Could you explain this for Nikyo as an example, and how it was done to you?[/b]
Since I can't do it, it's really hard for me to explain. But, in the case of nikyo (the version with uke's hand on nage's shoulder), it really felt like nage sort of "sucked" me in (suikomi) toward his center as he was applying the nikyo. Rather than the usual sort of impact one would feet in the wrist, I just sort of felt my center being drawn and down. It sort of felt like a"wave" that went through me starting at my hand, on through my arm, and affecting my center that drew me in.
Maybe some day I'll be able to do something resembling this. Maybe then I'll be able to describe it better.
Good discussion. Really made me think...
