Viḍ-bhujām. Viḍ means stool, and bhujām means eater. So the stool-eater's sense gratification is not meant for this human form of life. Stool-eater means these hogs. The hogs' sense gratification is not meant for this human form of life. Restriction. Therefore in the human form of life there is marriage system. Why? What is the marriage and prostitution?
Marriage system means restricting sex life. Marriage system does not mean that you get a wife—ah, without any payment you go on unrestricted sex life. No. That is not marriage. Marriage means to restrict your sex life. He will hunt for sex life here and there—no, you cannot do that. "Here is your wife, and that is only for child." It is restriction.
There are four things. Loke vyavāya 'miṣa mada-sevā nityas tu jantuḥ. Vyavāya, sex life; and meat-eating, āmiṣa. Āmiṣa means eating meat, fish, eggs. So vyavāya means sex. Sex and meat-eating, non-vegetarian diet. Mada-sevā, intoxication. Mithyā sa jantuḥ. Every conditioned soul has natural inclination, pravṛtti. But one has to control that. That is human life. If you put yourself in the waves of natural inclination, that is not human life. You have to restrict. The whole human life is meant for learning restriction. That is human life. That is perfect Vedic civilization.
