The only thing Mayans said about 2012 was. . .
"It will be completed the 13th b'ak'tun.
It is 4 Ajaw 3 K'ank'in.
It will happen a seeing.
It is the display of Bolon-Yokte
in a great investiture."

Bolon-Yokte was a mayan god associated w/ creation, war, destruction, conflict, underworld, renewal. Some translations state Bolon-Yokte will descend out of the sky. How those 5 lines got twisted into 'end of world' or mass deaths I think is applying Western doomsday apocalyptic ideas to Mayan thinking.

I think the only Western correlation w/ the 2012 Mayan prophecy is Fifth Trumpet of Revelation. Revelation 9:1-11 reads of a star falling from heaven to earth & was given the key to the bottomless pit. Likewise Bolon-Yokte will descend from heaven to earth & this god is associated w/ underground (bottomless pit?). "And they had as king over them the angel of the bottomless pit, whose name in Hebrew is Abaddon, but in Greek his name is Apollo." Bolon-Yokte could also be associated w/ Abaddon since they're both spirits of destruction - Abaddon means "The Destroyer", similar to Bolon-Yokte's role.

Personally, I THINK this is all talking about a possession of a famous leader on Earth. There won't be a massive end of world event. There will be something "not right" or "off" w/ a world leader after Dec 21st, 2012.
