The seed of mystery lies in muddy water. How can I perceive this mystery? Water becomes clear through stillness. How can I become still? By flowing with the stream.
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
