This book presents a philosophy that includes the enlightenment experience—that embraces the wider ranges opened by the door of realization—while not excluding the contents of the more common experience. A realization in consciousness that finds no place or adequate recognition in philosophical systems proves the inadequacy of those systems. The author first briefly surveys the principal schools of modern Western philosophy in order to show how they fall short. He then presents his philosophy grounded on the authority of direct realization resulting from a transformation in consciousness.
