Do you have anything to support your notion that O'sensei felt that what he was doing was no longer about effectiveness?
How much first hand experience do you have with kotegaeshi from non-aikido sources?
Excuse me? I didn't say he was not about effectiveness. I said Aikido done from such a view is very effective and to me more so.
Kotegeishe is merely one example. How much experience? Much. Let's put it this way. Every non-aikido person or indeed some aikido people. That shouldn't be surprising should it for I say they should be looking after the well being of the opponent.
A new view to many. The budo of love.
Doesn't mean others are wrong for it depends on their purpose. If you can do effective technique in such a way that you at the same time are protecting the aggressor then that is I way I adhere to.
Painless nikkyo which is inescapable and yet leaves the aggressor smiling is quite an experience.
