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 Source of Heaven and Earth;
The named is the Mother of Ten Thousand Things.
Desireless, one may behold the mystery;
Desiring, one may see the manifestations.
Though one in origin,
They emerge with distinct names.
Both are mysteries –
Depth within depth –
The threshold of all secrets.
