The Lost Keys of Freemasonry is a work of esoteric philosophy by Manly P. Hall, first published in 1923.
The book presents Hall’s esoteric interpretation of Freemasonry, but he was not yet a Freemason when it first appeared in 1923; he was initiated in 1954. It discusses the ethical discipline and character traits that Hall believed a Mason should cultivate, rather than offering an official account of Masonic teaching.
Hall offers his own symbolic readings of the first three degrees of Freemasonry and the moral meanings he associates with their rituals.
The steady demand and increasing popularity of this volume, of which eighteen thousand copies have been printed since it first appeared a few years ago, have brought the present revised and rearranged edition into being.

The Mason must realize that his true initiation is a spiritual and not a physical ritual, and that his initiation into the living temple of the spiritual hierarchy regulating Freemasonry may not occur until years after he has taken the physical degree, or spiritually he may be a Grand Master before he comes into the world.
Ignorance fears all things, falling, terror-stricken before the passing wind. Superstition stands as the monument to ignorance, and before it kneel all who realize their own weakness who see in all things the strength they do not possess.
Man is given by Nature, a gift, and that gift is the privilege of labor. Through labor he learns all things.
They wander in darkness seeking light, failing to realize that the light is in the heart of the darkness.
Freemasonry is not a material thing: it is a science of the soul; it is not a creed or doctrine but a universal expression of the Divine Wisdom. The coming together of medieval guilds or even the building of Solomon’s temple as it is understood today has little, if anything, to do with the true origin of Freemasonry.
