TAO TE CHING - Use What Does Not Exist

11. Use What Does Not Exist

Thirty spokes are united around the hub of a wheel,
but the usefulness of the wheel
depends on the space where nothing exists.
Clay is molded into a vessel,
but the usefulness of the vessel
depends on the space where nothing exists.
Doors and windows are cut out of the walls of a house,
and the usefulness of the house
depends on the space where nothing exists.

Therefore take advantage of what exists,
and use what does not exist.
