My definition of Aiki is Saotome Sensei's definition of Aiki.
I can only assume that you are at shihan level since you have definitively stated that you understand and know Saotome sensei's aiki. That you must be very close to Saotome sensei and very high up in the organization that you can speak on behalf of Saotome sensei in how he defines aiki. It would be illuminating to actually understand how Saotome sensei defines aiki. Could you please define if for us?
