“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.”

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 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.

¶ 6-7.
An Humble, Earnest and Affectionate Address to the Clergy (1761)
Context: All possible goodness that either can be named, or is nameless, was in God from all eternity, and must to all eternity be inseparable from him; it can be nowhere but where God is. As therefore before God created anything, it was certainly true that there was but one that was good, so it is just the same truth, after God has created innumerable hosts of blessed and holy and heavenly beings, that there is but one that is good, and that is God.
All that can be called goodness, holiness, divine tempers, heavenly affections, in the creatures, are no more their own, or the growth of their created powers, than they were their own before they were created. But all that is called divine goodness and virtue in the creature is nothing else, but the one goodness of God manifesting a birth and discovery of itself in the creature, according as its created nature is fitted to receive it. This is the unalterable state between God and the creature. Goodness for ever and ever can only belong to God, as essential to him and inseparable from him, as his own unity.

Saying 5; variant translation: More are the names of God and infinite are the forms through which He may be approached. In whatever name and form you worship Him, through them you will realize Him.

Context: Poetry is the way we help give name to the nameless so it can be thought. The farthest external horizons of our hopes and fears are cobbled by our poems, carved from the rock experiences of our daily lives.
Context: For women, then, poetry is not a luxury. It is a vital necessity of our existence. It forms the quality of the light within which we predicate our hopes and dreams toward survival and change, first made into language, then into idea, then into more tangible action. Poetry is the way we help give name to the nameless so it can be thought. The farthest external horizons of our hopes and fears are cobbled by our poems, carved from the rock experiences of our daily lives.
