John Holman contends that the perennial philosophy can be found at the heart of more than just the world's religions; it is to be found in all the great schools of thought, and writings of the greatest thinkers and philosophers, no matter how apparently diverse the presentation of their perceived truths. This accessible but thought-provoking book allows us to develop an understanding that the nature of reality and our potential for transcendence are at the core of all belief systems. Revolutionizing the debate on the perennial philosophy and shedding light on a number of enigmatic esoteric topics, The Return of the Perennial Philosophy will provide a crucial and rewarding spiritual context for modern times.
