I am not sure where this story came from but I have found it to be very helpful.
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, jealousy, sorrow, regret, greed, arrogance, self-pity, guilt, resentment, inferiority, lies, false pride, superiority and ego. The other is good. It is joy, peace, kindness, love, hope, serenity, humility, 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."
This is a wonderful story. So simple and yet so profound. Think about your daily life. What do you give your energy to? What do you spend time thinking about? Do you feed the evil wolf or the good wolf?
