Ego

Ego is a strange word.  But though it is strange, everyone has one.  It is the force behind who cause peace and war.  Force behind who bring about love and hatre.  Simply saying, it is feeling of that 'I' or 'Myself' and think that I am very important.  So if this is  my way to do this, other ways are wrong.  Because I am important and I should be right. 
But sometimes Ego will make one think he is wrong or make one feel   guilty just because only this act or feeling will make  Ego think it is right and important.  Strange isn't it?  But everyday we are doing it .....
