Darkness is a lower energy than light, and when you bring light to the presence of darkness you don't have to warn it, you don't have to tell it that it has to get away. It can't survive. Light dissolves darkness. And so does love dissolve hate and so does joy dissolve sadness and so does faith dissolve doubt and so on.
