“It is no secret. All power is 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 chid, 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.”
Wizard of Earthsea by Ursula Leguin
