Does the book describes binary mathematics (via the ying and yang) and how it can be used to describe basically all complexity and complex interactions ? Have you read that bit? I heard Alan Watts mention it and I thought it was interesting.

From Tao #42

>The ten thousand things carry yin and embrace yang.

>They achieve harmony by combining these forces.

...

>For one gains by losing.

>And loses by gaining.

From Tao #28

>Knowing light and staying dark, be a pattern to the world.

>Being the world's pattern of eternal unerring power is to go back again to boundlessness.
