Meant to be read with my other book, YIN, and in the light display setting. Yin / Yang: Two halves that together complete wholeness. Yin and yang are also the starting point for change. When something is whole, by definition, it's unchanging and complete. So when you split something into two halves - yin/yang, it upsets the equilibrium of wholeness. Both halves are chasing after each other as they seek a new balance with each other.
