I'm quite intrigued by this discussion as well, mostly because I am exploring this concept in my active practice, actually using the, (hint, hint, Jerry) finished and unfinished links that Jerry posted for us here as reference points to guide me.
He got an e-mail from me once, that basically said, "Hi, Jerry. When are you going to finish this up, huh? Huh? When?".
He was polite in response, so I've left him be since as I'm sure he'll get around to it and I've got plenty enough to work on for now.
I've been reading and rereading as much as he has translated and have been working on trying to integrate these concepts into my forms.
I was expecially fascinated by the idea that ALL jing is peng jing, just applied in a different way. If "applied" is the proper term to use? I don't know, but it's the only one I have so I'm stuck with it.
I'd never considered that seriously before. I had heard some vague references to it, but had never actually considered it as being so until I read the article.
Very intriguing. I can see it, now, but it took me some time to begin to grasp this concept.
I also am sort of fascinated by this concept because I began to feel it for myself in Yang forms in a way that just wasn't there before, right after I attended Master Yang Jun's seminar.
As I began to integrate what he taught us into my movements, along with what Bill had taught me about rooting, I began to pay attention to a feeling of warmth and coolness that seemed centered around my mingmen point that had always been there, but never that strong.
It had previously been nebulous, so I had not paid that much attention it to. But now it was very clear, one side of my waist would feel warmer, the other cooler, depending on which side was full and which empty. Warm, full, cool, empty.
Stay with me, I have a point here but it's going to take some typing to get to it as I'm not 100% clear on this myself.
When I mentioned this to Bill at our morning class he talked me through what I was feeling. I wish I could recall exactly what he said but I don't, and suggested I follow up on it, that I was beginning to catch on to something bigger than that.
Again, he used different words, but that's how I remember it.
I haven't been to too many more classes since, it got too cold for our outdoor class and the only indoor one around here right now I keep missing for various reasons. Anyway, I haven't had the chance to talk much more about it with him, but since his talk with me I have found something more in that experience, and that is that what I was feeling was the muscles in my waist as they reached their furthest extension or contraction. I could actually feel when one side was fully extended as far as it would go. It is a very unique sensation and seems very crucial to me at this point, though I may be way off base.
But since I've never been afraid to throw a concept out there before to get beat up about...
I found it first in Single Whip. I worked quite diligently on that form, because it bothered me that I could not turn my right toe around all the way with me to it's proper position as I made the turn to the left. I always had to "drag" it with muscular force. I still do, but not as much.
Anyway, I tried to recall what the Master told us, he was very specific about the way to get that toe all the way to where you need it to go so I worked on it.
I tried and tried, for a long time, but was not succesful (as an aside, something I read in the second article that Jerry put links to has triggered something about this very point that I want to try, but that will have to wait for another time).
Finaly I let it go as momentarily unsoluble, and started paying attention to that warm and cool feeling in my back again in Single Whip as it felt stronger in that form than any other.
Really, I'm getting there, bear with me.
It was then that I figured out that those feelings were my muscles way of telling me when they were fully expanded or contracted, and further the differing degrees of that feeling indicated to me at which point I was at in between full extension and contraction. It is a great guide for where my waist is pointing in relation to my tantien and hips.
That was a big "gotcha" moment for me, and I followed up on that feeling, playing with how to make that help me somehow, since Bill told me it might.
I began to push the limits of how far my waist can turn, reaching for full extension and contraction, going for the outside edge to experiment. I concentrated more on keeping my tantien, using my navel as a rough reference point, facing in one direction while my waist turned. I began to feel that when I did this and my waist reached the furthest end of its possible rotational turn, the "stretch" I put on my waist muscles would actually begin to lift my empty leg to make a step if I wanted it to, or in the case of single whip it allowed me to reverse that feeling quite quickly to turn my waist 180 degrees back to make that "whip".
I began to feel what I can only call "energy" transmit from my waist to the muscles of my leg, and either lifting my leg to step or reversing my waist rotation at my command.
I flowed with that, and it went further. That "energy" I feel at that point is very much influenced by my "intent". If I am clearly thinking about where I want to step, my leg will simply follow that "intent" and move there, or if I am clear on how much energy I wish to rechannel through my waist and where, it goes right to that point as well.
OK, that's enough for now. I've bored everyone sufficiently with my rambling for today.
But that is where I am, and that seems to be where this discussion is going, without all the technical terms.
That is one way I've been putting "fang song" into my forms. Right or wrong, I don't know, but it has given me some questions to continue to work on and this discussion seems to be answering some of them as I keep up with it.
Thanks everyone, for your insight and knowledge.
