Sigh - What evidence do you base your assertions on Takeda and Ueshiba? What basis is your claim that the"principal of non-resistance" is not part of Daito-ryu? What basis is your claim that Takeda's "high level of martial power" can easily be achieved? On what basis is your claim that Ueshiba went "well beyond the limits of Takeda and DR," except, possibly, in the moral (doctrinal) sense.
And on that last point, not to discomfit your sanctimonious perspective again, but in a PM sometime ago, I wrote to you about a number of Ueshiba's well-known moral failings, as well as another "spiritual" teacher whom you admire, who was an utter lecherous swine, and neither Ueshiba's failings nor the different failings of this other teacher are actions that we have any evidence whatsoever of Takeda doing.
Finally, in regards to your question about what is in my book regarding staffwork, you've got a lot of brass to come onto a thread ABOUT a book, and demand of the author that, because you haven't read it, he should sum it up to you.
True contractive power is made possible only to the degree that one is able to access its corresponding decontracted pole. The greater the reception, decontraction, and compassion, the greater one's power is both manifest and non-manifest. It's described as differential in physics, yang cannot exist unless its yin is equally expressed. On a psychological level if one gets caught up in one's own projected images, the static feedback begins reacting to itself instead of to that which really is thereby shutting off the full dynamic spectrum of perception and action. Resistance of the mind and body are inversely related to one's power and freedom.
