From the Preface:
Maha Yoga or The Upanishadic Lore in the Light of the Teachings of Bhagavan Sri Ramana is both a profound exposition of Sri Ramana’s teachings and a lucid summary of the whole Vedantic philosophy, the ancient lore of the Upanishads.
Before an aspirant embarks upon the practice of Self-enquiry, which is the cornerstone of Sri Ramana’s teachings and the essence of the Upanishadic lore, it is extremely useful — if not essential — for him to have a clear and well-founded understanding of the theoretical background upon which the practice of Self-enquiry is based, and such an understanding is possibly not made available to aspirants anywhere so clearly as in this book, which elucidates many important aspects of Sri Ramana’s teachings.
The author of this book, Sri K. Lakshmana Sarma (‘WHO’), was amply qualified to write such an exposition, because he spent more than twenty years in close association with Bhagavan Sri Ramana and he made a deep study of His teachings under His personal guidance.
MAHA YOGA is the Direct Method of finding the Truth of Ourselves, It has nothing in common with what is commonly known as ‘Yoga’, being quite simple — free from mysteries — because it is concerned with the utter Truth of our Being, which is Itself extremely simple.
MAHA YOGA frees its follower from his beliefs, not to bind him with new beliefs, but to enable him to pursue with success the Quest of the True Self, which transcends all creeds.
MAHA YOGA has been described as a process of unlearning. Its follower has to unlearn all his knowledge, because, being in relativity, it is ignorance, and therefore a hindrance. This true Yoga is the subject-matter of the Upanishads. But the Truth that is to be found by this Yoga is eternal and needs to be testified to by living witnesses from time to time.
This book starts with the very reasonable assumption that only a living Teacher can tell us the Upanishadic Truth, not the Upanishads themselves, because they are just words and little more, while the Living Teacher is an Incarnation of the Truth we seek.
The Living Teacher of our age was the Sage of Arunachala, Bhagavan Sri Ramana, of whose life a brief sketch is given in the first Chapter. His teachings are treated in this book as the primary authority, and the Upanishadic lore as next in value — as amplifying and supplementing it. The reader need not accept anything that is set forth here, unless he finds it to be in consonance with the actual teachings of the Sage.
