Samael Aun Weor reveals the true meaning of the Apolcalypse of St John, delivering to humanity the essential clues that have been hidden for almost two thousand years. From the book: We have studied the verses of the book of Revelation (Apocalypse) in the Superior Worlds. We give the result of our investigations in this book. Much has been said and written about the Apocalypse. However, only intellectual speculations have been made and the words of various authorities have been repeated. The present work is the result of tremendous esoteric investigations that were patiently performed by us in the Superior Worlds. We have found the Apocalypse to be divided into three parts: the first we have entitled The Son of Man, the second The Sealed Book and the third The New Jerusalem. The first part teaches the Path of the Razor's Edge. The second is related with the times of the end. The third tells us of the future earth. This is a book of practical christification. This is a book of transcendental esoterism and it is absolutely practical.
