by Kṛṣṇa consciousness. go on.
Lecture on BG 4.1 -- Montreal, August 24, 1968:

If you want to know God by your challenge, that "I can understand, I can see; therefore I shall see God, then I'll...," you'll never see Him. You'll never see. God is not under your challenge. Therefore the qualification of understanding God is surrender. Sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja (BG 18.66). And the process of understanding God is from God, not from others. He's so great, how can you understand by your mental speculation?

So here in the Bhagavad-gītā, Lord Śrī Kṛṣṇa, the Supreme Personality of Godhead, is revealing Himself by His causeless mercy.

Lecture on BG 4.1 -- Montreal, August 24, 1968:

So similarly, if one is not bhakta, if one is not Kṛṣṇa's devotee, that rascal cannot understand Bhagavad-gītā. Plainly. Plainly it is stated here. First of all, try to become the devotee of Kṛṣṇa. Then try to understand what is Bhagavad-gītā. Not by your scholarship or by your speculation. Then you'll never understand Bhagavad-gītā. If you have to understand Bhagavad-gītā, then you have to understand by the process as stated in the Bhagavad-gītā, not by your own mental speculation. This is the process of understanding.

Lecture on BG 4.1 -- Delhi, November 10, 1971:

So, you can imagine great, the great, this universe, the sky, millions and millions of miles spreading. The scientists say that to go the topmost planet of this universe, it will take forty thousands of years in the light year speed. But you can see there are so many planets. Just like you are trying to go to the moon planet, similarly there are other planets, but you cannot go. It is so big, beyond your reach. This is one universe, but there are innumerable universes. As you see that within this planet there are innu..., within this universe there numberless planets, you cannot count even. So similarly, there are innumerable universes, and all these universes together is within God. So the conception of God cannot be attained by our mental speculation. It is not possible. If you speculate what is God, you cannot understand.

Lecture on BG 4.4 -- Bombay, March 24, 1974:

Although he has got the frailty.... Because the living entity is the minute particle of God, mamaivāṁśo jīva-bhūtaḥ (BG 15.7), therefore his intelligence, his power, is also very minute. But God's power is unlimited. By unlimited power Kṛṣṇa knows the past, future, and present, everything perfectly. But our limited knowledge, we cannot know that. Therefore we have to receive knowledge from Kṛṣṇa. This is our position. Tad-vijñānārthaṁ sa gurum evābhigacchet, samit-pāṇiḥ śrotriyaṁ brahma-niṣṭham (MU 1.2.12).

So we have to approach either Kṛṣṇa or Kṛṣṇa's representative. Then we can understand Kṛṣṇa. Otherwise, simply by mental speculation, by so-called erudite scholarship, nobody can know.

Lecture on BG 4.9 -- Bombay, March 29, 1974:

Just see how much unfortunate we are. As you serve Kṛṣṇa, you understand Kṛṣṇa. You cannot understand Kṛṣṇa otherwise, unless you render service. Sevonmukhe hi jihvādau svayam eva sphuraty adaḥ. Ataḥ śrī-kṛṣṇa-nāmādi na bhaved grāhyam indriyaiḥ (CC Madhya 17.136). If you simply exact your senses, your nice brain, "Kṛṣṇa is like this, Kṛṣṇa is like that," but if you are not a devotee, Kṛṣṇa will not reveal Himself. Nāhaṁ prakāśaḥ sarvasya yoga-māyā-samāvṛtaḥ (BG 7.25). The rascal's mental speculation will not help him to understand Kṛṣṇa, what He is. That is not possible. His all activities are divyam, transcendental. We cannot understand with our material blunt senses. That is not possible. Therefore, the śāstra says, ataḥ śrī-kṛṣṇa-nāmādi na bhaved grāhyam indriyaiḥ. These blunt senses, you cannot understand Kṛṣṇa. Or Kṛṣṇa means His name, His form, His quality, His activities, His pastimes, so many things.

Lecture on BG 4.11 -- Geneva, June 1, 1974:

In another place Kṛṣṇa says, bhaktyā mām abhijānāti yāvān yaś cāsmi tattvataḥ (BG 18.55). Kṛṣṇa never says that "By mental speculation or yogic mystic practice, one can understand the Supreme Lord." Never says that. It is clearly said that bhaktyā mām abhijānāti yāvān yaś cāsmi tattvataḥ (BG 18.55). Tattvataḥ means in truth. To understand Kṛṣṇa in truth, that requires bhakti or bhakti-yoga, not the jñāna-yoga or karma-yoga, haṭha-yoga or any other yoga system. By other yoga system like jñāna-yoga or karma-yoga, haṭha-yoga, you can understand Kṛṣṇa partially. As I have explained, that somebody is seeing the mountain as hazy cloud and somebody is seeing as greenish something, and somebody is seeing actually the mountain with all varieties, so without bhakti-yoga realization of the Absolute Truth, it is partial.

Lecture on BG 4.12 -- Bombay, April 1, 1974:

Kṛṣṇa's another name is Ajita: He is never conquered. But any person who hears about Kṛṣṇa, jñāne prayāsam udapāsya namanta eva san-mukharitāṁ bhavadīya-vārtām, simply mental speculation, giving up this bad habit, jñāne prayāsam udapāsya, leaving aside, namanta eva, very humbly and meekly, if one hears from the realized soul about Kṛṣṇa, then in any position, sthāne sthitāḥ, because he is hearing from the realized soul, then one day it will be possible to conquer the unconquerable. Prāyaśo 'jita jito 'py asi tais tri-lokyām.

Lecture on BG 4.14 -- Vrndavana, August 6, 1974:

That is stated here. Iti māṁ yo 'bhijānāti. In this way, if one understands Kṛṣṇa, karmabhir na sa badhyate, he does not become entangled with the karma. In another place it is also confirmed: janma karma me divyaṁ yo jānāti tattvataḥ. If one understands Kṛṣṇa's activities, Kṛṣṇa's birth and Kṛṣṇa's form, Kṛṣṇa's attributes, if one can understand tattvataḥ, in truth, not by mental speculation. In truth, as it is, then what happens? Tyaktvā dehaṁ punar janma naiti (BG 4.9). He does not get any more material body after leaving this body.

So try to understand Kṛṣṇa on this principle, as Kṛṣṇa says. Don't imagine, don't speculate. Then your life will be perfect.

Lecture on BG 4.26 -- Bombay, April 15, 1974:

And those who are little advance, they are in the enjoyment of the mind, mental speculation, philosophy, or theosophy. So many "sophies" are there. Somebody putting some theories, this theory, that theory, that theory. Mental speculation. They derives poetry, writing poetry, nice poetry. They are not on the gross platform of sense gratification but on the subtle platform of sense... Mind is also sense. Mind is also sense.

Lecture on BG 4.34-38 -- New York, August 17, 1966:

Therefore here it is stated in the Bhagavad-gītā that tad viddhi praṇipātena: (BG 4.34) "If you are at all serious to understand that transcendental knowledge, then you must approach to a person who has experience of the Absolute Truth." Otherwise, it is not possible. If you think that "I shall realize by mental speculation the Absolute Truth, it is not possible." Because you are sub... I mean, you are fructified with only imperfections. Your senses cannot approach. Therefore Brahman is said, avan mānasa gocara. Avan mānasa gocara: "It is beyond, beyond the mental speculation." And there is another name of the Supreme Lord, Adhokṣaja.

Lecture on BG 4.34-39 -- Los Angeles, January 12, 1969:

Madhudviṣa: "The path of religion is directly enunciated by the Lord. Therefore mental speculation or dry argument cannot help one progress in spiritual life. One has to approach a bona fide spiritual master to receive the knowledge. Such a teacher should be accepted in full surrender, and one should serve the spiritual master like a menial servant, without false prestige."

Prabhupāda: Yes. The brahmacārī means... These are indication. When a person... When a boy becomes brahmacārī, even if he is the son of very rich man, he should live with the spiritual master as a menial servant. These are the injunction. That, Kṛṣṇa. Kṛṣṇa, He is the Supreme Personality of Godhead. Apart from his Godheadship, He was a very rich man's son. Really He was a very great king's son, Vasudeva, but He was given under the protection of King Nanda, Nanda Mahārāja, His foster father. He was also very rich man, very... He was king... (break) ...training of brahmacārī. So how he can see? When... Even if he is grown up, he cannot see any other woman in other way. He thinks of "Every woman is mother." This is the training. Of course, that training is not possible at the present moment. The days have changed. But this Kṛṣṇa consciousness movement is so nice that even brahmacārī begins immediately, he is trained up. He is trained up very nicely.

Lecture on BG 5.14-22 -- New York, August 28, 1966:

Just like in the Caitanya-caritāmṛta the author says that in this material world, which is illusion, our division that "This is good; this is bad," these are all mental speculation only. In the higher stage they see that in the material bondage nobody is in goodness. Everyone is in trouble. So this material calculation that "This is good, this is bad, and this is happy, and this is miserable," in the transcendental position they think that they are all equal. Ihaiva tair jitaḥ sargo yeṣāṁ sāmye sthitaṁ manaḥ (BG 5.19). Now, one who is situated in such transcendental position of mind, then, ihaiva tair jitaḥ sargaḥ, then in this very body he has conquered rebirth.

Lecture on BG 5.14-22 -- New York, August 28, 1966:

Just a person in transcendental position, he sees equally the intelligent man and the dog equal. Intelligent man and the dog equally. A brāhmaṇa, a dog, a cow, an elephant, and a dog-eater. So all these categories... There are different categories of life, but one who is situated in the transcendental position, they do not see any difference because in the material world this, I mean to say, this position is higher and this position is lower. They are all simply mental speculation. Actually, one who is not situated in the Kṛṣṇa consciousness, his higher and lower calculation—all so-called speculation. That's all.

Lecture on BG 5.26-29 -- Los Angeles, February 12, 1969:

This Fifth Chapter is a practical explanation of Kṛṣṇa consciousness, generally known as karma-yoga. The question of mental speculation as to how karma-yoga can give liberation is answered herewith. Working in Kṛṣṇa consciousness is to work with the complete knowledge of the Lord as the predominator. Such work is not different from transcendental knowledge. Direct Kṛṣṇa consciousness is bhakti-yoga and jñāna-yoga is a path leading to bhakti-yoga. Kṛṣṇa consciousness means to work in full knowledge of one's relationship with the Supreme Absolute and the perfection of this consciousness is full knowledge of Kṛṣṇa or the Supreme Personality of Godhead. A pure soul is the eternal servant of God as His fragmental part and parcel.

Lecture on BG 7.1 -- San Francisco, March 26, 1968:

So Kṛṣṇa consciousness is a great science. It is not a sentiment or mental speculation or bluff. It is based on scientific proposition, as described in the Bhagavad-gītā, as described in the Vedas, as described in the Saṁhitās, as accepted by the authorities like Lord Caitanya, Rāmānujācārya, Madhvācārya, Nārada, Asita, Vyāsa. There are so many authorities. So Kṛṣṇa consciousness is not an ordinary bluff-making or a money-making business. It is something reality. And if you take to it seriously, your life will be successful.

Lecture on BG 7.1 -- San Francisco, September 10, 1968:

So similarly, if with everything we have got some relationship, why not with God? There is. That is practical relationship, but we have forgotten. We have forgotten our relationship. And yoga means to connect, to reconnect that relationship again. That is called yoga. Yoga is not a mental speculation or for health's sake. Oh, for health's sake you may not go to the yoga system. If you simply adopt the practice of Sandoz exercise you can become very healthy, very strong. There is no need of... Yoga is different thing. Yoga means concentration of the mind towards God, God, Paramātmā, which we have forgotten now.

Lecture on BG 7.1 -- Ahmedabad, December 13, 1972:

Govinda is very, very difficult to understand by mental speculation, philosophical theses. Philosophical theses, speculation, without religion is simply waste of time. And religion without philosophical basis is sentiment. They must be combined together.

So Bhagavad-gītā is that, religion combined with philosophy. If you simply take philosophy, it is dry speculation. No juice. Carvita-carvaṇānām: "Chewing the chewed." There is no benefit. And if you take, simply take religion without basis of philosophy, then it is fanaticism. That's all. So both should be combined. Religion based on philosophy and logic, that is religion. So that combination is Bhagavad-gītā. So here in the Seventh Chapter, beginning, opening chapter, it is said, bhagavān uvāca. You are searching after God. Now here is God Himself speaking. So recognized God by all sages: Vyāsadeva, Nārada, Asita. And later on by Rāmānujācārya, by Śaṅkarācārya, by Madhvācārya, by Viṣṇu Svāmī, by Caitanya Mahāprabhu, and then our Guru Mahārāja. So our method is very simple: evaṁ paramparā-prāptam imaṁ rājarṣayo viduḥ (BG 4.2). So we accept this paramparā system. I may not know what is God, but because my predecessors, ācāryas, confirm it, the "Here is Bhagavān," we accept it. That's all. We save so much trouble by mental speculation. We accept the paramparā system. Therefore... And we get the result. So that is the way.

Lecture on BG 7.1 -- Calcutta, January 27, 1973:

If you want to know Kṛṣṇa or God by the speculative process, not only for one year, two years... Panthās tu koṭi-śata-vatsara-sampragamyo vāyor athāpi. Not mental speculation, but on the aeroplane running on the speed of vāyu, or air, or mind, the speed of mind, still, by traversing many crores of years, you cannot reach. Still it, it remains avicintya, inconceivable. But if you take to the process of this kṛṣṇa-yoga, or bhakti-yoga, then you can become aware of Kṛṣṇa very easily. Bhaktyā mām abhijānāti yāvān yaś cāsmi tattvataḥ (BG 18.55). To understand Kṛṣṇa superficially, that is not sufficient. That is also good, but you must have tattvataḥ, what is Kṛṣṇa actually.

Lecture on BG 7.1 -- Durban, October 9, 1975:

Even big, big men, big, big leaders, they commit so many mistakes. And so far illusion is concerned, everyone is illusioned because I am not this body, but everyone is thinking, "I am this body." This is called illusion. Dehātma-buddhi. "I am not this body. I am spirit soul." Ahaṁ brahmāsmi. But I am thinking, "I am Indian," "I am American," "I am South African," "I am black," "I am white," "I am fat," "I am thin." This is bodily. This is called illusion. And we invent our ideologies by mental speculation, without having perfect knowledge. We are accustomed to say, "I think." But "I think"? What I am? All my senses are imperfect. I commit mistake, I am illusioned, and when I say, "I think," what is the use of my thinking? This is cheating. This is cheating.

Lecture on BG 7.1-3 -- Ahmedabad, December 14, 1972:

So Kṛṣṇa is advising simply by increasing your attachment for Kṛṣṇa, we can be eligible to understand the whole knowledge, complete knowledge, without any doubt. By our mental speculation we acquire knowledge, but there are so many doubts. So many doubts. In the Ninth Chapter also, in the Bhagavad-gītā, it is said, pratyakṣa avagamaṁ dharmyam. Pratyakṣa. Kṛṣṇa consciousness knowledge is so perfect that pratyakṣa avagamam, you can directly perceive how far you are making progress. You don't require to take certificate from others, whether you are progressing or not. You'll understand, yourself. The example is given. Just like a hungry man is eating, so as he going on, eating, he's getting strength and his hunger is being satisfied. So he can understand himself. Nobody requires to certify, "Now you are satisfied," or "Now..." Similarly bhakti, Kṛṣṇa consciousness, is so perfect that pratyakṣa avagamam, one can understand directly. Bhaktiḥ pareśānubhavo viraktir anyatra syāt (SB 11.2.42). This is the test of bhakti-mārga.

Lecture on BG 7.1-3 -- Ahmedabad, December 14, 1972:

So for, by standard knowledge, by understanding Vedas, that is standard knowledge. Still, although they are siddhas, still they do not understand Kṛṣṇa. Just like karmīs, jñānīs, yogis, they have taken to standard knowledge. That's a fact. But still, they cannot understand Kṛṣṇa. The Māyāvādīs, the impersonalists, the speculators, they cannot understand. They are surprised, that "How Kṛṣṇa can be the Absolute Truth?" Even a, a great scholar, Dr. Radhakrishnan, he's also amazed. He says that "Bhagavad-gītā is mental speculation." And when Kṛṣṇa says on the Ninth Chapter... He writes commentary. Man-manā bhava mad-bhakto mad-yājī māṁ namaskuru (BG 18.65). He says that "It is not up to Kṛṣṇa, but the fact which is within Kṛṣṇa." So he does not know what is Kṛṣṇa, and still, he dares to write commentary on Bhagavad-gītā. This is the difficulty. Kṛṣṇa has no inside or outside. Kṛṣṇa is all spirit, all spirit.

Lecture on BG 7.1-3 -- Stockholm, September 10, 1973:

Because it is a science. Religion means a kind of faith. It is not faith. It is a science. Science must be based on logic and philosophy. Science means that. And religion means sometimes sentiments. So religion without philosophy is sentiment, and philosophy without religion is mental speculation. Both must be combined. Then it is perfect. You cannot have religion without philosophy. That is sentiment, fanaticism. And if you simply take philosophy without religion, without sense of God, this is mental speculation. So religion must be on the basis of science and logic. That is first-class religion.

Lecture on BG 7.1-3 -- Paris, June 13, 1974:

We are speaking from Bhagavad-gītā. I think most of you know this book, Bhagavad-gītā. The Bhagavad-gītā is sometimes translated in foreign languages: "The Song of God." In other words, God Himself speaking. So far we are concerned, we cannot understand God by mental speculation. Even in this material world, we cannot understand what is there in the planetary systems. So our knowledge is very, very limited. Besides that, we have got four deficiencies.

Lecture on BG 7.1-3 -- Paris, June 13, 1974:

There is one religion. One who knows God, he is religious. One who does not know God, that religion has no meaning. Religion means to understand the order of God. That is religion. But if you do not know what is God, and how you can hear His order? So religion without understanding God philosophically and logically is sentiment. And philosophy without understanding of God is mental speculation. So when philosophy and religious sentiments combine, that is called religion. Otherwise, it is not religion.

Lecture on BG 7.3 -- Bombay, March 29, 1971:

It is not easy to understand Kṛṣṇa. But Kṛṣṇa is so kind that He is coming personally and He is leaving behind Him this Bhagavad-gītā to understand Him. That is Kṛṣṇa's kindness. Otherwise, by so-called mental speculation, you cannot understand Kṛṣṇa. It is not possible. Ataḥ śrī-kṛṣṇa-nāmādi na bhaved grāhyam indriyaiḥ (CC Madhya 17.136). If a person is very expert in exercising his senses, mental speculator, it is not that he will understand Kṛṣṇa. Ataḥ śrī-kṛṣṇa-nāmādi. Nāmādi means His holy name, Hare Kṛṣṇa. Because name is the first. In our, this forgetful condition, our first business is to chant the holy name. Therefore nāmādi. To understand Kṛṣṇa we have to chant His holy name first, ādi. Then gradually, Kṛṣṇa's qualities, Kṛṣṇa's form, Kṛṣṇa's pastimes, Kṛṣṇa's entourage and everything will be revealed.

Lecture on BG 7.4-5 -- Bombay, March 30, 1971:

One who thinks that mental speculation is spiritual speculation, that is wrong. Here from Bhagavad-gītā we understand the mind is also subtle form of matter, and actually that is so. Because we get another body after death according to the mental situation at the time of death. The mind, intelligence, the subtle body... Just like at night our subtle body, mind, intelligence works, and we think that we have got a separate body and have gone somewhere else from our house, from our room. We forget this material body. Similarly, after death, my mind and intelligence carry me to another separate body according to my thinking at the time of death. So false ego. This false ego is that "I am something of material product." This is called false ego. Actually, though, ahaṁ brahmāsmi: "I am Brahman."

Lecture on BG 7.8-14 -- New York, October 2, 1966:

Oh, you cannot do it by mental speculation. You cannot get rid of this entanglement of three qualities. It is not possible. It is very strong. Don't you think how we are in the grip of the material nature? It is not possible. Daivī hy eṣā guṇamayī mama māyā. Guṇa. Guṇa means this quality, and another meaning of guṇa is rope. Just like we have seen rope, one rope, two rope, three ropes. When three ropes are, I mean to say, bound up, twisted in one, oh, that becomes very strong. Guṇa means rope also. So we are tied up hands and feet with that rope of these qualities, three. You see? It is very difficult to get out of it. Then? Hopelessness? No. No hopelessness. How can I get rid out of it? Mām eva ye prapadyante māyām etāṁ taranti te: (BG 7.14) "Anyone who surrenders unto Me, he is at once free." Anyone who becomes Kṛṣṇa conscious by this way or that way, he becomes free.

Lecture on BG 8.28-9.2 -- New York, November 21, 1966:

So here this very word is used, anasūyave. Arjuna is hearing from Lord Kṛṣṇa without any enviousness. He's accepting what does He say. This is the way of understanding. We cannot understand by our mental speculation what is God. We have to hear, and we have to accept. Otherwise there is no way to understand what is God. So God says that "Because you are not envious, therefore, I speak to you about the most confidential part of knowledge." Jñānaṁ vijñāna-sahitam. Vijñāna-sahitam means this knowledge is not theoretical, but it is scientific. Whatever knowledge we get from Bhagavad-gītā, we should not think that it is sentimentalism or fanaticism.

Lecture on BG 8.28-9.2 -- New York, November 21, 1966:

Now, this process of knowledge or this process of activity which we are trying to propagate as Kṛṣṇa consciousness... Knowledge means, the topmost knowledge means Kṛṣṇa consciousness according to Bhagavad-gītā. Because in the Bhagavad-gītā you'll find that a person who is learned, who is actually in knowledge, his symptoms will be that he has surrendered unto God. That is the symptom of knowledge. So long we go on speculating about God but do not surrender, that is not perfection of knowledge. Perfection of knowledge is bahūnāṁ janmanām ante: (BG 7.19) "After many, many births' mental speculation, philosophical speculation, when one understands what is actually God, God, then he surrenders there. He surrenders there." So long we do not surrender, we cannot understand God. So bahūnāṁ janmanām ante jñānavān māṁ prapadyate. The Lord says, "One who is actually in knowledge, that knowledge is achieved after many, many births, not all of a sudden."

Lecture on BG 9.3 -- Toronto, June 20, 1976:

"These living entities," Kṛṣṇa says, "They are My part and parcels. But foolish rascals, they're creating concoction, mental speculation, to become happy." Manaḥ ṣaṣṭhānīndriyāṇi. And according to their mentality they are getting a different type of body, indriyāṇi. Indriyāṇi, the... As I was explaining in one morning, the pig has got also tongue, that is indriya, sense, and I have got also tongue, but his tongue will like to eat stool. We won't like. Because the different body, the tongue is also tasteful in different way. So indriyāṇi. Manaḥ ṣaṣṭhānīndriyāṇi. First of all with subtle mind we create a different type of indriya. If we live like dogs and hogs, then that mentality will give me similar senses, the body of a dog and hog. And we change our taste according to dog and hog. Similarly, we can change our taste according to the body of demigods. But the subject matter of tasting or enjoyment is the same. Eating, sleeping, sex and defense. That will continue. But the quality of eating may be different. Not the quality, but the form may be different.

Lecture on BG 9.11-14 -- New York, November 27, 1966:

Govinda, the Supreme Lord, who is so vast that you cannot reach Him by your mental speculation... Panthās tu koṭi-śata-vatsara. Koṭi means ten million, and koṭi-śata-vatsara, similarly, millions and millions of years, with the speed of air and with the speed of mind, if you proceed to speculate, to understand the Supreme, oh, that is not possible. That is not possible. So many speculators at the present moment or in the past, speculating, speculating, speculating. They never reach the point, never reach the point. There is not a single instance that they have reached the point.

Lecture on BG 13.1-2 -- Miami, February 25, 1975:

So our Kṛṣṇa consciousness movement is teaching people to become submissive to the authority. That is the beginning of knowledge. Tad viddhi praṇipātena paripraśnena sevayā (BG 4.34). If you want to learn the transcendental subject matter which is beyond the scope of your thinking, feeling and willing... Mental speculation means thinking, feeling and willing, psychology. But subject matter which is beyond your thinking. So God or anything about God is beyond the limit of our thinking, speculation. Therefore, we have to learn it submissively. Tad viddhi praṇipātena, praṇipāta means submission. Prakṛṣṭa-rūpeṇa nipāta. Nipāta means submission. Tad viddhi praṇipātena paripraśnena. First of all find out somebody where you can fully surrender. Then you enquire about transcendental subject matter.

Lecture on BG 13.8-12 -- Bombay, September 30, 1973:

So Kṛṣṇa has explicitly explained that brahma-sūtra-padaiś caiva hetumadbhir. Hetumadbhir viniścitaṁ. The Brahma-sūtra is called therefore nyāya-prasthāna, with logic and reason, hetumadbhir, cause and effect, Everything. Because people like to understand on the basis of philosophy and reasoning everything. Yes, that is required.

Any understanding without philosophy, that is sentiment. And philosophy without religious conception is mental speculation. These two things are going on, not combined. All over the world there are many so-called religious systems, but there is no philosophy.

Lecture on BG 13.8-12 -- Bombay, October 2, 1973:

Adhyātmā-jñānam, to understand oneself as the spirit soul, that jñānam. Adhyātmā-jñānam, tattva-jnanārtha-darśanam. Philosophy should be utilized. Logic and philosophy should be utilized for self-realization, not for simply mental speculation.

We find nowadays, big, big philosophers write volumes of book, simply theorizing without any understanding of the spirit soul. Big, big philosopher. And Kṛṣṇa says that if one simply puts philosophical theories for some utopian ideas, "Now time is coming which will be like this, like that." No. Time is there already. You cannot manufacture time like this or like that. It will go on. It is eternal. It is eternal.

Lecture on BG 13.8-12 -- Bombay, October 2, 1973:

Jñāne prayāsam udapasya namanta eva san-mukhāritaṁ bhavadīya-vartam. This is the statement of Brahmā, that one should give up the nonsense process of mental speculation, "God may be like this; God may be like that." No. God is not manufactured by your mental speculation. God is God always, Kṛṣṇa. Kṛṣṇa is God from the childhood. When He was three months old He demonstrated His godly powers. He immediately killed Sakaṭāsura. He immediately killed Putanā. So He did not become God by meditation, manufactured in some mystic factory. God is God. God is always God. Even when He is child, when He is young man, when He is a boy. Kṛṣṇa, when He was a boy of seven years old, He lifted the Govardhana Hill. That is God. Not that "Here is a man. By mystic power He has become God." No. That God is different God. Real God is always God.

Lecture on BG 13.15 -- Bombay, October 9, 1973:

If you actually can understand Kṛṣṇa through devotional service... Not by challenging, not by mental speculation, not by meditation, not by fruitive activities, no. If you actually become a devotee and develop the consciousness of love for Kṛṣṇa, then God will be appreciated, God will be seen. Nāhaṁ prakāśaḥ sarvasya yoga-māyā (BG 7.25). Otherwise He'll not be visible. He's not exposed to the nondevotees.

Lecture on BG 13.18 -- Bombay, October 12, 1973:

Because we are so much influenced by the material world, especially in this age of Kali, the age of misunderstanding and quarreling, that people are... Mandāḥ sumanda-matayo manda-bhāgyā hy upadrutāḥ (SB 1.1.10). Prāyeṇālpāyuṣaḥ kalāv asmin yuge janāḥ. In this age their life is very short. Span of life is very short. And manda, all bad, not good men. Manda. And even there are so-called good men, they have their own process of knowledge, speculative process, godless. The main basic principle of speculative process is to avoid Kṛṣṇa, to avoid God. There are so many commentaries on Bhagavad-gītā to make Kṛṣṇa nil. That is mental speculation. Somebody is saying that in the there is karma only recommended. Somebody says jñāna. Somebody says yoga. Somebody says bhakti.

Lecture on BG 15.15 -- August 5, 1976, New Mayapur (French farm):

Prabhupāda: There is, that possibility is always. Just like the fire spark. Because it is spark, some way or other, if he falls down from the fire it is extinguished. That possibility is always there. Because it is small, there is possibility of being extinguished.

Devotee: He's asking can we stop mental speculation immediately.

Prabhupāda: You must stop immediately. (laughter) Mental speculation is simply nonsense. That's all right.

Devotees: Jaya! Haribol!

Lecture on BG 18.67 -- Ahmedabad, December 10, 1972:

What is that? Mānuṣya? That is mental speculation. Kṛṣṇa is asamaurdhva. Nobody can become Kṛṣṇa, nor even equal to Kṛṣṇa. Ekale īśvara kṛṣṇa āra saba bhṛtya. Only master is Kṛṣṇa and everyone is servant. This is our real position. Everyone.

ekale īśvara kṛṣṇa āra saba bhṛtya
yāre yaiche nācāya se taiche kare nṛtya
(CC Adi 5.142)

According to the direction of Kṛṣṇa, we are dancing in different activities. Sarvasya cāhaṁ hṛdi sanniviṣṭo mattaḥ smṛtir jñānam apohanaṁ ca (BG 15.15). Kṛṣṇa is situated in everyone's heart. I wanted to do something, desire; Kṛṣṇa reminds me: "Now here is the opportunity. I give you opportunity. Now you can do it." Mattaḥ smṛtir jñānam apohanaṁ ca. So if you want to forget Kṛṣṇa, Kṛṣṇa will give you such intelligence that you'll forget Him. And if you want to serve Kṛṣṇa, Kṛṣṇa will give you such intelligence as you'll be able to serve Kṛṣṇa.

Srimad-Bhagavatam Lectures

Lecture on SB 1.2.3 -- London, August 24, 1971:

We must come this side or that side. So even if we are liberated, if we are not engaged in the activities of liberation, then we are to be considered on the marginal stage. And marginal stage means we may fall down in this material condition. Āruhya kṛcchreṇa paraṁ padaṁ tataḥ patanty adho 'nādṛta-yuṣmad-aṅghrayaḥ (SB 10.2.32). Āruhya kṛcchreṇa. Kṛcchreṇa means with great difficulty. The philosophers, they try to understand the Absolute Truth by mental speculation. But simply by mental speculation you cannot stay in that understanding. Or, in other words, by theoretical knowledge you cannot escape. It must be practiced. Practiced.

Lecture on SB 1.2.5 -- Aligarh, October 9, 1976:

In the Bhagavad-gītā, the matter, five elements, earth, water, air, fire, sky, mind, intelligence, ego, these are material nature. Prakṛti me bhinnā aṣṭadhā. Apareyam. Then Kṛṣṇa says this is aparā. Aparā means inferior. Bhūmir āpo 'nalo vāyuḥ. The modern scientist or philosophers, they are engaged in studying this inferior nature. They have no information of the superior nature. But Kṛṣṇa says that these five elements, eight elements. Five gross and three subtle. The mind is also material. Khaṁ mano buddhir. These are material. People think this mental speculation, poetry, philosophy, that is spiritual. No. So long the subject matter is material, the concoction of the mind, speculation of the mind, the so-called philosophy, is also material.

Lecture on SB 1.2.6 -- London, August 26, 1971:

So because He has got transcendental qualities to attract everyone, He can attract the richest man, He can attract the most beautiful man or woman, He can attract the most strong man, He can attract the most wise man; therefore He's all-attractive. So adhokṣaja means you cannot perceive. You cannot have any actual idea of God by your mental speculation. He is called adhokṣaja.

So here the definition is adhokṣaja means God, the Supreme Lord. The definition is: that principle of religion is the best by which you can develop your devotion or love for the Supreme Personality of Godhead. How nice this definition is, just try to understand.

Lecture on SB 1.2.6 -- Hyderabad, November 26, 1972:

We cannot understand God by mental speculation, that is not possible. Realization God means when God reveals unto you. Ataḥ śrī-kṛṣṇa-nāmādi na bhaved grāhyam indriyaiḥ (CC Madhya 17.136). By our these blunt senses, speculating, we cannot understand what is God. Therefore His name is Adhokṣaja, beyond material speculation. And still you have to apply your bhakti, devotion. Just try to understand. He is beyond our sense perception, but still we have to search Him out and employ our feelings of devotion, love.

Lecture on SB 1.2.6 -- Mauritius, October 5, 1975:

Prabhupāda: No, no. That is your creation. That is your creation, mental speculation. He never said yadā yadā hi hindu dharmasya glānir bhavati. He never said. Why do you speak all these things?

Indian man (3): Anyway, it has created a state of fatalism.

Indian man (2): Yadā yadā hi dharmasya glānir bhavati (BG 4.7).

Prabhupāda: Yes.

Lecture on SB 1.2.7 -- Delhi, November 13, 1973:

So God is explaining Himself personally, and He is accepted by authorities, not only in days of yore, formerly, but recently within five hundred, seven hundred years, big, big ācāryas-Śaṅkarācārya, Rāmānujācārya, Madhvācārya, Viṣṇu Svāmī-big, big ācār..., stalwart, latest within five hundred years. Śrī Caitanya Mahāprabhu, everyone accepts Kṛṣṇa, the Supreme Personality of Godhead. And these rascals are searching out what is God. Just see their rascaldom! God is here, and he is searching. So those who are searching after God, and they are, if they are making some proposition, thesis, these are all nonsense, cheating. You do not know God. You admit. That is very good. But why you are making thesis? God is not subjected to your mental speculation.

Lecture on SB 1.2.8 -- New Vrindaban, September 6, 1972:

One philosophy is theorizing something, another philosopher is theorizing something. Lots of literature. All nonsense, because it is mental speculation. I speculate in one way, you speculate in another way. You refute me, I refute you. So therefore, these talks of the body and talks of the mind, there are varieties. Nṛṇāṁ santi sahasraśaḥ apaśyatām ātma-tattvam (SB 2.1.2). Why they are engaged in so many talks? Because they do not know, apaśyatām. They have no vision of the soul, ātma-tattva. Gṛheṣu gṛha-medhinām. Gṛhamedhī, those interested simply to maintain this body, they are called gṛhamedhī.

Lecture on SB 1.2.10 -- Bombay, December 28, 1972:

So tattva-jñāna, those who are trying to understand the Absolute Truth by mental speculation or mental exercises... There are many parties, they are, they are called theosophists and many others, they are trying to understand. So those who are trying to understand the Absolute Truth by their own knowledge, not from the knowledge of the Supreme... Our process is avaroha panthā, descending process, and the Māyāvādī philosopher's policy or system is ascending policy. I want to understand the Absolute Truth by exercising my mental power—that is called ascending process or inductive process. But our process is deductive process.

Lecture on SB 1.2.11 -- Vrndavana, October 22, 1972:

So one has to know Kṛṣṇa in tattvataḥ, as He is. So this tattvataḥ means accept the process of devotional service. Tattvataḥ, Kṛṣṇa as He is, cannot be understood by the other methods, namely by mental speculation or mystic yogic exercises. Kṛṣṇa cannot be understood in that way. If we want to understand Kṛṣṇa, then we have to accept the Kṛṣṇa method, bhakti method. That is plainly spoken by Kṛṣṇa: bhaktyā mām abhijānāti (BG 18.55). Kṛṣṇa does not say that you can know Him by mental exercises or yogic practices. No. Yogi can know... Tad-gatena manasā paśyanti yaṁ yoginaḥ (SB 12.13.1). Dhyānāvasthita-tad-gatena manasā paśyanti yaṁ yoginaḥ. Yogi also, by meditation, they see Kṛṣṇa. That is real yoga. As it is explained in the Bhagavad-gītā, the first-class yogi is he who always thinks of Kṛṣṇa within himself.

Lecture on SB 1.2.11 -- Vrndavana, October 22, 1972:

People generally ask that what is the meaning of chanting this Hare Kṛṣṇa mantra. We explain, you know, chanting of Hare Kṛṣṇa mantra means immediately, directly associating with Kṛṣṇa. One has to approach Kṛṣṇa by yogic practice or mental speculation for many, many births. Bahūnāṁ janmanām ante (BG 7.19). They can come to the conclusion that "Here is Kṛṣṇa." Vāsudevaḥ sarvam iti. But if you take to this chanting of Hare Kṛṣṇa mantra without any offense, then immediately you contact Kṛṣṇa. You save so much time. Why should you wait for many, many births?

Lecture on SB 1.2.17 -- Vrndavana, October 28, 1972:

We give very much importance to the senses. The bodily concept of life means to give importance to sense enjoyment. That's all. This is bodily concept of life. So indriyāṇi parāṇy āhuḥ. They are very important. Those who are bodily, in bodily concept of life, they are addicted to sense gratification. Indriyāṇi parāṇy āhur indriyebhyaḥ paraṁ manaḥ (BG 3.42). And those who are little advanced more, they are addicted to the mental speculation. The so-called jñānīs, mental speculation. Manasas tu parā buddhiḥ. Then again you come to the platform of intelligence. Intelligence, and when the intelligence is purified, hṛdy antaḥ-stho hy abhadrāṇi, purified, simply by hearing about Kṛṣṇa, then immediately you are raised to the platform of spiritual life. This is the process.

Lecture on SB 1.2.18 -- Calcutta, September 26, 1974:

Pure devotee of Kṛṣṇa. They have no other desire. Anyābhilāṣitā-śūnyam (Brs. 1.1.11). They have no other desire. Anyābhilāṣitā-śūnyaṁ jñāna-karmādy-anāvṛtam, uncovered by the mental speculation or fruitive activities, karma-kāṇḍa. Jñāna-karmādy-anāvṛtam (CC Madhya 19.167). Not covered. If you mix up karma with bhakti, if you mix up jñāna with bhakti, or if you mix up yoga, it is contaminated. It is not pure. Pure devotional service is given by Rūpa Gosvāmī: anyābhilāṣitā-śūnyam (CC Madhya 19.167). No desire for fruitive activities or philosophical speculation or yogic, mystic yogic magic.

Lecture on SB 1.2.20 -- Los Angeles, August 23, 1972:

Therefore any religion without scientific understanding through philosophy, it is simply sentiment. It is not religion. And philosophy without religious understanding is mental speculation. That is also useless. Philosophy which does not search ultimately what is truth, what is God, that philosophy is mental speculation. And the knowledge of God without philosophy is simply sentiment. They should be combined. To understand God, our relationship with God, our duty, everything should be understood, scientifically. Bhagavat-tattva-vijñānam. Therefore this word has been used, vijñānam. Viśeṣa-jñānam. Jñānam, ordinary knowledge, and vi, when the this word is added, vi, meaning viśeṣatā, particularly, for practical application... This vijñānam.

Lecture on SB 1.2.21 -- Los Angeles, August 24, 1972:

Devotee: No meat, fish or eggs, no intoxicants, no gambling or mental speculation, and no illicit sex.

Prabhupāda: So your name is Māyāpur-candrodaya. That is Caitanya Mahāprabhu's name. (japa)

Devotee: No meat, fish or eggs, no intoxicants, no gambling, and no illicit sex life.

Prabhupāda: So your name is Nitāi-gauracandra dāsa. Hare Kṛṣṇa.

Lecture on SB 1.2.21 -- Los Angeles, August 24, 1972:

Prabhupāda: So you are Vṛndā-devī dāsī. Vṛndā-devī? Yes. Vṛndā-devī is another name of tulasī. (japa) So what are the rules?

Devotee: No illicit sex life, no intoxications, no gambling, no mental speculation, no intoxicants...

Prabhupāda: Hm, what is the name?

Devotee: ...no meat-eating, meat, fish or eggs.

Prabhupāda: So your name is Mathurā-mohana dāsa.

Lecture on SB 1.2.30 -- Vrndavana, November 9, 1972:

To understand superficially Kṛṣṇa, that "He..., He appeared in Mathurā in His uncle's prison house...," that is also nice. But one should try to understand Kṛṣṇa in fact. That fact can be revealed by devotional service. You cannot challenge Kṛṣṇa. Kṛṣṇa will reveal. Sevonmukhe hi jihvādau svayam eva sphuraty adaḥ. If we become sevonmukha, if we try to serve Kṛṣṇa as eternal servant of Kṛṣṇa, then Kṛṣṇa will reveal Himself, what He is. You cannot understand Kṛṣṇa by speculation, by mental speculation. That is not possible. Ataḥ śrī-kṛṣṇa-nāmādi na bhaved grāhyam indriyaiḥ (CC Madhya 17.136). By sense perception, you cannot understand Kṛṣṇa. That is not possible.

Lecture on SB 1.2.30 -- Vrndavana, November 9, 1972:

Panthās tu... There are many shastric evidences. Panthās tu koṭi-śata-vatsara-sampragamyo vāyor athāpi manaso muni-puṅgavānām (Bs. 5.34). So by speculation, we cannot understand Kṛṣṇa. That is not possible. By mental speculation, we cannot understand Kṛṣṇa. We have to understand Kṛṣṇa as Kṛṣṇa says, or Kṛṣṇa's devotee says, the Gosvāmīs says, Caitanya Mahāprabhu says. Then we can understand how this cosmic manifestation is created, who created, how it is created. Everything will be clear. This is the beginning of such understanding.

Lecture on SB 1.5.2 -- Los Angeles, January 10, 1968:

That means the bodily necessities, senses. First of all, the prominent factor of our existence is the senses. Therefore Bhagavad-gītā says, indriyāṇi parāṇy āhuḥ. My material existence means the sense enjoyment. That's all. And therefore in the material civilization the highest pleasure is being derived by eschewing sex life, because that is the last word. That is the last word of material enjoyment. One who has no knowledge of spiritual life, they cannot go further than sex life. One who goes still further than the platform of sense enjoyment, he comes to the mental speculation, as there are many philosophers, speculating. The meditation is also another type of mental speculation. So indriyāṇi parāṇy āhuḥ.

Bhagavad-gītā says the first prominent factor are the senses, and the next stage is the mind, mental speculation, because the senses are controlled by the mind. Mind is the central point of sensual activities.

Lecture on SB 1.5.25 -- Vrndavana, August 6, 1974:

Very simple process of awakening Kṛṣṇa consciousness. This ātma-ruciḥ... Ātma-ruciḥ means attraction for the self, or soul. There are ātmā. Ātmā means sometimes this body. Yasyātma-buddhiḥ kuṇape tri-dhātuke (SB 10.84.13). Gross materialists, they think that "I am this body." That is also ātma-ruciḥ. They are busy to maintain this body, to decorate this body, to feed this body, to satisfy the senses of the body. This is also ātma-ruciḥ, because the body is also called ātmā. So this is another ātma-ruciḥ, materialist. Then ātmā means mind also, mental speculation, very much busy in mental speculation. That is also ātma-ruciḥ. And the, the topmost ātma-ruciḥ, topmost means that is real ātma-ruciḥ, to be attracted by the self or Superself.

Lecture on SB 1.7.41-42 -- Vrndavana, October 2, 1976:

If you want to be peaceful, then accept this proposition that I am master; you are servant." Therefore Yāmunācārya said, kadāham aikāntika-nitya-kiṅkaraḥ praharṣayiṣyāmi sanātha-jīvitam: "I have troubled myself in so many lives, therefore," bhavantam evānucaran nirantaraḥ praśānta-niḥśeṣa-mano-rathāntaraḥ. He's praying, "My Lord, when I shall be constantly Your servant?" Bhavantam evānucaran nirantaraḥ. Nirantara means "always." Praśānta-niḥśeṣa-mano-rathāntaraḥ. We are being conducted by the mental speculation. So completely śānta, no more mental speculation. Bhavantam evānucaran nirantaraḥ praśānta-niḥśeṣa-mano-rathāntaraḥ. Kadāham aikāntika-nitya-kiṅkaraḥ. "When I shall become the most attentive servant," aikāntika, "no other business?" Kadāham aikāntika-nitya... Praharṣayiṣyāmi: "I shall become engladdened," praharṣayiṣyāmi. Sanātha-jīvitam. Sanātha. Those who are not Kṛṣṇa conscious, they are anātha. Anātha, just you know anātha. Anātha means no father, mother, no protection. That is called anātha. And he's aspiring to become sanātha. Sanātha means, "Yes, I have got my protector.

Lecture on SB 1.8.19 -- Chicago, July 5, 1974 :

So by mental speculation, so-called big, big philosophers, they cannot understand Kṛṣṇa. Kṛṣṇa can be understood by the mercy of Kṛṣṇa. By the mercy of Kṛṣṇa. Kṛṣṇa comes. Kṛṣṇa is visible. Premāñjana-cchurita-bhakti-vilocanena. When you are trained up how to love God, Kṛṣṇa, then Kṛṣṇa will reveal Himself, and you will see Him. Premāñjana-cchurita. Not with these eyes, but another eyes. What is that eyes? Premāñjana, love, the ointment of love, when it is smeared in your eyes, then you can see. Just like there is medicine, eye ointment, or surma, in India it is called surma. Sometimes you apply, your vision becomes very cleansed, and you can see things very nicely.

Lecture on SB 1.8.19 -- Mayapura, September 29, 1974:

So our mental speculation and advancement of education is limited between this a and kṣa, akṣa. Akṣa-ja. But Kṛṣṇa is adhokṣaja. Adhokṣaja means where these kinds of speculation, beginning from a to kṣa, will not act. Therefore His name is Adhokṣaja. Adhaḥ kṛta, cut down. (aside:) Why they are going? They are busy in some other work? Eh? Ugra-karma. Without hearing, what he will do, nonsense? Śravaṇaṁ kīrtanam, this is our main business. Śravaṇam. If you don't hear, what you will do? You will do simply sense gratification. That's all.

Lecture on SB 1.16.12 -- Los Angeles, January 9, 1974:

Yesterday we were speaking of digvijaya. So every devotee should be so sincere to Kṛṣṇa, or God, that he must execute Kṛṣṇa's mission. Kṛṣṇa Himself comes. Kṛṣṇa comes as devotee. When He came personally, He established His position as God, with all opulences, six opulences. And He asked, through Arjuna, sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja (BG 18.66). This is Kṛṣṇa's demand, "You rascal..." Because we are all parts and parcel of Kṛṣṇa. We are suffering. Manaḥ ṣaṣṭhāni indriyāṇi prakṛti-sthāni karṣati. A great struggle for existence within this material world, simply by mental speculation.

Lecture on SB 1.16.17 -- Los Angeles, January 12, 1974:

So actually, there is nothing material. Everything is spiritual. Spiritual means īśāvāsyam idaṁ sarvam (ISO 1), everything belonging to God. But when we think that "There is no God, I am God," or "It is mine," that is darkness. This consciousness is darkness. So Kṛṣṇa consciousness movement means to be situated above this material conception. Ahaṁ mameti (SB 5.5.8). Janasya moho' yam ahaṁ mameti. This conception, that "I am the proprietor, and everything belongs to me," this conception is called illusion. And this illusion increases by mental speculation. Ultimately, that mental speculator remains in darkness, but he thinks that he has become liberated. This is another darkness. Another darkness. That is described in the Śrīmad-Bhāgavatam: ye 'nye 'ravindākṣa vimukta-māninaḥ. He Aravindākṣa. Kṛṣṇa's name is... (baby starts crying) (aside:) You take him out.

Lecture on SB 1.16.17 -- Los Angeles, January 12, 1974:

So these so-called gods are accepted by so-called devotees. These are all rascaldom. Therefore it is called māninaḥ. They are thinking, by mental speculation, that "I have become God." What you have got, power? What you have done that you have become God? But they are foolish. They do not calculate the value of his, strength of his becoming God. But they are thinking of... Therefore it is called māninaḥ. Now, you can think at your home that "I am the proprietor of the Bank of America." So you may become a crazy fellow like that. But to become proprietor of the Bank of America is different thing. But these foolish men will think like that. "I am God, I am moving the sun, I am moving..." This is their meditation. Perhaps you know. These rascals, these dogs, not gods, they think like that: "I am moving the sun, I am moving the earth..." Therefore it is called vimukta-māninaḥ. Mānina, thinking, foolishly thinking. Ye 'nye 'ravindākṣa vimukta-māninaḥ.

Lecture on SB 2.1.2 -- Vrndavana, March 17, 1974:

The materialistic persons, they are interested only in sense gratification, materialistic persons. Or mental speculation. They are materialistic. There are so many big, big so-called sādhus, saintly persons, simply busy on mental speculation. They are not perfect. And those who are busy in understanding the bodily concept of life, they are also materialistic. The difficulty is that these, these materialistic persons, in different forms, they are accepted as the leaders. They are accepted as leader, as politician, as sociologist, as philosopher, mental speculator, or so-called incarnation of God, and magician, yogis, so many things. They are leading the whole society at the present moment. Therefore people are in chaotic condition.

So for them Śukadeva Gosvāmī says that they have many subject matter to hear. Śrotavyādīni... Nṛṇām, śrotavyādīni rājendra (SB 2.1.2). The Parīkṣit Mahārāja is addressed here as rājendra, the best of the kings. Rājendra, rāja, he was king, rāja. But indra means the best. Best of the... Because he was listening Śrīmad-Bhāgavatam at the point of his death, therefore he's addressed especially, rājendra, "Because you are best of the kings." Generally, people are not interested. Or course, in those days, everyone was interested. But he was the most interested-rājendra. Śrotavyādīni rājendra nṛṇām (SB 2.1.2). Nṛṇām means ordinary human beings, mostly engaged in the bodily concept of life or mental speculation, nṛṇām. Nṛṇāṁ santi sahasraśaḥ, they have got hundreds and thousands of subject matters because they are not conversant with the ātma-tattva. But those who are interested in real ātma-tattva, they are busy in understanding... Not understanding. Busy in Kṛṣṇa consciousness.

Lecture on SB 2.3.20 -- Los Angeles, June 16, 1972:

Similarly, we have got tongue, and we are lecturing all nonsense things, mental speculation, or singing in the dancing club, ho ho, ho ho, like that. So the result is that we are diminishing our duration of life in that way. The opportunity, the human form of life opportunity, is being uselessly diminished. In the previous verse we have learned, āyur harati vai puṁsām udyann astaṁ ca yann asau.. Because the sun's business is to take away your span of life gradually. So same. As the frog is calling (to) his death, the snake, "Please come here, I am here," similarly, these persons who are talking all nonsense without kṛṣṇa-kathā, they are inviting the Yamarāja, "Please come soon. I am here. I am here." This is the position. So explain.

Lecture on SB 2.4.1 -- Los Angeles, June 24, 1972:

If you hear from the right person, then tattva-niścayam, then positively you can realize self. And if you hear from some rascals, they have no connection with Vaiyāsaki, simply by dint of mental speculation, interpreting, "I think this may be this, I think this,"... What you are, nonsense? You think? We don't accept such nonsense things. It must be positively authorized. As it is said here, vaiyāsaker iti vacas tattva-niścayam ātmanaḥ. When we hear from the right person...

tad viddhi praṇipātena
paripraśnena sevayā
upadekṣyanti te jñānaṁ
jñāninas tattva-darśinaḥ
(BG 4.34)

Jñāna and tattva-darśī. Simply jñānī, simply a-b-c-d knowledge, academic education will not help. You must be jñānī, at the same time, tattva-darśī. That tattva-darśana cannot be possible by mental speculation.

Lecture on SB 3.12.19 -- Dallas, March 3, 1975:

The same example, as I have given, that I do not know who is my father, but through the authority of mother, I can see him: "Here is my father." This is called authority seeing. If mother certifies that "My dear child, here is your father," that is the only certificate, authority, you can understand who is your father. Otherwise there is no... By experimental knowledge, by mental speculation, "He may be my father, he may be my father, he may be my father..." That you go on speculating for many millions of years. Still, you will not be able to understand who is your father. But if you take the authority of your mother, immediately you understand. That is, means, adhokṣaja. You cannot speculate what is God, but if you take the authority, then you can understand God. Otherwise it is not possible.

Lecture on SB 3.25.1 -- Bombay, November 1, 1974:

So Absolute Truth is Bhagavān Himself, Kṛṣṇa Himself. So we cannot understand the Absolute Truth or the Supreme Person by mental speculation. That is not possible, especially when we are under the influence of the three modes of material nature because material nature is divided into three status: sattva-guṇa, rajo-guṇa, and tamo-guṇa. Those who are in the sattva-guṇa, they are fit for understanding the Absolute Truth. Sattva-guṇa means the brahminical qualification. Satyaṁ śamo damas titikṣā ārjavam, jñānaṁ vijñānam āstikyaṁ brahma-karma svabhāva-jam (BG 18.42). They can understand.

Lecture on SB 3.25.7 -- Bombay, November 7, 1974:

So if one is on the mental speculation, manufacturing something for the welfare of the human society, that is not possible. Human society cannot be happy without Kṛṣṇa consciousness. That's a fact. Kṛṣṇa says in the Bhagavad-gītā:

bhoktāraṁ yajña-tapasāṁ
sarva-loka-maheśvaram
suhṛdaṁ sarva-bhūtānāṁ
jñātvā māṁ śāntim ṛcchati
(BG 5.29)

If you want śānti, individually or collectively, nationally or internationally, then you must become Kṛṣṇa conscious. What is that Kṛṣṇa consciousness? The summary is that Kṛṣṇa is the supreme enjoyer: bhoktā. We are not bhoktā. We are simply servant. Just like anywhere, there is a master and the servant.

Lecture on SB 3.26.29 -- Bombay, January 6, 1975:

Therefore, in the śāstras it is advised, acintyāḥ khalu ye bhāvā na tāṁs tarkeṇa yojayet. Acintyāḥ khalu ye bhāvāḥ. Things which are beyond your perception, sense perception, acintya, mental speculation, not cintanīya... Acintya. Acintya means mentally speculating. Beyond that, acintya, you cannot think of how this pealike form develops into such a big brain or small brain. The hands, legs, and the mechanical process of different body... This is a machine. In the material world we manufacture machine, manufacturing different parts and assembling them. (aside:) The child may be... But this machine is automatically developing. There is no question of manufacturing each part and then assembling. It is yantra. This body is yantra, machine.

Lecture on SB 3.26.35-36 -- Bombay, January 12, 1975:

The system is required provided if you make progress towards the realization of the Supreme. But if you simply follow a system but do not make advance in the matter of realizing the Supreme, then, according to Śrīmad-Bhāgavatam or according to the Vedic version, it is simply labor of love. It has no value. Therefore Bhāgavata says, "That is first-class religion system." It doesn't matter you call it Hindu or Muslim or Christian or Buddha. "That is first-class religion which helps you progressing in realization of the Adhokṣaja." Adhokṣaja, another name of Kṛṣṇa. Adhokṣaja means the subject matter which you cannot understand simply by mental speculation or by empiric knowledge, by exercising and empiric knowledge. That is called Adhokṣaja. Adhah-kṛtaṁ akṣa-jaṁ indriya-jñānaṁ yena.

Lecture on SB 5.5.2 -- Boston, April 28, 1969:

Now, in the last meeting we have discussed that this life is meant for self-realization. This human form of life especially... We must always remember that many, many years ago, not thousands—millions of years ago... In the modern civilization they have no history more than three thousand years. Some of the rascals, they say that ten thousand years before there was no human being. So this is going on, mental speculation. But we have got Vedic history, millions and millions of years. There are different species of life always. It is not that..., that only one species of life was existent and then gradually they have come to... This theory is not reasonable, neither acceptable. That is a long story.

Lecture on SB 5.5.2 -- Hyderabad, April 11, 1975:

This body means the senses, different types of senses. Sense objects, the mind. They have twenty-four elements analyzed by the Sāṅkhya philosophy. So when we think of our body, means we are interested with sense gratification. Then, a little forward, we are interested with the mind. First of all body, this gross body made of five, earth, air, fire, water, and ether. Then we become interested with the mental speculation, psychology—thinking, feeling, willing. So indriyāṇi parāṇy āhur indriyebhyaḥ paraṁ manaḥ (BG 3.42). Mind. The mental speculators, the jñānīs, they are better than the karmīs. Karmīs means who are simply entrapped with this sensual gratification, that's all.

Lecture on SB 5.5.2 -- Hyderabad, April 11, 1975:

As you are associating with the different modes of material nature, the prakṛti, material nature, by pulling your ear, "You'll come on here. Take this body." "No, I don't want." "No, that is not your discretion. Now you have infected, you see. You must take this body." This risk is there. And just to forget ourself we sometimes say, "No, there is no life after death." Why there is no life after death? You were a child. The child became a boy, the boy became a young man, the young man became an old man, and what is the old man? He must have a body, next body. That is not simply mental speculation. This is confirmed by the most exalted authority, by Kṛṣṇa. Tathā dehāntara-prāptiḥ. Dehino 'smin yathā dehe kaumāraṁ yauvanaṁ jarā, tathā dehāntara-prāptiḥ (BG 2.13). As you have changed your body in so many ways from babyhood to childhood, childhood to boyhood, boyhood to youthhood, then, similarly, dehāntara-prāptiḥ.

Lecture on SB 5.5.2 -- Hyderabad, April 11, 1975:

Therefore it is said, mahat-sevāṁ dvāram āhur vimukteḥ (SB 5.5.2). Don't manufacture. That is not... Kṛṣṇa says mām ekam. You cannot say, "Then any path will be easy." No. Bhaktyā mām abhijānāti (BG 18.55). If you want to know Kṛṣṇa, then you have to accept bhakti, nothing else. Kṛṣṇa never says jñāna or yoga or karma will help you. No, that will not help. That will entangle you more and more—again repetition of birth and death. But if you take bhakti-yoga as Kṛṣṇa says, bhaktyā mām abhijānāti (BG 18.55)... He never says, Kṛṣṇa, that "By mental speculation or by fruitive activities or by gymnastic of the yoga system..." No. Yoginām api sarveṣām.

Lecture on SB 5.5.2 -- Johannesburg, October 22, 1975:

That process is recommended by Caitanya Mahāprabhu. Not it is His manufactured process, but it is recommended in the Vedic śāstra. What is that? Jñāne prayāsam udapāsya namanta eva. The process is: don't try to speculate on God. Give up this process, this bad habit. You cannot speculate. No. Jñāne prayāsa. This is called jñāna. Jñāna means knowledge, acquired knowledge. Everyone is trying to... Nobody is interested now to understand what is God, but there are some. But they are trying to understand God by mental speculation.

Lecture on SB 6.1.7 -- San Francisco, March 1, 1967:

Vedic way is to receive knowledge from the authority, not to manufacture knowledge by mental speculation. Manufacturing..., your manufacturing process is very poor because you are imperfect. At least your senses, by which you will produce knowledge... Sense, there are senses to acquire knowledge. Just like by hearing, I have acquired knowledge, and by speaking, I am distributing knowledge. So these are all sense activities. But our senses are imperfect; therefore we cannot manufacture knowledge. We have to receive knowledge from the authority. Just like we receive knowledge from our father, mother, "This is this." The child learns, "This is lamp." The father tells, "My dear boy, this is called lamp," and the boy understands, "This is lamp." The mother says, "My dear boy, this is your father," and the boy accepts, "This is my father." He doesn't make any research "Who is my father?" because mother is the authority.

Lecture on SB 6.1.8 -- Los Angeles, June 21, 1975:

You have got this boon, this human form of life, after many, many births, evolutionary process. Don't you see so many different varieties of life? And you had to undergo through all these life. Now you have come to human form of life, so you should utilize it."

So that full utilization is how to become Kṛṣṇa conscious. That we shall come, one after another. This karma-kāṇḍīya vicāra, this will not help us. That will be discussed in the next verse. Neither the mental speculation will help us. Unless we come to the platform of bhakti and fully surrender to Kṛṣṇa and take to Kṛṣṇa consciousness business, it is very, very difficult. We will have to continue. In many places, śāstra, it is said.

Lecture on SB 6.1.13-14 -- Los Angeles, June 26, 1975:

So intelligent man should learn what is God from the Vedic information. Don't manufacture God. Manufacture..., how we can manufacture God? That is not possible. So that is called mana-dharma. By mental concoction, mental speculation, we cannot create God. Here is the definition of God, that īśāvāsyam idaṁ sarvaṁ yat kiñcid jagatyāṁ jagat (ISO 1). Idaṁ sarvam. Sarvam means whatever you see. You see the big Pacific Ocean. That is created by God. It is not that He has created one Pacific Ocean, therefore His all chemicals, hydrogen and oxygen finished. No. There are millions and trillions of Pacific Ocean floating in the sky. That is God's creation. There are millions and trillions of planets floating in the sky, and there are millions and trillions of living entites, seas, and mountains, and everything, but there is no scarcity. Not only this universe, there are millions and trillions of universes.

Lecture on SB 6.1.15 -- Honolulu, May 15, 1976:

So by karma we cannot become perfect perpetually. Just like I have given several times the example that in spite of so much education and universities and advancement of civili..., nobody is perfect in the modern civilization, not even honest. In spite of education, so much learning... I have given this example many times. This is tested in the airport, that everyone is examined about his dishonest. That means nobody is honest. So this will not help. If you want to make the world perfect, then not by karma, neither by mental speculation. That is not possible. The only means is bhakti, especially in this age. In this Kali-yuga people are very much embarrassed. Mandāḥ sumanda-matayo manda-bhāgyā hy upadrutaḥ (SB 1.1.10). Manda-bhāgyā. Even nobody is happy in his family life, so unfortunate, manda-bhāgyā. That is practical. So these things will not help, especially in this age.

Lecture on SB 6.1.24 -- Chicago, July 8, 1975:

So this process is recommended to realize God. Yadi... If somebody follows this process without mental speculation and if he has got intelligence, by hearing from the realized soul, he will realize everything. Kṛṣṇa will also help him from within. Guru means Kṛṣṇa without, and Supersoul means Kṛṣṇa within. So Kṛṣṇa is so kind that He is ready to help us from within and without, both ways. We have to take advantage of this.

Lecture on SB 6.1.28-29 -- Honolulu, May 28, 1976:

He has reached up to the point of soul. Otherwise, all Western philosophers, they're on the mental platform. So anyway, we have to go farther, farther. So the dreaming is the function of the subtle body, namely mind, intelligence and false ego. You're not free, the subtle body. So those who have no knowledge how material things are acting, covering the soul, they utmost they can think of the mind, the activities of the mind—thinking, feeling, willing, psychology, or writing some books, some mental speculation philosophy. They think this is final. That is not final. You have to go farther to the intellectual platform, then egoism, then soul.

Lecture on SB 6.1.34-39 -- Surat, December 19, 1970:

So similarly, Yamarāja is also authority. They are authority who know exactly what is God, or Kṛṣṇa, and they can direct. Therefore śāstra says you have to follow the authority. Otherwise it is not possible. Dharmasya tattvaṁ nihitaṁ guhāyāṁ mahājano yena gataḥ sa panthāḥ (CC Madhya 17.186). You cannot understand the path of religion by your mental speculation. Dharmāṁ tu sākṣād bhagavat-praṇītam (SB 6.3.19). Dharma, religious principles are enacted by the Supreme Personality of Godhead.

Lecture on SB 6.1.37 -- San Francisco, July 19, 1975:

So it is said that the Brahmā is the first living being who understood Vedas. So how he understood? Where is The teacher? There is no other creature. How he understood Vedas? Now, that teacher was Kṛṣṇa, and He is situated in everyone's heart. Īśvaraḥ sarva-bhūtānāṁ hṛd-deśe arjuna tiṣṭhati (BG 18.61). So He is teaching from the heart. So Kṛṣṇa teaches—He is so kind—as caitya-guru, from the heart, and He sends His representative from outside. Caitya-guru and guru, both ways, Kṛṣṇa is trying. Kṛṣṇa is so kind. So therefore Vedas, they are not man-made books. Veda, apauruṣeya. Apauruṣeya means not made by... We should not take Vedas as ordinary mental speculation book.

Lecture on SB 6.1.40 -- Los Angeles, June 6, 1976:

If some person, great philosopher of this material world, he thinks, he says "I believe," and he writes something, that is nonsense. That is not Veda. Because he is a created being, and as created being he has got four defects. The most important defect is that his senses are imperfect. Therefore by sense perception, by so-called mental speculation, whatever he creates, that is defective. That is not perfect knowledge. Perfect knowledge is there, Veda, because Vedas existed before the creation. And whatever there is within the creation, they're imperfect. Therefore it is clearly said that vedo nārāyaṇa sākṣāt. As Nārāyaṇa is beyond this created, manifested cosmic manifestation, similarly Vedas also are like that.

Lecture on SB 6.1.55 -- London, August 13, 1975:

"Nanda-kiśora, what I have got? I have got this body, and I have got some mental speculation, and maybe I have got some house and family. So everything I surrender unto You." This is called full surrender.

Lecture on SB 6.3.12-15 -- Gorakhpur, February 9, 1971:

That Bhṛgu dared to kick on the chest of Viṣṇu, being contaminated by the brahminical... "I am so great. I can do that." So when such great personalities like Bhṛgu Muni, Parāśara Muni, er, I mean to say, Vasiṣṭha, and Ātreya, they are so much contaminated, what to speak of others? How they will understand the Supreme Personality of Godhead by mental speculation? They will conclude naturally, "Imperson." That's all. It is not possible for them. Only the devotees, they can understand what is the actual identification of the Absolute Truth. Yasyehitaṁ na viduḥ spṛṣṭa-māyāḥ sattva-pradhānā api kiṁ tato 'nye. What others can do it.

Lecture on SB 6.3.12-15 -- Gorakhpur, February 9, 1971:

So here it is said, yaṁ vai na gobhir manasāsubhir vā hṛdā girā vāsu-bhṛto vicakṣate. (reads commentary) Tan māyā-mohitād na jānanty ity uktam, avaśed tata tasya ityāhayam iti. Gobhir indriyair cittena na vicakṣata na paśyanti.(?) So gobhiḥ, by sensual gymnastic or mental speculation, the Supreme Personality of Godhead cannot be understood. There are many mental speculator, just like Aurobindo Ghosh. So he speculated.

Lecture on SB 6.3.12-15 -- Gorakhpur, February 9, 1971:

The whole world, nirviśeṣa-śūnyavādi... Nirviśeṣa... Means the impersonalists and voidists, that's all. They have no understanding what is Personality of Godhead. Gobhir indriyair hṛdā cittena na vicakṣate. One cannot, a gobhiḥ, by exercise of the senses. Gobhiḥ and indriyair hṛdā, heart also, meditation. The jñānīs, the speculators, they are speculating by sensual activities, and the yogis, they are trying to find out the Supreme within the heart, cittena. So na paśyanti: "But they cannot see." They cannot see. So jñānīs, the yogis, they cannot understand. Although they are trying for it, they cannot understand. It is clearly said, hṛdā girā vāsu-bhṛto vicakṣate. Yad vāca nābhūd dhṛtaṁ yan manaḥ manute ityādi śruteḥ.(?) And he is giving recitation from the Vedas: yad vāca nābhūd dhṛtaṁ yan manaḥ manute ityādi śruteḥ. Avann mānasa-gocaraḥ.(?) He is beyond the reception of mental speculation or philosophical topics.

Lecture on SB 6.3.18-19 -- Gorakhpur, February 12, 1971:

Devotee means a pure devotee. Contaminated devotee is different. Dvidha(?)-bhakta and śuddha-bhakta. Those who are contaminated with material desires, with fruitive activities and mental speculation, they are contaminated devotees. They are not pure devotees. Pure devotees means anyābhilāṣitā-śūnyam (Brs. 1.1.11), no material desires, no action and fruitive activities, no mental speculation. So he is pure devotee. So that pure devotee in transcendental position is always protected by the Lord. And His Viṣṇudūta is wandering everywhere. Just like Ajāmila. As soon as he was arrested by the Yamadūtas, immediately they approached. So as there are different police department, military police department, civil police department, similarly, there is transcendental police department. Don't be afraid. Yes, here it is stated. So simply we have to be sincere devotee, and all protection will be given by Kṛṣṇa.

Lecture on SB 6.3.20-23 -- Gorakhpur, February 14, 1971:

Akṣa means direct experience, direct seeing, direct touching. And ja means born. Knowledge born of direct perception of the senses—this is called akṣaja. And adhaḥ means where akṣaja, the direct perception of material senses, is cut down. (curbed?) There is no possibility. He is called adhokṣaja. Therefore, Kṛṣṇa's another name is Adhokṣaja, "beyond the sense perception knowledge." Panthās tu koṭi-śata-vatsara-sampragamyaḥ. We cannot understand God or religion by our mental speculation even by the speed of mind, manasa. Panthās tu koṭi-śata-vatsara. And the speculation continues by, continues to hundreds and hundreds of years. Panthās tu koṭi-śata-vatsara. Śata means hundred, and koṭi means ten million.

Lecture on SB 7.5.22-30 -- London, September 8, 1971:

Prahlāda Mahārāja at the age of five years only he was a great devotee. Prahlāda Mahārāja is one of the mahājanas, great authorities of this line, devotional line. (aside:) You can take your seats. To understand God and to understand our relationship with God, it is not to be done by mental speculation. It is not possible. God is not so cheap thing that one can understand by mental speculation. In the present age people are very much fond of mental speculation. In the śāstra it is said, tarko apratiṣṭhaḥ: (CC Madhya 17.186) "Simply by arguing you cannot come to the right conclusion." You may be very good arguer, but another arguer may defeat you by his argument. So in this way, simply by dry arguments it is not possible to come to the conclusion.

Lecture on SB 7.5.30 -- London, September 9, 1971:

Nobody goes to take instruction from anyone unless one accepts a guru, or spiritual master. So even one has got nice guru, he cannot also get Kṛṣṇa consciousness if he has determined himself to remain in this material world. Matir na kṛṣṇe parato svato vā. And svato. Svataḥ means by mental speculation, judging, considering oneself personally. And parato means taking instruction from others. Matir na kṛṣṇe parato svato vā mitho 'bhipad... Mitha, meeting. Just like we are talking about Kṛṣṇa consciousness in this meeting. Mitha, mitha means in assembly. So gṛha-vratānām. If our determination is that "I shall remain in this material world, I shall enjoy this material life," then Kṛṣṇa consciousness is impossible.

Lecture on SB 7.5.30 -- Mauritius, October 2, 1975:

So father was challenging his son, "Where you got this Kṛṣṇa consciousness?" So the son replied flatly that matir na kṛṣṇe parataḥ svato vā: "My dear father, this Kṛṣṇa consciousness cannot be achieved by speculation or by hearing from others." Matir na... Parata means hearing from others, and svataḥ, svata means personally by mental speculation or philosophical speculation. Mitho. Mitho means by congregational meeting, by conferences. Why? Now, gṛha-vratānām. If one is addicted to this material way of life, he cannot understand, or cannot be convinced, about Kṛṣṇa consciousness.

Lecture on SB 7.6.1 -- Boston, May 8, 1968:

So come forward. Yes. Sit comfortably. So bhāgavata-dharma means it is scientific knowledge. It is not sentiment. Religion without philosophical understanding is sentiment. And philosophy without understanding of God is mental speculation. So we should not be both, neither sentimentalist nor dry mental speculator. There is a class of mental speculators, they're writing volumes of books but there is no substance. And there are some religious fanatics, but they do not know, do not understand what is religion. So these two classes of men are now very prominent at the present moment. But Śrīmad-Bhāgavata, or Bhagavad-gītā, if anyone is intelligent he'll know that it is combination of religious sentiment plus philosophy. To understand religion on the basis of philosophy and logic. Not blindly accepting. So this is called bhāgavata-dharma.

Lecture on SB 7.6.1 -- Montreal, June 10, 1968:

The test is, according to Bhāgavatam, svanuṣṭhitasya dharmasya. Everyone's duty, the point of perfection is saṁsiddhir hari-toṣaṇam (SB 1.2.13), whether by your duty you have satisfied the Supreme Personality of Godhead. That is the duty. Then it is perfect. You are a great scientist? Very good. But if you can prove scientifically that there is God, that is successful. Otherwise, it is nonsense. If you prove that there is no God, God is dead by scientific method, it is simply lunacy, craziness. That's all. Similarly, if you are philosopher, very expert in mental speculation and writing volumes of books, speculative, but if you can prove that there is God, then your philosophy is perfect. Any line you take.

Lecture on SB 7.6.1 -- Hong Kong, April 18, 1972:

So ordinarily we are bodily, we think I am this body. This is called... Body means my senses. So civilization based on this bodily concept of life are interested only sense gratification. That is their aim of life. Indriya. Sense gratification. And those who are disgusted with sense gratification, they go little higher on the mental platform, mental speculation. Just like philosophy, poetry, like that. Gross means they are working very hard day and night for sense gratification. Just like hogs and dogs. That is stated in the śāstra. Nāyaṁ deha deho bhājāṁ nṛloke kaṣṭān kāmān arhate viḍ-bhujāṁ ye (SB 5.5.1). Ṛṣabhādeva says that this human form of life is not meant for working so hard like cats and dogs. That is not recommended.

Lecture on SB 7.6.3 -- Montreal, June 16, 1968:

So people are trying to burnish the body and the mind. First of all they try to burnish the body. This is material civilization. Very nice clothing, very nice food, very nice apartment, very nice car, or very nice sense enjoyment—everything is very nice. But that is to this body. And when one is frustrated to this very nice arrangement, then he goes to the mind: poetry, mental speculation, LSD, marijuana, drinking, and so many things. These are all mental. Actually, happiness is not there in the body, nor in the mind. Read happiness is in the spirit. Therefore Bhagavad-gītā says, sukham ātyantikaṁ yat tad atīndriya-grāhyam (BG 6.21). The real, the ultimate happiness is that which is beyond this material senses. Ātyantikaṁ yat tad atīndriya. Atīndriya means—indriya means the senses—transcendental to the senses. That means that spiritual. There are many instructions and practical also.

Lecture on SB 7.6.6-9 -- Montreal, June 23, 1968:

Direct method: chant Hare Kṛṣṇa. That will revive your old consciousness. Chant Hare Kṛṣṇa. Caitanya Mahāprabhu says, kalau nāsty eva nāsty eva nāsty eva gatir anyathā: "In this age there is no other alternative, there is no other alternative." The so-called meditation, yoga or karma, jñāna, mental speculation—everything will fail. They are, of course, standard processes, but that is not possible to execute in the present age. What is to speak of present age, even five thousand years ago, when Arjuna was taught to learn yoga system... That is also mentioned in the Bhagavad-gītā, the practice of yoga, the sitting posture, the breathing exercise, and controlling the senses and regulating eating, sleeping.

Lecture on SB 7.6.6-9 -- Montreal, June 23, 1968:

That is also confirmed in another place, tato māṁ tattvato jñātvā: "Thus one understanding Me in truth," viśate tad-anantaram, "he is allowed to enter into My kingdom." Yāvān yaś cāsmi tattvataḥ: "Only by devotional service one can understand Me, actually what I am." So if we engage ourself in submissive way in the devotional service of Kṛṣṇa, then Kṛṣṇa will let you know what is His birth, what is His appearance, disappearance, activities—everything revealed. These things are not to be understood by mental speculation. These things are revealed to a heart of a devotee when he is engaged in devotional service. So that is the process of Kṛṣṇa consciousness. As you make more advance in Kṛṣṇa consciousness, you understand everything.

Lecture on SB 7.6.6-9 -- Montreal, June 23, 1968:

I don't require any authority to understand anything." But the Vedic literature, the Vedic civilization, they direct, tad-vijñānārthaṁ sa gurum evābhigacchet: (MU 1.2.12) "If you want to understand that science, you must approach a bona fide spiritual master." This is very simple thing. If you want to learn engineering, then you must admit yourself in engineering college. If you want to be a medical man, you must admit yourself in a medical college. Similarly, if you want to understand Kṛṣṇa, then you must approach a person who knows Kṛṣṇa. It is not fanaticism or mental speculation. You have to learn the art scientifically.

Lecture on SB 7.6.20-23 -- Washington D.C., July 3, 1976:

So here, our position in this material world: darkness. We are simply speculating in so many ways what is the ultimate cause. There are so many philosophers, but they are speculating only without any definite knowledge. So śāstra says that speculative knowledge will not be successful at any time. In the Brahma-saṁhitā it is said that panthās tu koṭi-śata-vatsara-sampragamyo vāyor athāpi manaso muni-puṅgavānām (Bs. 5.34). Manaso, by mental speculation, muni-puṅgavānām, one who speculates, he is called muni.

Lecture on SB 7.7.29-31 -- San Francisco, March 15, 1967, (incomplete lecture):

This hard life, this working day and night simply for sense gratification, oh, it is not good. They are trying something else. So generally they come to enjoy mental speculation. Just like the karmīs, they are trying to satisfy their senses, similarly, the jñānīs, they want to satisfy their mind. Their mind It is a little more elevated. But still, they are on the material platform because these senses and mind and intelligence, up to intelligence, that is all matter. There is no question of spiritual understanding. Mental speculation, speculators, they are not on the spiritual platform. They are on the material platform.

Lecture on SB 7.9.8 -- Calcutta, March 5, 1972:

So they offered Nṛsiṁha-deva their prayers to pacify Him, but they could not. Therefore, Prahlāda Mahārāja says that if brahmādayaḥ sura-gaṇā siddhāḥ. Here Śrīdhara Swami says munayo manana śīla siddhyaḥ jñanino 'pi (?). Manano śīla, manano śīla means speculator, philosophers. Muni means one who can think very deeply, manano śīla. Those who can explain(expand?) by thinking, feeling, and willing and can write volumes of books. There are many you know in our country, they are called manano śīla. They take pleasure by mental speculation, manano śīla, and they are men of knowledge also, jñanino 'pi. (Sanskrit quotes from Śrīdhara Swami commentary) And what kind of...? These great sages and saintly persons, what is their qualification? They are situated in knowledge, in sattva-guṇa, in light. They are not in darkness. Although they are not in darkness, but without being in the platform of sattva-guṇa, nobody can become very intelligent person, philosopher, or mental speculator also. Their position is very high in the material calculation. So such persons, api, (Sanskrit quotes from Śrīdhara Swami commentary), they are also unable to satisfy.

Lecture on SB 7.9.8 -- Mayapur, February 28, 1977:

So Prahlāda Mahārāja, although he does not belong to this platform of mental speculation... He is nitya-siddha. He has no chance because he's always thinking of Kṛṣṇa. (loud electrical noise) (aside:) What is that? Sa vai manaḥ... Sa vai manaḥ kṛṣṇa-padāravindayor (SB 9.4.18). Practice this very simple thing. Kṛṣṇa is here. We see the Deity daily and see the lotus feet of Kṛṣṇa. Fix up your mind in that way. Then you are safe. Very simple thing. Ambarīṣa Mahārāja, he was also a great devotee. He was king, very responsible person, politics. But he practiced in such a way that he fixed up his mind on the lotus feet of Kṛṣṇa.

Lecture on SB 7.9.34 -- Mayapur, March 12, 1976:

God is all-spirit, and He can be understood by spiritual method, not material method. Material method means up to the standard of mental speculation and mental concoction. That is not the way. Mano-rathena āsato dhāvato bahiḥ. In the Brahma-saṁhitā it is also said,

panthās tu koṭi-śata-vatsara-sampragamyo
vāyor athāpi manaso muni-puṅgavānām
so 'py asti yat-prapada-sīmny avicintya-tattve
govindam ādi-puruṣaṁ tam ahaṁ bhajāmi
(Bs. 5.34)

By mental speculation, mental speed, you cannot reach the spiritual world. Mental speed is very strong. Everyone, we have got experience—you are sitting here. Immediately, within a second, you can go to our London temple by the mental speed. So even by the mental speed for many, many years, if we run over the space, still, we cannot reach the spiritual world. That is not possible.

Lecture on SB 7.9.47 -- Vrndavana, April 2, 1976:

So we should not imitate Haridāsa Ṭhākura. But we should... My Guru Mahārāja used to say, man tumi kisera vaiṣṇava. It is mental speculation that "I shall do like that. Raha, I shall... In a secluded place, I shall chant." You cannot do that because your mind is not yet trained up. It is for the highest perfection stage that anywhere one can sit down and chant Hare Kṛṣṇa and remain happy. That is not possible for the ordinary stages. Therefore my Guru Mahārāja criticized, man tumi kisera vaisnava. Because it is all mental speculation, therefore he's chastising his mind, "My dear mind, you have become a Vaiṣṇava?" Man tumi kisera vaiṣṇava, pratiṣṭhara tāre nijanera ghare, tava hari-nāma kevala kaitava: "In a secluded place, sitting down, chanting Hare Kṛṣṇa, for you it is simply to get some material adoration and cheating the people." He has said like that. Don't try to do that. Always be engaged actively in Kṛṣṇa's activities.

Lecture on SB 7th Canto -- Calcutta, March 7, 1972:

One's business should be that he may not change his position. Means he may remain a gṛhastha, he may remain a brāhmaṇa or śūdra or a sannyāsī, it doesn't matter. In whatever position he is, he is all right. The only business is that you should not be proud of mental speculation, jñāna-tyāga. You have to give up this practice of mental speculation, but you try to understand the Supreme Lord by hearing from a realized soul. San-mukharitāṁ bhavadīya-vārtām. Then the result will be gradually, although the Supreme Lord is never conquerable, still He will be conquered. Ajito 'py jito 'py asi. Ajita, nobody can conquer. But simply by hearing about Him, you go on hearing, hearing about Him, one day you will find that the Supreme Lord has been conquered by you, you have become victorious.

Nectar of Devotion Lectures

The Nectar of Devotion -- Bombay, December 28, 1972:

The rascals, they will not understand Kṛṣṇa as Kṛṣṇa says. The rascal will mislead other and mislead himself. He'll go himself to hell and he'll drag all others to the hell. This is going on. This is going on. Everything is there, very plain and clear. One has to act according to that. He gets the benefit. But they, they will not allow. These rascal leaders, they'll not allow. They will be represent Kṛṣṇa as something else. The, the only business is to kill Kṛṣṇa. That's all. Not to accept Kṛṣṇa is fact. All the big commentaries on Bhagavad-gītā, you'll see. They're simply trying to make Kṛṣṇa is not a fact. It is some fictitious. It is some story, mental speculation. This is their business. Demonic. So the condition is very, I mean to say, dangerous. People are being misled.

The Nectar of Devotion -- Bombay, December 28, 1972:

We get knowledge from the superior. Everyone gets knowledge from the superior. Nobody gets knowledge automatically. That is not possible. So things which are beyond the perception of our senses, how we can get that knowledge? By our mental speculation, it is not, never perfect. We give sometimes this example: Just like we, if we want to know who is my father, that is not possible to know simply by mental speculation. If we approach the authority, mother, we get the knowledge immediately. So knowledge from the authority is perfect. Knowledge by mental speculation is always imperfect. This is our conclusion. If you get knowledge, any knowledge, from the perfect, that knowledge is perfect. And if you get knowledge from imperfect, that knowledge is always imperfect. This is our process. Therefore the Vedas says: tad vijñānārthaṁ gurum eva abhigacchet. One must approach the superior who is in knowledge. Then he gets the knowledge.

The Nectar of Devotion -- Vrndavana, October 30, 1972:

They'll make their own interpretation. Such is the horrible condition. They'll try to make minus Kṛṣṇa Bhagavad-gītā, go on reading Bhagavad-gītā for millions of years, setting aside Kṛṣṇa. That is scholarly. This is going on. Scholar means they say, openly... I have seen Dr. Radhakrishnan. When he's explaining man-manā bhava mad-bhakto mad-yājī māṁ namaskuru (BG 18.65), he's saying openly, "It is not to the person Kṛṣṇa." He's saying. Just see the attempt. He's writing comments on Bhagavad-gītā and he's trying to make Kṛṣṇa away, minus Kṛṣṇa. Simply mental speculation. This is going on.

The Nectar of Devotion -- Vrndavana, November 10, 1972:

So jñāna-karmādy-anāvṛtam: (CC Madhya 19.167) "Devotional service should not be contaminated by jñāna-kāṇḍa, karma-kāṇḍa, by fruitive activities or mental speculation." Devotional service should be taken exactly in the line of the great authorities. Just like our sampradāya, Gauḍīya Vaiṣṇava sampradāya, they are following... Rūpānuga.

Sri Caitanya-caritamrta Lectures

Lecture on CC Adi-lila 1.9 -- Mayapur, April 2, 1975:

So these are the Vedic calculation. And not only that, there are different species of life, and how they are working, what senses are predominant in each and every life and everything is described. Everything is very minutely described. Therefore, if we want to have knowledge, you cannot do it by mental speculation. We should know that our mind is very, very limited. Simply by theorizing, it is not possible. Therefore tad-vijñānārthaṁ sa gurum eva abhigacchet sampit-pāṇiḥ śrotriyaṁ brahma-niṣṭham (MU 1.2.12). So we have to know from the supreme authority or the Vedas. Then the knowledge will be perfect.

Lecture on CC Adi-lila 7.3 -- Mayapur, March 3, 1974:

Everything should be understood in truth. So our, this Kṛṣṇa consciousness movement is trying to understand the Absolute Truth. So in another place Kṛṣṇa says, janma karma me divyaṁ yo jānāti tattvataḥ: (BG 4.9) anyone who understands the Absolute Truth factually as He is, not by mental speculation, but by the paramparā system... So therefore, the author of Caitanya-caritāmṛta is beginning with guru, pūrve gurv-ādi. Beginning is the guru, the spiritual master, because he is the representative of the paramparā system, disciplic succession. Therefore, whatever we do, we must first of all try to understand from guru.

Lecture on CC Adi-lila 7.39-47 -- San Francisco, February 1, 1967:

Just the only benefit of such exercises is to concentrate the mind. The mind is very disturbed. So that is also materialist. That means jñānī, yogi and karmī. Karmī means those who are working very hard day and night simply for sense gratification. That's all. They are called karmīs. And jñānī means they are finding out solution by mental speculation. And yogi means they are trying to find out spiritual salvation by bodily exercises. They are all, in strict sense, they are all materialist. There is no question of spiritualist. Spiritualism (means) there where one understands that what is the constitutional position of spirit and act according to that. Therefore bhakti, this devotional service, is only spiritualism because those who are devotees, they know that they are eternally part and parcel of the Supreme Lord, and therefore to be engaged in transcendental loving service of the Supreme Lord is spiritualism.

Lecture on CC Madhya-lila 20.100-108 -- Bombay, November 9, 1975:

So simply mental speculation, the whole world, the scientists... They are working on the mental platform. Therefore today they fix up, "This is the conclusion," and tomorrow, another conclusion, another conclusion, because it is mental platform. So above the mental platform, intellectual platform, and above the intellectual platform is the spiritual platform, and that is called Brahman platform. So athāto brahma jijñāsā. One should be inquisitive on the spiritual platform. That is success of life.

Lecture on CC Madhya-lila 20.100-108 -- Bombay, November 9, 1975:

Therefore Kṛṣṇa, when He appeared on this planet, His last instruction was that sarva-dharmān parityajya mām ekaṁ śaraṇaṁ: (BG 18.66) "You just surrender to Me, and after giving up all your mental speculation, so-called religious system..." This is real religious system. So He left behind Him the Bhagavad-gītā to open our eyes, but we did not take much care of it. Therefore five hundred years ago Lord Caitanya appeared. He is Kṛṣṇa. He practically taught how to accept instruction of Kṛṣṇa.

Lecture on CC Madhya-lila 20.118-119 -- New York, November 23, 1966:

If you want to worship the Supreme Lord, then you have to worship Him simply by service. There is no other process. You cannot worship Kṛṣṇa by this controlling breathing or by mental speculation or by some pious activities or by charities. You have simply to worship Him simply by your devotional love. That is the only way. Bhaktyai, bhaktyaika, only one, bhakti. There is no other means. There is no second means to understand God without this devotional service. Rest assured. Foolish creatures, they take this, that. They do not understand. They come to the, that impersonal, void, all the nonsensical conclusions and... Because they do not take shelter of this, devotion, therefore they cannot have any conclusion. It is not possible. Therefore, more or less, they become atheists or after the voidness or impersonalism, and so many things there are. They create.

Lecture on CC Madhya-lila 20.318-329 -- New York, December 22, 1966:

So in one breathing of Mahā-Viṣṇu, you cannot calculate how many Manus are there. This is called unlimited. We say "unlimited," but we should have some knowledge how it is unlimited. There is no question of counting the energies displayed by the Supreme Lord in so many ways. Because we cannot explain something, we dismiss the whole thing. "There is void, nothing. Void." Because my mind, my intelligence, cannot go so far, we say, "Perhaps, maybe it was like this." So this is all mental speculation.

Lecture on CC Madhya-lila 20.330-335 -- New York, December 23, 1966:

The higher caste were made not artificially. They had to follow nine great principles, then they are higher caste, not by rubber stamp, just like Gandhi wanted to do, taking the banghis, the sweepers, and rubber-stamping "harijana." No. This is a process. Everyone is open to become a harijana, but not by rubber stamp but by training. That training is required. People are avoiding the training and simply speculating in the mind, foolishness. How the world can improve? There must be training. Without training, simply by mental speculation, one can make any... Manasā mathurāṁ gacchasi. Oh, you have to work. If you want to go California, you have to go there. Simply I am thinking, "I am going to California, California," will that...? No.

So similarly, actually if you want peace, then you have to work. The process is there.

Lecture on CC Madhya-lila 20.354-358 -- New York, December 28, 1966:

Celibacy means completely ceasing from sex life. Yad icchanto brahmacarya. Brahmacarya means celibacy. No sex life. Therefore the brahmacarya āśrama is recommended. The first basic principle of religious life, according to Vedic principle, the students are expected to go to the spiritual master's place and learn how to live without any sex life. For twenty-five years or at least for twenty years, the student is trained up in that way. Then he's allowed to enter into the gṛhastha life to marry. So there is a process. Religion means there must be process. It is not simply mental speculation. Yad icchantaṁ brahmacaryaṁ caranti. Yad icchantaṁ brahmacaryaṁ caranti tat te padaṁ saṅgraheṇa pravakśye. These things are described in the Bhagavad-gītā.

Sri Isopanisad Lectures

Sri Isopanisad Lecture Excerpt -- Los Angeles, July 8, 1971:

Because an authority like Sārvabhauma Bhaṭṭācārya is stating, a brāhmaṇa and... He was very learned scholar. You know Sārvabhauma Bhaṭṭācārya's name. So because he said that "He is Supreme Personality..." He did not ask any storekeeper, but he asked a learned brāhmaṇa who knows things. So similarly, we have to accept in that way. In each and every case, if we want to research, it is not possible, because our senses are blunt senses. What you can do? Acintyāḥ khalu ye bhāvā na tāṁs tarkeṇa yojayet. The śāstra says that "Things which are beyond your conception, beyond your mental speculation"—avāṅ-manasā gocaraḥ—"neither you can express by words, neither you can think of." Avāṅ-manasā gocaraḥ.

Sri Brahma-samhita Lectures

Lecture on Brahma-samhita, Verse 33 -- New York, July 27, 1971:

Our beginning is from God, but God has no beginning. Anādi. Advaita acyuta anādi ananta-rūpam, although the forms are many millions and trillions. Advaita acyuta anādi ananta-rūpam, ādyaṁ purāṇa-puruṣam. Ādyam, original. Therefore the oldest person. Kṛṣṇa, God is the original person; therefore the oldest person. Still nava-yauvanaṁ ca. But still He's always youth, youthful. Vedeṣu durlabha. To search out Kṛṣṇa by academic education, by mental speculation, by pursuits of different types of knowledge is not possible. Advaita acyuta anādi ananta-rūpam ādyaṁ purāṇa-puruṣam nava-yauvanam, vedeṣu durlabha. You cannot find out Kṛṣṇa by simply academic education. Adurlabha ātma-bhaktau. But He is available from His devotee. If you approach a devotee of Kṛṣṇa, he can deliver you Kṛṣṇa like anything: "Here is Kṛṣṇa. Take." Kṛṣṇa is so nice. He becomes a doll in the hands of devotee. He agrees. Just like before Mother Yaśodā He was trembling. Mother Yaśodā showed Him the cane.

Festival Lectures

Nrsimha-caturdasi Lord Nrsimhadeva's Appearance Day -- Srimad-Bhagavatam 7.5.22-34 -- Los Angeles, May 27, 1972:

"My dear father, don't be afraid. It is not a thing to be taught." Matir na kṛṣṇe. "Nobody can become Kṛṣṇa conscious," matir na kṛṣṇe parato, "being taught by others," matir na kṛṣṇe parataḥ svato vā, "or by mental speculation or thinking oneself," mitho 'bhipadyeta, "or by making conference meeting, religious meeting, conference." No. Three things. One thing is to learn Kṛṣṇa consciousness by speculative method, self-realization. Just like so many people are very much interested that "Why shall I go to a guru? I can realize myself. I shall meditate." So that is called svataḥ.

Nrsimha-caturdasi Lord Nrsimhadeva's Appearance Day -- Srimad-Bhagavatam 7.5.22-34 -- Los Angeles, May 27, 1972:

Therefore Prahlāda Mahārāja says, śravaṇam. If we hear about Kṛṣṇa constantly, through realized souls, not professional—if we hear, satāṁ prasaṅgān mama vīrya-saṁvido (SB 3.25.25)—then automatically, our dormant Kṛṣṇa consciousness come out. So Prahlāda Mahārāja says, therefore, that "Those who are determined to become happy within this material world, they cannot be raised to Kṛṣṇa consciousness either by personal teaching or by making conference or by mental speculation." That is not possible, because he is determined. So our duty is that we should know that in the materialistic way of life we shall never be happy. This is called knowledge.

Sri Vyasa-puja -- London, August 22, 1973:

After Brahma, Nārada, then Vyāsa. And Vyāsa is original guru, because from his literature we understand spiritual knowledge. All these literatures whatever we have produced, they are actually originally from Vyāsadeva. The four Vedas, Brahma-sūtra, Upaniṣads, Purāṇas, they are called Vedic literature. And whatever is written with the conclusion of this Vedic literature, that is also Vedic literature. Just like our books. All our books, they are not mental speculation. Whatever I have learned from my Guru Mahārāja, I am presenting. That's all. It is not mental speculation—this philosophy, that philosophy. We kick out all these things. Unless we get the knowledge from the authorized source, we don't accept.

Radhastami, Srimati Radharani's Appearance Day -- London, August 29, 1971:

So this Kṛṣṇa, when He wants to enjoy, what kind of enjoyment He will have? That has been discussed by Śrīla Jīva Gosvāmī. Kṛṣṇa is Paraṁ Brahman. Brahman, Paramātmā, then Paraṁ Brahman. Absolute Truth, three different features. Someone is realizing the Absolute Truth as impersonal Brahman. Jnanis, those who are trying to understand the Absolute Truth by mental speculation, by dint of his own knowledge, he's realizing the Absolute Truth as impersonal Brahman. And those who are trying to understand the Absolute Truth by meditation, yogis, they realize the Absolute Truth as Paramātmā. Paramātmā is situated in everyone's heart. Īśvaraḥ sarva-bhūtānāṁ hṛd-deśe 'rjuna tiṣṭhati (BG 18.61). That feature, Paramātmā feature. Aṇḍantara-sthaṁ paramānu-cayāntara-sthaṁ govindam ādi-puruṣaṁ tam ahaṁ bhajāmi. That Paramātmā feature is one expansion of Kṛṣṇa.

Arrival Addresses and Talks

Arrival Address -- Mauritius, October 1, 1975:

So unless we understand this philosophy... It is not philosophy. Philosophy you can call, because the philosophy means the science of sciences. Philosophy is not a mental speculation. Philosophy is the prime science from which all other sciences are derived. That is philosophy. So our Kṛṣṇa consciousness movement is trying to educate people on this science of sciences to understand first of all that "What you are? Are you this body or different from this body?" This is essential. And if you go on constructing your big building on a defective foundation, then it will not stay. There will be danger.

Initiation Lectures

Initiation Lecture -- Caracas, February 22, 1975:

The fact is God is called Ajita—nobody can conquer Him. But any person who gives up this process of mental speculation—that means "God may be like this. Perhaps God is like this. Perhaps this, perhaps this..." This is called mental speculation. We have to give up this mental speculation. Jñāne prayāsam means endeavor in mental speculation should be given up. One should submissively approach the spiritual master. Jñāne prayāsam udapāsya namanta eva. Namanta eva means submissively offering respect, obeisances. And after that, if you hear from the self-realized soul, jñāne prayāsam udapāsya namanta eva san-mukharitām. San-mukharitām means self-realized soul. From his mouth one has to hear. Bhavadīya-vārtām. In this way, although God is never conquered by anyone else, still, this man, who has adopted this process, he will conquer God someday.

Initiations -- Detroit, June 15, 1976:

Prabhupāda: What are the rules and regulations?

Glenn: One must not engage in meat-eating, illicit sex, gambling or mental speculation, or intoxication.

Prabhupāda: Thank you.

Puṣṭa Kṛṣṇa: Gaura dāsa.

Prabhupāda: Gaura dāsa. (japa)

Puṣṭa Kṛṣṇa: Jim from Chicago. Ann Arbor, Miles from Ann Arbor.

Dhṛṣṭadyumna: He's working, Śrīla Prabhupāda.

Prabhupāda: So, what are the rules and regulations.

Wedding Ceremonies

Initiation of Sri-Caitanya dasa and Wedding of Pradyumna and Arundhati -- Columbus, May 14, 1969:

Premāñjana-cchurita-bhakti-vilocanena santaḥ (Bs. 5.38). You cannot reach the Absolute Truth simply by mental speculation because He is beyond your mental speculation. Avāṅ-manasā gocaraḥ. Sadaiva hṛdayeṣu vilokayanti. If you are absorbed in love of Godhead, then you will see God everywhere, within your heart and outside. Premāñjana-cchurita-bhakti-vilocanena (Bs. 5.38). That real purpose is bhakti. So anywhere you be situated, you take this process of loving service to the Lord, and the Lord will reveal Himself. Lord will reveal Himself.

General Lectures

Lecture -- Montreal, June 26, 1968:

"The paṇḍitāḥ, the learned man, he does not lament over the body, either living or dead." Because bodily platform is not the subject matter for understanding of philosophical research. Bodily platform is not very important. The spiritual platform is important, but nobody is discussing about spiritual platform. Everyone is, all the education centers, the universities, they are, I mean to say, busy studying chemistry, physics, and biology, mathematics. At most, little philosophy. That is also on mental speculation, theory. Somebody is giving some theory; somebody's giving (another) theory. But nobody discussing about the eternal spirit soul. That is the defect of this modern civilization.

Class in Los Angeles -- Los Angeles, November 15, 1968:

So actually gṛha means this material confinement. Gṛha, real gṛha, means one is bound up within some limited space. So gṛha means to keep oneself within some boundary. So Bhāgavata says so long one is interested to keep himself within the boundary of some limited area, he cannot understand Kṛṣṇa consciousness. Matir na kṛṣṇe. He cannot understand what is Kṛṣṇa consciousness or God consciousness. He's limited within certain boundary. So Bhāgavata says Kṛṣṇa consciousness is not possible for persons who are limited by certain boundary, including universal concept of life. That is also boundary. And matir na kṛṣṇe svataḥ. Svataḥ means by his personal mental speculation. Just like many philosophers are thinking to reach the Absolute Truth beyond this limitation.

Lecture Engagement and Prasada Distribution -- Boston, April 26, 1969:

He is beyond our mental speculational field; He is beyond our conception, beyond our words. But there is other verses also, that athāpi te deva padāmbuja-dvaya-prasāda-leśānugṛhīta eva hi, jānāti tattvam (SB 10.14.29). One can understand what is God by the mercy of God, not by mental speculation. It is not possible. We have got very limited scope of knowledge. Our senses are imperfect, we are full of cheating propensities, and we are liable to commit mistake. These four defects are within us. However a great man one may be, he is sure to commit mistake. I shall give you one tangible example in the life of Mahatma Gandhi. You know he was a very great man, political leader in India. So he was also very God-fearing man, a very nice soul. But he also committed mistakes so many times. So to err is human. This is a fact in every person. Therefore, because we commit mistake, because we are sometimes illusioned, and because we have got a propensity of cheating others, and because our senses are imperfect, therefore, simply by mental speculation it is not possible to realize God. Then how one can realize God? That is mentioned in the Bhagavad-gītā and other literatures, that by the mercy of God one can realize God. So by His causeless mercy, He comes down. Yadā yadā hi dharmasya glānir bhavati bhārata (BG 4.7), it is stated in the Bhagavad-gītā.

Pandal Lecture at Cross Maidan -- Bombay, March 26, 1971:

This world is meant for duality. So it is called dvaita. Dvaita means duality. So Kṛṣṇa dāsa Kavirāja Gosvāmī, he says, dvaite bhadrābhadra sakali samāna, ei bhāla ei manda saba manodharma. In the world of dualities, bhadrābhadra, "This is good, this is bad, this is nice, this is not nice," they are simply mental speculation because in this world nothing is nice. Everything is bad because it is not eternal. Therefore Śaṅkarācārya said, jagan mithyā, brahma satya. That's a fact. These, anything, the varieties of this world: temporary. That is the right word. It is not mithyā; it is temporary fact.

Pandal Lecture at Cross Maidan -- Bombay, March 26, 1971:

This is Kṛṣṇa's business. Responsive cooperation. As you advance, as you try to serve Kṛṣṇa sincerely, sevonmukhe ji jihvādau svayam eva sphuraty adaḥ. We cannot realize Kṛṣṇa or God by mental speculation or by material advancement. We have to render service to Kṛṣṇa. Then Kṛṣṇa will be pleased and He will give you dictation from within how we can make advance in Kṛṣṇa consciousness. And that is the successful life of human form of existence.

Pandal Lecture -- Bombay, March 31, 1971:

Ladies and gentlemen, I thank you very much for your participating in this meeting, Kṛṣṇa consciousness movement. This Kṛṣṇa consciousness movement is very much authorized. It is nothing like concocted mental speculation. It is authorized on the basis of Vedic knowledge, specifically, directly from the Supreme Personality of Godhead, Lord Kṛṣṇa, five thousand years ago when there was no history of other religion. In the modern age, any religion you can take into consideration, they are not older than 2,600 years. But so far this Bhagavad-gītā is concerned, it was spoken in the Battlefield of Kurukṣetra five thousand years ago.

Pandal Lecture -- Bombay, March 31, 1971:

Bhagavat-tattva-vijñānam. It is a science. It is not a mental speculation or whimsical theorizing, that "God may be like this, God may be like that," and different philosophers will differ from one another. It is not like that. It is a great science. As two plus two equal to four, nobody can make it "Two plus two equal to five" or "Two plus two equal to three." Anywhere, science is science, fact. Similarly, Bhagavad-gītā you cannot interpret differently. Just like "Two plus two equal to five"—that cannot be. You have to accept "Two plus two equal to four."

Pandal Lecture -- Bombay, April 6, 1971:

So these four deficiencies of conditioned soul are there; therefore we cannot have perfect knowledge by our mental speculation. That is not possible. We have to receive knowledge from authorities. That is the process. Mahājano yena gataḥ sa panthāḥ (CC Madhya 17.186). If we receive knowledge... Our process is that we are trying to receive knowledge from Kṛṣṇa, the greatest mahājana, the greatest authority, and if we follow the instruction of Kṛṣṇa, then we are perfect.

Pandal Lecture -- Bombay, April 7, 1971:

After your mucus or any, all nasty things you throw away, the crows will come there. They will enjoy. Therefore Bhāgavata says, "Such literary productions where there is no glorification of the Supreme Lord, it is just like the enjoyable spot of the crows." But there is another class of birth who are called swans, rāja-haṁsa. They will not come there. They will not come there and enjoy with the crows. This is natural division. They will go in a place where there is very clear reservoir of water, nice trees, nice fruits and flowers, nice birds, mānasa-tīrthas, mānasa-gaṅgā, like that. They will enjoy there. Similarly, this mental speculation, huge, huge books, will be enjoyed by a class of men who are compared with the crows. But glorification of Kṛṣṇa will be enjoyed by a class of men who are called swans or paramahaṁsas.

Pandal Lecture -- Delhi, November 13, 1971:

Material life means sensuous life. But those who are little above, they are on the mental platform—poetry, philosophy, mental speculation. Above this there is intelligence. That intellectual life required. That means we have to transcend the position of the sensuous life, we have to transcend the position of concocted mental speculation, we have to come to the intellectual platform. That intellectual platform is called brahma-jijñāsā. Athāto brahma jijñāsā. Just like Sanātana Gosvāmī, when he approached Lord Caitanya, he very intellectually asked Lord Caitanya, 'ke āmi' kene more jāpe tāpa-traya: "Who am I? Why I am suffering these three kinds of material miserable condition of life?" This is intellectual platform. This is intellectual path. And when we exercise this intellectual path of our life, that is called buddhi-yogam. Buddhi-yogam. Therefore, in the Caitanya-caritāmṛta it is said, kṛṣṇa ye bhaje se baḍa catura. The most intellectual person can become Kṛṣṇa conscious, not ordinary man.

Lecture -- Bombay, March 18, 1972:

You cannot understand God, Kṛṣṇa, by your mental speculation. (coughs) That is called Kūpa-maṇḍūka-nyāya, Dr. Frog philosophy. A frog from within the well, he's trying to study Atlantic Ocean. This is a logic given in the Nyāya-śāstra. Kūpa-maṇḍūka-nyāya. What he'll study about the Atlantic Ocean? One who has got knowledge, three-feet knowledge in the well, what idea he'll get about Atlantic Ocean or Pacific Ocean? As it is not possible simply by imagination, simply, similarly, if you try to understand about God, or Kṛṣṇa, by your mental speculation, it will be simply a waste of time.

Lecture -- Bombay, March 18, 1972:

You have to understand God, or Kṛṣṇa, from Him. Sevonmukhe hi jihvādau (Brs. 1.2.234). Just like you cannot see the sun at this time, when the night is dark. You cannot, ah, I mean to say, invent some searchlight and ask people, "Please come on the roof. I shall show you the sun by the searchlight." It is not possible. By your endeavor you cannot see the sun at night. But when the sun rises in the morning, you can see. That is the process. Similarly, you cannot understand God by your mental speculation. You have to submit yourself.

Lecture at Art Gallery -- Auckland, April 16, 1972:

So this is being possible in the effulgence, brahma-jyotir, of Kṛṣṇa. Kṛṣṇa's bodily effulgence is called brahma-jyotir. It is stated in the Bhagavad-gītā, brāhmaṇaḥ ahaṁ pratiṣṭhā. The brahma-jyotir... Those who are jñānīs, those who are trying to approach the Absolute Truth by mental speculation, by dint of our teeny knowledge, they can, utmost, approach to this brahma-jyotir. But that brahma-jyotir is only emanation of the bodily effulgence of Kṛṣṇa. Yasya prabhā prabhavato (Bs. 5.40). Just like the light and the illumination is coming from the light, from that localized bulb, similarly, the brahma-jyotir is coming out. Just like the sunshine, the best example, the sunshine, illumination of the sunlight, sunshine, is coming from the sun planet. The sun planet is localized. We can see it. And the effulgence, and the bodily effulgence of the sun planet is distributed all over the universe.

Rotary Club Lecture -- Hyderabad, November 29, 1972:

So there are so many things, problems of our life; we are neglecting. And everything is very clearly described in the Bhagavad-gītā. It is being, explained by the Supreme Personality of Godhead Himself. We should take advantage of these lessons in the Bhagavad-gītā. Unfortunately, in the foreign countries, before me, many other swamis went, tried to explain Bhagavad-gītā. Bhagavad-gītā is very well known book of knowledge. In America and Europe and other countries there are many translations. But the Bhagavad-gītā, such translation is taken as a mental speculation.

Lecture -- Vrndavana, March 14, 1974:

We, our, this Kṛṣṇa consciousness movement is to understand the prabhu, who is prabhu, who is the master, who is the Supreme Absolute. This is Kṛṣṇa consciousness movement: to understand the supreme prabhu, or master, or controller, and surrender unto Him. This is the process, simple process. That prabhu you can under..., cannot understand by mental speculation. That is not possible. Nāyam ātmā pravacanena labhyo na bahunā śrutena. There are many Vedantists, many scholars in Vedic literature, but they do not know who is his prabhu. They will say, "prabhu," but I ask him, "Who is your prabhu?" That they cannot say.

Philosophy Discussions

Philosophy Discussion on Immanuel Kant:

Prabhupāda: This must be. One who goes with mental speculation, he must fail. Therefore our process is not mental speculation—to receive knowledge from the perfect.

Śyāmasundara: So he says that man tends to create ideas about the universe which transcend the bounds of experience, and this is what he calls the third stage, or the transcendental dialectic. He says these ideas which transcend the bounds of experience are the realm of pure reason. He calls it pure reason, or transcendental reason. And these are not fictions, but these spring from the very nature of reason itself, these transcendental ideas.

Prabhupāda: Yes. That I already explained: transcendental. We are seeking eternity. I find myself as a soul; I am eternal; so I must seek an eternal world. This is not my place. I am eternal. The same example: just like fish taken from the water, he is not finding comfortable life. So when the fish is thrown in the water, then it is comfortable. Similarly, I am spirit soul. I am not feeling comfortable with this material body.

Philosophy Discussion on Immanuel Kant:

Prabhupāda: Yes. That is called philosophy. That inquisitiveness is called philosophy. Cause of the cause: this is caused by this; what is the cause of this? Unless he comes to the final cause, this research goes on. That is the nature of advanced mind. They are called munis, those who are very thoughtful. So that is the nature of greater mind, mahātmā, to find out the ultimate cause. That is human nature. Therefore, athāto brahma jijñāsā. The Vedānta-sūtra says this jijñāsā, inquiry, "What is after this? What is after this? What is brāhmaṇas? What is Brahman? This is not Brahman. This is not Brahman..." The next answer is that "Brahman means janmādy asya (SB 1.1.1), the supreme source from where everything emanates." So unless he goes to the supreme source, he is not satisfied. So those who are going by mental speculation, they come to that impersonal feature.

Philosophy Discussion on Immanuel Kant:

Prabhupāda: No. Because suppose that a snake is here and it is dangerous; he'll bite. So killing is necessary. But if you say, "No. I shall not kill this snake. Let it bite. All right, let them all die..." These are simply mental speculations. He has no perfect knowledge.

Philosophy Discussion on Immanuel Kant:

Prabhupāda: Why not virtue? If you get happiness, that is virtuous. That means he has no standard knowledge. Harāv abhaktasya kuto mahad-guṇā (SB 5.18.12). If a man is not a devotee of Kṛṣṇa, he has no good qualities. He may be a great philosopher, scientist, but he is a nonsense. Harāv abhaktasya kuto mahad-guṇā, mano-rathenāsati dhāvato bahiḥ (SB 5.18.12). By his mental speculation he is coming again and again on this material platform, that's all. He has no idea what is happiness, what is goal of life, the aim of life. He has no such idea. Vague. So therefore imperfect knowledge.

Philosophy Discussion on Hegel:

Prabhupāda: That we say, that religion without philosophy is sentiment and philosophy without religion is mental speculation.

Śyāmasundara: But he wants to have philosophy without religion. He says that philosophy...

Prabhupāda: That is mental speculation. He says that above religion is philosophy. That means religion supported by philosophy is real religion. Religion supported by philosophy is real religion. Otherwise insufficient. It is same thing. That's all. Actually except Bhāgavata religion, all other religions in the world are sentiments. Therefore in Bhāgavata beginning is said, dharmaḥ projjhita kaitava, all cheating type of religion is kicked out from dharma. Projjhita, kicked out. Except Bhāgavata religion, any religion which is going on in the world, they're all cheating.

Philosophy Discussion on Charles Darwin:

Prabhupāda: Even Dr. Radhakrishnan has said mental speculation is a big thing, of the Western propaganda.

Śyāmasundara: I think he said it is the crowning achievement of speculative thought.

Prabhupāda: He has said like that?

Śyāmasundara: "Bhagavad-gītā is the crowning achievement of speculative thought," as if some sages thought it up.

Prabhupāda: Now what is there? Finished. (break) ...fact. It is known to the Vedic culture millions of years ago. (indistinct) I was reading, aśitiṁ caturaś caiva, this is Brahmā-vaivarta Purāṇa and this Brahmā-vaivarta Purāṇa was written by Vyāsadeva five thousand years ago. And it was known long, long years ago. It was written in the Purāṇas, but it was coming by tradition long, long ago. So (indistinct). He has stolen this theory, this idea, from Brahmā-vaivarta Purāṇa, and he has tried to prove it in a different way. Otherwise this evolutionary theory is already there.

Philosophy Discussion on Charles Darwin:

Prabhupāda: That's all. It is simply mental speculation.

Śyāmasundara: They haven't even come near to these things yet.

Prabhupāda: They'll never come.

Philosophy Discussion on William James:

Prabhupāda: So philosophy without practical application is called mental speculation. It has no value. We agree to that. Philosophy must be practically applied in life. That is real philosophy.

Philosophy Discussion on William James:

Prabhupāda: Philosophy without any fact is mental speculation. What is the value of such philosophy? He has already practical value. According to person, your mentality, your personality may not agree with me. Then you have got different philosophy. And what is the practical use?

Devotee: This seems to have a similarity to the divisions of faith according to the three guṇas.

Prabhupāda: No. The philosophy is not faith. Faith is a different thing, and fact is different thing. Philosophy must be on the fact, not on faith. Faith may be blind faith. That is different thing.

Philosophy Discussion on Soren Aabye Kierkegaard:

Śyāmasundara: Yes. He says that then they indulge in pleasure and mental speculation as a diversionary tactic. To try to cover up this despair, they become more indulged in sense pleasure and more speculating.

Prabhupāda: Just like people in the material world, when a businessman failure, he takes to drinking. Sometimes great shock, in order to forget, one takes to drinking. Yes. Intoxication.

Philosophy Discussion on Soren Aabye Kierkegaard:

Śyāmasundara: This may be likened to the people who do pious works, or the people who do good to others, who are morally committed to life, on that level. To feed others, clothe others, like that. They say that that is a step higher than simply sense gratification and speculation. He says that "This is a move in the right direction toward authentic selfhood, and eventually this way we will understand what I am. And because we are at last doing something, we are involved with life, then we are no more abstract. We are existing." Then we are existing. That someone who is doing all sense gratification and mental speculation, they are living abstract life, abstract life, external life. Simply waiting for the enjoyment of life and speculating what is the meaning of things, that is abstract life, and this being committed to action or decision-making is called existence. This is the first step toward real existence. So in this ethical stage he says that by the very act of making decisions that we become aware, that we become more and more aware, and that decision-making means awareness. And if we make choices about anything, that means that we are becoming aware.

Prabhupāda: What is the decision? Why people become moral—to feed the poor, like that, humanitarian? What is the decision, ultimate decision?

Śyāmasundara: He says that it's not so much the fact of the decision but how the decision is made: if it's made with integrity and self-confidence.

Prabhupāda: How the decision... Why, how the decision is made, that I still don't know. How? Why? Why they make such decision? One man is running on a slaughterhouse. He's killing only. Another man is after humanitarian work, giving food, giving them chance to live. So what is the ultimate decision?

Philosophy Discussion on Soren Aabye Kierkegaard:

Prabhupāda: Because it's simply mental speculation. There is no basis.

Śyāmasundara: The Christian monks, ascetics, they always thought that the life they were giving up, they were suffering, always that feeling...

Prabhupāda: Poor fund of knowledge, that's all.

Philosophy Discussion on Edmund Husserl:

Prabhupāda: On the whole, his process is mental speculation.

Śyāmasundara: So he says that in things there is a self-evident truth. In everything there is something self-evident that makes it true. Is that not possible?

Prabhupāda: That self-evidence is certain (indistinct). Just like this leaf, that you see the greenness of the leaf, but that is not all. If you actually want to study that leaf, simply the superficial vision of the leaf as green is not all.

Philosophy Discussion on Carl Gustav Jung:

Prabhupāda: No, it is not religion. It is simply mental speculation—how to adjust material things. It will never be able to adjust it. That is their simply imagination. It will all fail at the ultimate end.

Philosophy Discussion on Bertrand Russell:

Prabhupāda: No. No emotion. We don't... Just like Arjuna. By emotion he was thinking, "I shall not fight." That was emotion. So "I shall be bad man, taking to these orders"—these are... Anything material, that is emotion, sentiment. Yes. So religion without philosophy is sentiment, and philosophy without religion is mental speculation. So therefore our this Kṛṣṇa consciousness movement is so sound. We do not go by sentiment. We accept the superior order of Kṛṣṇa (indistinct), it is perfect.

Philosophy Discussion on Mao Tse Tung:

Prabhupāda: Well, that conflict is no use. Social... So far the modern society is concerned, it is based on mental speculation. There is no standard. Some society has a different standard, another society has a different standard. But none of them are based on some authority. Therefore such conflict cannot bring you into some right conflict if both of them are wrong. The so-called capitalist and so-called communist, they are all on the wrong basis. So by such conflict you cannot come to a recognized standard.

Philosophy Discussion on Mao Tse Tung:

Prabhupāda: Yes. So this is going on. That is not Mao is a very perfect man, his theory is perfect, he is better than... It is simply mental speculation.

Śyāmasundara: But he examines his theory, and he sees that the nature of his theory or the nature of things is this conflict. This is the nature of things.

Prabhupāda: That we have already talked; there is conflict. Conflict is going on.

Philosophy Discussion on Socrates:

Hayagrīva: ...that Śyāmasundara treated, but they're somewhat incomplete, so I will read. I've gone to the primary sources. He used a college outline series that wasn't really adequate. So I went to the primary sources, and I'll read a little, and if you want to comment on it, comment. If you don't feel like commenting on it, I'll just go on to the next section.

Once a student of Socrates—this is a section on Socrates-said, "I cannot refute you, Socrates." To this Socrates replied, "Say rather that you cannot refute the truth, for Socrates is easily refuted." This is by way of saying that the Absolute Truth is not a subject of mental speculation or personal opinion. The Truth, or the good, for Socrates stands separate from mundane relativities or personal opinion.

Prabhupāda: That is our opinion. We accept Kṛṣṇa as the supreme authority, and therefore we cannot refute what Kṛṣṇa says. And our philosophy is perfect because we follow Kṛṣṇa. He is the Supreme Perfect. This is our position. In other religious system, taking it our Kṛṣṇa consciousness movement religious... It is religious, because our religion means the..., to carry out the order of God. That is the sum and substance of religion. We don't manufacture religion, and neither religion can be manufactured. Manufactured religion is useless. That has been described in the Bhagavad-gītā, er, Śrīmad-Bhāgavatam as dharma kaitava. Means cheating. So this is not cheating religion. Our basic principle is dharmaṁ tu sākṣād bhagavat-praṇītam (SB 6.3.19). Dharma means the order which is given by God, and if you execute that, that is dharma. Just like law. Law is given by the government. You cannot manufacture law. That is not law. So our perfection is there, how we are executing the order of God cent percent. One who has no conception of God, neither the order of God, they can manufacture religious system. But our system is different.

Philosophy Discussion on Socrates:

Prabhupāda: So they are not philosopher; they are Christian with different point of views. So we are not going to discuss with a person he is from the stand..., deviating from the standard way and thinking in their mental speculation.

Philosophy Discussion on Plotinus:

Hayagrīva: Plotinus saw the individual souls returning to God or the One through three stages. The first stage is that of asceticism, detaching oneself from the material world. The second stage, one detaches oneself from the process of reasoning itself. That would be mental speculation. And in the third stage the intellect transcends itself into the realm of the unknown, the realm of the One, and he speaks of this as an ecstasy, an involvement, or a transcendence of the ego. So these are the three stages of God realization that he sets down.

Prabhupāda: That means, what he called three stages, karmī, jñānī, yogi. That karmīs, they are trying to improve their condition by this material science and material advancement of education, and some of them are trying to go the heavenly planets by pious activities. These are karmīs. And higher than the karmīs are the jñānīs. They are speculating on the Absolute Truth by their education and coming to the conclusion that God is impersonal; when we merge into that impersonal feature, that is our liberation. And the yogis, they are trying to get some mystic power by practicing mystic yoga system—wonderful power, aṣṭa-siddhi, eight kinds of perfection: to become lighter than the lightest, to become smaller than the smallest, to become bigger than the biggest. Whatever they like, they can get. They can subdue anyone, bring under his control with that yogic (indistinct). But real yoga means to see the Supreme within the core of the heart. Dhyānāvasthita-tad-gatena manasā paśyanti yaṁ yoginaḥ (SB 12.13.1). In this way there are different processes. They are called karma, jñāna and yoga. But they require endeavor to elevate, strenuous endeavor, all these practices. But the, the supreme process is simply to surrender unto the Supreme One, and He gives out intelligence how to be free from this material entanglement, and that is called bhakti-yoga. It is very pleasing to execute, and without any, much endeavor. Simply being fully surrendered to the Supreme Lord, he immediately becomes purified from all material contamination, and little practice of bhakti-yoga makes him completely fit for going back to home, back to Godhead.

Philosophy Discussion on Rene Descartes:

Hayagrīva: Descartes, Rene Descartes, the French... Descartes writes, "The power of forming a good judgment and of distinguishing the true from the false, which is, properly speaking, what is called good sense or reason, is by nature equal in all men. God has given to each of us some light with which to distinguish truth from error." Now in the West this has been called conscience, and Descartes uses the term "reason." Now is this simply a form of mental speculation, or is the...

Prabhupāda: No. Mental speculation should be there. It is not actually speculation but it is reasoning. Just like if we study our own body, whether I am this lump of matter, namely this skin, bone and stool, urine and muscle and blood... If we analyze this body we find practically these things. So the reasoning is that whether combination of these things can give life. So externally we have got all these things. Blood we can get from slaughterhouse, and bone we can collect, or you can manufacture and set up an instrument with these things. Will it be, bring life? So the reasoning is life is different from this lump of matter. That is reasoning.

Philosophy Discussion on B. F. Skinner and Henry David Thoreau:

Prabhupāda: That is primitive life, jungle life. Monkey civilization. Of course they claim to be descendant of monkey, that they will go on like that. But that is not human civilization, to keep the monkey in the jungle. We want life, very peaceful life without any unnecessary, what is called, necessities. That is all right. But the aim should be spiritual perfection. Therefore the first thing is what is the aim of life, that should be ascertained. Without aim, if you lounge on this ocean, where you are going? That is useless attempt. We must first of all know what is the aim of life. These people, they do not know what is the aim of life. Simply, superficially they are trying to adjust, "This will be done, this will be done." No. These are all mental speculation. First of all you must know what is the aim of life, and to this, to that direction, we have to adjust things. That is perfection.

Purports to Songs

Purport to Parama Koruna -- Atlanta, February 28, 1975:

Because everyone is fool, but they are divided by mental concoction that "Here is a fool; here is a learned." Because the learned is also a fool. But by mental concoction, he is recognized as intelligent. Same mental concoction. Dvaite' bhadrābhadra sakali samana. Caitanya-caritāmṛta kar said that "In the material world, this is good; and this is bad—this is all mental speculation." Dvaite' bhadrābhadra sakali samana, ei bhāla, ei manda', saba manodharma: "That division, 'This is good; this is bad,' it is mental speculation." It has no value. It has no value. So this mental speculation will not help us. And therefore sthāne sthitāḥ. You remain in your position. It doesn't matter, good or bad. The mental speculator's verdict that "This is good; this is bad. This is intelligent; this is fool," they are all mental speculation. That will not help.
