A young Indian boy went to the tribe’s Chief and asked
“Sometime people are good and sometimes people are bad, I cannot understand why they are not always the same.”
The Chief said “Inside people there are 2 wolves, a good wolf and a bad wolf. The wolves fight each other. So sometimes people listen to the good wolf, sometimes they listen to the bad wolf.”
The boy went away to think about it. He came back to the Chief some time later to ask: “But then, which wolf will win?”
The Chief replied “The one you feed.”
