I understand all that and I have never gainsaid it. My point was that at core is the Yin-Yang cosmology and the attention on following the laws of nature in "harmony". That cosmology is also the basis for many of the other things you mentioned, BTW. Peace and Harmony is good. It feels good. Ueshiba, though, didn't come up with the concept and the fact that if feels good, nor was he the first person to include it in his martial teachings, by any means.
Incidentally, I'm not trying to come across as a nihilist. My approach is more in line with dispassion being a correct approach as opposed to passionate defense of strongly-held beliefs somehow being a proof of the "spiritual". Martially, you're probably well-read enough to know that I'm on firm ground with that correspondence.
