Tao Te Ching: Chapter 4

The Tao is empty but fills everything.

Bottomless source of all beings.

Edgeless and unconvoluted, shining with modesty, quite at home in the dust.

Hard to see but impossible to miss.

What could it be made of?

It is here before everything else.

When, through our art, we draw near to the heart of all, we cannot help bowing our heads.
