The Inca worshiped the dead, ancestors, their king whom they regarded as nature and its cycles. The worship of nature and its cycles suggest that for them time and space were sacred, and the calendar was religious and each month had its own festival. The most important culture was directed to Inti the god sun who nourished the earth and man with his rays.
The most important feast was the one to the Inti, called IntipRaimi. This rich ceremony, with its nice costumes, and gold and silver offerings and decoration, was opened by the Inca emperor, his family and othre ppl. After the opening the emperor made a libation to the sun and drank chicha (a maize drink) with his family, followed by every one into the sun temple, where the imperial family made offerings of precious vessels or images to the god. The ceremony ended with eating and drinking. Another important thing was directed towards Pachama who was the mother of the earth. Wiracocha was also a very important god, and though some scholars may explain his importance due to the Christian influence, and as a god that created, claiming that his full name was "Con Ticci Wiracocha-pachaya" which means: the ancient foundation, the Lord and Instructor of the world.
Everything, from illness, to the investigation of crimes, or the definition of what how ppl die should be made to what gods, was all done by consulting the oracles, or the disposition of coca leaves, by drinking ayahuasca, or even by examining the markings on the LUNGS of a sacrificed llama.
This is very important for all the the people that die or sacrifise for the Inca Religion.
