Hi All -
Louis - Thanks for that. Wow. The Wu quote pretty much sums up what I've come to realize as double weighting especially during solo practice. Very interesting translations as well. "Two bodies, one mind" - I'll be stealing this if you don't mind.
Audi - Since my slant on this principle is "non-opposition of force" my relating Taijiquan to Aikido is very much the same in this regard. I wasn't referring to similarities "technique" so much as internal "principle". Moving off the line of attack is of course a very good example of "non-opposition of force" principle. The ...CONNECTING...and ...BINDING that you wrote about is another. That's exactly my point. Connect centers (2 weights) and bind them (into 1 weight) to which I would add - ...lead the center (1 mind, 2 bodies) into emptiness or the pavement or a wall, etc.
The demonstration Yang Jun did was an example of what I am talking about. When he stood there rooted and felt like a "lump" he may have connected centers but it still created 2 centers (of gravity). Like 2 bookshelves leaning on each other. When he connected centers then moved allowing the push to go into "nothing" he connected centers then moved the opponent's as part of his own leading the push into emptiness.
I've seen some Taiji stylists do the same thing Yang Jun did in the first example but were not able to lead their opponent's force into emptiness. This "stall", mentally or physically (thanks for that one David), stops or disrupts the flow needed to move the opponents center as part of one's own thereby giving the opponent the opportunity to take over control of the centers. If the opponent isn't very skilled either it will probably end up in a "force-on-force" shove & tug match.
Double Push - again I'll approach this from a "non-opposition of force" perspective. If you push the opponent at the wrong angle allowing him to root (weight) your push or he still has good gravitational alignment (weight) providing him an opportunity to defend and counter, you are "double weighting".
If you push from a superior angle (one in which he can't root or "weight" himself) and/or you have destroyed the opponent's gravitational alignment and root (weight) before you attack you are not "double-weighting" due to the fact that his "weight" (center of gravity) has been destroyed while your's remains intact. In fact that is good Taiji isn't it? Push them when you are at your most stable and they are getting ready to fall anyway, right?
Good Training - Erik
