There’s a Native American tale about an old man who was telling his grandson a story about two wolves.
The old man said, “There’s a fight between two wolves. One is an evil wolf, filled with anger, resentment, greed, sadness, rage, envy, pride, ego, vanity, and superiority. The other is a good wolf, filled with peace, light, kindness, generosity, love, compassion, humility, benevolence, grace, hope, compassion, and faith.”
“Which of the wolves will win the fight, grandfather?” asked the boy.
The old man paused, considering the boy, then said, “Whichever one you feed.”
