It would suggest to me that if Uke regains his/her balance Tori has not unbalanced Uke fully in the first place.If Uke is totally unbalanced how does he /she recover?Cheers, Joe.
I don't have time to discuss it in deep right know, will come back later. Only quick overview - if uke is not passive, he can regain his balance even after being totally unbalanced. That happens because nage is always making errors.
With traditional aikido practice we may have impression that every technique is successful -- Uke always helps Nage more or less. But when Uke become very active, suddenly all delusions of grandeur go away and we are faced with painful reality -- our techniques always sucks.
