A man would know the end he goes to, but he cannot know it if he does not turn, and return to his beginning, and hold that beginning in his being. If he would not be a stick whirled and whelmed in the stream, he must be the stream itself, all of it, from its spring to its sinking in the sea.
Ursula K. Le GuinWho knows a man's name, holds that man's life in his keeping. Thus to Ged, who had lost faith in himself, Vetch had given him that gift that only a friend can give, the proof of unshaken, unshakeable trust.
