"Georg Nicolaus' writing leaps beyond mere comparison of systems of Depth Psychology and spirituality, establishing a foundation for a true Spiritual Psychology. Depth psychology has long needed a balancing of the dark interior sufferings of the psyche with the soul’s openness to the truth of Divine radiance. Here it is!" - Robert Sardello, author of Silence: The Mystery of Wholeness and Director of The School of Spiritual Psychology, USA"Jung and Berdyaev were self-consciously modern thinkers with very different backgrounds: Swiss Protestantism and Russian Orthodoxy. Central to them both was the notion of the person, not as a given, but as a creative opportunity. Dr Nicolaus’ thoughtful book is the first to bring their ideas into dialogue." - Andrew Louth, Professor of Patristic and Byzantine Studies, Durham University, UK
