At the present moment, the population is so much degraded. There is no restriction. That is the difference between animal life and human life. Human life is meant for restriction. The more you restrict your material sense gratification, the more you are advanced. This is the standard. Not that, "Because I have got the tendency to act like this, let me do it unrestrictedly." That is not human civilization; that is cats' and dogs' civilization. Human civilization means tapasya, austerity. Tapo divyaṁ putrakā yena śuddhyet sattvam (SB 5.5.1). Sattva. We have to purify our existence. That is the aim of human life. We have to purify our existence.
What is the impurification of existence? The impurification of existence is this birth, death, old age and disease. Janma-mṛtyu-jarā-vyādhi-duḥkha-doṣānudarśanam (BG 13.9). Everyone is inclined to live, but nature will not allow you to live. Nobody likes to die, but nature will force you to become dead. Nobody wants to become old man, but nature will force you to become old man. Janma . . . and nobody wants to suffer from diseases, but nature will force you to suffer from diseases. These are the problems. But the rascal civilization, they do not know what is the real problem. They're dealing with petrol problem. Just see. Petrol problem, you have created another problem. Already there is problem. You have created, by so-called civilization, petrol problem. Before these motorcars, the people were living very happily. They were transporting. But there was no such civilization that for your earning livelihood you have to go hundred miles away from your home to work there. Therefore you require vehicle. Then you require petrol. Then you require so many nice road. So many things will be. But formerly, it was village. They will take it, "This is primitive." But remaining primitive, you are more happy than becoming so-called civilized, creating so many problems. You have already problems, but people are so rascal, so blind, they do not see to the real problem. They artificially create problem and try to solve it. Instead of touching the real problem, that is set aside.
