"To you it is given to know the Mysteries of the Kingdom of heaven, but to others [the people, the profane, the masses] it is not so given." - Matthew 13:11.
The foundation of the Egyptian Mysteries, which implies the Egyptian Initiation, was based on the knowledge of those who instituted the Mysteries – The Great White Brotherhood.
By giving consideration to Egypt as a land of glory, blessed with the knowledge of the Immortality of the Soul, we are brought back in a circle, as it were, to the legendary Atlantis; this for the very sound reason that the Mystery Schools, with their Philosophic Initiation, had to have a beginning.
At the time of the Nazarene there remained but one great School or Order which continued to instruct and guide Neophytes in the Greater Mysteries. This is known to us as the Essenian Priesthood. The Nazarene, like many before and after him, was Initiated, in this Order.
The Master of Galilee, like many of the Initiates of prior ages, was able to read the scroll of past ages as well as the scrolls as yet unrolled. He frequently astonished his close followers by foreseeing and forecasting their future acts.
This was notably so concerning his betrayal by Judas and his denial by Peter. Throughout the ages, it has been impossible to hide from the Exalted Initiates the most secret longings, fears and guilt of the human heart, because they are engraved upon the Subconscious where "all who see may read."
Like the inculcations of the Nazarene who taught in parables for the masses and in secret for his disciples, there were anciently the two classes of the Mysteries; the Lesser and the Greater; the inner and the outer; the parable and the Arcane.
These Mysteries could not be taught to the people. If an attempt had been made to instruct them, they would not have been able to comprehend the truth. The people believed in and demanded a personal God.

It is not possible for anyone to reveal the Mystery of the Greater Mysteries of Arcane or Philosophic Initiation. Man must accomplish that Work for himself, but we have endeavored throughout the work to reveal much of the inner spirit of this Mystery.
In the language of Sacred literature, this is the search for, and final finding of the Holy Grail; in Occult, Esoteric, or Alchemical language, it is finding the "pearl of great price"; that same pearl which the Nazarene commanded not to be cast before swine. It is the unraveling of the truth, or the spirit hidden in every human Soul. It is the finding of the kingdom of heaven, which the Nazarene promised to the few.
