His skills jumped again at Ayabe after Takeda joined him and his supposed secondary teacher was so impressed with what he saw takeda do with Aiki/ jin/ kokyu that he suggested he change the name of the art.
B: Then you did not learn aikido from the beginning. When did aikido come into being?
O'Sensei: As I said before, I went to many places seeking the true budo..Then, when I was about 30 years old, I settled in Hokkaido. On one occasion, while staying at Hisada Inn in Engaru, Kitami Province, I met a certain Sokaku Takeda Sensei of the Aizu clan. He taught Daito-ryu jujutsu. During the 30 days in which I learned from him I felt something like an inspiration. Later, I invited this teacher to my home and together with 15 or 16 of my employees became a student seeking the essence of budo.
B: Did you discover aikido while you were learning Daito-ryu under Sokaku Takeda?
O'Sensei: No. It would be more accurate to say that Takeda Sensei opened my eyes to budo.
A: Then were there any special circumstances surrounding your discovery of aikido?
O'Sensei: Yes. It happened this way. My father became critically ill in 1919. I requested leave from Takeda Sensei and set out for my home. On my way home, I was told that if one went to Ayabe near Kyoto and dedicated a prayer then any disease would be cured. So, I went there and met Onisaburo Deguchi. Afterwards, when I arrived home, I learned that my father was already dead. Even though I had met Deguchi Sensei only once, I decided to move to Ayabe with my family and I ended up staying until the latter part of the Taisho period (around 1925). Yes... at that time I was about 40 years old.
One day I was drying myself off by the well. Suddenly, a cascade of blinding golden flashes came down from the sky enveloping my body. Then immediately my body became larger and larger, attaining the size of the entire Universe. While overwhelmed by this experience I suddenly realized that one should not think of trying to win. The form of budo must be love. One should live in love. This is aikido and this is the old form of the posture in kenjutsu. After this realization I was overjoyed and could not hold back the tears.
That sounds like a clear statement that while he had learned "true budo" from Takeda, the insight that led to "aikido" as a distinct art was a direct result of his connection with Deguchi and Oomoto.
And he makes the point in a way that diminishes neither Deguchi nor Takeda, nor their respective teachings.
