There is no greater sin than desire, No greater curse than discontent, No greater misfortune than wanting something for oneself. Therefore he who knows that enough is enough will always have enough.
People in their handlings of affairs often fail when they are about to succeed. If one remains as careful at the end as he was at the beginning, there will be no failure.
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.
