Train of thought
Just a train of thought here to check my current (and ever evolving) understanding of Aikido, would appreciate comments.
There seems to be a lot of talk about Aikido techniques not working against resistance but I thought the entire point of Aikido was to harmonise with and so use any resistance to throw uke.
Judo: Push when pulled. Pull when pushed. Aikido: Push when pulled. Turn when pushed. Resistance = uke pushing or pulling in order to stop technique; should provoke appropriate response in tori.
*SO* The point is not to execute a technique despite resistance; so if you are attempting a technique against resistance, you're not doing Aikido (failure to adopt correct solution to ukes push/pull so failure to harmonise, thus no use of the way of harmony).
So in an Aikido context any *improper* (i.e. not taken into account by Aikido thinking) resistance is executed by tori on uke by tori attempting to over power resistance by uke because no force from uke = no force to harmonise with = no technique.
So in an Aikido context there can never be any resistance because all energy expended by opponent should be used to throw uke, hence uke is at all times effectively non-resistant and complicit (albeit unconsciously) in throwing themselves.
So training to effect technique against resistance is not Aikido training. Training to use resistance is Aikido training.
Kata training should be done with no resistance thus simulating tori's use of uke's resistance to previous technique (i.e. full scenario would be, for example, Ikkyo attempted and resisted provoking use of irime nage ura but to get to the point we go straight to irime nage, zero resistance because of assumption of resistance of previously failed technique being used to execute irime nage ura) , introducing resistance simulates uke resisting their own resistance.
