Maya Cosmogenesis 2012: The True Meaning of the Maya Calendar End-Date, by John Major Jenkins and Terence McKenna. Why did the Maya choose the date of 21 December 2012 to mark the end-time of their long-count calendar? And why mark the (northern) winter solstice? Studying the star charts, independent scholar/author John Major Jenkins noted that a very rare alignment in the precessional cycle will occur on the December solstice in 2012, when the sun conjuncts the centre of our Milky Way galaxy. Seasonal alignments occur once every 6,450 years, but this December solstice of 2012 occurs once every 25,800 years! Jenkins surmised that the Maya, like many other ancient cultures, were aware of precessional cycles, but it was no coincidence that they marked this date. Indeed, as he discovered, it was central to their cosmology, mythology and calendrics, as was the idea of galactic centre as the source of life. The Maya even had a glyph to present the black hole at galactic centre--the existence of which has only recently been confirmed by astronomers.In his expansive new book, Maya Cosmogenesis 2012, Jenkins explains how the Maya revered the end-time as a zero point, entered through galactic centre and involving an energy field-effect reversal and rebirth into a new World Age. In explaining his thesis, he takes us on a heady trip through Maya shamanic rites, the origin and development of the long-count calendar at the sacred site of Izapan, the galactic geometry and symbolism of the ball court, and much more. Jenkins' finds not only extend our understanding of Maya cosmology; they have great significance for humanity at the evolutionary crossroads.
