Any religious system—it doesn't matter—forbids, "Don't commit sinful life, you will suffer." So people have made a civilization that "There is no life, and you can go on irresponsibly, as you like, enjoy life, and never mind if I become a dog. What is the wrong there?" That's all. This kind of civilization must be stopped if we want to remain a human being. And if we don't want, if we want to remain as cats and dogs, that is a different thing. But if you want to remain as human being, you must live regulative principle. And that we are teaching. Our Kṛṣṇa consciousness movement is teaching regulative life for next spiritual life, back to home, back to Godhead. This is our mission. So regulative life means... Sinful life, if we become sinful, irresponsible, then another material body. That is the advice. Na sādhu manye yata ātmano 'yam asann api kleśada (SB 5.5.4). As soon as you get another material body, it is suffering. So try to realize these things. Therefore, punar-janma-jayāya. The whole aim should be how to conquer over again material... This is intelligence. This is intelligence.
So he is recommending, Śukadeva Gosvāmī, that this regulative life should be conducted: first of all tapasya. Tapasya means... Tapa. Tapa means voluntary suffering. That is called tapasya. The voluntary suffering means what is our enjoyment? First of all let us see. The enjoyment is if we can eat voraciously, eating, and if we can sleep thirty hours, and if we have got sex life without any discrimination, and don't care for defense. That's all. This is enjoyment life, material enjoyment means. Now, tapasya means denying all these things, denying. Eating as much as I require to maintain my body—this is tapasya, not that voraciously eating. Tapasya means practically not eating. That is tapasya: not eating. Raghunātha dāsa Gosvāmī, he was a very rich man's son. So he showed us the example, what is tapasya. He gradually reduced his eating, every alternate days a little butter. That's all. Raguṇatha dāsa Gosvāmī. And still, he was taking three times bath and hundred times... Sāṅkhyā-pūrvaka-nāma-gāna-natibhiḥ. He was offering obeisances flat hundred times and taking bath three times. Raghunātha dāsa Gosvāmī, those who have gone to Rādhā-Kunda, you have seen, the extreme tapasya. He was very rich man's son. In those days his father's income was twelve lakhs of rupees. He left his happy home and joined Caitanya Mahāprabhu and exemplified tapasya. He showed.
So tapasya generally means that first thing is that we should reduce our eating, sleeping, mating and defense. This is called tapasya, voluntarily accept. Suppose I am accustomed to eat very voraciously, and if I have to execute tapasya, that means I will have to reduce my eating to the point of no eating. But that is not possible. But that will create some trouble. But I will accept this trouble, this is called tapasya. I am habituated to sleep so many hours; I will have to reduce it. Yuktāhāra vihāraś ca. We don't say, "Don't sleep," but we say, "Reduce sleep as much as possible. Reduce your eating as much as possible." So this is called tapasya. And brahmacaryeṇa. Brahmacaryeṇa means completely cessation of sex life. So that is not possible to completely give up eating or completely sex life, but make it regulated. That is tapasya: eating, sleeping, mating, and defense as much as it is required. The aim should be to make it nil. That is called tapasya. Tapasā brahmacaryeṇa (SB 6.1.13). Brahmācārya means, strictly. Brahmācārya means that one should not look upon woman, "Oh, here is a very beautiful girl." That is also sex, subtle sex. And to talk, "Fsh, fsh, fsh, fsh," that is also subtle sex. So these things are to be avoided. There are eight kinds of subtle sex life. This is called brahmācārya. So according to Vedic śāstra, if one lives with one woman, one man, they are also brahmacārī. Not many. This is... If one cannot give up sex life, let him be satisfied with one man and one woman. That is also tapasya, that is also brahmacārī. But not that jumping from here, there, there, there, there, no, like monkey, no. (laughter) This is training. This is training.
