Life expresses itself as motion. All living tissues of the body "breathe" with the motions of life, producing subtle, rhythmic impulses that can be felt under the sensitive hands of a trained therapist.

At the core of the body, the cerebrospinal fluid, which bathes and cushions the brain and spinal cord, expresses this motion in a tide-like ebb and flow involving all the surrounding tissues and bones. All bones, organs and other structures of the body follow their own particular rhythms. These help to maintain balance and integrity throughout the entire body, distributing the healing and ordering properties of the "breath of life".
