Laozi: Name

Source: Tao Te Ching, Ch. 1, as interpreted by Ursula K. LeGuin (1998)
Context: The way you can go
isn't the real way.
The name you can say
isn't the real name.
Heaven and earth
begin in the unnamed:
name's the mother
of the ten thousand things.
So the unwanting soul
sees what's hidden,
and the ever-wanting soul
sees only what it wants.
Two things, one origin,
but different in name,
whose identity is mystery.
Mystery of all mysteries!
The door to the hidden.

Variant: The Tao that can be told is not the eternal Tao;
The name that can be named is not the eternal name.
The nameless is the beginning of heaven and earth.
Source: Tao Te Ching, Ch. 1, as translated by Ch'u Ta-Kao (1904)
Also as Tao called Tao is not Tao.
Context: The Tao that can be expressed is not the eternal Tao; The name that can be defined is not the unchanging name.
Non-existence is called the antecedent of heaven and earth; Existence is the mother of all things.
From eternal non-existence, therefore, we serenely observe the mysterious beginning of the Universe; From eternal existence we clearly see the apparent distinctions.
These two are the same in source and become different when manifested.
This sameness is called profundity. Infinite profundity is the gate whence comes the beginning of all parts of the Universe.

Source: Tao Te Ching, Ch. 1, as interpreted by Stephen Mitchell (1992)
Context: The tao that can be told
is not the eternal Tao
The name that can be named
is not the eternal Name.
The unnameable 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.

Context: The tao that can be described
is not the eternal Tao.
The name that can be spoken
is not the eternal Name.
The nameless is the boundary of Heaven and Earth.
The named is the mother of creation.
Freed from desire, you can see the hidden mystery.
By having desire, you can only see what is visibly real.
Yet mystery and reality
emerge from the same source.
This source is called darkness.
Darkness born from darkness.
The beginning of all understanding.
