What happens on and after December 21, 2012? There has been much confusion and many predictions based on the Mayan calendar. Some people think time on Earth will end, but what if there was an intact and complete resource from the ancestors that will give us the wisdom we need for the shift and an understanding of the coming era? In "2012-2021: The Dawn of the Sixth Sun," Sergio Magana (Ocelocoyotl), mystic and teacher of the ancient Toltec/Aztec lineage of Mesoamerica, discloses an in-depth understanding from a rich and uninterrupted oral tradition, the meaning of the shift from the Fifth to the Sixth Sun, the possibilities presented to humanity at this time, and ancient teachings and practices designed to support this shift. The Toltecs knew how to interpret the mathematical or universal order that governs all of existence by measuring and observing cycles of time, and the impact they had on the Earth, human consciousness, and perception.
