Prehistoric Origin

Looked at, but cannot be seen-

    That is called the Invisible

Listen to, but cannot be heard-

    That is called the Inaudible

Grasped at, but cannot be touched-

    That is called the Intangible.

These three elude all our inquiries

And hence blend and become One.

Not by its rising, is there light,

Not by its sinking, is there darkness.

    Unceasing, continuous,

    It cannot be defined,

And reverts again to the realm of nothingess.

That is why it is called the Form of the Formless,

The Image of Nothingness.

That is why it is called the Elusive:

    Meet it and you do not see its face;

    Follow it and you do not see its back.

He who holds fast to the Tao of old

    In order to manage the affairs of Now

Is able to know the Primeval Beginnings

    Which are the continuity of Tao.
