The Gnosis of The Mind 

For long I have been spending much of my time in a world of great beauty of thought and purity of feeling, created by the devotion and intelligence of one of the many theosophical fraternities of the ancient world. They called themselves disciples of Thrice-greatest Hermes, and sometimes spoke of their faith as the Religion of the Mind. They were prior to and contemporary with the origins and earliest centuries of Christianity, and they lived in Egypt. What remains of their scriptures and what can be gleaned of their endeavour has recently been made accessible in the English tongue, in such fashion as I have been able to reproduce their thought and interpret it. The labour of many months is ended; the task of reproduction is accomplished, and the echoes of the Gnosis of Thrice-greatest Hermes are audible across the centuries for English ears in fuller volume than before, and I hope in greater clarity.
