We join thirty spokes
to the hub of a wheel,
yet it's the center hole
that drives the chariot.
We shape clay
to birth a vessel,
yet it's the hollow within
that makes it useful.
We chisel doors and windows
to construct a room,
yet it's the inner space
that makes it livable.
Thus do we
create what is
to use what is not.
