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.
