The tao that can be told
is not the eternal Tao.
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 mystery.
Caught in desire, you see only manifestations.
Yet mystery and manifestations
arise from the same source.
This source is called darkness.’
Tao Te Ching. A New English Version, With Foreword and Notes by Stephen Mitchell, Perennial Classics, 2000
