Anyway, afterwards, we did some weird spiritual thing: spreading arms going up and folding hands above your head. Letting hands go down bofore your center and make a cocoon with the hands. Close the eyes and shake the cocoon-hands softly.
After doing that for a half minute, making circular motions with that cocoon, around your body at the level of your center, like it's floating on water.
not spiritual thing. it's an internal power practice thing, if you know the details. same goes for funakogi undo. you can go through the motions which most folks do or work with some of the internal experts, and the information they will tell you on those things would make your head explodes.
