Hi Its a great article but no matter what you will always get a different opinion from Iwama deshi and Hombu deshi. Its well known that most of O'Sensei's time was spent in Iwama teaching and developing Aikido and he did travel lot to his other dojos. Morihiro Saito is famous for saying that O'sensei really only taught in Iwama but demonstrated at the Hombu. im not saying this is def how it was even as an Iwama deshi. But one of the big differences in the 2 are that in Iwama the teacher was O'Sensei or Saito in the Hombu it was Mostly his son or people like Tohei who both made MASSIVE changes to the founders art that he was teaching in Iwama. Im not saying ALL these changes where bad, but these changes happened. I think its better if some of the sempai here speak of there understanding, especially the ones who spent a long time in Japan.
Even Mr. Pranin stated that Saito Sensei was NOT doing O'Sensei's Aikido, but his techniques were faithful reproductions of what O'Sensei taught. Changes happened because there appeared to be no direct attempt by O'Sensei to systematically pass on all that he knew, even to Saito Sensei. Compound that with the reality that even thought O'Sensei spent a lot of time in Iwama, he was traveling extensively. The lack of continuity of teaching in a systematic manner, over a long period of time led to people studying under him to pick up parts of what they saw, felt and were taught and they ran with it to the best of their abilities. The sharing within and outside of our community is (in my opinion) an essential component in trying to bring our own practice closer to the source. Too many heated debates occur when people try and assume that their own teachers were the one's that "got it" and that questioning them is next to heresy.
