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 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 restrictions. 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. Now if I become cautious not to accept these four principles, then I am free, I am continuing uncontaminated. This is the process. But if you think that because Kṛṣṇa consciousness makes me free, so let me indulge in all these four principles and I will get free after chanting. That is cheating. That will not be allowed. Once you are free, but don't do it again. But if you think "I shall do it and make myself free."
Just like in some religious process it is said that you commit all kinds of sins and go to the church and simply confess, you are free. So this doing and confessing, doing and confessing is going on. But here, no. If you are freed, that's all right. But don't do it again. That is the purpose of confession. Confession, if you confess that "I have done these sinful activities," so why should you do again? If you confess that it is sinful, pickpocketing is sinful, take for example. So by confessing you are freed, then why shall you do it again? It requires little intelligence. It does not mean that because by confessing I become freed, I shall go on continuing this and again confess and become freed. No. That's not good. If it is not good, you have confessed that it is not good, then you should not do it again. That is the purpose. Not that you do it and confess, do it and confess, do it and confess. This business is not good. So we should be careful, the Kṛṣṇa consciousness movement, that these four principles, if you indulge in unrestricted, then you become contaminated. But if you take precaution in executing these four principles. We don't say that you don't have sex life. You have. But for this purpose, not for this purpose. Similarly you eat but you eat this way, not that way.
So defend, Kṛṣṇa also advised Arjuna to defend. So defend is also not prohibited provided it is for right cause. So in this way if we can come to Kṛṣṇa consciousness immediately we become free from all contamination. And if we take precaution of these four principles, then our life is pure. And if we can continue this pure life till the time of death you are sure to be transferred to the kingdom of God. Go on. That is stated in Bhagavad-gītā you have already read: tyaktvā dehaṁ punar janma naiti (BG 4.9). By giving up this body, that person who is fully in Kṛṣṇa consciousness, he does not come back again to take part in this material world. This yogi who is coming to a good family, to a righteous family or rich aristocratic family, they are coming back. But if you are perfect Kṛṣṇa consciousness you are no more coming back. You are situated in the Goloka Vṛndāvana in the spiritual sky. So we should try not to come back again. Because if I come back again, suppose I have got very nice chance. I have got birth in a very good family, in rich family. But if I cannot utilize it properly, then again I degrade myself to other sort of life. So why should we take this risk. Better complete Kṛṣṇa consciousness in this life. It is very simple. It is not very difficult. Simply to keep yourself in thoughts of Kṛṣṇa. That's all. It is very simple thing. Then you are assured to your next birth in the spiritual sky in the kingdom of God or in the Goloka Vṛndāvana.
