Many of the images used in Cheng Hsin truly help to facilitate a "feeling-attention" and "body awareness" of the principles and improve function. Ball and chain, hand up you down, water drop, and standing on pilings seem to be adapted for "stand up fighting". My inquiry is about how these can be adapted to grappling or ground techniques. Have you developed others for that type of encounter?
The first 70 pages of "The Art of Effortless Power" continue to be both a challenge and a source
of inspiration. Thank you for sharing your work.
It is true that mat work or grappling on the ground present a different set of challenges. Yes, most of the images have standing in mind, but the principles involved can be done on the ground as well. I haven't invented images to serve that adjustment, but you are welcome to. Sometimes just changing the name or how you view it can be useful. I remember being told of someone who, having discovered a new image of "infinite space" beneath the ground thought they had evolved beyond me because I was stuck on waterdrop. Silly notion, isn't it? We are talking of images here, ways of developing. They are all only exercises, inventions to move people in a direction. They are not and will never be the principle itself.
Once these images are mastered at some point one can simply powerfully engage the principle without image. But I don't recommend that course until you've spent years making the images real and useful, for they offer a more concrete avenue through which to progress. But you can use whatever image serves, as long as you can make it real for yourself it will work.
