It is important to understand that the "hype" surrounding 2012, actually commenced in 1978 and still has until 2017 to complete.
We are truly living in a wonderful era, that was foretold document by the ancient Priest to which is secretly found encoded within the cards.
Due to the procession of the equinoxes, we are aware that every 2000 years or so that we enter a new zodiac - next being Aquarius. This constitutes being the "earth cross" formed by the constellations, Taurus, Leo. Scorpio (Eagle) and Aquarius and is basically in line with the suns ecliptic. It is movable primarily due to the wobble of earth's poles and rotates through the zodiac, over period of 26,250 years or so.
The galactic cross encircles the Milky Way and is fixed, that is, it crosses the ecliptic at two specific points.
Click out here if you do not want to know more, for it is here is where you will never see the cards the same way ever again.
I'll only explain one facet in this writeup.
The High Priestess represents the nexus at the vernal equinox, situated for argument's sake, in Taurus (hence her head dress). The ancients depicted the Milky Way in a number of symbols. The ouroboros and the wreath are two examples of this circular wonder, but they also symbolised this "pillar of smoke" by columns, such as Jachin and Boas. The High Priestess symbolises the sun's transit over the Milky Way precisely at the vernal equinox, as indicated by the star cluster Pleiades (the 7 pomegranaets draped to her rear) and the "white rift" as indicated by Jachin.
This is a well know astrological fact and was encoded within the cards for posterity. This earth cross is the exact cross to which the Christians have us believe Jesus transcended to God upon. This actually happened as depicted within the "MOON" card.
The true meaning behind the moon card is mind blowing.
