(13) While Hermes still walked the earth with men, he entrusted to his chosen successors the sacred Book of Thoth. This work contained the secret processes by which the regeneration of humanity was to be accomplished and also served as the key to his other writings. Nothing definite is known concerning the contents of the Book of Thoth other than that its pages were covered with strange hieroglyphic figures and symbols, which gave to those acquainted with their use unlimited power over the spirits of the air and the subterranean divinities. When certain areas of the brain are stimulated by the secret processes of the Mysteries, the consciousness of man is extended and he is permitted to behold the Immortals and enter into the presence of the superior gods. The Book of Thoth described the method whereby this stimulation was accomplished. In truth, therefore, it was the "Key to Immortality."

(14) According to legend, the Book of Thoth was kept in a golden box in the inner sanctuary of the temple. There was but one key and this was in the possession of the "Master of the Mysteries," the highest initiate of the Hermetic Arcanum. He alone knew what was written in the secret book. The Book of Thoth was lost to the ancient world with the decay of the Mysteries, but its faithful initiates carried it sealed in the sacred casket into another land. The book is still in existence and continues to lead the disciples of this age into the presence of the Immortals. No other information can be given to the world concerning it now, but the apostolic succession from the first hierophant initiated by Hermes himself remains unbroken to this day, and those who are peculiarly fitted to serve the Immortals may discover this priceless document if they will search sincerely and tirelessly for it.

(41) Aroueris, or Thoth, one of the five immortals, protected the infant Horus from the wrath of Typhon after the murder of Osiris. He also revised the ancient Egyptian calendar by increasing the year from 360 days to 365. Thoth Hermes was called "The Dog-Headed" because of his faithfulness and integrity. He is shown crowned with a solar nimbus, carrying in one hand the Crux Ansata, the symbol of eternal life, and in the other a serpent-wound staff symbolic of his dignity as counselor of the gods.

(18) Thoth Hermes Trismegistus, the founder of Egyptian learning, the Wise Man of the ancient world, gave to the priests and philosophers of antiquity the secrets which have been preserved to this day in myth and legend. These allegories and emblematic figures conceal the secret formulæ for spiritual, mental, moral, and physical regeneration commonly known as the Mystic Chemistry of the Soul (alchemy). These sublime truths were communicated to the initiates of the Mystery Schools, but were concealed from the profane. The latter, unable to understand the abstract philosophical tenets, worshiped the concrete sculptured idols which were emblematic of these secret truths. The wisdom and secrecy of Egypt are epitomized in the Sphinx, which has preserved its secret from the seekers of a hundred generations. The mysteries of Hermeticism, the great spiritual truths hidden from the world by the ignorance of the world, and the keys of the secret doctrines of the ancient philosophers, are all symbolized by the Virgin Isis. Veiled from head to foot, she reveals her wisdom only to the tried and initiated few who have earned the right to enter her sacred presence, tear from the veiled figure of Nature its shroud of obscurity, and stand face to face with the Divine Reality.
