IV

The way is empty, yet use will not drain it.

Deep, it is like the ancestor of the myriad creatures.

Blunt the sharpness;

Untangle the knots;

Soften the glare;

Let your wheels move only along old ruts.

Darkly visible, it only seems as if it were there.

I know not whose son it is.

It images the forefather of God.

(Lao Tzu, Tao Te Ching)
