Clay is molded to form a cup, But it is on its non-being that the utility of the cup depends. Doors and windows are cut out to make a room, But it is on its non-being that the utility of the room depends. Therefore turn being into advantage, and turn non-being into utility.
LaoziThe Tao never does anything, yet through it all things are done. If powerful men and women could venter themselves in it, the whole world would be transformed by itself, in its natural rhythms. People would be content with their simple, everyday lives, in harmony, and free of desire. When there is no desire, all things are at peace.
Laozi
