Quote by Lao Tzu ~ The Three you say...?

ch. XLII

Tao produces one
 One produces two
 Two produce three
 Three produce myriad things
 Myriad things, backed by yin and embracing yang
 Achieve harmony by integrating their energy
 What the people dislike
 Are alone, bereft, and unworthy
 But the rulers call themselves with these terms
So with all things
 Appear to take loss but benefit
 Or receive benefit but lose
 What the ancients taught
 I will also teach
 The violent one cannot have a natural death
 I will use this as the principal of all teachings.

ch. XIV

What cannot be seen is called indistinguishable.
What cannot be heard is called indistinct.
What cannot be touched is called indefinite.
The three can’t be comprehended
So they’re confused and considered one.
Its surface is not bright.
Its depths are not obscured.
Dimly seen it can’t be named
So returns to the insubstantial.
This is the shapeless shape,
The form without substance.
This is called blurred and shadowy.
Approach it you can’t see its face.
Follow it you can’t see its back.
Hold fast to the ancient Way
In order to control the present.
Knowing the source of the ancient,
Is the thread that runs through the Way.
