Re: Ueshiba taking Ukemi
I think the basic point Dan is making is that Aikidoka allow themselves to be thrown too much - not too easily (different problem), but too much. Dan wants to refine that 'being thrown' skill and use it to thwart the attack, to escape it, or to reverse it.
Aikidoka call the same practise kaeshi-waza, label it advanced, and so rarely practise it. It only remains advanced because it is labeled as advanced. The problem with kaeshi-waza, though, is that it too demands that tori become uke and receive full ukemi and be thrown! Mad, huh?
