Doesn't the titel o sensei just refer to the fact the Ueshiba morihei was the top of the pyramid?
Isn't it just kind of equivalent to something like kaiso or even soke?
I never connected the term or titel o sensei to certain teching abilities?
Isn't the background in inJapanese just an academic titel which does not necessarily imply that this sensei also is a teacher of whatever?
Okay was he a "kaiso" only because he provided the subject to be taught or did he also successfully teach it?
