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.
LaoziThings exalted then decay. This is going against the Way. What goes against the Way meets an early end.
LaoziThere is something obscure which is complete before heaven and earth arose; tranquil, quiet, standing alone without change, moving without peril. It could be the mother of everything. Not knowing its name, I call it Tao.
LaoziA great country is like the lower outlet of a river. It is the world's meeting ground, the world's female.
