ABOUT THE BOOK In the emerging worldview of our time, the two key paradigm revolutions are - a recognition of the multiple dimensions or worlds and recognition of the autonomy of meta-physical spirits inhabiting these many worlds. In this book, Dr. Metzner describe two multi-dimensional paradigms we have used in our entheogenic and meditative journeys of exploration and healing. One is the Tibetan Buddhist Wheel of Birth and Death - a mandala of our human journey through many lives and many worlds. Another multi-dimensional paradigm for shamanic journey practice is the World Axial Tree, with its upper, middle and lower worlds. In the last chapters, drawing on the perspectives of an expanded systems worldview and the Pythagorean octave principle, I present three divination meditations on worlds within and worlds beyond.
