The Power Within: Leon MacLaren A Memoir of His Life and Work by Dorine Tolley examines the life and legacy of one of the world's great thinkers and spiritual teachers. This very personal biography follows MacLaren from his youth through to his last days, casting a light on the teachings, the man, and the profound influence both had on thousands of supporters and adherents who were part of the movement he began: The School of Economic Science. Building on the ancient mystery schools and the legacies of the great G. I. Gurdjieff and P. D. Ouspensky, MacLaren finally met his true master HH Shantananda Saraswati. From this great spiritual teacher, MacLaren received the ancient knowledge of Advaita Vedanta, or the underlying single universal consciousness, a pillar of his future teachings. Written in masterful prose and told from the perspective of the ultimate insider, The Power Within demystifies one of the leaders of the Western mystery tradition, while painting a compelling human portrait.
