Same phases are used to I and II, i.e. I-(1) and II-(1), I-(2) and II-(2), I-(3) and II-(3).
The understanding direction is from (3) to (1), the application/practice direction is from (1) to (3).

fig.1. and fig.2:
The understanding direction is from (3) to (1), the application/practice direction of divergence, convergence, and sublation is from (1) to (3). As inversion of it, the thinking of (3) to (1) derives "before (1) as (0)" and the truth exists "before (1) as (0)." It is "空 (emptiness before emptiness in Buddhism," then emptiness is presence, presence is emptiness. And "before (1) as (0)" is "道 (Tao before nothingness and presence in Taoism." Then (1)~(3) as divergence and convergence are paths of (4).

The small red bead and the big water-blue bead are for example.

And this article is related to the Glass Bead Game’s meditation.

cf. Lao-tzu chapter 16.
“Resulting emptiness in limit, holding quiet seriously, all things happen together, I observe its restoration. It is things of all, each restores itself to its root. To restore itself to the root means quiet, this says to restore itself to order/life. To restore itself to order/life means ordinary, to know ordinary means well-lighted. Not to know ordinary (note: with no restoring itself), to do for no reason ill luck. To know ordinary is capacity/tolerance. Capacity/tolerance is namely public, public is namely king, king is namely providence, providence is namely Tao (principle), Tao (principle) is namely for a long time. End of life isn’t dangerous.”
