The images in this book are a study of the moment before an action occurs, the sliver in time during which the “actor” decides, consciously or subconsciously, on his or her personal intention for that action. In that moment, guided by emotion and ethics, that person’s intention transforms potential action into physical reality. Tai chi chuan is the perfect laboratory for the study of intention. Also celebrated as as a form of moving meditation, the beauty of the motions and singular focus of experienced tai chi practitioners epitomize how intention guides action. In empty-hand forms, with weapons, or in contact with other tai chi practitioners, the projection of their intention (known as yi (pronounced “yee”)) is visible in unity with the mindfulness of the moment and the spiral elegance of their movements. I hope that you can share in the experience as you view the images.
