Since most living things depend on light in some way for survival, it is theorized that our tissues and organs live on, and in turn produce, the same energies as light. Even though light is colorless, it carries the full spectrum, where there is a frequency and vibration for each color, that relates to specific areas of the body. When the vibration and energy of a particular organ is disturbed by disease or distress, bringing that organ together with its related color, restores homeostasis. Asian medicine has shown us how meridians carry energy through our bodies, connecting to each of the organs in turn. Acupuncture is used to remove blockages in the meridians energy flow, and color is used in the same way.
