There is a trick to doing taiji, a simple one really; yet most people apply it only after struggling to get it in the beginning. But it is crucial to master this trick in order to get the most benefit out of doing taiji. The trick is … to focus the mind on a single thing and hold your attention there for an extended period of time. That’s the first part. The second part is to then move from there. Initiate movement from that point and allow the energy (qi) to flow through the whole body, animating its parts: bones, joints, ligaments, tendons, muscles, organs and so on. Of course, the third part is to retain the memory of how you do this after you leave taiji class, then practice it in the quiet of your special place for meditation and movement practice.
