It is Kali-yuga. So that sex life facility is there automatically by nature. So why there is forbidden, "Not this sex life, not that..." Just like we forbid, no illicit sex, that without marriage, there is no sex. One may argue, "What is the difference, married sex and not-married sex? The business is the same."
No, there is some meaning. This restriction mean to bring him to the position of the daivī sampat, sattva-saṁśuddhiḥ. The purpose is to bring him to the platform of daivī sampat. If he becomes like cats and dogs, then he cannot attain this daivī sampat. If there is rules and regulation, restriction following, then gradually he will come to the platform of daivī sampat. And what is the purpose of daivī sampat? Daivī sampad vimokṣāya: (BG 16.5) "If you develop your daivī sampat, then you become fit for vimokṣāya, for liberation." What is that liberation? Liberation means janma-mṛtyu-jarā-vyādhi (BG 13.9), liberation from these four things: no more birth, no more death, no more disease, no more old age.
So people are unaware, and they are not interested what is vimokṣāya, what is nibandhāya. Exactly like cats and dogs, they are after these four principles of material body. So this Kṛṣṇa consciousness movement is trying little bit. Success or no success does not matter. As we are servant of Kṛṣṇa, it is our duty to present the real thing. Now you accept, not accept. That is not my business. I can request you that you accept this principle and be liberated from these sufferings of material life. Janma-mṛtyu-jarā-vyādhi. But we have become careless. "Never mind I shall again take my birth, again die, I shall become dog." In this Hawaii sometime I was speaking in the university. So when I was speaking like that, one student said, "What is the wrong there if I become dog?" Yes, he flatly said. "I shall forget everything." So this is the university education, that one is not afraid of becoming a dog. He thinks that "This is also very good." So where is the humanity? Where is the human civilization? People are gone so down-trodden, so fallen. Therefore it is very, very difficult to raise them. Therefore Caitanya Mahāprabhu said, and the śāstras say, that people in this age are so fallen. It is very difficult to raise them by properly giving education. They will not take education. They will not be able. Therefore He has recommended, harer nāma harer nāma harer nāmaiva kevalam, kalau nāsty eva nāsty eva nāsty eva... (CC Adi 17.21). So we are trying our best. So only request is, those who do not comply with our rules and regulation at least, they may chant Hare Kṛṣṇa wherever they may remain. That is my request.
