Along with the Tao Te Ching, the I-Ching, or Book of Changes is one of the core texts in the context of taoism and tai chi. While in the West its true meaning has been obscured as a result of the focus on its use as a system of divination and numerology.
In China, it is recognised as a system of cosmology and philosophy that is based on the dynamic balance of opposing forces, the evolution of events as a process, and acceptance of the inevitability of change. The I-Ching provides a taxonomy that results from the observation of natural forces, and provides a series of transformative principles as a pathway to understanding a persons relationship to the world around them.
Contained within its many sections, the I-Ching includes a wide range of technical details about tai chi; these include different aspects of the yin and yang principles, to techniques for all kinds of energetic flow patterns. In addition, tai chi provides a vehicle to embody and actualize the I-Ching within the human body, mind, and spirit.
