This book is the first to focus on the process of sandplay and how it works. Ammann's richly-flavored account draws upon her wide knowledge of myth and folktale, yet remains a practical work, dealing systematically with the "how-to" details, the necessary role of sand pictures in enhancing the self-regulation of the psyche, the two routes from psyche to sand pictures, and the symbolic interpretation of spatial phenomena. Ammann illustrates these principles in three detailed case histories.
