Much of the world is wondering what's going to happen on December 21, 2012. Some think that the ancient Mayan civilization predicted the end of the world would occur on this date. However, most Mayan experts explain the Maya simply believed that a 5,126-year cycle will end and another will begin. The new cycle will represent a new beginning for civilization.

"The Pyramid of Positive Thinking," a project that's part of Cancun’s campaign to honor the Mayan calendar and the "rebirth of the world," is being constructed in the heart of Tulum, about 80 miles south of Cancun.

Tulum actually consists of 3 areas: the archaeological site, perched on a cliff overlooking the aqua-blue Caribbean waters; the hotel zone, with its white sand beaches and bohemian vibe; and the town or "pueblo," home to local modern day residents. The pyramid will be built in Tulum's pueblo and will consist of polyethylene terephthalate (PET) bottles, each with a piece of paper inside with a positive thought written on it by a visitor.

For those who won't make it to Tulum this year, positive thoughts can be submitted using the official Facebook page, Pyramid of Positive Thinking 2012. The pyramid will be 40 feet high and 40 feet wide, and will be the home of up to 700,000 positive thoughts.

The artist, Xavier de Maria y Campos, hopes that "the cosmic energy will be encrypted in the sacred geometry of the pyramid, thus enabling these thoughts to become reality." The pyramid will be constructed on a metal frame. Layers of PET bottles will be alternated with layers of soil containing seeds that will eventually grow, covering the pyramid in foliage. In time, the metal frame will biodegrade and the pyramid of foliage will remain.

Submit your positive thoughts and contribute to the newest Mayan pyramid.
