This seminal text by the founder of sandplay therapy offers clinicians and students a foundational account of the workings and practice of this therapy. Through simple but elegant narratives of actual casework, Kalff articulates her theoretical understanding of how sandplay therapy heals and transforms the psyche. Dr. Martin Kalff, the author's son, provides a new introduction in which he shares original historical material about his mother and her development of the sandplay therapy method. A comprehensive index and tables of illustrations and references are included for ease of study and understanding.
