All the old documented religions record 5-6000 year cycle, and about the same since this civilization started. Christians, Mayan and Vendic between now and 200 years or so, Judaic 700 years ago. Their start basically the flood creation story, and the record of time since based on the solar system and precession with differences in accounting. http://en.wikipedia.org/wiki/Maya_calendar Becoming aware then not to be a sacrifice, or trying to determine how these cycles cause the environmental stresses that so often lead to the period of sacrifice, seems a more reasonable course of action than getting spiritually lost in the mechanics of accounting. It becomes belief? Now perhaps intent with this sort of work is good, to use the Mayan calendar event to further humanity, part of the new age religion, but the foundation he is offering is not solid enough, not based in the real world. For example little effort is made to make his claims scientific, I don't think the authors can. So the top of this belief structure may be a fog of good intent and habit, but the foundation is also of fog.
