Retold by Mystic Sudhir from an ancient Buddhist Story
Once there lived a demon who had a peculiar diet: he fed on the anger of others. And as 
his feeding ground was the human world, there was no lack of food for him. He found it quite easy to provoke a family quarrel, or national and racial hatred. Even to stir up a war was not very difficult for him. And whenever he succeeded in causing a war, he could properly gorge himself without much further effort; because once a war starts, hate multiplies by its own momentum and affects even normally friendly people. So the demon’s food supply became so rich that he sometimes had to restrain himself from over-eating, being content with nibbling just a small piece of resentment found close-by.
