The wise man, after learning something new, is afraid to learn anything more until he has put his first lesson into practice.
LaoziWhen you accurately perceive the fluidity of things, you can also begin to perceive the constancy behind them: the creative, transformative, boundless, immutable Tao.
LaoziWe 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.
Laozi
