In a recent reading soujurn of mine I chanced upon an article by Carl J Calleman about the Mayan Calender which has a similarity to ancient Indian/Hindu concepts of the Four Yugs (At present it's Kalyug) it's beginings and the end of the Kalyug Cycle.
The Mayan calendar describes nine different levels of evolution of consciousness, where each of the levels is developed by an era called an Underworld. The creation of the universe proceeds in a pyramidal fashion where the Nine Underworlds are built one upon the other. We may thus liken the evolution of consciousness to the climb of a cosmic pyramid that took its beginning already at the Big Bang 16 billion years ago. This climb is designed to take us to the ninth and highest level where a non-dualist perception of the world will be brought to us. All of these levels of consciousness are propelled by thirteen energies alternating in intensity to create a wave movement in which the time periods when these energies dominate consciousness are very exactly defined. The energies ultimately emanate from the Cosmic World Tree, what the Maya called Hunab-Ku, the Vikings called Yggdrasil and the Vedas Mo Lam, the central creative principle of the universe that by itself is non-physical in nature. By October 28, 2011 all of these Underworlds will be coming to their completion and so there is every reason to believe that the year 2012 will be a year when a new reality settles, a reality where the experience of linear time has come to an end and the consciousness altering cycles that are still today driving the evolution of human history will come to an end.
