The purpose of a fish trap is to catch fish, and when the fish are caught, the trap is forgotten. The purpose of a rabbit snare is to catch rabbits. When the rabbits are caught, the snare is forgotten. The purpose of words are to convey ideas. When the ideas are grasped, the words are forgotten. Where can I find a man who has forgotten words? He is the one I would like to talk to. -- Chuang-Tzu
