Man creates comparison because ego is possible only if nourished by comparison continuously. But then you will have two outcomes: sometimes you will feel superior, and sometimes you will feel inferior. And the possibility of feeling inferior is greater than the possibility of feeling superior, because there are millions of people: somebody is more beautiful than you, somebody is taller than you, somebody is stronger than you, somebody seems to be more intelligent than you, somebody is more learned than you, somebody is more successful, somebody is more famous, somebody is this, somebody is that. If you just go on comparing, millions of people... you will gather a great inferiority complex. But it doesn't exist, it is your creation.
