The ancient Mayan civilization had one of the most advanced understandings of astronomy and their calendar reflected this sophistication. But the Mayan calendar is not simply keyed to the movement of planetary bodies. It functions as a metaphysical map of the evolution of consciousness and records how time flows spiritually as well as materially - providing a new science of time. The calendar is associated with nine creation cycles which represent nine levels of consciousness or Underworlds on the Mayan cosmic pyramid. Through empirical research Calleman shows how this pyramidal structure of consciousness development can explain things as disparate as the common origin of world religions and the modern complaint that time seems to be moving faster. Time in fact is speeding up as we transition from the materialist Planetary Underworld of time that governs us to day to a new and higher frequency of consciousness - the Galactic Underworld - in preparation for the final Universal level of conscious enlightenment. Calleman reveals how the Mayan calendar is a spiritual device that enables a greater understanding of the nature of conscious evolution throughout human history and the concrete steps we can take to align ourselves with this cosmic evolution toward enlightenment.
