Gods and goddesses were worshiped by men and women but women felt a particular affinity for the moon and the goddesses of the earth and corn, the fertility deities. The Inca queen, the Inca's senior wife (who was usually also a sister of the Inca), was viewed as a link to the moon, queen and sister of the sun; she represented imperial authority to all women.
Every month, the Incas held a huge and public religious festival honouring one of their major gods. At the festival, there was dancing and feasting and sacrifice. The Inca understood the world as composed of three levels: Uku Pacha, the past and interior world, Kay Pacha, the present world and Hanan Pacha, the future and superior world.
Religiously, the Incas were quite tolerant of the beliefs of their conquered subjects as long as the worship did not interfere with the new obligations laid upon them by Incan religious leaders. The Incan pantheon was also forced upon them over the pre-existing deities and was considered of greater importance.
Viracocha is the supreme god. The word "Viracocha" meant something like "sea foam".The Incas believed that after God Paricia had flooded the World, Viracocha had revived it. Viracocha disguised as a traveler. He thought to have disguised himself into a traveler in rags and walked between people, observing and creating. He created the agricultural terraces (andinas) and he made the water flow.
Inti is the sun god, also called as Apu-punchau, was believed to be the ancestor of the Incas. Inti was usually represented in human form, his face potrayed as a gold disk from which rays and flames extended. Inca legend says Inti taught Manco Capac and Mama Ocllo the art of civilization and then he sent them to earth so that they can bring civilization to earth.
The Apu all possess certain superhuman physical attributes. They are true immortals who cease to age upon reaching adulthood, and they cannot die by conventional means. The apu have been worshipped by the Incas as well as other Aymaran - and quechuan- speaking peoples of the andes mountains from as early as 2000 B.C. to the sixteenth centuaryAD.
Illapa the next most powerful god was associated with rain. Illapa the thunder or weather god was envisaged as a man dressed in shinning apparel and carrying a sling and a war club. Mama Quilla is the moon goddess, goddess of marriage and the protector of women. She was the wife of Inti and the daughter of Viracocha.
Manco Capac is Pachacamac's son, celebrated for his courage. He was sent to earth to become the first king of the Incas. He taught his people how to grow plants, make weapons, work together, share resources and worship the gods.
Pillan is the God of thunder among the Araucanian people of Chile. He was usually consulted only in moments of great urgency. Urcaguary is the God of underground treasures. Pillan is represented as a snake with a deers head and a tail decorated with gold chains.
The Incans also used Divination involving a soothsayers talking with spirits often through the influence of hallucinogenic snuff to provide a trance like state and gain the ability to communicate with the other world.
