“Two towering figures thread their way through this book: St Teresa of Avila, the sixteenth century Spanish Carmelite saint, writer and reformer and C. G. Jung, the founder of modern depth psychology. Through sharing fifteen key papers, chapters and talks written over nearly twenty-five years, the author draws on their writings to focus on, and explore, the interface and relationship between the Christian mystical tradition and Jungian, depth psychology. Jung saw the human psyche as “by nature religious” and made this insight a principal focus of his explorations. In this regard, the book aims to explore an essentially depth approach to spirituality and numinosity relevant for todays’ largely post-religious situation. Jungian depth psychology, with all its own richness, can serve as an essential psychological foundation for, and bridge to, the Christian mystical tradition.
