Re: Baseline skillset
I get what you mean... but that still doesn't help in any way to advance the understanding of what we're attempting to discuss. I think it is necessary to separate the form from the substance for the purposes of discussion. To me, the substance is what we're concerned with when we're talking about "baseline" skills - the "engine" as you say. Obviously there must be some form, some structure for that transmission of power. But can I suggest, the form can be aikido waza, jujitsu waza, karate waza or whatever other form of movement, but the substance essentially remains the same?
Which is why IMO, form is irrelevant... knowing the substance brings all sorts of forms to fruition... vis a vis the techniques of aikido are limitless...?
