The Maya Calendar was the center of Maya life and their greatest achievement. The Maya Calendar's ancestral knowledge guided the Maya's existence from the moment of their birth and there was little that escaped its influence.
The Mayan Calendar is something profoundly different than just a system to mark off the passage of time. The Mayan Calendar is above all a prophetic calendar that may help us understand the past and foresee the future. It is a calendar of the Ages that describes how the progression of Heavens and Underworlds condition the human consciousness and thus the frames for our thoughts and actions within a given Age.

The Mayan Calendar is not predicting the end of the world 2012, but the start of a new era.
