This is very nice explanation. Simply by seeing, "Oh, here is a nice, beautiful girl," "Oh, here is a nice, beautiful boy," similarly, "Oh, here is Kṛṣṇa, here is Kṛṣṇa's kathā, here is Kṛṣṇa's topics, oh, here is Kṛṣṇa's temple." Just like, another example is given. Just like the waves of the river. It goes down. We have seen that little river... What is that? Varta? Always going down. In Japan also, I have seen that little river, with sound, going down, going down. So similarly, as the river is going after the sea spontaneously, without any artificial attempt, so such spontaneous love for Kṛṣṇa, or God, that is the perfection of yoga. This is yoga. Yoga means connection. So that connection... In the beginning we may make, revive that connection artificially, but when the connection will be spontaneous, without any check, just like the river water is going down incessantly... Nobody can check it. Ahaituky apratihatā. And why the river is going there? There is no cause. It is going there. Similarly, when our love for Kṛṣṇa will be gliding down like that, without any cause... Without any cause... Generally... The same example again, that spontaneous love does not depend on any cause without. Cause is there. Cause is there, love. There is no other cause. So it is called ahaituky apratihatā. Ahaitukī means without any cause. Just like we generally go to the temple, to the church, with a cause. Just like in Christian church they go. There is cause: "God, give us our daily bread." The cause is bread. "Therefore I have come to church." But when you go to church without any cause, that is real love. "God will give me bread; therefore, let me go to church," this is also nice, but this motivated faith may be lost. If we approach God for some material benefit, for personal sense gratification, that may break at any time. So that is not real love. Real love is without cause. And apratihatā. Apratihatā means which cannot be checked. My love for God cannot be checked by any material condition. Nobody can say that "Because I am poor man, I have to work so hard, I cannot love God now." People say like that. "We shall wait. When I get millions of dollars in my bank balance, then I shall take to Kṛṣṇa consciousness. Now let me earn money." You see? This is not bhakti or attachment. Mayy āsakta. Mayy āsakta manāḥ pārtha yogaṁ yuñjan mad-āśrayaḥ. Mad-āśrayaḥ means "under My protection." Kṛṣṇa says. So taking shelter of Kṛṣṇa or His representative... Mat means "My man" also. Mad-āśrayaḥ, take shelter of Kṛṣṇa or His representative, and try to practice the yoga by which you will have spontaneous love for Kṛṣṇa.
So this practice, according to Vedic instruction... Because we have no attachment. So for making attachment, there are some regulative principles by which you can increase the attachment. Just like we say, "No illicit sex." That means... Illicit sex means those who are too much attached to sex; otherwise, there is no question of illicit sex. According to Vedic system one is married, and married means the girl has got a husband, and the boy has got a wife. So living on religious principles, they can satisfy their sex life for begetting nice children. So there is no prohibition. That is allowed. But illicit sex means your attachment for sex is increased, not for Kṛṣṇa. Therefore it is forbidden. No meat-eating. Meat-eating or fish-eating or egg-eating, nonvegetarian diet, it is simply attachment of the tongue. Nobody dies without meat-eating. That's not a fact. When we were children, we were babies, we were depending on milk, either mother's breast milk or cow's milk. Therefore cow is also our mother. Just like we drink breast milk from my mother, similarly, we drink milk from mother cow. Therefore meat-eating is prohibited. You cannot kill your mother. That is a great sin. You cannot. But people have become so sinful that they have no consideration that "I am going to kill my mother. I am so ungrateful that the mother who supplied her blood to feed me, to keep me living, now I am grown-up, I am going to kill my mother." This is my advancement of education, that "I have learned how to kill my mother." Therefore, in every religion the killing is prohibited or very much restricted. So in your Christian religion, the first item is, "Thou shalt not kill." But everyone is violating this first commandment. Then where is your claim to become a Christian? If you violate the injunction given by Lord Jesus Christ, then where, how you become a Christian? That is our question. Either Christian or this or that, killing is most sinful. This should be avoided.
Therefore in the beginning, to increase attachment for Kṛṣṇa... Because my business is to increase my spontaneous attachment for God. That is the business of human life. This is a chance. Because in the human form of life you can do that. And as soon as you increase your attachment for Kṛṣṇa, then your life is successful. Successful means that you haven't got to accept any more this material body. You will get a spiritual body and go to Kṛṣṇa, or go to home, go back to Godhead. So if you increase your attachment for Kṛṣṇa, the benefit is that you make a solution for all the problems of life. It is scientific. Mayy āsakta manāḥ pārtha. So in the beginning, in order to increase your attachment for Kṛṣṇa, you have to follow the regulative principles, "Don't do this." Just like a doctor gives you prescription, "Don't eat this. Don't do this," similarly, there are so many "don't"s and so many "do"s. So we have to accept the "do"s, not the "don't"s. Ānukūlyena kṛṣṇānu-śīlanam (CC Madhya 19.167). This is called favorably cultivating Kṛṣṇa consciousness. We have to accept the "do"s, not the "don't"s. Ānukūlyasya saṅkalpa, ānukūlyena kṛṣṇānuśīlanam. We have to accept the favorable things. So if illicit sex life is unfavorable for my advancement in Kṛṣṇa consciousness, I must accept it. You cannot argue. That will not help you. Similarly, intoxication. Similarly, meat-eating. Similarly, gambling. Because these are the four pillars of sinful life: illicit sex, meat-eating, intoxication and gambling. The roof of sinful life is held by these four pillars.
