Carl Johan Calleman holds a Ph.D. in Physical Biology and has served as an expert on cancer for the World Health Organization. He began his studies on the Mayan calendar in 1979 and now lectures throughout the world. He is also author of Solving the Greatest Mystery of Our Time: The Mayan Calendar. He lives in Sweden.
Calleman's book is a treasure trove of history, myth, and insight into one of the most remarkable achievements in human history, the Mayan calendar. His proposal is that we moderns learn the intricacies of the calendar in order to evolve our consciousness by syncing with the planetary, galactic and universal 'high frequency evolutionary cycle.'
