Pots are made of clay, but the hollow space in them makes the essence of the pot. And this essence comes from an intangible something in the spirit of the potter which he is able to fuse into the shape of his work, which he blends into his knowledge of the throwing, the glazing, and the firing, so that every piece from his hand is as much his own as his signature and heartbeat. Only then will the two be good, that is, alive. And the more highly developed a potter is as a human being, the better his pots. For there is no real beauty without character. Lao Tse
