to become actual human being, one has to undergo tapasya. Tapasā brahmacaryeṇa, jñānena, śamena, damena (SB 6.1.13). This is the prescription, that if you want to become actually a human being, then you have to undergo tapasya, brahmacarya, śama, dama, titikṣā (BG 18.42). These things have to be practiced. Not that because I want sense gratification, therefore let me under the name of independence, let me become naked and have sex life on the street. That day is coming. It already has come to some extent. They are taking this as freedom.
This freedom is not very good. This freedom means that as soon as you become so free that to have sex life on the street like cats and dogs and hogs, you will get your next life. Nature will give you very good chance that, "All right, you have got this human form of life to understand God, but you have misused it. Now you want to become hog? Please become hog." How you can check it? Is there any science to check? Because after this death, all this science and philosophy is finished after this body is finished. Then you are under the control of nature. What will you do? The nature will force you to enter the womb of a hog or a dog. How you can check it?
