CC Adi-lila

CC Adi 3.111, Purport:

One cannot speak of Urugāya (the Lord, who is glorified by sublime prayers) unless one is transcendentally elevated.

CC Adi 4.29, Purport:

The erotic principles of amorous love reflected in mixed material values are perverted reflections of the reality of spirit, but one cannot understand the reality unless one is sufficiently educated in the spiritual science.

CC Adi 4.34, Purport:

In other words, unless one is trained under the disciplic succession of the Gosvāmīs, one cannot understand Rādhā and Kṛṣṇa.

CC Adi 5.204, Purport:

Śrīla Narottama dāsa Ṭhākura, who is famous for his poetic composition known as Prārthanā, has lamented in one of his prayers, "When will Lord Nityānanda be merciful upon me so that I will forget all material desires?" Śrīla Narottama dāsa Ṭhākura confirms that unless one is freed from material desires to satisfy the needs of the body and senses, one cannot understand the transcendental abode of Lord Kṛṣṇa, Vṛndāvana.

CC Adi 6 Summary:

When He is addressed as the servitor of Lord Caitanya, His glories are magnified because unless one is invigorated by this mentality of servitorship one cannot understand the mellows derived from devotional service to the Supreme Lord, Kṛṣṇa.

CC Adi 7.64, Purport:

They are always under the impression that unless one is a brāhmaṇa and a very good Sanskrit scholar, especially in grammar, one cannot accept the renounced order of life or become a preacher.

CC Adi 7.67, Purport:

Thus in our Kṛṣṇa consciousness movement we never offer the sannyāsa order to a person whom we do not find to be qualified in terms of the prescribed brahminical principles. Although it is a fact that unless one is a brāhmaṇa he cannot become a sannyāsī, it is not a valid principle that an unqualified man who is born in a brāhmaṇa family is a brāhmaṇa whereas a brahminically qualified person born in a non-brāhmaṇa family cannot be accepted.

CC Adi 7.105, Purport:

Unless one is spiritually advanced he cannot influence an audience. Bhaktivinoda Ṭhākura has sung, śuddha-bhakata-caraṇa-reṇu, bhajana-anukūla. "Unless one associates with a pure devotee, he cannot be influenced to understand devotional service."

CC Adi 8.16, Purport:

One cannot reach this conclusion unless one is offenseless in chanting the holy name. By our material calculation we see a difference between the name and the substance, but in the spiritual world the Absolute is always absolute: the name, form, qualities and pastimes of the Absolute are all as good as the Absolute Himself.

CC Adi 8.17, Purport:

It is the statement of Prahlāda Mahārāja that unless one is able to accept the dust from the lotus feet of a pure Vaiṣṇava there is no possibility of achieving the platform of devotional service. That is the secret.

CC Adi 8.24, Purport:

It is said in the śāstra (CC Antya 7.11), kṛṣṇa-śakti vinā nahe tāra pravartana: one cannot distribute the holy names of the Hare Kṛṣṇa mahā-mantra unless he is empowered by the Supreme Personality of Godhead. Therefore one should not criticize or blaspheme a devotee who is thus engaged.

CC Adi 8.26, Purport:

One cannot be situated in the devotional service of the Lord unless one is free from sinful life. This is confirmed in the Bhagavad-gītā (7.28):

yeṣāṁ tv anta-gataṁ pāpaṁ janānāṁ puṇya-karmanām

te dvandva-moha-nirmuktā bhajante māṁ dṛḍha-vratāḥ

"Persons who have acted piously in previous lives and in this life and whose sinful actions are completely eradicated are freed from the duality of delusion, and they engage themselves in My service with determination."

CC Adi 8.31, Purport:

Unless one is favored by Lord Caitanya and Nityānanda, there is no need to go to Vṛndāvana, for unless one's mind is purified, he cannot see Vṛndāvana, even if he goes there.

CC Adi 8.31, Purport:

Unless one is very fortunate, he should not be induced to worship Rādhā-Kṛṣṇa directly. A neophyte student who is not sufficiently educated or enlightened should not indulge in the worship of Śrī Rādhā and Kṛṣṇa or the chanting of the Hare Kṛṣṇa mantra. Even if he does so, he cannot get the desired result.

CC Adi 8.72, Purport:

Unless one is empowered by the higher authorities, or advanced devotees, one cannot write transcendental literature, for all such literature must be above suspicion, or, in other words, it must have none of the defects of conditioned souls, namely mistakes, illusions, cheating and imperfect sense perceptions.

CC Adi 9.4, Purport:

Unless one is a servant of Kṛṣṇa and the Vaiṣṇavas, as Kṛṣṇadāsa Kavirāja Gosvāmī presents himself to be in offering respects to Lord Caitanya, His associates and His disciples, one should not attempt to write transcendental literature.

CC Adi 9.42, Purport:

However, unless one is interested in śreyas in his own life, he cannot preach of śreyas for the benefit of others.

CC Adi 9.51, Purport:

Unless one is able to understand the philosophy that he speaks, it will not be effective. Therefore one should not only understand the philosophy of the Caitanya cult but also implement it practically in one's life.

CC Adi 16.50, Purport:

Unless one is a medical man he cannot criticize a medical man, and unless one is a lawyer he cannot criticize a lawyer. Therefore Keśava Kāśmīrī first depreciated the Lord's position. Because Śrī Caitanya Mahāprabhu was to the champion a student of grammar, how could He dare criticize a great poet like him? Lord Caitanya, therefore, criticized the poet in a different way.

CC Madhya-lila

CC Madhya 4.87, Purport:

This example given by Mādhavendra Purī confirms that even though a brāhmaṇa may be very expert, he cannot become a priest or servitor of the viṣṇu-mūrti unless he is initiated in vaiṣṇava-mantra. After installing the Deity of Gopāla, Mādhavendra Purī initiated all the brāhmaṇas into Vaiṣṇavism.

CC Madhya 4.111, Purport:

In other words, unless one is a brāhmaṇa, he cannot make another a brāhmaṇa. A gṛhastha-brāhmaṇa partaking of the varṇāśrama-dharma institution can secure various types of paraphernalia to worship Lord Viṣṇu through his honest labor. Actually, people beg to be initiated by these householder brāhmaṇas just to become successful in the varṇāśrama institution or to become free from material desires.

CC Madhya 6.151, Purport:

Unless one is favored by a devotee, he cannot understand the Supreme Personality of Godhead. Arjuna also confirms this in the Bhagavad-gītā (10.14): "My Lord, it is very difficult to understand Your personality." The less intelligent class of men cannot understand the Supreme Personality of Godhead without being favored by His devotee.

CC Madhya 8.44, Purport:

Unless one is a first-class devotee, he cannot be a preacher. A preacher is generally a topmost devotee, but in order to meet the general populace, he has to come to distinguish between devotees and nondevotees. Otherwise, an advanced devotee makes no such distinctions. Indeed, he always sees that everyone is engaged in the service of the Lord.

CC Madhya 8.128, Purport:

However, even if a vipra, or brāhmaṇa, is very expert in the six brahminical activities (paṭhana, pāṭhana, yajana, yājana, dāna, pratigraha) and is also well versed in the Vedic hymns, he cannot become a spiritual master unless he is a Vaiṣṇava. But if one is born in the family of caṇḍālas yet is well versed in Kṛṣṇa consciousness, he can become a guru.

CC Madhya 8.128, Purport:

Unfortunately, those who are unintelligent do not know the difference between a brāhmaṇa and a Vaiṣṇava. They are under the impression that unless one is a brāhmaṇa he cannot be a spiritual master.

CC Madhya 8.139, Purport:

One cannot compare the lusty desires of a materialistic man to the transcendental lusty desires of Kṛṣṇa. Unless one is advanced in spiritual science, he cannot understand the lusty desires between Kṛṣṇa and the gopīs. In the Caitanya-caritāmṛta the lusty desire of the gopīs is compared to gold.

CC Madhya 8.250, Purport:

Unless one is a devotee, it is very dangerous to hear the songs about the pastimes of Rādhā and Kṛṣṇa that were written by Jayadeva Gosvāmī, Caṇḍīdāsa and other exalted devotees. Lord Śiva drank an ocean of poison, but one should not imitate this.

CC Madhya 8.255, Purport:

Unless one is liberated, he should not try to hear about the loving affairs between Rādhā and Kṛṣṇa. If one is not liberated and listens to a relation of the rāsa dance, he may remember his own mundane activities and illicit connections with some woman whose name may also be Rādhā.

CC Madhya 9.61, Purport:

Unless one is favored by Śrī Caitanya Mahāprabhu in the disciplic succession, one cannot act as a spiritual master. We should take the instructions of Śrī Caitanya Mahāprabhu, the spiritual master of the whole universe, to understand how one becomes a spiritual master and a disciple.

CC Madhya 9.155, Purport:

Unless one is instructed by a bona fide spiritual master, he cannot perfectly understand these different forms. The Brahma-saṁhitā confirms, vedeṣu durlabham adurlabham ātma-bhaktau (Bs. 5.33).

CC Madhya 9.258, Purport:

In the material world, unless one is situated in one of the varṇas (brāhmaṇa, kṣatriya, vaiśya or śūdra) one cannot manage social affairs properly to attain the ultimate goal.

CC Madhya 9.289, Purport:

Unless one is connected to the disciplic succession of Mādhavendra Purī, there is no possibility of awakening the symptoms of ecstatic love. The word gosāñi is significant in this connection.

CC Madhya 9.289, Purport:

The senses cannot be controlled unless one is engaged in the service of the Lord; therefore the bona fide spiritual master, who has full control over his senses, engages twenty-four hours a day in the Lord's service.

CC Madhya 10.65, Purport:

Only one who is overwhelmed by māyā can be so unfortunate as to leave Śrī Caitanya Mahāprabhu's company, yet unless one is very conscientious, the influence of māyā can drag one away, even though he be the personal assistant of Śrī Caitanya Mahāprabhu.

CC Madhya 11.192, Purport:

Unless one is spiritually advanced, he cannot be called an Āryan, and this is the difference between Āryan and non-Āryan. Non-Āryans are those who are not spiritually advanced. By following the Vedic culture, by performing great sacrifices and by becoming a strict follower of the Vedic instructions, one may become a brāhmaṇa, a sannyāsī or an Āryan.

CC Madhya 13.67, Purport:

The King could see Śrī Caitanya Mahāprabhu simultaneously present in all seven groups. As confirmed in Śrīmad-Bhāgavatam, one cannot see the expansions of the transcendental forms of the Lord unless one is a pure devotee of the Lord.

CC Madhya 15.108, Purport:

Unless one is initiated as a brāhmaṇa, one cannot worship the holy name properly.”

CC Madhya 15.108, Purport:

""Unless one is initiated by a bona fide spiritual master, all his devotional activities are useless. A person who is not properly initiated can descend again into the animal species.""

CC Madhya 15.169, Purport:

Unless one is freed from sinful life, one cannot become a Vaiṣṇava. In other words, if one is a Vaiṣṇava, his sinful life is certainly ended.

CC Madhya 15.277, Purport:

This means that he is not yet liberated, for liberation cannot be attained unless one is completely free from the modes. In any case, the Māyāvāda philosophy keeps one conditioned. If one becomes a Vaiṣṇava through proper initiation, he automatically becomes a brāhmaṇa. There is no doubt about it.

CC Madhya 15.277, Purport:

Unless one is a fully qualified brāhmaṇa, he cannot advance in the spiritual science. A real brāhmaṇa is never envious of Vaiṣṇavas. If he is, he is considered an imperfect neophyte. Impersonalist brāhmaṇas are always opposed to Vaiṣṇava principles.

CC Madhya 17.14, Purport:

Māyā is so strong that unless one is determined not to fall victim, even the Supreme Personality of Godhead cannot give protection. The Supreme Lord and His representative always want to give protection, but a person must take advantage of their personal contact.

CC Madhya 18.99, Purport:

Unless one is enlightened by the knowledge given by the spiritual master, he cannot see things as they are, even though he remains constantly with the spiritual master. This incident at Kālīya-daha is very instructive for those eager to advance in Kṛṣṇa consciousness.

CC Madhya 19.50, Translation:

“(Lord Kṛṣṇa said:) ‘Even though a person is a very learned scholar of the Sanskrit Vedic literatures, he is not accepted as My devotee unless he is pure in devotional service. Even though a person is born in a family of dog-eaters, he is very dear to Me if he is a pure devotee who has no motive to enjoy fruitive activities or mental speculation. Indeed, all respects should be given to him, and whatever he offers should be accepted. Such devotees are as worshipable as I am.”’

CC Madhya 19.135, Purport:

Unless one is specifically empowered by the Supreme Personality of Godhead, he cannot spread the Kṛṣṇa consciousness movement. An empowered devotee sees and feels himself to be the lowest of men, for he knows that whatever he does is due to the inspiration given by the Lord in the heart.

CC Madhya 20.58, Translation:

“(Lord Kṛṣṇa said:) "Even though a person is a very learned scholar of the Sanskrit Vedic literatures, he is not accepted as My devotee unless he is pure in devotional service. However, even though a person is born in a family of dog-eaters, he is very dear to Me if he is a pure devotee who has no motive to enjoy fruitive activity or mental speculation. Indeed, all respects should be given to him, and whatever he offers should be accepted. Such devotees are as worshipable as I am."

CC Madhya 20.130, Purport:

Everyone is trying to adjust to the distressed conditions of material existence, but the basic problems cannot be solved unless one is in an intimate relationship with Kṛṣṇa.

CC Madhya 21.18, Purport:

Unless one is freed from the reactions of sinful activities, one cannot understand Kṛṣṇa or engage in His transcendental loving service.

CC Madhya 22.51, Translation:

“Unless one is favored by a pure devotee, one cannot attain the platform of devotional service. To say nothing of kṛṣṇa-bhakti, one cannot even be relieved from the bondage of material existence.

CC Madhya 22.118, Purport:

Unless he is very powerful, he cannot assimilate all the sinful reactions of his disciples and has to suffer the consequences. Therefore one is generally forbidden to accept many disciples.

CC Madhya 22.142, Purport:

Due to our association with the modes of material nature, we get different types of bodies, good and bad. One cannot be liberated from the cycle of birth and death, known as transmigration of the soul, unless one is completely freed from all sinful activities.

CC Madhya 23.105, Purport:

According to the smārta process, one cannot be accepted as a brāhmaṇa unless he is born in a brāhmaṇa family. According to the gosvāmī process, the Hari-bhakti-vilāsa and the Nārada-pañcarātra, anyone can be a brāhmaṇa if he is properly initiated by a bona fide spiritual master.

CC Madhya 24.92, Translation:

“The other processes cannot yield results unless they are associated with devotional service. Devotional service, however, is so strong and independent that it can give one all the desired results.

CC Madhya 24.172, Translation:

“"Devotional perfection is very difficult to attain for two reasons. First, unless one is attached to Kṛṣṇa, he cannot attain devotional perfection even if he renders devotional service for a long time. Second, Kṛṣṇa does not easily deliver perfection in devotional service."

CC Madhya 24.323, Purport:

One can understand Śrīmad-Bhāgavatam only by following in the footsteps of Śrī Caitanya Mahāprabhu, who was mad for Kṛṣṇa. We cannot, of course, imitate Śrī Caitanya Mahāprabhu. It is not possible. However, unless one is very serious about understanding Kṛṣṇa, he cannot understand Śrīmad-Bhāgavatam. Śrīmad-Bhāgavatam gives the full narration of Kṛṣṇa's transcendental activities.

CC Madhya 24.326, Purport:

Unless one is fully qualified in Vaiṣṇava behavior and authorized by superior authority (the Supreme Personality of Godhead), one cannot write Vaiṣṇava literatures or purports and commentaries on Śrīmad-Bhāgavatam and the Bhagavad-gītā.

CC Madhya 24.330, Purport:

Unless one is qualified with all these attributes, he cannot be accepted as a brāhmaṇa. It is not a question of simply taking birth in a brāhmaṇa family. In this regard, Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura remarks that Narottama dāsa Ṭhākura and Śyāmānanda Gosvāmī, although not born in brāhmaṇa families, are accepted as bona fide spiritual masters because they were brāhmaṇas by qualification.

CC Madhya 24.330, Purport:

Only such a person is eligible to occupy the post of a guru. However, if one is highly qualified but is not a Vaiṣṇava, he cannot be accepted as a guru. One cannot be a brāhmaṇa unless one is a Vaiṣṇava. If one is a Vaiṣṇava, he is already a brāhmaṇa. If a guru is completely qualified as a Vaiṣṇava, he must be accepted as a brāhmaṇa even if he is not born in a brāhmaṇa family.

CC Madhya 24.331, Purport:

Unless one is fit according to the estimation of the spiritual master, one cannot accept a mantra from the pāñcarātrika-vidhi or the vaidika-vidhi. When one is fit to accept the mantra, one is initiated by the pāñcarātrika-vidhi or the vaidika-vidhi. In any case, the result is the same.

CC Madhya 25.42, Purport:

Unless one is free from the sin of animal-killing, he cannot understand religion or God. Although Lord Buddha was an incarnation of Kṛṣṇa, he did not speak about God, for the people were unable to understand. He simply wanted to stop animal-killing.

CC Antya-lila

CC Antya 1.211, Purport:

Unless one is a fully unalloyed devotee of the Lord, one should not try to describe the pastimes of Kṛṣṇa in poetry, for it will be only mundane.

CC Antya 2.14, Purport:

Unless one is empowered by the Supreme Personality of Godhead, Śrī Caitanya Mahāprabhu, one cannot spread the holy names of the Hare Kṛṣṇa mahā-mantra throughout the world. Persons who do so are empowered.

CC Antya 5.26, Purport:

Unless one is fully situated in the spiritual atmosphere, the activities of Rāmānanda Rāya are most difficult to understand.

CC Antya 5.85, Purport:

These highly exalted brāhmaṇas think that unless one is born in a brāhmaṇa family, one cannot become a spiritual master and teach the Absolute Truth.

CC Antya 7.12, Purport:

Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura explains that unless one is directly empowered by the causeless mercy of Kṛṣṇa, one cannot become the spiritual master of the entire world (jagad-guru).

CC Antya 14.37, Purport:

Unless one is a very highly advanced devotee, he cannot understand these intricate feelings. The author of Śrī Caitanya-caritāmṛta, however, has tried to explain this divyonmāda as far as possible, and it is our duty simply to appreciate it as far as possible.

Teachings of Lord Caitanya

Teachings of Lord Caitanya, Chapter 1:

Unless one is so situated, his position may not be steady and he may fall down. When one is actually situated transcendentally, there is no fear of falling down. This stage of understanding is technically called sthāyi-bhāva.

Teachings of Lord Caitanya, Chapter 1:

It is also stated in Bhakti-rasāmṛta-sindhu that one who understands this, whose intelligence is fixed on Kṛṣṇa, has attained the platform of śama. Moreover, the Supreme Personality of Godhead says: śamo manniṣṭhatā buddheḥ: Unless one is elevated to the platform of śānta-rati, he cannot be fixed in knowledge of the greatness of Kṛṣṇa or of the diffusion of His different energies, which are the cause of all manifestations.

Teachings of Lord Caitanya, Chapter 14:

Unless one is blessed by the spiritual master, or the ācārya, such teachings cannot become fully manifest. Therefore one should seek the mercy of the spiritual master so that the instructions of the spiritual master can develop within oneself. After receiving the prayers of Sanātana Gosvāmī, Lord Caitanya placed His feet on the head of Sanātana and gave him His benedictions so that all His instructions would develop fully.

Teachings of Lord Caitanya, Chapter 17:

Unless one is situated in uncontaminated goodness, it is very difficult to understand Lord Caitanya as the Supreme Personality of Godhead Himself. Thus in order to understand Lord Caitanya, one has to follow the direct disciples of Lord Caitanya—the six Gosvāmīs—and especially the path chalked out by Śrīla Jīva Gosvāmī.

Teachings of Lord Caitanya, Chapter 18:

A student is to be considered perfected when he understands the identity of the holy name and the Supreme Lord. Unless one is under the shelter of a realized spiritual master, his understanding of the Supreme is simply foolishness.

Teachings of Lord Caitanya, Chapter 22:

However, one cannot touch the lotus feet of the Supreme Lord unless one receives the benediction of the dust of the lotus feet of the Lord's pure devotee. In other words, one cannot become a pure devotee of the Supreme Personality of Godhead unless he is favored by another pure devotee of the Lord.

Teachings of Lord Caitanya, Chapter 23:

Unless one is freed from the influence of material energy, he cannot understand the Supreme Lord and His different energies. Nor can one who is captivated by the spell of material energy understand the spiritual form of the Supreme Lord.

Teachings of Lord Caitanya, Chapter 23:

Unless one is thoroughly accomplished in the transcendental knowledge of the Lord, he is sure to misunderstand the Lord's worshipable transcendental pastimes in the rāsa dance and the Lord's love affairs with the gopīs. This subject matter is highly spiritual and technical, and only liberated personalities who have gradually attained the stage of paramahaṁsa can transcendentally relish the worshipable rāsa dance.

Teachings of Lord Caitanya, Chapter 28:

Because it is still on the mental plane, it is external. The pure living entity is not liberated unless he is completely engaged in spiritual activity. As long as one is absorbed in impersonal thoughts or in thoughts of the void, his entrance into an eternal blissful life of knowledge is not completed.

Teachings of Lord Caitanya, Chapter 31:

There are many injunctions in the Padma Purāṇa which state that a highly elevated spiritually advanced devotee of the Lord is always a first-class devotee and is therefore a spiritual master, but a highly elevated person born in a brāhmaṇa family cannot be a spiritual master unless he is a devotee of the Lord.

Teachings of Lord Caitanya, Chapter 31:

This exchange of feelings between Kṛṣṇa and Rādhārāṇī is very difficult to understand unless one is elevated to the platform of pure goodness. Such transcendental reciprocation is not even possible to understand from the platform of material goodness.

Nectar of Devotion

Nectar of Devotion 1:

The priestly caste in charge of performing these ritualistic ceremonies recommended in the Vedas is called the brāhmaṇa order. Unless one is a brāhmaṇa, he cannot perform these ceremonies.

Nectar of Devotion 1:

So medical treatment may give temporary relief from the distress of such venereal disease, but unless one is trained to understand that sex life is abominable, it is impossible to be saved from such repeated distress. Similarly, the ritualistic performances, charity and austerity which are recommended in the Vedas may temporarily stop one from acting in sinful ways, but as long as the heart is not clear, one will have to repeat sinful activities again and again.

Nectar of Devotion 4:

Because they have no idea of the transcendental form of the Supreme Lord, there is no chance of their chanting and hearing of His transcendental activities. In other words, unless one is already beyond liberation, one cannot relish the transcendental glories of the Lord, nor can one understand the transcendental form of the Lord.

Nectar of Devotion 14:

Let the palatable dishes be prepared, but unless they are offered to Kṛṣṇa one should not accept them for eating. This vow of rejecting anything which is not offered to Kṛṣṇa is actually renunciation. And by such renunciation one is able to satisfy the demands of the senses.

Nectar of Devotion 15:

Unless one is fully situated in the transcendental position, the relationship of the gopīs with Kṛṣṇa is very difficult to understand. But because it appears to be just like ordinary dealings of young boys and girls, it is sometimes misinterpreted to be like the ordinary sex of this material world.

Nectar of Devotion 16:

We must always remember, however, that such eagerness to follow in the footsteps of the denizens of Vraja (Vṛndāvana) is not possible unless one is freed from material contamination. In following the regulative principles of devotional service, there is a stage called anartha-nivṛtti, which means the disappearance of all material contamination.

Nectar of Devotion 20:

Only by developing such faith in the association of a pure devotee, or by having in one's previous life executed devotional activities, can one actually relish the mellow of devotional service. In other words, this transcendental bliss is not to be enjoyed by any common man unless he is so extraordinarily fortunate as to be in association with devotees or to be continuing his previous birth's devotional activities.

Nectar of Devotion 40:

No one should claim his eternal relationship with Kṛṣṇa unless he is liberated. In the conditioned state of life, the devotees have to execute the prescribed duties as recommended in the codes of devotional service.

Nectar of Instruction

Nectar of Instruction 1, Purport:

When one accepts the renounced order of life, he automatically assumes the title of svāmī. This does not mean that he is the master of his family, community or society; he must be master of his senses. Unless one is master of his senses, he should not be called gosvāmī, but go-dāsa, servant of the senses.

Nectar of Instruction 4, Purport:

Unless one is very advanced, he is unable to utilize everyone's contribution to further the Kṛṣṇa consciousness movement; therefore on principle one should not accept charity from the Māyāvādīs or atheists. Indeed, Śrī Caitanya Mahāprabhu has forbidden devotees to associate even with ordinary men who are too addicted to material sense gratification.

Nectar of Instruction 6, Purport:

One should therefore not see a pure devotee from a materialistic point of view. Unless one is actually a devotee, he cannot see another devotee perfectly. As explained in the previous verse, there are three types of devotees—kaniṣṭha-adhikārī, madhyama-adhikārī and uttama-adhikārī. The kaniṣṭha-adhikārī cannot distinguish between a devotee and nondevotee.

Nectar of Instruction 6, Purport:

We very much regret their naive activities and poor fund of knowledge. An empowered person who is actually engaged in the confidential service of the Lord should not be treated as an ordinary human being, for it is stated that unless one is empowered by Kṛṣṇa, one cannot spread the Kṛṣṇa consciousness movement all over the world.

Krsna, The Supreme Personality of Godhead

Krsna Book 14:

Brahman realization or Paramātmā realization are also not possible even after one searches for many, many years unless one is touched by the wonderful effect of devotional service.

Krsna Book 20:

Unless one is able to control the senses and engage them in the transcendental loving service of Mukunda, there is no possibility of salvation.

Krsna Book 28:

Unless one is constantly situated on that transcendental platform, it is not possible to understand the spiritual nature.

Krsna Book 30:

“Yet how could Kṛṣṇa take Her away alone, leaving all of us aside, unless She is extraordinarily qualified and beautiful? She must have taken Kṛṣṇa into the deep forest and told Him, ‘My dear Kṛṣṇa, I am now very tired. I cannot go any further.

Krsna Book 36:

After all, man proposes, God disposes. We may make very great plans, but unless they are sanctioned by the supreme authority, they will fail. Everyone in this material world knows that the supernatural power is the ultimate disposer of everything.

Krsna Book 38:

Unless one is recognized by the Supreme Personality of Godhead, his life cannot be successful.”

Krsna Book 71:

Unless we are victorious over all the kings, no one can perform this Rājasūya sacrifice. In other words, it is to be understood that King Yudhiṣṭhira cannot perform this great sacrifice without gaining victory over the belligerent King Jarāsandha.

Krsna Book 73:

Just by dint of their being in front of the Supreme Personality of Godhead, all reactions to their sinful activities were washed away. Therefore, without reservation, they surrendered themselves at the lotus feet of the Lord. It is stated in the Bhagavad-gītā that unless one is freed from all sinful reactions, one cannot fully surrender unto the lotus feet of the Lord. All the princes who saw Lord Kṛṣṇa forgot all their past tribulations. With folded hands and with great devotion, they offered prayers to Lord Kṛṣṇa, as follows.

Krsna Book 80:

This means that the brāhmaṇa was a perfect devotee, because unless one is a perfect devotee he cannot achieve the highest standard of knowledge. It is stated in the Bhagavad-gītā that a person who has come to the perfection of knowledge surrenders unto the Supreme Personality of Godhead.

Krsna Book 84:

They were amazed upon hearing Him speak the absolute philosophy of life in such a concise way. Unless one is very much advanced in knowledge, one thinks his body to be his self, his family members to be his own, and the land of his birth to be worshipable. From this concept of life, the modern ideology of nationalism has sprung up.

Krsna Book 87:

Under the spell of the material energy, represented by the threefold material qualities, the living entity is so entangled that he is not at all able to become free unless he is graced by the Supreme Lord. The living entity cannot conquer the influence of the material modes of nature by his own endeavor, but because material nature is working under the control of the Supreme Lord, the Lord is beyond its jurisdiction.

Krsna Book 87:

The personified Vedas continued: “Dear Lord, less intelligent men take to other ways of self-realization, but actually there is no chance of becoming purified from material contamination or of stopping the repeated cycle of birth and death unless one is a thoroughly pure devotee. Dear Lord, everything rests on Your different potencies, and everyone is supported by You, as stated in the Vedas: eko bahūnāṁ yo vidadhāti kāmān.

Krsna Book 87:

Let the mystic yogīs engage in their meditational service, and let the different sects engage in unnecessary arguing as to which is the best. But it is a fact that unless one is Kṛṣṇa conscious, unless one is engaged in devotional service, and unless one has the mercy of the Supreme Personality of Godhead, he cannot cross over this material ocean.” An intelligent person, therefore, gives up all stereotyped ideas and joins the Kṛṣṇa consciousness movement for factual liberation.

Krsna Book 87:

The impersonal view of the Absolute Truth is accepted by less intelligent men, because unless one is engaged in the service of the Lord one cannot understand how the Supreme is acting—one cannot even know the Lord's name. Everything about the Lord's activities and personal features is revealed to the devotee only through his loving service attitude.

Krsna Book 87:

One cannot take to Kṛṣṇa consciousness unless one is completely freed from all sinful activities. The very fact that the Māyāvādī claims to be one with the Supreme Lord means that he is not yet freed from the reactions of sinful activities.

Krsna Book 87:

One cannot be engaged in devotional life, or Kṛṣṇa consciousness, unless one is fully free from material contamination. Nārāyaṇa Ṛṣi informed Nārada Muni that the essence of all the Vedas and Vedic scriptures (namely, the four Vedas, the Upaniṣads, the Purāṇas and the Vedānta-sūtra) is to render transcendental loving service to the Lord.

Krsna Book 88:

In the Bhagavad-gītā, however, we get instruction from Lord Kṛṣṇa that one has to transcend this qualitative existence. Nistrai-guṇyo bhavārjuna: the mission of human life is to become transcendental to the three qualities. Unless one is nistrai-guṇya, he cannot get free from material entanglement. In other words, favors received from Lord Śiva are not actually beneficial to the conditioned souls, although materially such facilities seem opulent.

Krsna Book 89:

Unless one is a devotee, one cannot be equal to all living entities. A devotee is equally disposed toward the animals, the human beings and all living entities because he sees every living entity as a part and parcel of the Supreme Lord. In the Īśopaniṣad it is clearly stated that one who has come to the stage of seeing all living beings equally does not hate anyone or favor anyone.

Renunciation Through Wisdom

Renunciation Through Wisdom 2.7:

Compared to other species, human beings are certainly endowed with good intelligence, yet unless they are devotees of the Lord, all their thinking is limited within mundane boundaries. Therefore it is impossible for the mundane mind to approach the transcendence. But instead of surrendering to the Supreme Lord or His representative, the empirical philosophers try to explain away as "unmanifest" that which is beyond their mundane minds. This is known as the logic of the frog in the well.

Sri Isopanisad

Sri Isopanisad 10, Purport:

This mantra states that the instructions of vidyā (knowledge) must be acquired from a dhīra. A dhīra is one who is not disturbed by material illusion. No one can be undisturbed unless he is perfectly spiritually realized, at which time one neither hankers nor laments for anything. A dhīra realizes that the material body and mind he has acquired by chance through material association are but foreign elements; therefore he simply makes the best use of a bad bargain.

Sri Isopanisad 17, Purport:

Unless one is accustomed to devotional practice, what will he remember at the time of death, when the body is dislocated, and how can he pray to the almighty Lord to remember his sacrifices? Sacrifice means denying the interest of the senses. One has to learn this art by employing the senses in the service of the Lord during one's lifetime. One can utilize the results of such practice at the time of death.
