From what I have researched they saw both good and possible bad in all aspects of their calendar. Of course within their own calendar system they divined that their whole civilization would come to an end and horrible suffering would ensue for 520 years. This did come to pass right on schedule. In 1987 their civilization or more exactly the consciousness that they espoused was scheduled to return renewed and more highly evolved. This too is being manifest as we sit here reading this information. Right on schedule too by the way. This means Bad News for those who are stuck in a controlling type of consciousness just as it did 520 years ago for the Mayan’s allowing type of consciousness.
