One evening a Cherokee elder told his grandson about a battle that goes on inside people.
He said, "My son, the battle is between the two ‘wolves’ that live inside us all.
One is Unhappiness or Evil – It is anger, jealousy, fear, regret, greed, arrogance, sorrow, self-pity, resentment, inferiority, false pride, superiority, weakness and ego.
The other is Happiness or Good – It is joy, love, hope, serenity, benevolence, peace, empathy, kindness, generosity, truth, humility, faith, strength and compassion."
The grandson thought about it for a while and then asked his grandfather, "Which wolf wins?"
The old Cherokee simply replied, “The one you feed." – Cherokee Elder
