I don't think Chris's blogs -like Ellis's book- was ever meant to conclusively prove anything, but rather to highlight facts and spur research.
There is a way to take it a step further:
- Detail the writings and sayings of Morihei Ueshiba for what they were; direct quotes of Chinese internal principles.
- Then directly correlate or establish those same saying to the internal work in the Chinese arts.
- Then demonstrate their use and what they actually mean in aikido.
This has never been done before by anyone capable of the work. I have not read of, met or seen any
Japanese Shihan capable of the fullness of this endeavor. In fact due to the requirements inherent in the work, I think it is best left to westerners and it is heavily in process.
