"Evil (ignorance) is like a shadow--it has no real substance of its own, it is simply a lack of light. You cannot cause a shadow to disappear by trying to fight it, stamp on it, by railing against it, or any other form of emotional or physical resistance. In order to cause a shadow to disappear, you must shine light on it."
~Shakti Gawain.
One of my teachers said, "Evil spelled backwards is Live. Devil spelled backwards is Lived. All they are is when you aren't. When you aren't consciously living in the light."
