Highest good is like water. Because water excels in benefiting the myriad creatures without contending with them and settles where none would like to be, it comes closest to the way.
As it acts in the world, the Tao is like the bending of a bow. The top is bent downward; the bottom is bent up. It adjusts excess and deficiency so that there is perfect balance.
Thirty spokes meet in the hub,
but the empty space between them
is the essence of the wheel.
Pots are formed from clay,
but the empty space within it
is the essence of the pot.
Walls with windows and doors
form the house,
but the empty space within it
is the essence of the home.
