Greetings all,
No one else has to perceive this the way I do or agree with my perception.
It works for me. It works for everyone else I've ever taught it to.
It's not just me using it, I've shared this with other teachers (from different TCC Styles) to see how they like it and to see if their students could benefit from it.
I think if you continue to balance those two views you will have good results, such as the following:
So far there are three of us teaching this and so far it's worked out well for all of us.
I do not perceive the motion of the legs/hips to be a "rocking back and forth" type of movement.
The idea of "rocking back and forth" with the leg/hip movements conflicts with how I perceive the Essential "Practice continuously and without interruption". I perceive there would be a "break" in the energy when rocking back and forth rather than a continuous, uninterrupted flow.
I think I am explaining myself badly, because I am merely describing something I have heard Master Yang explain at the last couple of seminars I have attended. He was actually having us practice this motion for several minutes by adopting a bow stance and having us throw the body weight against the bubbling well of the front foot.
Perhaps it would be clearer to think of picking up a bow and drawing it to shoot an arrow. As you pull on the string, the bow will bend. When you release the string, the bow will not simply snap instantly back to its original position. The force that is released will actually cause the bow to snap back past its original shape for an instant and then oscillate back and forth until it comes to rest at its original shape. As I understand it, when we move weight from the back leg to the front, we need to keep the leg joints relaxed and springy (i.e., not stiff and not limp). This quality will make the arch of the legs act a little like the bow in my analogy and oscillate back and forth until they come to rest.
When I perform this movement in the form, the oscillation is mostly imperceptible from the outside, but I try to feel it on the inside. If you were not looking for it, you would definitely not see it. When, on the other hand, I throw my weight forward with some force, the oscillation is clearly visible, even if still not obvious. In this case, the front leg will absorb perhaps 90% of the force, but 10% will visibly bounce back to the rear. Then 90% of the 10% (i.e., 0.9%) will bounce back to the front. After this, it is hard to say what more is actually visible as the oscillation tamps down and reaches equilibrium.
When I think of the hips and waist, I do not think much of movement per se, but more of what is posted on this site as part of the explanation of "
Synchronize Upper and Lower Body." (By the way, I used to like the use of the word "synchronize," but now would prefer to translate the Chinese to myself as "Upper and lower follow each other" since my practice has physically changed.) That part says:
"With its root in the foot, emitting from the leg, governed by the waist, manifesting in the hands and fingers - from feet to legs to waist - complete everything in one impulse."
Rather than "emitting," I would prefer the word "developing." This explanation would then describe four actions: rooting, generating, controlling, and manifesting. I think it is important to consider these actions separately, and that this is perhaps Yin. But these actions must complete "one impulse" or "one qi," and this is perhaps Yang. Only when we see both aspects do we get one Taiji.
When we talk of body parts corresponding to the four actions, we talk of foot, leg(s), waist (lumbar area), and hands/fingers. This means we need to use the foot to root, the leg(s) to generate, the waist to control, and the hands/fingers to manifest; however, if this is all we do, how can we have "one impulse"? To my mind, it is not that the legs are the only body part that generates force, but rather that it is the key to generating force. The foot, waist, and hands also generate; however, if you go too far in that direction, you lose the specialization of functions. Similarly, it is not that the waist is the only part that controls, it is rather that it is the part that is the key to control.
When we talk about the hips, my current understanding is that the hips share characteristics of the legs and of the waist, but that they are more part of the legs. If we are addressing power generation, the hips must move before the waist so that the waist has something to control. If, however, we are talking about control, then the waist must move before the hips; otherwise, how can it lead? In either case, I think we want to avoid overloading the functions of the legs and giving nothing for the spine to do, at least according to our style. We do this, in my view, by focusing on four actions and four different parts of the body.
In terms of feel, I think we can use the horse stance we would use for simple standing meditation. We make sure to round the crotch by bending the knees and keeping them somewhat over the feet so that the pelvis feels like the top of a Roman stone arch rather than the top of a triangle. We can relax and extend the leg joints so that the muscular dynamic actually replicates some of the physics of a building arch with the pelvis acting like a keystone. An alternate way of feeling the muscular dynamic would be to feel as if the legs form a bow, with the pelvis and the tailbone acting as the central grip of the bow. Then we can relax and extend the lumbar region (i.e., the Tai Chi "waist") so that the spine from neck to tail bone can feel like an arrow that is being gently drawn down through the bow of the legs. Keep the feet flat, but the weight mostly in the balls of the feet. Your legs should feel bouncy if they are properly relaxed.
While the stance I have described is good for transferring power up the spine and is very stable, it is not good for transferring power forward or back. We know from the theory and Laozi that maximizing our abilities in one way tend to minimize them in another. To have a better compromise, our style tends to require one foot forward and one foot back at a 45 degree angle. This compromise involves some rotation of the hip joints and some twisting of the pelvis to avoid twisting the spine too much.
The result should be a posture that preserves the bow/arch of the legs and makes clear how that bow would transfer energy to the "arrow" of the spine. In that posture, the hips have two roles: they connect the two
limbs of the bow to the grip. (In my view the two legs are the limbs and the pelvis is the grip) and they increase the range of motion of the waist when needed. Although I may have described what I understand of the structure and feel of the stance, I have not described the motion needed to get there in actual usage or how the hip actually moves through time. I frankly do not understand this aspect in any detail since I focus on other aspects of practice. What I think I understand better is the motion required of the "waist."
To understand how we can and should move the waist in our style, you should imagine that the lumbar spine and the surrounding soft tissues form a ball. Make a fist with your hand, which can stand in for the ball. Now move your fist in a small circle through the [url]transverse plane[/url]. This is the plane that divides the body into upper and lower parts and is like the plane in which a
merry-go-round or carousel rotates. Now move your fist in a small circle through the
coronal plane. This is the plane that divides the body into front and back and is like the plane in which the hands of a wall clock move (imagining your chest as the clock). Now move your fist in a small circle through the
sagittal plane. This is the plane that divides the body into right and left parts and is like the plane in which a bicycle wheel moves as you ride it.
The waist, depending on the posture, will physically move in any of these three circles your fist has used, in either direction (i.e., clockwise or counterclockwise), making six possible circles. The waist can also move in any of the circles in between the six, for instance by tilting any of the circles on a diagonal. Instead of tracing a small circle with the fist, we could also have simply rotated it in place in any of the three planes, making twelve basic motions (i.e., three rotations in both directions plus the six circles). In fact, the circles can and are also combined. For instance, a typical motion our waist should make during some parts of the form is a left-right figure eight that curves through all three planes.
My understanding of our form is that we normally use combined circles that are often physically somewhat subtle. In other words, if you are not looking for them, you may not see them completely; and the longer the motion you observe, the more combinations of circles may be included. My understanding is still developing and so the following examples may not be completely correct. Examples of the transverse (carousel) circle/rotation might be the leftward or rightward motions of Rollback, Press, and Cloud Hands. Examples of the coronal (clock face) circle/rotation might be the Snake Creeps Down, the Shoulder Stroke in White Crane Spreads Wings, or the end of Ward Off left. Examples of the sagittal (bicycle wheel) circle/rotation might include Withdraw and Push and Needle at Sea Bottom. Examples of figure eight circles/rotations might include Deflect Downward, Parry, and Punch and the combined left-right movements in Cloud Hands. Rollback, and Single Whip.
The above over-long post describes my understanding of the structure of the legs and the waist movement that this allows. Since my understanding of this framework is still developing, I am sure many details are wrong or misleading; however, I think the overall thrust is correct for our style.
Take care,
