Light and darkness

This is a re-telling of a legend of unknown origins, called Two Wolves.

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, 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.”
