“I set out wanting to compile and edit a book called, “Deep Sand – Exploring a Body Centered Approach to Psychotherapy with Children”, with chapters by various therapists who used a deep sandbox as part of their work with children and that embraced some version of a somatic oriented approach, not necessarily mine. This immediately became a problem as there were very few therapists I could find who used a deep box. (Why this is so could be the subject of another book.) So I modified the book’s theme to that of considering the idea of depth in general, i.e. the idea of embracing body, mind, psyche, instincts, all in the context of play.
