"Is the purification ritual complicated?"
Define "complicated". One of the rituals (so I've read) was for the ruler/priest to cut his penis with a knife and bleed on the ground which supposedly sanctified the ground with new life. Think Juan will be up for that? Complicated, no. Incredibly ignorant, well, I hate to go against the PC crowd, but YES!
Additionally, the Mayan calendar ends in 2012 (I can't remember which month). I can't say I put much stock in it. I always figured they got tired after figuring it out manually, and just said, "Oh, screw it! We won't be here anyway."
"Additionally, the Mayan calendar ends in 2012 (I can't remember which month)."
I think it was either December or November. Anyways, what was really said was that another 5,200 year period would come to a end on 2012. Basically, the Mayans believe that world history is divided into cycles of 5,200 years.
