The 2012 mark is the physical manifestation of the beginning of a new cycle of 52,000 years. This cycle is really two 26,000 cycles. The beginning of our current 52,000 year cycle saw Atlantis as a world dominating militaristic government, so self-aggrandizing and self-centered that it was brought down through it’s own self-destruction to the point that little is even left to prove it existed. (This nation raised itself above other nations from it’s own self-glorification, but is now brought down so low that it’s not even considered to have ever existed.)
The 2012 mark is also the beginning of the change-over, the beginning of a wave of consciousness coming through the earth, but taking many, many decades to fully wash through humanity and it’s generations – the generations being those in physical bodies now, and those not in physical bodies now.
2012 marks the time in astronomy whereby the Solar System passes across the galactic center. The electromagnetic pull upon our own Earth has been occurring for several decades as witnessed by some of the weather changes (and enhanced by global warming), and will culminate with electromagnetic problems which will periodically occur in 2012, affecting our own planetary electronic systems as well as any other natural or manmade aspect in our world which relies on magnetic fields for functioning or survival.
