First published in 1962, this book is the follow-up to author Mouni Sadhu's three previous works: "In Days of Great Peace," "Concentration" and "Samadhi." A noted Occultist and Mystic of the first half of the Twentieth Century, Sadhu tried many paths on the route to self-realization, and is thus uniquely qualified to relate the truths in this book. Steeped in the Hermetic schools which abounded at the turn of the 19th century, then embracing the teachings of Sri Ramana Maharshi and Vichara-yet never forgetting his Catholic faith-Mouni Sadhu successfully advances our mental synthesis and leads us to the door of True Self. "The occultist who seeks to find answers to everything by means of mental understanding may find some assistance on this path in the following chapters. On the other hand, spiritually minded persons may discover confirmation of their own inner longings, when they read about the reality and possibility of the Ultimate Realization and about the necessary steps toward it. "It is in this hope that I have collected here a number of essays that have been partly published during the past seven years, rounding them out with some new chapters especially written for the purpose of the present book. "It is essentially a series of essays on various aspects of occultism and the spiritual experience."
