This guy ties it all together rather nicely IMHO.. The economy / economic problems, the middle east, the book of Revelation / the Tree of Life, what *I* call "the evolution of humanity". All packaged nicely with the "waves" of the Mayan calendar.
This first link gives a good overview of what this guy is talking about and includes most all of the topics mentioned above.. It was written MONDAY, MAY 18, 2009
"This is the true end date of the Mayan calendar, according to Carl Calleman, who happens to be one of my main gurus when it comes to Mayan cosmology."
October 28, 2011
And here is an updated link written July 13, 2011
"A couple of months ago I expressed my expectation that the Fifth day, beginning on July 31, 2011, will bring a global economic collapse, which would be the start of this end time scenario."
The beginning of the Fourth night of the Ninth Wave
of the Mayan calendar system
All we need added for this to be complete is Nibiru and the Anunnaki and here is Wikipedia on Zecharia Sitchin, Nibiru and the Anunnaki
Fair and balanced, you decide ;)
