Tao defined is not the constant Tao.

No name names its eternal name.

The unnamable is the origin of heaven and earth;

named, it is the mother of the ten thousand things.

Emptied of desire, we see the mystery;

filled with desire, we see the manifestation of things.

Two names emerge from a single origin,

and both are called mysterious,

and the mystery itself is the gateway to perception.
