I don't discount what you write above. And most things are energy-based. Physics tells us so.
I don't view that energy as the "ki" from martial arts. If that "ki" was "life energy" which is all around us all the time, why did Ueshiba state at specific moments in training to "fill yourself with ki"? Wouldn't you already be filled with life energy? We want more life energy? It's like saying stand in six directions meaning stand in hanmi at a 60 degree angle.
As we've come to see with Chris Li's translations, Ueshiba meant some fairly specific martial training methods/concepts. I don't think this example of fill yourself with ki would be any different, but it isn't the overall "ki" definition everyone gives.
Actually, I wonder if some of what you stated above can't be tied into a collective consciousness theory.
Good point, and what is the glue that binds that collective together? maybe an application of non-martial ki?
