A wheel is fashioned from spokes,
Yet it is the emptiness at its hub which allows it to function.
A bowl is molded from clay,
Yet it is the hollow at its center which allows it to be used.
A house is structured from timber and stone
Yet it is the empty space within which affords it its value.
Therefore, although presence provides property,
Empty space affords utility.
