The day after the Mayan Calendar ends should be pretty much the same as the day before. From one day to the next no radical changes in human consciousness, nor global effects should be anticipated. Think of any calendar. When the year rolls over, what happens on the planet and to people? Many celebrate, shoot guns in the air and drink too much. It will probably be pretty much the same.
Reviewing the history of the Earth, referring back one or two Mayan calendar intervals ago, nothing verifiable nor catastrophic occurred.
I did figure out this effect one night in a Chinese restaurant noticing the twelve year repetition of their calendar, while enjoying some mighty fine libation. Staring at the menu, waiting for the MSG to kick in, it occurred to me that the Mayan Calendar would be no exception. It simply rolls over and starts the time countdown again.
No where is it stated or implied that a catastrophe should occur. Is it carved in stone? No? Will it be the End of the World? No. Many will be disappointed.
Does the calendar imply a time in which consciousness can gradually evolve given the galactic motion involved? Yes. What does that have to do with Earth changes and such? Nothing. Claims of destruction are poorly researched and historically invalid. And if consciousness should shift during the ending of this epoch, well in my book, that would only be a good thing.
Why do some choose to try and scare the masses with silly doom and gloom proclamations when the intent of this calendric rollover and galactic alignment allegedly creates favorable, evolutionary changes in consciousness? I'm flummoxed. The two simply do not align, and the result is those claiming the end of life on Earth, engage in willful fear mongering.
Relax and enjoy the rollover. Do your part to invoke the greatest consciousness possible. In fact, that is all you can do. If everyone does this, guaranteed, there is no reason to worry.
