Every living entity has got this pravṛtti, means propensity. What is that? Sense enjoyment. Loke vyavāyāmiṣa-madya-sevā nityā hi jantor (SB 11.5.11). Jantuḥ means living being. Nitya, always, he has got the propensity, vyavāyāmiṣa-madya-sevā. Vyavāya. Vyavāya means sex life and āmiṣa means meat-eating. Vyavāya āmiṣa, madya-sevā, and intoxication. These are natural instincts of all living entities. Even amongst the ants these propensities are there. Those who have studied . . . the ants are very much fond of being intoxicated. Therefore they find out sweet, sugar. Sweet is intoxication. Perhaps you know, all. The liquor is made from sugar. Sugar is fermented with acid, sulphuric acid, and then it is distilled. That is liquor. Therefore too much sweet-eating is prohibited.
So loke vyavāya āmiṣa mada-sevā nityas tu jantuḥ. This is propensity. Material life means every living entity has got these propensities. But they have to be restricted. Pravṛttiḥ eṣaṁ bhūtānām. That is natural instinct. But if you can stop them, that is your excellence. That is called tapasya. Tapasya means I have got naturally some propensities, but that is not good. Not good in this sense: if we continue that propensity, then we have to accept this material body. This is the law of nature. There is a verse, pramattaḥ . . . what is called, that? Now I'm forgetting that. That everyone is mad, mad after sense gratification. Na sādhu manye yata ātmano 'yam asann api kleśada āsa dehaḥ (SB 5.5.4). So long we'll continue this propensity of sense enjoyment, you'll have to accept body. That is birth and death. So long.
Therefore, the process should be how to make zero all these propensities. That is perfection. Not to enhance it. Nūnaṁ pramattaḥ kurute vikarma yad indriya-prītaya āpṛṇoti. Nūnam, "alas," "indeed"; pramattaḥ, these madmen. They are mad, those who are after these propensities, vyavāya āmiṣa mada-sevā, sex, intoxication and meat-eating. They're all madmen. Pramattaḥ. Nūnaṁ pramattaḥ kurute vikarma (SB 5.5.4). Vikarma means activities which are prohibited. We see, for these three things, āmiṣa-mada-sevayā, for sex life, for meat-eating, for drinking, people are working. Not only working; dishonestly working. How to get money, how to get money, the black market, white market, this, that, only for these three things: āmiṣa-mada-sevā, meat-eating, intoxication.
