The Mayans of Central America had a highly developed understanding of the cycles of the sun, moon and Venus, illustrated on their famous calendar. It is common knowledge that the Mayan calendar ends on the 21st December 2012, but why is this so? The Mayans worshipped the sun as the ‘first lord’ and like many ancient cultures, held ceremonies at the winter solstice, which marked the beginning of their new year and the return of the light. At the 2012 winter solstice (21st December in the Northern Hemisphere), the sun will rise through the centre of a gap in the milky way, known to the Mayans as the sacred tree. The sacred tree was both the door to the underworld and the birth canal of the cosmic mother. At dawn on 21st December 2012, the milky way galaxy, as seen from Central America, will lie across the horizon, so at sunrise the sun (first lord) will rise from the underworld, pass through this birth canal and open the cosmic sky portal. This event only occurs once every 26,000 years, and the Mayans considered it so momentous that December 2012 marked the end of human time, as they knew it and the birth of a new age. This 26,000-year period is known to Western astrologers as the great year and is divided into 12 roughly 2000-year periods known as the age of Aries, age of Pisces, age of Aquarius, etc. As the earth turns on its axis, it wobbles slightly, causing a 1º change every 72 years in the direction to which the North Pole points. The great year is the time it takes for the North Pole to complete an entire circle – approximately 26,000 years. We are currently moving from the age of Pisces to the age of Aquarius.

The event is the Earth entering the dark rift of the Milky Way, which they knew of as the cosmic birth canal.
