I recently talked about focusing on one thing in your practice in order to develop your powers of observation, as well as perfecting the move. But I want to make clear that “whole body moves as a single movement” is the goal. That is the ultimate expression of any move. The whole body moves as the result of the parts moving in a coordinated way, in unison, and in harmony, each committing itself fully, extending fully, in all directions suffused with energy, like sunlight early in the morning. Soft yet bright, warm not hot. This is not news, but perhaps students should be reminded of it more often. It’s easy to forget. Read Taijiquan Jing. I like the version in Barbara Davis’ The Taijiquan Classics with Chen Weiming.
