Query: A framework for understanding trauma

This is an excellent book for anyone who wants a mature view of what trauma is and how we heal from it. Peter Levine makes a compelling case that trauma is unique to the human species because our rational brains get in the way of the organism's instinctive physiological responses to life-threatening situations. In a case study near the end of the book, Levine clearly demonstrates his belief that re-exposure to traumatic circumstances as a way to heal must be gradual and at the organism's own pace. Cathartic experiences may be dramatic and lead us to believe we are helping, but in his view this approach risks deepening the traumatic symptoms. This is an excellent book, written in clear, non-clinical language that any non-professional can understand.
