The Inner Palace investigates Wisdom Traditions from around the world and the sacred realities they reveal. These include teachings with Buddhist, Christian, Hindu, Jewish, Muslim, and Taoist roots. Its discussions are grounded in primary sources from these traditions, with support from some 1500 books. These rich teachings are presented gradually, in a conversational tone, invoking a sense of intimacy and personal warmth, gently encouraging inner reflection. The Inner Palace takes us into the underlying experiences that sages of these traditions have invited us to contemplate. There are valuable tools here for describing spiritual paths and mystical experiences, placing them in the context of a more inclusive vision that reflects some of the highest aspirations and heart-felt insights of mankind. A work interweaving philosophy, the phenomenology of religion, the history of ideas, the psychology of spirituality, and transpersonal psychotherapy, it is a treasury of resources for teachers and students and for scholars and spiritual seekers alike.
