How to Practice Mayan Astrology: The Tzolkin Calendar and Your Life Path, by Bruce Scofield and Barry C. Orr. How to Practice Mayan Astrology presents a contemporary guide to one of the most sophisticated astrological systems ever developed. Like other ancient peoples, the Maya looked to the cycles of the planets as markers of time and designators of order. The predictable cycles they observed became codified in the Mayan calendar and astrological system as a way of organizing the seeming chaos of human life. Mayan astrology is based on 20 named days that are cycled 13 times to create a 260-day calendar, the Tzolkin. The authors explain the symbolism, logic, and meaning of the 20 day-signs; how these signs reflect 260 possible personality types; and how they can be used for divination. They also explain the important role of the Four Directions and the planet Venus in one’s personality matrix and life issues. Included are extensive, easy-to-use tables of Mayan astrological data, allowing readers to determine their day-signs, to see how these signs are also influenced by the cycle of the Night Lords and the 13-day trecena, and to cast their own horoscopes.Bruce Scofield is the author of seven books on astrology, including Day-Signs: Native American Astrology from Ancient Mexico and Signs of the Time: An Introduction to Mesoamerican Astrology. He has been a practicing astrologer for more than 36 years and lives in Amherst, Massachusetts. Barry C. Orr is a software developer who designed some of the early computer programs used by technical astrologers.
