Being a model to the world, eternal virtue will never falter in you, and you return to the boundless.
LaoziClay is fashioned into vessels; it is on their empty hollowness that their use depends. Doors and windows are cut out to make a dwelling, and on the empty space within, its use depends. Thus, while the existence of things may be good, it is the non-existence in them that makes them serviceable.
LaoziOf all things, none does not revere the Way and honor virtue. Reverence of the Way and honoring virtue were not demanded of them, but it is in their nature.
Laozi
