Materialistic way of life is that I have got nice senses, let me enjoy the senses to the fullest extent. That is materialistic way of life. Just like cats, dogs, and hogs. The hogs, whenever they are sexually inclined, they don't care for whether it is his mother or sister or this or that. You see? That is stated in the Śrīmad-Bhāgavatam: nāyaṁ deho deha-bhājāṁ nṛloke kaṣṭān kāmān arhate viḍ-bhujāṁ ye (SB 5.5.1). Viḍ-bhujām, viṭ 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'll 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 vyavāyam... 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. Tapo divyaṁ yena śuddhyet sattvam (SB 5.5.1). One has to purify his existence. What is that existence? I am spirit, ever existing, eternal. Now I have contaminated this matter, therefore I am suffering. So I have to purify. Just like you have to get free from the diseased condition. When you get fever you take treatment. Not unrestricted enjoyment. The doctor says, "Don't do this, don't do this, don't do this." Similarly this human form of life is to get out of this diseased condition of life having a material body. If we don't restrict then where is the treatment? Where is the cure? The whole system is restriction. Tapo divyam (SB 5.5.1). Just to concentrate one's activities in austerities, penances, for transcendental realization. That is human form of life.
