So in Bhagavad-gītā we'll find all the solutions of the human problems, all the solutions. Cātur-varṇyaṁ mayā sṛṣṭaṁ guṇa-karma-vibhāgaśaḥ (BG 4.13). Unless you divide the whole human society into four divisions, the brāhmaṇa, kṣatriya, vaiśya and śūdra... You must have to divide. You cannot say "classless society." That is useless society. Classless society means useless society. There must be an intelligent high class, ideal class of men to see the "Here is human civilization." That is brāhmaṇa. Cātur-varṇyaṁ mayā sṛṣṭaṁ guṇa-karma... (BG 4.13). Unless people see the ideal men, how they will follow? Yad yad ācarati śreṣṭhaḥ, lokas tad anuvartate (BG 3.21). The brāhmaṇa is compared with the brain of the body. Unless there is brain, what is the use of these hands and legs? If one's brain is cracked, madman, he cannot do anything. So at the present moment, because there is scarcity of brahminical qualified men in the whole human society... It is not meant... Brāhmaṇa is not meant for simply for India of Hindus. For the whole human society. Kṛṣṇa never says that the cātur-varṇyaṁ mayā sṛṣṭam (BG 4.13) is meant for India, or for Hindus, or for a class of men. For whole human society, there must be a very ideal intellectual man, so that people will follow. Brain, brain of the society. That is the teachings of Bhagavad-gītā. You cannot say that "We can do without brain." Suppose from your body if the brain is cut off, your head is cut off, then you are finished. What the hands and legs will do if there is brain, if there is no brain? So at the present moment there is scarcity of brain in the whole human society. Therefore, it is in the chaotic condition. So there is need, as it is stated in the Bhagavad-gītā. The human society, the whole human civilization, must be reformed in this way, that there are intellectual class of men, naturally. There are first-class intellectual class of men, second-class intellectual, third-class, fourth-class, like that. So the first-class intellectual man, they must be brāhmaṇas, in the brahminical qualification, and they must be Kṛṣṇa conscious. Then they can guide the whole society in the right way, and there will be no problem. This is Kṛṣṇa consciousness movement.
So here Kṛṣṇa says how to become Kṛṣṇa conscious. That is for the brāhmaṇas, or the intellectual class of men. That is being described by Kṛṣṇa. What is that? Mayy āsakta-manāḥ: "The mind should be attached upon Me, Kṛṣṇa." This is the beginning. Some way or other we have to... Our mind is attached to something else. Mind cannot be detached. We have got so many desires. So mind's business—to become attached. Therefore, I accept something, I reject something. This is mind's business. So you cannot become zero, you cannot become desireless. That is not possible. Our process... Just like others, they say, "You become desireless." That is a foolish proposal. Who can become desireless? It is not possible. If I am desireless, then I am a dead man. A dead man has no desire. So that is not possible. We have to purify the desires. That is required. Purify the desires. Sarvopādhi-vinirmuktaṁ tat-paratvena nirmalam (CC Madhya 19.170). This is called purification. Nirmalam. Tat-paratvena. Tat-paratvena means when God conscious, Kṛṣṇa conscious, then desires become purified.
So we have to come to the point of not desirelessness, but to the point of purified desires. That is wanted. Therefore here it is said, mayy āsakta-manāḥ: "You can not make your mind desireless, but you fix up your mind upon Me." That is required. Mayy āsakta-manāḥ pārtha. This is the yoga system. This is called bhakti-yoga, and this is called first-class yoga. That is described in the Bhagavad-gītā, that yoginām api sarveṣāṁ mad-gatenāntar-ātmanā (BG 6.47). The yogi, the first-class yogi, yoginām api sarveṣām... "There are different kinds of yoga systems, but the person who has accepted this bhakti-yoga, he is thinking of Me always." Just like these boys and girls they are being taught always thinking of Kṛṣṇa, "Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare." So if you read Bhagavad-gītā and chant Hare Kṛṣṇa, immediately you learn the whole science, how to become attached to Kṛṣṇa. This is called mayy āsakta-manāḥ. Mayy āsakta-manāḥ pārtha yogaṁ yuñjan, to practice yoga... This is bhakti-yoga. Mad-āśrayaḥ. Mad-āśrayaḥ means "under My direction," or "under My protection." Āśraya.
So if you read Bhagavad-gītā as it is, that is mad-āśrayaḥ. But if you interpret Bhagavad-gītā according to your rascal imagination, that is not Bhagavad-gītā. Therefore it is called mad-āśrayaḥ, "under My protection, as I am tea..." We are therefore presenting Bhagavad-gītā as it is. We do not change. Why should you change? What right you have got to change? If Bhagavad-gītā is a book of authority, and if I make my own interpretation, then where is the authority? Can you change the lawbook according to your interpretation? Then what is the meaning of that lawbook? That is not lawbook. You cannot change. Similarly, if you accept Bhagavad-gītā as the book of authority, you cannot change the meaning. That is not allowed. What right? If you have got some opinion, if you have got some philosophy, you can write in your own book. Why you are, I mean to say, killing others and yourself by interpreting Bhagavad-gītā? You give your own thesis in a different way. But these people, they take advantage of the popularity of Bhagavad-gītā and interpret in a different way according to their own whims. Therefore people do not understand what is Kṛṣṇa. That is the difficulty. And the purpose of Bhagavad-gītā is to understand Kṛṣṇa. And all the so-called scholars' and politicians' commentary is to banish Kṛṣṇa or to kill Kṛṣṇa—the Kaṁsa's policy. The Kaṁsa was always thinking of Kṛṣṇa, how to kill Him. This is called demonic endeavor. So that will not help you.
