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 pur-sue with success the Quest of the True Self, which transcends the creeds. Maha Yoga has been described as a process of un-learning. 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 by living witnesses from time to time. Maha Yoga assumes that the Truth can be told only be a living Teacher and not by the Upanishads themselves. The author has taken the sage of Arunchala, Bhagvan Sri Ramana’s teachings as the primary authority for setting forth the concepts of Maha Yoga.
