One evening a Cherokee elder sat with his grandson to tell him about the battle that goes on within people.
He said, "My son, the battle is between two wolves inside us all. One is evil. This wolf speaks with anger, envy, jealousy, hatred, sorrow, regret, greed, arrogance, self-pity, guilt, resentment, inferiority, lies, false pride, superiority, and ego.
The other is good. This wolf speaks with joy, peace, love, hope, serenity, humility, kindness, and caring, empathy, respect for self and others, generosity, truth and faith. The same fight is going on inside you - and inside every other person, too."
The grandson listened to his grandfather's words and asked, "Which wolf wins?"
The wise Cherokee elder looked into his grandson's eyes and replied, "The one you feed".
