A recent discovery in Central America strongly suggests that all the hype and hoopla surrounding the "end" of the Mayan calendar this December was exactly that: hype and hoopla.
Archeologists have uncovered a small room that appears to have been the study of a Mayan scribe. It contains notations and numeric sequences that suggest that, at least in one view, the Mayans didn't foresee an end of time (end of the world or radical world transformation) in 2012. In fact, this particular calendar finding some of the dates extend to 3500 and perhaps even billions of years beyond that date.
Given the recency of the discovery and the preliminary nature of any conclusions drawn from it, I'm not sure that we shouldn't still find significance of some sort in the hundreds of examples of Mayan calendars found in Central and South America in the past decades, all of which appeared to end in 2012. It may be that the end of time doesn't happen this year (for those who were taking that extreme of the many available positions) but it still could point to a transformational event or experience.
The really important message here is simpler than any of that analysis, though. Transformation happens. For us to survive as a species, transformation of consciousness must continue. Spiritual evolution is not just important, it is essential. Whether there's something magic, mystical or important about December 2012 is less important than that we continue to be aware of the need for us to participate in the ever-progressing upward movement of life and consciousness.
