Human sacrifice Sacrifice had great importance in the social and religious aspects of Mesoamerican culture. First, it showed death transformed into the divine. Death is the consequence of a human sacrifice, but it is not the end; it is but the continuation of the cosmic cycle. Death creates life—divine energy is liberated through death and returns to the gods, who are then able to create more life. Secondly, it justifies war, since the most valuable sacrifices are obtained through conflict. The death of the warrior is the greatest sacrifice and gives the gods the energy to go about their daily activities, such as the bringing of rain. Warfare and capturing prisoners became a method of social advancement and a religious cause. Finally, it justifies the control of power by the two ruling classes, the priests and the warriors. The priests controlled the religious ideology, and the warriors supplied the sacrifices.

This was then displayed by acts, such as being struck by lightning. If someone was struck by lightning and a sacrifice was needed they would often be chosen by their population, as they believed they were chosen by the gods.

The sport had different versions in different places during the millennia, and a modern version of the game, ulama, is still played in a few places. Over 1300 ballcourts have been found throughout Mesoamerica. They vary considerably in size, but they all feature long narrow alleys with side-walls to bounce the balls against. The rules of the ballgame are not known, but it was probably similar to volleyball, where the object is to keep the ball in play. In the most well-known version of the game, the players struck the ball with their hips, though some versions used forearms or employed rackets, bats, or handstones. The ball was made of solid rubber, and weighed up to 4 kg or more, with sizes that differed greatly over time or according to the version played. While the game was played casually for simple recreation, including by children and
