Survivor 11: Guatemala - Mayan Religion

The religion of the Mayas, like their civilization, was complex and multi-layered. Based on cyclical times of growth and destruction, with an emphasis on the growing seasons, important dates were ruled by the need for survival. The gods needed maintenance and nutrition, and when ritual bloodletting wasn't sufficient, the Mayas adopted human sacrifice. What will the Survivor contestants have to do?
