FWIW, I also see Internal MA as something different.
Example: Qigong or Tai Chi I think are IMA. When I perform my Qigong set, I can feel the energy coursing through my body. Can I teach that to someone else? No. I can teach them the 'shell' of it, but they have to experience it for themselves.
So, I feel that the IMA is a PERSONAL experience. Can it help someone to fight? Perhaps - but this is where concepts and ideas can blur.
I can see where T might be going with all of this. The more gobble-dee-goop you give to someone to sift through, the more confusing it becomes. When you are taught to punch in a boxing gym, you glove up and start hitting...and you are 'coached' on how to hit. Given 'ideas' on how to improve the body mechanics of it all. For the mostpart - you teach yourself how to do things because if you do it right, you get results.
Anywho...this topic is maybe too far and wide. Keep it going...
