The Way of 12 (part 3)

To continue with the series of 12.  This gregarious number appearing all over town. 
In the introduction to the main text of The Way of Heaven: Neijing Suwen Chapters 1 and 2, by Claude Larre, it is said that:


" 9 has the power of 3.

It is effective and complete, filling the void in Heaven, Earth, and man.

10 combines the vertical with the horizontal, bringing 1 back to the head of the series.
It follows 9, adding to it the brilliance of expansion. 10 is the number of the sun and the number of man.

11 is the image of 10, expressing 1 in scattered diversity.

12 is an active whole, the doubling of the 6 junctions of the qi.
12 is also the 4 of space-time animated by 3.
It is a regulator of perfect movement.

And so it is.
