Manly Palmer Hall was a Canadian author and a mystic of outstanding wisdom. At the age of just 25 he published his magnum opus 'The Secret Teachings of All Ages', whose breadth of knowledge brought him instant recognition as a leading scholar in the fields of religion, mysticism, and the occult. 'The Lost Keys of Freemasonry' once again displays Hall's insight and erudition. Taking as his subject the Legend of Hiram Abiff, the author reveals the higher and hidden aspects of Freemasonry in beautiful and poetic prose that is accessible to Mason and non-Mason alike. The esoteric meaning of the word 'Hiram', the nature of the True Temple, the capstone of the pyramid and a host other recondite symbolism is laid bare, in a book that can be revisited again and again for its deep layers of wisdom.

This book also includes the rare "Initiates of the Flame", which uses over 40 symbolic glyphs to further elucidate the narrow path trod by masons, alchemists and mystics to that source of wisdom known variously as the 'Grail' and the 'Philosopher's Stone'.
