Well, if you make the terminology vague enough anything will fit.
There is no "internal shape"; there is "intent". The "Divine Will" as Ueshiba put it.
I've been tossing this around in my head for the last few days and I was wondering if you'd be willing to expand on this a little.
Was your remark about internal shape meant to describe the non-rigid quality (e.g. I know "posture" often implies a non-moving form) of the internal workings?
Also, what do you mean by intent here?
