thank you for the link. I think I am getting stuck on semantics. Ueshiba talks of standing on the floating bridge of heaven but what he describes is more like after Izanagi and Izanami have descended to earth and are circling the pole, procreating and creating (takemusu, if you will). I was strongly reminded of this by the youtube video of Mifune performing judo kata that David Orange posted on the Way of the cross thread.
(see third and fourth forms)
As I say, I think I am getting caught up in semantics and looking for distinctions that aren't there, and Ueshiba is referring to the whole story (or that this second part of the story is a metaphorical repitition of the first).
