In the Great Mystic Symbolic Tetragrammaton of the Ancient Masters we have one of their deepest secrets; the discovery of what the Masters called the Sacred Four Elements, as they found that these elements enter into the constitution of everything known. Earth, Water, Air, and Fire are the elements that produce every formation, every object, every organism. The Masters then invented an appropriate symbol to embrace the Sacred Four Elements. This symbol is known to us as the Sphinx, the image of which has been found in all the lands of the ancient world, and just as far back in the night of time as it is possible for us to go. Professor Hilton Hotema again raises compelling questions regarding our physical, spiritual, and mental reactions to these Sacred Four Elements.
