There are several "eternal" themes associated with the secrets of mankind. And in this list, the Mayan civilization occupies, perhaps, one of the first places, steadily competing with traditional Atlantis and the pyramids of Egypt. The book is dedicated to the Mayan calendar, in which 2012 is indicated as the date of the beginning of a new era in the life of earthlings. The usual calendar date in the author's interpretation unexpectedly becomes a bridge connecting a variety of peoples, forcing everyone to think not about differences, but about spiritual unity and the future of all mankind.
