While working with Shishida to translate his findings on Takeshita's diary and the meanings of Aiki it was made quite clear to me that the concept of "Aiki is love" did not exist with Ueshiba M. and his cohorts in the 1920's. The "Aiki-nage" of Ueshiba's Daito Ryu or 1920's Aioi-Ryu was quite a different concept to what many Aikidoka refer to as "Tenchi nage" today. Ueshiba referred to Aiki Nage in his 1931 book "Budo Practice" as - "the skill to instantly break balance at will in order to stop an opponent's attack". The book then shows clearly that the opponent is thrown AFTER Aiki is applied, indicating that it is a separate element from the throw itself.
In the 1920s Aiki was understood and taught as a technical element of Ueshiba's training. Later on it became a slogan for universal love. I think that throughout this thread the two definitions have been used side by side as if referring to the same thing. They're not.
Just my 2 cents.
This is -of course- well in keeping with his then current training in Daito ryu
- where aiki is a separate discussion from technique. For similarities in dairies and notes; you had Sagawa's father enter in his own journal in 1913 "Sensei says to apply aiki-here."
There are prescribed methods for applying aiki in different ways, but aiki emanates from aiki in the body as the first requirement. Also mentioned in Sagawa's own book.
This is just more reasons why people like Stan, Ellis and myself say you really cannot discuss Aikido without discussing Daito ryu. The cornerstone requirement of "aiki" is foundational and inseperable between the arts; it is what happens after
aiki is applied, and the depth of the abiity to generate aiki that is the defining difference. But even now, in the 21st century, we see so many in aikido really striving to go back to the older methods of application (which I still feel is mistake and a digression from the path of aiki) if it is done without training the body -for aiki.
