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 is Evil. It is anger, envy, sorrow, regret, greed, arrogance, self-pity, guilt, resentment, inferiority, lies, false pride, superiority and ego.
The other is God. 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."
Legend ?? Don't know, but I heard it years ago, and it stuck with me.. So I thought of it when I read your question. Good luck.
