Examining the relationship between perception and events, this highly significant volume contributes several important ideas to the "bridge" between modern science and perennial wisdom teachings. Part 1, The Reign of Relativity, explores the extent of relativity's domain and the implications of its principles for spiritual development. Part 2, What is Philosophy?, gets to the heart of Paul Brunton's teachings: how to actualize reliable knowledge and durable wholeness through fulfilling, combining, and balancing the practical, intellectual, and mystical elements of the human psyche. Part 3, Mentalism, examines the power of thought and celebrates a deeper level of each individual's own mind. It focuses on the fathomless untapped power within, with which we can improve our immediate selves and consequent circumstances.
