On the state level, religion was controlled by the Tlatoani and the high priests governing the main temples in the ceremonial precinct of the Aztec capital of Tenochtitlan . This level involved the large monthly festivals and a number of specific rituals centered around the ruler dynasty and attempting to stabilize both the political and cosmic systems, these rituals were the ones that involved a sacrifice of humans . For example, on the feast of Huey Tozoztli, the ruler himself ascended Mount Tlaloc and engaged in autosacrifice in order to petition the rains . Throughout society, each level had their own rituals and deities and played their part in the larger rituals of the community . For example, the class of Pochteca merchants were involved in the feast Tlaxochimaco where the merchant deity would be celebrated and slaves bought on specific slave markets by long - distance traders would be sacrificed . On the feast of Ochpaniztli, all commoners participated in sweeping the streets, and they also undertook ritual bathing . The most spectacular ritual was the New Fire ceremony which took place every 52 years and involved every citizen of the Aztec realm, during this commoners would destroy house utensils, quench all fires and receive new fire from the bonfire on top of Mt . Huixachtlan, lit on the chest of a sacrificed person by the high priests . </P> <P> In the Nahuatl language, the word for priest was tlamacazqui meaning "giver of things"--the main responsibility of the priesthood was to make sure that the gods were given their due in the form of offerings, ceremonies and sacrifices . </P>
