It is no secret. All power is one in source and end, I think. Years and distances, stars and candles, water and wind and wizardry, the craft in a man's hand and the wisdom in a tree's root: they all arise together. My name, and yours, and the true name of the sun, or a spring of water, or an unborn child, all are syllables of the great word that is very slowly spoken by the shining of the stars. There is no other power. No other name.
Ursula K. Le GuinAnd he began to see the truth, that Ged had neither lost nor won but, naming the shadow of his death with his own name, had made himself whole: a man who, knowing his whole true self, cannot be used or possessed by any power other than himself, and whose life therefore is lived for life's sake and never in the service of ruin, or pain, or hatred, or the dark.
