Third Rebirth of the Sun
The ancient Vedic folks observed nature like very few of us do. Under the blazing sun during the day; the morbid but cool starlit sky in the night was one of the few things that they could observe besides contending the other extremes of nature - climate, germs and animals. The dominant Sun; the easiest to observe appears in most doctrines - Vedic, Egyptian, Mayan … to name a few. The Sun appears in our everyday lives at a predestined time and rejuvenates life. Metaphorically, it sets and stays in the underworld to be re-born the next day. Sunrise occurs so frequently that we have taken it for granted. If it were not to reappear (be reborn) the next day, life on earth and the surrounding planets would cease - there is little to debate the celebration of the Sun's appearance (rebirth) everyday. The Vedic seers observed the rebirth of the Sun in many ways through prayers and meditations.
The Sun is at it's powerful in spring and it faces a severe decline in fall (autumn). The very fear that the shorter days of the fall would continue and eventually perish all life on Earth was a matter of contention and the phenomenon clearly shown in earlier astrological and astronomical scripts. The rebirth of the Sun (Mitra) around December 21st was of utmost importance - it showed the increasing longer days which would culminate in spring when Sun was at it's closest - life on this planet could continue undeterred.
From the cities and vantage points where one can observe the night sky, the Seers could witness the Center of the Milky Way - the Center of the Galaxy to which the Sun would eventually belong to someday. The massive belt of the Galaxy was metaphorically observed as the pregnant belly of the mother of all creation - Aditi or perhaps Vishnunabhi and the dark rift around it the Galactic Birth Canal. Every year the Sun as it had done many thousands of years back moves into the Dark Rift and reappears - the third rebirth.
In 1998, the population on Earth witnessed the first of the conjunct phenomenons - the positioning of the Sun at the farthest from the center of the galaxy. The lowest this stellar system could stoop to - the beginning of the end of the Kali Yuga.
In 2012, during winter solstice, the Sun will have its triple rebirth on one single day - a day to rejoice a day marking the end of Kali Yuga declinations and the beginning of Kali Yuga rising to the Golden Period. The Mayan seers perhaps realized it was hard to predict a triple Sun rebirth on a single day and therefore decided not to pursue the Calendar. For the many mortals who would witness the Galactic changes to our Sun - the life giver, it will be a moment to remember.
