Chapter Eleven
Thirty spokes connect to the wheel’s hub;
yet, it is the center hole
that makes it useful.
Clay is shaped into a vessel;
yet, it is the emptiness within
that makes it useful.
Doors and windows are cut for a room;
yet it is the space where there is nothing
that makes it useful.
Therefore, though advantage comes from what is;
usefulness comes from what is not.
