Roger Gilchrist leads a centering practice that explores dynamic equilibrium. This principle in Craniosacral Biodynamics can be found in stillness and in action. It is the action of dynamic equilibrium that keeps the living system in balance. Rhythmic balanced interchange is a function of dynamic equilibrium. Roger explores dynamic equilibrium via the structure of the body, the movement of energy, the tide of primary respiration, and the equipoise of the field.
