Research has confirmed the critical role the body and its autonomic nervous system play in re-negotiating past trauma still held in the body. Those unresolved experiences show up as pain, emotions of anger, fear, confusion, and general body tension. Peter Levine created Somatic Experiencing®, SE, to support re-negotiation of past and present stress in the body. Each body's innate  intelligence can guide renegotiation of autonomic nervous system stress no matter when or how it originated.  These principles are foundational in my work.
