Sometimes in tai chi you have to choose one aspect of practice over another to help see a path to pursue. This helps to gain exposure to new techniques and energize practice. Often, the moves themselves hint at possibilities revealed just by being attentive to changes in patterns and shapes.
In tai chi, you learn at minimum two overarching methods that make up a practice. In one you focus on what your body is doing, memorizing moves and sequences (the what); for example, giving particular attention to a single movement and the insights it reveals. You can practice it over and over until it’s internalized.
In the other method, you can focus on how you’re doing the moves, or perhaps the underlying intention of a move . . . . fertile ground for discovery. It could be looking for energy, to recognize it, get a good feel for the Qi, realize you can move it and direct where you want it to go in the body; then add good intentions for better health and well being.
In either approach, as you train perceptive ability, you can look for what attracts your attention and how it feels. Difficult to see both simultaneously at first; but if you could, the practice would be much more powerful.
