Re: Ki Usage and O-Sensei: A Question
There are many who believe that Osensei's "demonstrations" of ki were considered to be parlor tricks. Many uchideshi claim that daily training had little resemblence to the surviving cinematography of Osensei and his feats. "Aiki" is one of the core tenants of Daito Ryu, at least as described by Kondo sensei, so if aiki was invented by Osensei he must have taught it back to Takeda sensei. That seems unlikely to me.
