The wall of division

Went to Wagga border yesterday , it was hot summer day waiting for beating Retreat at a temperature of 47 degrees along with more than 10000 crowd . There was a joy in people waiting to see this , saying slogans like hindustan jindabad etc etc .
What is difference between the human being this and that side , if both are human then why there is a gate seperating them . What is this feeling and emotion that makes wall among people . For me this kind of emotion is hard to understand . Being together for long and suddenly something happens ,and you face your back from other . what is this feeling ??
How can there be a wall between two brothers of same blood ? I heard this somewhere , human is more intelligent than any other animal or living things . Think they degrading themselves from having called intelligent . Now Human is more oriented towards .. sex , money , ego , and destructive entertainment . Too busy to think what they are and what they want .
There is no one who is humble to follow the Gods word 'IF SOMEONE SLAPS ON YOUR LEFT CHEEK , GIVE HIM RIGHT TOO ' . All the solution to a problem these days is followed by destruction only . Why cant they talk it out .
There is a wall 'WAGHA BORDER' , there is a wall 'RELIGION' , there is wall 'AT FAMILIES' and there is a wall ' INSIDE HUMAN'.
May be some people or external factor is causing all that . But listen to your innerselves and Come out and break the wall , and lets call ourselves human . Just need to be humble to do all that . Start saying sorry to each and everyone leaving your ego , hate etc behind . See how beautiful is the world . Lets not destruct such a wonderful and beautiful creation 'OUR WORLD '.
JUST BE GOOD TO YOU AND YOURSELVES . And allign the same energy that you carrying for destruction into construction . And Lets BREAK THE WALL .
