Following the previous blog, a question was posted about it: “… How does Song relate to the other thing which is said regularly, that there should be ‘Peng’ in every movement? I take that to mean that Peng should be present particularly at the conclusion of every movement, and not as tension but perhaps as extension?“
Peng is possible because, although you soften the white muscle tissue (the bulk of the muscle), you don’t exactly relax the fascia, or connective tissue, you extend/stretch it, treating it like an overall flexible/stretchy body ‘stocking’.
Think of your limbs like an audio cable – there’s the core(s) of the cable, which may be any number of wires encased in different coloured plastic, and there’s an outer shield. They are all wires, but the wires on the outer shield are often meshed and can be stretched or compressed, whilst the inner wires are usually long strands without the same flexibility because they are encased in plastic, and are not usually meshed.
For the purpose of the analogy, the cable is a limb; the cores of the cable are your bulk white muscles; the shield is the stretchy, flexible fascia.
If you lift your arm in front of you as you read this, curving it so that the palm faces you at approximately chest or shoulder height, and relaxing all the muscles whilst still holding the arm in position, you are halfway there. Next you feel as though the back of the forearm is gently expanding away from you, but without involving any muscles; it’s as though the gaps between the joints have expanded, not because you have stretched them (which would involve muscles), but because they have loosened at the joints. The arm should feel heavy.
The Aikido exercise, the ‘unbendable arm’, demonstrates this concept perfectly.
If you’re not familiar with it, a brief description of it is that you place your wrist on a partner’s shoulder, and he gradually increases the pressure of his downward push on your elbow joint.
The more you tense your muscles, the harder work it becomes, but the more that you relax and loosen whilst simultaneously gently extending your arm, the harder it is for the person pushing downwards. Your arm will flex slightly, but it is more like a solid rubber tube bending under pressure than a stick snapping. A very interesting exercise.
Stretched (but not) & heavy.
The trouble is that people find it very difficult to stop using the white muscle tissue; it feels like a contradiction to relax, sink, loosen, and yet simultaneously lengthen.
It’s probably easiest to work on Song first and then add Peng, rather than the other way around, and this is where Pushing Hands or any two-person exercise comes into its own. It’s very helpful to have someone else to gently and sensitively test you by providing a small amount of resistance.
