Body of Awareness [PDF ebook] 
A Somatic and Developmental Approach to Psychotherapy

Merging scientific theory with a practical, clinical approach,
Body of Awareness explores the formation of infant movement experience and its manifest influence upon the later adult. Most significantly, it shows how the organizing principles in early development are functionally equivalent to those of the adult. It demonstrates how movement plays a critical role in a developing self-awareness for the infant and in maintaining a healthy self throughout life. In addition, a variety of case studies illustrates how infant developmental movement patterns are part of the moment-to-moment processes of the adult client and how to bring these patterns to awareness within therapy. 
Body of Awareness is intended to help therapists, new or advanced, to enhance their skills of attunement. They can do this by heightening their observations of subtle movement patterns as they emerge within the client/therapist relationship, and by respective their own developing feelings within session as essential information to the therapy process. And as developmental patterns are central to psychological functioning, a background study of movement provides the therapist with critical insight into the unfolding psychodynamic field.
