Re: Yoshinkan and "aiki"
Thank you for that more gentle response, Dan.
I think there is room for many approaches and none of them is necessarily the only correct one.
My teachers - Kinjo Asoh who was 7th dan when he died and Sadateru Arikawa who was 9th dan when he died - were both direct students of O Sensei. Following his teachings they emphasized kokyu ryoku as being the (not an) essential element of aikido - the thing we have to catch at all costs. There is no short cut - the way to get it is through many years of sincere training. Perhaps in the Yoshinkan tradition kokyu ryoku has a more specialized and limited technical meaning.
