Two Wolves'
This is the best I have ever heard it explained...
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.'
