Accept disgrace willingly... Accept being unimportant... Surrender yourself humbly; then you can be trusted to care for all things. Love the world as your own self; then you can truly care for all things.
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.
Clay is fashioned into vessels; it is on their empty hollowness that their use depends. Doors and windows are cut out to make a dwelling, and on the empty space within, its use depends. Thus, while the existence of things may be good, it is the non-existence in them that makes them serviceable.
