Viṣaya means the sense enjoyment. The primary sense enjoyment is eating, sleeping, sex life and defense. So where there is want of these four facilities? The birds have got these facilities. The beasts, they . . . for sex life, the birds and beasts, they have got automatically. Two birds are born, two eggs: one male, one female, from the very beginning. We are also born brother and sister. But human society does not allow sex between brother and sister. Still formality is there. But that is also going on. Human life is advanced. That is going on.
In India one Punjabi, that father was anxious to get the daughter married, and the brother wrote the father, "My dear father, don't bother about my sister's marriage. We have arranged ourself, brother and sister." You see? So sex life is so strong. Although socially it is forbidden that brother and sister should not marry or should not have sex life, but that is also come. 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.
