Others have mentioned throughout the thread that Takeda taught O Sensei Aiki, I simply pointed out it wasn't true. He taught him a high level of martial power, but that can easily be achieved without one of Aiki's primary principles of non-resistance. O Sensei went well beyond the limits of Takeda and DR.
The videos of O Sensei preserve a good amount of his staff work, which anyone can see. Does your book describe the details and forms of his staff art as well?
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.
