Bob Makransky is a systems analyst, computer programmer, and professional astrologer. For the past 42 years he has lived on a farm in highland Guatemala, where he studied Mayan astrology and shamanism with his teacher don Abel Yat Saquib until don Abel's death in 2009.

Bob's books are written for intelligent, thoughtful astrologers and magicians, who are seeking true information and insight rather than mindless fluff.

Bob became interested in magic at Micky Russo's Spiritualist Church in San Francisco in the 60's, but it wasn't until twenty years later that he began channeling spirits himself. He moved to Guatemala in the early 70's and started a farm which operates on principles akin to Rudolf Steiner's Biodynamics, but with a Mayan slant. He became involved with local Mayan priests because of Mayan calendar software he had written, which they had adopted; and he was given a ritual to invoke Mayan spirits himself.
