One

That which can be told is not the eternal
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
The two spring from the same source but differ in name
This appears as darkness
Darkness within darkness
The gate to all mystery.

(Lao Tsu)
