In my view, we can see very good cases for both ideas. Systems align with each other and they don't...
In my current understanding, they are supposed to align with each other, the reason they don't in some cases is because of parts missing in the systems. Aand that are the cases when there is very detailed in intricate framework used not allowing 'synchronicity' to fill up the missing portions of the systems. As if we use surface rules(simple stuff) then it will align by itself in most questions. But that can only be done as someone starts.
So since rules of it all are coherent and whole in theory all 3 systems(WWG, Yi Jing and Mei Hua) are suppose to align. They don't because more is needed for them to reflect fully the situations. Yet since in practice synchronicity takes over that portion that was never fully cleared out it seems.
With time some of these 'unfinished' parts become very easy to see. Hexagrams like 7.The Army for Yi Jing for example that are soo far away from the actual processes that unfold when these 2 fields interact, or more or less anything related to war... In Mei Hua is too many to count, as it takes simple Image of the interactions(Produce/Restrain etc.) and tries to apply it everywhere. In some(many) cases that is not the most important Image when some situation/hexagram unfold, so other then synchronicity it has to be fully reworked to actually map out in a valid way.
And WWG... But WWG is too intricate to be able to follow it all, so likely first may need to repair the other two.
What can be done, then. For someone that is starting - doesn't matter, there are processes that will take care of it in many cases.
Later on taht is bigger problem, although by then there are more tools one ca use.
In my view, to be able to repair that part we need to understand deeper the process. And there are 2 directions I have taken some years ago.
First is the idea the answer is first received in the nervous system. Then the rational parts of us are integrating as much of it as we allow. That is how some of the key people in the US Remote Viewing program view part of it when it first started(as it seems its mess now). And while some thought they discarded it later, I never discarded that idea, at least yet. While it may seem RV is entirely different process in its essence I view it as the same principle as this.
Other parth is that the answer is first received in the eletromagnetic forms around the body. Most likely as a synthesized Image in one of the 'Spheres'. Then is processed by the other shapes coming out of the Cube and integrated as much as we allow it, of course.
For first I focus on TCM and Inner Alchemy. For second on what we call Sacred Geometry and general electric/magnetic theories and frameworks. With the idea with time it will link to what we actually map out in clearer way and we can rework the systems so they fit into each other flawlessly, as that seems to be needed for both sides out there.
I get we aren't always fans of change, but some of the systems may need a little patching up if we want them to perform better then 'synchronicity' that works for all divination systems anyway. No way around that, in my understanding , currently.
