Morihei Ueshiba was born in 1883. The days of the "samurai" were long gone. Daito ryu was not a koryu then or now. And Morihei Ueshiba taught Daito ryu. He did not create a system. Kisshomaru Ueshiba and Koichi Tohei created a system.
Let me quote Sokaku Takeda about his definition of Daito ryu:
"The purpose of this art is not to be killed, not to be struck, not to be kicked, and we will not strike, will not kick, and will not kill. It is completely for self-defense. We can handle opponents expediently, utilizing their own power, through their own aggression. So even women and children can use it."
Morihei Ueshiba, once the most favored student of Sokaku Takeda, was only following his teacher in his own personal way. Morihei Ueshiba added his own personal spiritual ideology to create his aikido, but do not get confused -- he was a Daito ryu aiki man through and through. Nearly everything he did can be traced back to Sokaku Takeda.
It's been written that even Sokaku Takeda dabbled into some spiritual ideology and also did some mystical magical things.
Research reveals that a lot of "common knowledge" about aikido is really not all that accurate. More myth than truth.
I agree Mark and i always like your research, that's why i said that technicaly daito ryu and aikido are the same. My knowledge isn't inaccurate at all, but i believe that Sokaku Takeda, being a "dojo buster" himself was inconsistant with his own words about the purpose of daito ryu. But for the rest i agree, technicaly they are the same.
