CHAPTER 11
Thirty spokes converge on a single hub;
It is the emptiness in the hole of the hub
that is the usefulness of the cart.
In manipulating the clay to make a vessel,
it is the empty space within that
is the usefulness of the vessel.
In drilling a door and window to make a room,
it is the empty part inside that
is the usefulness of the room?
Thus, possessing does have advantages,
but, it is the nothingness that will have usefulness.
