Prabhupāda: When Kṛṣṇa became his spiritual master He chastised him in the beginning, aśocyān anvaśocas tvaṁ prajñā-vādāṁś ca bhāṣase (BG 2.11), that "You are talking like learned man, but you are a fool number one because you are talking on the bodily concept of life." So this sex life increases the bodily concept of life. Therefore the whole process is to reduce it to nil. Bob: To reduce it over the stages of your life?
Prabhupāda: Yes. Reduce it. Just like a boy is trained up as a student up to twenty-five years, restricting sex life. Brahmacārī. So some of the boys, they remain naiṣṭhika-brahmacārī. He, because he's given education, so if he becomes fully conversant, he doesn't like to marry. But one who has not such restraint, he's allowed to marry. That is also restricted, that he cannot have sex life without being married. Therefore in the human society there is marriage, not in the animal society.
But we are reducing human society gradually to animal society. We are forgetting marriage. That is also written in the śāstras: svīkāra eva codvāhe (SB 12.2.5). In the Kali-yuga there will be no marriage performances, but the boy and the girl, they'll simply agree to live together. Dāmpatye 'bhirucir eva hi (SB 12.2.3). And their relationship will exist on sexual power. If the man or the woman is deficient in sex life, then there is divorce.
So on this philosophy . . . there are many Western philosophers like Freud and others, they have written so many books. But according to Vedic culture, we are not interested. We are interested only for begetting children, that's all, not to study the psychology of sex life. There is already psychology, pravṛtti, natural. Even if one does not read any philosophy, he'll be sexually inclined.
There is no need of philosophizing sex life. Nobody is taught sex life in the school and the colleges, but everyone knows it, how to do it. (laughs) So pravṛttir eṣā bhūtānāṁ nivṛttis tu mahā-phalam (Manu-saṁhitā). That is the general tendency. But education should be given to stop it. That is real education. (pause)
Bob: That, for today, is a radical concept, for nowadays.
Prabhupāda: Hmm?
Bob: Presently, in America, that's a radical concept.
Prabhupāda: Well, in America there are so many things which requires thorough reformation. And this Kṛṣṇa consciousness movement is that. When I went to your country, so I saw these boys and girls, they're living like friends. I said that "You cannot live as friends, you must get yourself married."
