The thirty spokes unite in the one nave; but it is on the empty space (for the axle), that the use of the wheel depends. Clay is fashioned into vessels; but it is on their empty hollowness, that their use depends. The door and windows are cut out (from the walls) to form an apartment; but it is on the empty space (within), that its use depends. Therefore, what has a (positive) existence serves for profitable adaptation, and what has not that for (actual) usefulness.

Thirty spokes join in one hub
In its emptiness, there is the function of a vehicle
Mix clay to create a container
In its emptiness, there is the function of a container
Cut open doors and windows to create a room
In its emptiness, there is the function of a room
Therefore, that which exists is used to create benefit
That which is empty is used to create functionality

Thirty spokes meet at a nave;
Because of the hole we may use the wheel.
Clay is moulded into a vessel;
Because of the hollow we may use the cup.
Walls are built around a hearth;
Because of the doors we may use the house.
Thus tools come from what exists,
But use from what does not.
