The body is the unconscious mind. Memory and experience are stored in the muscles and tissues becoming chronic holding patterns, or body armor that keeps us from feeling, being energetic, healthy and at peace. Left unaddressed these unconscious responses stored in the body become habitual recreators of patterns we prefer to move beyond. Talk therapies are extremely helpful in understanding the source of issues but do little to change health problems. Body work and energy therapies do much to relieve tension or make contact with deeper issues; however, if this material is not processed in to consciousness the necessary changes cannot be made to make healing permanent. Integrated psychotherapy work both sides of the body mind equation at the same time uniting the physical and the spiritual as an integrated whole. The definition of this work is credited to Anodea Judith and Selene Vega whose work in developing integrated psychotherapy over the last 20+ years has established validity in this approach to working with people.
