Looked at, but cannot be seen-
That is called the Invisible
Listened 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 defiend.
And reverts again to the realm of nothingness.
That is why it is called the Form of the Formless,
The Image Of Nothingess.
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.
(Lao Tzu)
