<B>... Maintaining the correct curve seems to be one means of feeling the peng
energy inherent in a springy ball.
... Each curve seems to be able to express energy either on the inside or the outside.
In the palm-up curve, the inside energy seems to be like a “hugging” energy, with the jin
point expressed in the midpoint of the inside of the forearm. I feel almost a line going from the tip of my middle finger through this point and across my biceps. The outside energy (what we feel in the right arm of Press) seems to be the exact opposite.
Since you are able to feel the things that you describe, let me add something else for you to consider. Since you can "express energy" on either side of the curves, I am assuming that this describes an ability to experience the projection of energy to the opponent (or imaginary opponent in solo work). This corresponds to my other posts concerning absorb/project that you had asked about. This energy expression would correspond to "project" and, while it may feel most comfortable at the center of the forearms, it can also be expressed at any point so that it can occur at wherever the point of contact with an opponent occurs (if it is difficult to feel this projection at various places, it may help if someone lightly touches you at various points as an aid in focusing the projecting energy there - on the other hand, firm contact/resistance at various points may also help in feeling and testing this projecting energy).
Now, with the arms in the same shape, see if you can feel an absorbing energy (sticking to, and drawing the opponent into your sphere) on the opposite side of the curve from the projecting energy. This is "absorb" energy and, while it can occur separately from the projecting energy (e.g. one arm absorbing while the other arm projects), when done simultaneously it sets up the absorb/project potential (and "spin force") at a single point of contact.
If you can feel the simultaneous absorb/project, see if, while maintaining the same arm shape, you can use your intent to switch which side is absorbing and which side is projecting (of course, in application the arm shape typically does change and the arms move, I am only presenting the maintained arm shape as tool for feeling and understanding the underlying concept).
To give credit where it is due, these ideas (filtered through my own understanding combined with my numerous years studying Taijiquan) come from Sam Chin and his teachings of his family style of Chinese martial arts that he calls I Liq Ch'uan. See http://www.iliqchuan.org/
for additional information. While my understanding is perhaps rudimentary concerning I Liq Ch'uan since I only study with him at biannual workshops and weekly in a local study group, I find that Taijiquan and I Liq Ch'uan share numerous concepts, although they are often practiced/applied in quite different ways.
While some practitioners feel (with valid reasons) that training in other styles of martial arts is not good for the mastery of their chosen style, I tend not to agree. I find value in the different perspectives obtained by studying with different teachers/practitioners of the same style of Taijiquan, different styles of Taijiquan, and other styles of "internal" martial arts (and discussion boards such as this one). While I love Taijiquan, I find great value in the different approach and different interpretations and applications of related principles as found in I Liq Ch'uan. I feel that I Liq Ch'uan has enriched my understanding of Taijiquan and have presented the preceding information in that spirit.
