All previous systems have been sectarian, based on a traditional cosmography both gross and incorrect. Our system is based on absolute science and philosophy. We have "all in the clear light", that of Reason, because our Mysticism is based on an absolute Scepticism. But at the time of this writing I had very little mystic experience indeed, as my record shows. The Fact is that I was far, far from the Grade even of Master of the Temple. So I could not properly understand this Book; how then could I effectively promulgate it? I comprehended but dimly that it contained my Word; for the Grade of Magus then seemed to me unthinkably high above me. Also, let me say that the True Secrets of this Grade are unfathomable and awful beyond all expression; the process of initiation thereto was continuous over years, and contained the most sublime mystic experiences -- beyond any yet recorded by man -- as mere incidents in its terrific Pageant.

The "equation" is the representation of Truth by Word.
