check out my post "Chum-Kee seeking the bridge".that goes into what I think Ki/chi is.basically a lot of things developed over time to become one cohesive whole
But I still ask those same questions myself
.why for example are there martial arts ( usually the most effective )that never mention chi/ki
boxing,savate,Muay-Thai, greco roman wrestling??
There are things to ponder though. every week I go swimming with my family
.soon I go on vacation.and I swim in the sea.the difference is that in the local pool I can "feel the bottom".in the sea, I cannot
...not many folks realise that tactile senses such as "feeling the bottom" exist.....I do Tai-Chi, when I do pushing hands it's like swimming in a pool..when somebody attacks me with a punch ( it may be.....(and I say only may
) like swimming in the sea.
Now for myself I've identified one thing that I didn't know before.in the future maybe I'll develop it even more.but it's not magic.
I went to an Aikido Dojo
The Sensei was old and fat, professed to like Beer ( where I come from, that means you can drink a lot/frequently do/and think that anybody who doesn't is odd.
Anyway he got some young guy to make a straight down sword cut at him ( shomen).he stepped in caught the sword hand and slowly lowered it down.then he began to talk .saying about mind and intention, and how if he had been of a mind he could have thrown the guy as soon as he'd attacked.a fairly unremarkable throw
....but that the guy still had that intention in him, he still felt that that was the way he should have been thrown.....suddenly the old Sensei lifted up the guy's arm and brought it down....the same throw that he would have done but without the attacker, attacking...the guy flipped over as if he had charged in.very cool to watch
