We put thirty spokes to make a wheel: But it is on the hole in the center that the use of the cart hinges. We make a vessel from a lump of clay; But it is the empty space within the vessel that makes it useful. We make doors and windows for a room; But it is the empty spaces that make the room livable. Thus, while existence has advantages, It is the emptiness that makes it useful.
LaoziThe ancient Masters didn't try to educate the people, but kindly taught them to not-know. When they think that they know the answers, people are difficult to guide. When they know that they don't know, people can find their own way. If you want to learn how to govern, avoid being clever or rich. The simplest pattern is the clearest. Content with an ordinary life, you can show all people the way back to their own true nature.
Laozi
