The mystery of aiki
revealed in Dual spirals as an expression.
Even him bringing in Anatomy drawings to explain esoteric discussions of the Kojiki.
All to a dissinterested and unknowing audience who self admittedly didn't care.
You know....all the stuff that made it sound like he was on aikiweb 90 years later...arguing with those who were still, clearly doing something other than his art!
And of course you teach Aiki with a copy of Kojiki and anatomy drawings and expect an engaged audience?
