Svarūpa Dāmodara: (laughs) Yesterday I stopped by to a gas station (laughter). And the man in the gas station he asked me, I was taking some petrol, and he asked me, "Hare Kṛṣṇa people how they get children?" He told me that he saw the girls are having children, "So do you allow sex?"
Prabhupāda: (indistinct) . . . us.
Svarūpa Dāmodara: Then he asked me, "Do you have free sex?" Like that. I said: "Never, that is never allowed, in fact, sex is allowed but within the marriage system not outside." Then he said that he doesn't want to get married and then I asked, "What do you want, sex?" "Yes," he said, he always wants to have like that but he doesn't want to get married. I said: "That is the greatest sinful activity."
Prabhupāda: (indistinct) . . . animals. Animals do not marry but they have sex life, so that means you are animal. You're not human being. The answer should be like that. Because marriage, this ceremony is not for fun. Amongst the animals but they have got sex, so you are like animals, so you are animal, you don’t claim to be human being. This is the answer. By your so-called scientific improvement you have become an animal, is it not? The animals they have sex life anywhere but they are not married, therefore you are animal. Is it not?
Svarūpa Dāmodara: Yes.
Prabhupāda: By your scientific improvement you are creating animals amongst human beings.
