Milne's two-volume text is superb and comprehensive in scope. It describes, in detail, the anatomy, physiology, and energetics of the craniosacral system. Volume One offers Milne's visionary approach to the practice of craniosacral therapy, drawing from an intelligent, diverse collection of energy work, including the dreambody work of Arnold Mindell, Eastern meditative practices, Indigenous shamanic traditions, as well as the genius discoveries by William Garner Sutherland, the patriarch of craniosacral work, and many other organic sources. Volume Two is the most complete list of craniosacral techniques in print, giving clearly written descriptions for each technique, along with technically accurate photographs. The Heart of Listening is clearly the best text for practitioners who want to expand and deepen the healing process with their clients. Volume One is also a good tool for all bodyworkers and psychotherapists, not just craniosacral therapists. The only thing that surpasses this book is the curriculum provided by the Milne Institute itself, offering excellent classes, each of which is Visionary Craniosacral Work in action. Milne describes the work as "sculpting the conscious medium" and this book is a sculpted conscious work of art. It is a valuable book to read and digest again and again, over a long period of time, savoring its wisdom and depth of experience.
