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.

What It Means

This is a placeholder explanation generated by the low-overhead model. It interprets "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." in the context of "Laozi, in Tao Te Ching, Ch. 1, as translated by Ch'u Ta-Kao (1904)
 • 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.
The named is the mother of ten thousand things.
Ever desireless, one can see the mystery.
Ever desiring, one can see the manifestations.
These two spring from the same source but differ in name;
this appears as darkness.
Darkness within darkness.
The gate to all mystery.
 • Tao Te Ching, Ch. 1, as translated by Gia-Fu Feng & Jane English (1972)" to mean that wisdom is timeless.
