Today's selection comes to us from The Complete Works of Lao Tzu by Hua-Ching Ni.
Thirty spokes together make a wheel for a cart
It is the empty space in the center
which enables it to be used.
Mold clay into a vessel;
it is the emptiness within
that creates the usefulness of the vessel.
Cut out doors and windows in a house;
it is the empty space inside
that creates the usefulness of the house.
Thus, what we have may be something unsubstantial,
But its usefulness lies in the unoccupied, empty space.
The substance of your body is enlivened
by maintaining the part of you that is unoccupied.
