I'm not sure where this comment is supposed to lead. Specifically, I was talking about the point at which the exercise of defining the aiki body becomes a regular part of your body movements. And if I am wrong, it will be neither the first time nor last time. In addition to my comment about aiki being a perishable skill, I would also add that it is a quantitative skill (i.e., you can have more than me). There is a photo of O Sensei standing with a gentleman (Kuki Takaharu). In the photo, O Sensei has clearly been pulled off balance; notable because it is one of the few photos or videos that show O Sensei being compromised by his partner. I think a solid piece of evidence that even O Sensei had peers in aiki. Amusing because you can tell by his face the opportunity was not planned. A great demonstration of aiki with no tatami in sight.
