Central equilibrium. This is the Chinese word I know it as—Zhong Ding. I assume readers are familiar with it. I came to understand that central equilibrium is more than alignment.
Alignment has a linear quality that we can become aware of in our bodies. It is two-dimensional, a line between two points. Equilibrium, which we can also become aware of, is orientation in relation to our environment. It is multi-dimensional. It is how we balance ourselves in response to the pressures from outside, of which there are many.
Almost every move we make is a response to some external force in our environment. The environment could be the physical environment near us or it could be a more abstract environment — distant and foreign.
Part of the release, and the relief, of letting go of things that are not essential to our well-being, which is a tai chi practice, is distinguishing between what it’s necessary to be concerned about and what is not.
We confront the overwhelming pressure from outside with great risk. We cannot defeat it, but we can relax and let it be. We don’t have to be concerned that we must respond. Yin instead of yang. Let yang take care of itself. Focus attention on yin.
So the act, as simple as it may be, of letting something go—tension, stress, anything at all—is emancipating. Our bodies respond accordingly and become satisfied, contented, rested.
