Prabhupāda: It is . . . try to understand that the Supreme Lord, God, is pure. And His kingdom is also pure. And anyone who wants to enter there, he must be pure. That is very natural, that if you want to enter into some particular society, you must qualify yourself. There are . . . qualification is, to go back to home, back to Godhead, the qualification is that you should not be materially contaminated.
And what is that material contamination? The material contamination is sense gratification, unrestricted sense gratification. That is material contamination. So you have to make yourself free from material contamination. Then you become eligible to enter into the kingdom of God.
That process of being freed or being washed of all material contamination is yoga system. Yoga system does not mean that you sit down for fifteen minutes for so-called meditation and you continue all your material contamination. Just like if you want to be cured from a certain type of disease, you have to follow the regulation made by the physician.
Similarly, in this chapter the process of yoga practice is recommended, how you have to do it. So that means if you execute those prescribed methods, then you become freed from material contamination. Then you are actually situated for linking up, for making connection with the Supreme. That is Kṛṣṇa consciousness.
Our method is directly to connect you. That is the special gift of Lord Caitanya—immediately to contact him with Kṛṣṇa. Because ultimately you have to come to that point, Kṛṣṇa consciousness. So here this method is that directly, immediately. And it is practical also. Those who have no qualification, they simply by coming in contact with the Society they have become highly advanced in Kṛṣṇa consciousness. This is practical.
So in this age we have to give chance to the people, direct contact. No slow process method will help them, because the life is very short, they are not very much fortunate and the association is very bad. Therefore, direct contact—harer nāma (CC Adi 17.21).
Simply Kṛṣṇa is presented in the form of His transcendental name, and you contact Him immediately by hearing. You have got natural instrument, hearing. You simply hear "Kṛṣṇa" and you become uncontaminated immediately.
Go on.
Revatīnandana: "Kṛṣṇa consciousness is the perfect stage, being freed of all contaminations. This is confirmed in the Bhagavad-gītā. After many, many births in execution of pious activities, when one is completely freed from all contaminations and from all illusory dualities, one then becomes engaged in the transcendental loving service of the Lord."
Prabhupāda: Yes. Yeṣāṁ anta-gataṁ pāpam. The exact verse in the Bhagavad-gītā is yeṣāṁ anta-gataṁ pāpam (BG 7.28).
Pāpam means sin. One who has completely ended sinful activities, janānāṁ puṇya-karmaṇām—persons who have simply executed pious activities—such person becomes fixed up in Kṛṣṇa consciousness without any dualities. Because our mind is flickering, so dualities will always come: "Whether I shall accept it or not?" "Whether I shall become Kṛṣṇa conscious or another conscious?" These problems are always there.
But if one is advanced by pious activities in the previous life, then he is fixed up steady, "I'll become Kṛṣṇa conscious." So this method, this chanting Hare Kṛṣṇa method, even in your previous life you did not act very piously or in this life, it doesn't matter. If you kindly take seriously this simple method, Hare Kṛṣṇa chanting, you become immediately pure—but with the determination that you'll not contact any more impious activities.
Just like in our Society we make four restriction. Anyone who desires to be initiated in our Society, we put four principles. No illicit sex life. We don't say that don't have sex life. No illicit sex life. You get yourself married, and for children you can have sex life; not for another purpose. So, no illicit sex life, no intoxication.
Our students, they do not smoke even, they do not take tea even, coffee, so what to speak of other things. So they are so pure. No gambling and no animal food. That's all. If you simply follow these four principles, then you become immediately uncontaminated. Immediately, without any further endeavor.
So Kṛṣṇa consciousness movement is so nice that as soon as you join, you become immediately uncontaminated. But do not contaminate again. Therefore these restriction. Because our contamination begins from these four kinds of bad habits. But if we check, then there is no question of contamination. As soon as I take to Kṛṣṇa consciousness I become free.
