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)
