So śāstra says, therefore, nāyaṁ deho deha-bhājāṁ nṛloke kaṣṭān kāmān arhate viḍ-bhujāṁ ye (SB 5.5.1). Śāstra says ayaṁ deha, this body, human body . . . nāyaṁ deho nṛloke, deha-bhājāṁ nṛloke. Nṛloke means in the human society. The animals . . . nāyaṁ deho deha-bhājāṁ nṛloke kaṣṭān kāmān arhate viḍ-bhujāṁ ye. Viḍ-bhujām means an stool-eater animal, stool-eater animal, hog. You know. Although it is not very easily found in the cities, in our Indian villages, there are so many stool-eater hogs loitering in the street, in the village. The only business is, "Where to find out stool?" This is the business. Whole day and night they are working, to find out stool. So if human being is educated to find out his eatables . . . of course, the hog's eatables are the stool. They like it very much, very palatable thing. Similarly, we also, for some palatable things, we also work day and night. But śāstra says, na ayaṁ deho deha-bhājāṁ nṛloke kaṣṭān kāmān arhate. Why this human society should be trained up to work so hard simply for eating, sleeping, mating and defending? This is not good.
Then what is it meant for, human life? Tapa. Tapasya. Tapo divyaṁ yena śuddhyet sattvam (SB 5.5.1). The human life's business is to accept tapasya, voluntarily accepting some inconvenience of life. That is called tapasya. Tapa means some trouble. Just like to become brahmacārī, it is tapasya. Just like we are prescribing this formula: "No illicit sex, no intoxication, no meat-eating, no gambling." People want to do it. People want illicit sex. The whole city is full of pictures, simply how to indulge in illicit sex. Then meat-eating—big, big signboard—and intoxication, wine shops. They want it. That is the natural propensity. Loke vyavāyāmiṣa-madya-sevā nityā hi jantor na hi tatra codanā (SB 11.5.11). You do not require to encourage them in these things. They have got natural tendency. That is material world—to enjoy unrestricted sex life, to eat meat, fish eggs, āmiṣa . . . āmiṣa-madya-sevā. Āmiṣa means eat meat, fish, eggs. These are āmiṣa. And vegetarian means nirāmiṣa. So āmiṣa-madya-sevā. Madhya means intoxication. Either wine or cigarette or bīḍī or gāñjā, bhāṅg, teas, coffees, they are all intoxication. So āmiṣa-madya-sevā and vyavāya. Vyavāya means sex life. You do not require to educate them. In the school, college, the boys and girls are not, I mean, given lesson . . . of course now, I think, they are now giving lesson also. But naturally, without any lesson, they know how to do it. Similarly, without an education, one can take to intoxication. So these things are natural. But when we try to stop these material instincts, that is called tapasya, tapasya.
