Instead of a strike, consider a wrist grab. Consider using the contact point at the wrist to connect to nage's spine through his arm, and using that connection to take him down, or to immobilize him for a strike. Is that a manifestation of "harmonizing forces?" As I see it, yes, absolutely.
A strike is simply a more explosive version of the same idea.
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.
