The Way of Tao is this: It strives not, but conquers; It speaks not, but all is made clear; It summons not, but its house is crowded; It contrives not, but the design is perfect.
We hammer wood for a house, but it is the inner space that makes it liveable.
We join spokes together in a wheel, but it is the center hole that makes the wagon move. We shape clay into a pot, but it is the emptiness inside that holds whatever we want. We hammer wood for a house, but it is the inner space that makes it livable. We work with being, but non-being is what we use.
The world may be known Without leaving the house.
Cut out doors and windows for the house. The holes make it useful.
