The Void

Thursday Afternoon Dao

Thirty spokes will converge
In the hub of a wheel;
But the use of the cart
Will depend on the part
Of the hub that is void.

With a wall all around A clay bowl is molded;
But the use of the bowl
Will depend on the part
Of the bowl that is void.

Cut out windows and doors
In the house as you build;
But the use of the house
Will depend on the space
In the walls that is void.

So advantage is had
From whatever is there;
But usefulness rises
From whatever is not.
