I vaguely see where you are coming from, but if striking someone is just a more explosive version of harmonising forces, doesn't pretty much everything that is effective fall under that category? What about shooting someone, or firing a missile? I'm still struggling to see where you draw the line.
The kyudo folks would probably say that they strive to make the same connection. I don't study kyudo, so I'm not going to comment. The same idea is definitely present in sword and jo work, though.
I didn't say that *all* strikes manifest aiki, just that it is *possible* to use aiki principles in strikes. And that the attacker in an aikido interaction should be practicing aiki principles.
Why does there need to be a line? Ueshiba Sensei did not invent aiki, so why can't it appear in places other than the nage side of aikido waza?
