The name that can be named
is not the eternal Name.
The unnamable is the eternally real.
Naming is the origin
of all particular things.
Free from desire, you realize the mystery.
Caught in desire, you see only the manifestations.
Yet mystery and manifestations
arise from the same source.
This source is called darkness.
Darkness within darkness.
The gateway to all understanding.

The Way is infinitely high, unfathomably deep. Enclosing heaven and earth, receiving from the formless, it produces a stream running deep and wide without overflowing. Opaque, it uses gradual clarification by stillness. When it is applied, it is infinite and has no day or night. It is restrained but can expand, it is dark but can illumine; it is flexible but can be firm. It absorbs the negative and emits the positive, thus displaying the lights of the sun, moon and stars.
