Bodywise is based on Joseph Heller's own brand of deep-tissue bodywork, which makes the connection between life issues and natural bodily alignment, and shows how to restore the body's natural balance. The book teaches readers how to regain control and become a full-time owner of their bodies. Part One explains the way the body works, in everyday life as well as in the structures of consciousness. Part Two takes the reader on a guided tour of the Hellerwork experience.
Read a long time ago, and keep rereading parts of it as needed. It's one of the best books on the body mind connection ever. And a forerunner of Vagus Nerve/Polyvagal stuff I would say, though it doesn't state that explicitly.
