For the record, I am in no way agreeing or conceding that O Sensei or Doshu blurred or distorted the historical record. A photo was altered for reasons that we can only speculate about.
I am not endorsing the views of this Sensei in the interview. I am merely clarifying what he said.
The quotes below about the changes only happening after O Sensei died should be read in conjunction with other statements in the interview, including the direct rejection of the idea that Doshu was responsible for any split and the acknowledgement that O Sensei and Takeda had a falling out. This falling out happened before O Sensei or Takeda Sensei died.
I could easily point to various posts by certain people in which they did accuse Doshu of taking the art in a direction that the founder did not approve of or otherwise was unaware of. Thus Ledyard Sensei's long post rejecting the statements that I am referring to. In the meantime I believe that reading the interview in it's entirety demonstrates that Gauren Sensei recognizes that Aikido changed before O Sensei died. He claims that O Sensei continued to have more Daito Ru in him than those who followed but does not deny that O Sensei changed the art.
I have no issue with the idea that Morihei took an active part in the blurring of the historic record - I don't think that I recall anyone here doing so either.
He does, however, quite clearly implicate Kisshomaru as well:
Later, when O Sensei died, an issue concerning the stabilisation and transmission of Aikido as an autonomous art came up. One way to ensure this was to cut the historical ties with Daito-ryu Aiki-jujutsu.
Nagare, "the dynamic utilisation of the aggressor's intentions" is the typical form of Aikido that developed after the death of the founder; this is the particularity of what we call modern Aikido.
Personally, I always thought that people often underestimated Kisshomaru's abilities - probably in contrast to his father. I felt him quite a few times, and he felt plenty good to me at the time.
And BTW, it's still
not "Taku Muso Aiki".
