- 1993 — "According to many ancient Mayan esoteric beliefs, Alcyone is the central star of the Pleiadian star system, and our sun is the outermost star of this system. The Mayan Great Cycle is a calendar that delineates the [26,000]-year-long orbit of our sun and solar system around Alycone. According to the latest discoveries in astronomy, our sun is moving into a "photon belt," or belt of light particles. As we move deeper and deeper into this photon belt, it would seem that we are moving into the Age of Light described in many ancient prophecies as well as by the Mayans. My latest theory about the photon belt, which combines science, astrology, esoteric sources, and secret information given to me by indigenous people, is that we cyclically travel through this belt of light for  years and then travel outside of it for about [11,000] years." -Foreword, p.
