I can find so much peace and serenity from the stories and legends of the Native Americans.
An elder Cherokee Native American was teaching his grandchildren about life. He said to them, "A fight is going on inside me ... it is a terrible fight and it is between two wolves. One wolf represents fear, anger, envy, sorrow, regret, greed, arrogance, self-pity, guilt, resentment, inferiority, lies, false pride, superiority, and ego. The other stands for joy, peace, love, hope, friendship, empathy, generosity, truth, compassion, and faith. The same fight is going on inside you, and inside every other person, too."
They thought about it for a minute and then one child asked his grandfather, "Which wolf will win?" The old Cherokee simply replied... "The one you feed."
