W. Marsham Adams calls the Great Pyramid "the House of the Hidden Places"; such indeed it was, for it represented the inner sanctuary of pre-Egyptian wisdom. By the Egyptians the Great Pyramid was associated with Hermes, the god of wisdom and letters and the Divine Illuminator worshiped through the planet Mercury. Relating Hermes to the Pyramid emphasizes anew the fact that it was in reality the supreme temple of the Invisible and Supreme Deity. The Great Pyramid was not a lighthouse, an observatory, or a tomb, but the first temple of the Mysteries, the first structure erected as a repository for those secret truths which are the certain foundation of all arts and sciences.
Through the mystic passageways and chambers of the Great Pyramid passed the illumined of antiquity. They entered its portals as men; they came forth as gods. It was the place of the "second birth," the "womb of the Mysteries," and wisdom dwelt in it as God dwells in the hearts of men. Somewhere in the depths of its recesses there resided an unknown being who was called "The Initiator," or "The Illustrious One," robed in blue and gold and bearing in his hand the sevenfold key of Eternity.
This was the lion-faced hierophant, the Holy One, the Master of Masters, who never left the House of Wisdom and whom no man ever saw save he who had passed through the gates of preparation and purification. It was in these chambers that Plato--he of the broad brow---came face to face with the wisdom of the ages personified in the Master of the Hidden House.
The technique of the Mysteries was unfolded by the Sage Illuminator, the Master of the Secret House. The power to know his guardian spirit was revealed to the new initiate; the method of disentangling his material body from. his divine vehicle was explained; and to consummate the magnum opus, there was revealed the Divine Name--the secret and unutterable designation of the Supreme Deity, by the very knowledge of which man and his God are made consciously one. With the giving of the Name, the new initiate became himself a pyramid, within the chambers of whose soul numberless other human beings might also receive spiritual enlightenment.
but now The Initiator has departed the way of the wise and the house is empty. The hymns of praise no longer echo in muffled tones through the chambers; the neophyte no longer passes through the elements and wanders among the seven stars; the candidate no longer receives the "Word of Life" from the lips of the Eternal One. Nothing now remains that the eye of man can see but an empty shell--the outer symbol of an inner truth--and men call the House of God a tomb!
