Yes, my post might seem contradictory. I shall clarify...
I know nothing about the power, really, just a few things I have tried to read. I just really know what "Internal Power" is not. The only thing that I have been able to discern from the literature that I have found, is that is has to do with "not-usual" body mechanics. But, I have found no clear explanations, i.e., ones that don't talk about "life force," or "energy flowing through the body along meridians" "pushing willpower through the Dan Tian," etc.
I need to hear a good, old-fashioned bio-physical explanation of what it is and what I must do to express it. Something like, "flex your this to make that happen." I find it difficult to imagine that, over the thousands of years that "internal power" has, apparently, been used in martial arts, no one has just spoken about it simply, like the phrase, "lift your hand to here." And, no, I don't accept that "Internal Power" is an esoteric subject. After all, we're really only talking about body motion and I don't think that that Taichiquan, Baguazhan or Hsing-I stylists possess body parts that I don't. Therefore, I should be able to, at the very least, conceive of how their techniques are performed.
