Well, actually, they are pretty specific to the training of the body. I already mentioned what motion and stillness refer to generally; in a training context you use various held kokyu forces to train the body in standing (stillness trains motion)... "Aiki" as Shioda did it is the obverse of motion returning to stillness. The other 3 "polarities" are different things you physically do with the body. For instance, someone previously (in a different thread) mentioned how he learned part of an exercise where they raise the hands over the and then pull down and in the arms and hands tightly making fists... I knew right away that he was describing the outward appearance of one of the "contraction-extension" trainings that go with traditonal martial qigongs. In other words, these 4 polarities (8 powers) are pointing out the 4 major components of martial qigong training.
