I generally defer to Peter G. on such matters, and he has said he doesn't see a "spiritual component of aikido inherent in the physical techniques". However, I can't help but suspect that part of the difference between ajj and aikido technique is precisely this, consciously attempted, i.e., the transformation of physical training into a...metaphor (into synesthesia?)
