Yesterday, I was in the park, training aikido weapons with friends from several different aikido clubs. There was no dojo. We were in shoes and on hard ground, so there was no seiza. There was no kamiza with a picture of O Sensei to bow to or raise our weapons to. We did not wear gis or hakamas. Were we still training aikido, or had we invented something else?
Ueshiba had been practiced in western clothe also. He had been practiced open air. And as far as I see he had been practiced all the time not on the training sessions only. I mean that it's normal to practice somewhere out of dojo. But if the goal is to change training uniform or some rituals it will ruin aikido.
