Two wolves.
 
One evening an old Cherokee told his grandson about a battle that goes on inside people.

He said, ' My son, the battle is between two ' wolves ' inside us all..

One is Evil. -  It is anger, envy, jealousy, sorrow, regret, greed, arrogance, self-pity, guilt, resentment, inferiority, lies, false pride, superiority, and ego.

The other is Good. -  It is joy, peace, love, hope, 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. '
