I believe that O"Sensei is wiser than us all. Aikido is a philosophy translated into movement. When I demonstrate tenchi nage and describe that "heaven seeks heave, earth seeks earth and they meet in man (hara/tanden) the it is Morihei Ueshiba guiding the student as I simply demonstrate a technique. "Move off the line" "yield when pushed..." World over we have heard his philosophies spoken in every dojo and demonstrated in every technique. I suspect that if you introduce technique to your students with a minimum of explanation then you will provide everything that they need.
Of the students who have been taught that way, how many have even achieved the level of their teachers, much less surpassed them?
The pedagogical success of "traditional" aikido teaching methods appears to me to be mixed at best.
