Chapter 11. Usefulness of emptiness
The thirty spokes of the wheel that are joined in the center are made useful by the hollow in the middle where emptiness reigns.
Vessels made of clay are useful because of their hollowness.
Doors and windows are of use to the building because they are taken away from the wall.
Being is meritorious, but non-being is useful.
