Cusp Of Great Cycle
We are living today in the cusp of the Mayan end times, the end of a galactic day or time period spanning thousands of years. One galactic day of 25,625 years is divided into five cycles of 5,125 years.
The Great Cycle of the Mayan Long Count calendar ends on the winter solstice of 2012 A.D. Following Mayan concepts of cyclic time and World Age transitions, this is as much about beginnings as endings. In fact, it was considered by the ancient Mayans to signify the creation of a new World Age. We are almost at the end of the fifth and final 5,125 year cycle!
