One evening an old Cherokee told his grandson about a battle that goes on
inside people. He said "My son the battle is between 2 wolves -
 
"One wolf is evil; it is known thru anger, envy, sorrow, regret, greed,
arrogance, self-pity guilt, resentment, inferiority, lies, false pride,
superiority, and ego.
 
"The other wolf is good and it is known thru joy, peace, love, serenity,
humility, kindness, benevolence, empathy, generosity, truth, compassion and
faith". 
 
The grandson thought about it for a minute and then asked his grandfather,
"Which wolf wins?
 
The old Cherokee simply replied "THE ONE YOU FEED"
