Why is the Tai Chi symbol going in the anti-clockwise direction?
The Tai Chi symbol has 2 forms – earlier heaven and later heaven. For a complete explanation read the Shambhala Guide to Taoism (Shambhala Guides) by Eva Wong. In summary, the earlier heaven Tai Chi symbol is used by the Taoist Tai Chi Society to represent the goal of “returning to the Source”. In short, “the source” represents a state of body and mind that is conducive for good health and the act of “returning” to it represents the practices in reaching the goal of longevity.
