Gaku Homma Kancho about the subject:
Speaking from experience, I can relate my feelings about being an uchideshi and uke to the Founder, Morihei Ueshiba. Perhaps only those students who actually practiced with the Founder will truly understand my feelings. As full-time students of the Founder, our respect for him was of course paramount. Especially towards the end of his life, if the Founder asked his students to "push against him as hard as they could", there was not one student among us who could do that. It was not that we were not able to physically push him, it was that we couldn't.
