THE INVISIBLE WORLD OF THE INCAS.

The Inca flourished in the Andes Mountains of Peru in South America. They had a grand empire stretching from present-day Colombia to Chile.
Worshiping the Creator was very important to them and they held a very elaborated system of beliefs.
Their divinities actually represented a number of shifting and overlapping divine powers. They were closely linked to astronomy and tied into their everyday life as well as with their government.
Their gods occupied 3 different realms: the Sky (Hanan Pacha, the Inner Earth (Uku Pacha), the Outer Earth (Kay Pacha).
Above the Earth were the heavens. They, like the earth, were divided into 4 quarters with a very complex geography separated  by a giant cross formed by the Milky Way as it passed through its zenith. The movement of astronomical bodies through the 4 quadrants determined the Inca agricultural and ceremonial calendars.
The Earth, like the heavens, were divided into 4 quarters, whose dividing energy lines (ceques) intersected in the city of Cuzco. Each divine energy line (ceque) belonged to one of the quadrants and the care of each sacred placed (huaca) containing the divine energy (ceque) on each quadrant was assigned to a particular group of people able to deal with this type of energies. In this way the ceques helped to coordinate social relations among people, as well as to organize their agricultural and religious festivals. The ceques also served as sight lines for very specific astronomical observations. The city of Cuzco was the center of their universe.
The heavens contained a Creator-Sky-Weather complex with 3 principal components: Viracocha, the Creator; Inti, the Sun god; and Illapa, the Thunder god or Weather god.
The most important female supernatural forces were Pacha Mama, the Earth; Mama Cocha, the Sea; and Mama Quilla, the Moon.
The Incas would fear lunar eclipses as they believed that during the eclipse, an animal spirit (mountain lion or serpent) would attack Mama Quilla, trying to eat her alive. Consequently, people would attempt to scare away the animal spirit by throwing weapons, gesturing and making as much noise as possible. They believed that if the animal would achieve its aim, then the world would be left in complete darkness.
A lunar eclipse was understood as the passing of the spirit of the Moon directly behind the Earth and into its shadow. This would occurre only on the night of a Full Moon. The type and length of the lunar eclipse depended on the Moon proximity to the 2 points at which its orbit intersects the ecliptic. During a total lunar eclipse, the Earth completely blocked direct sunlight from reaching the moon. The only light reflected from the lunar surface was the one refracted by Earth's atmosphere. As sun light penetrates the Earth's atmosphere, the gaseous layer filters and refracts the rays in such a way that the green to violet wavelengths on the visible spectrum are being scattered more strongly than the red, thus giving the Moon a reddish cast.
The views of the Inca about the Afterlife was very optimistic as they believed that the protective spirits of their ancestors played an active role in the world of the living. They were able to reveal themselves through the sacred places known to them as "Huacas" and they were cared for and respected by their descendants.
The Inca Empire was moved by very strong moralistic rules, and they believed the souls of the virtuous joined the Sun in heaven. Those souls had plenty to eat and drink. These souls were able to remain connected to their descendants, and their lives continued much as they had on earth. The souls of the evildoers went to the underworld (inner Earth), a cold and barren place.

APU CON TICCI VIRACOCHA, the Creator God.

Apu Con Ticci Viracocha (lake, foam, or sea fat) was the full name of the supreme god of the Incas. He was considered the creator god and the father of all other gods. Because his name was sacred he was most often referred to by using descriptions of his various functions, these included "light" (Ilya), "beginning" (ticci), and "instructor" (Viracocha Pacayacaciq).
It was believed that human beings were actually Viracocha's 2nd attempt towards the creation of living creatures as he first created a race of giants from stone in the Age of Darkness. However, these giants proved unruly and it became necessary for Viracocha to punish them by sending a great Flood. In the legend all these giants except 2 then returned to their original stone form and several could still be seen in much later times standing imposingly at sites such as Tiahuanaco and Pucara.
Then Viracocha created men and women but this time he used clay. He also gave them such gifts as clothes, language, agriculture and the arts and then he created all the animals. Then Viracocha decided to create the sun, moon and stars and so bring light to the world. These heavenly bodies were created from islands located in the Titicaca Lake. Viracocha finished his creation and highly satisfied with his labor, he then set off to spread his civilizing knowledge around the world and for this task he dressed himself as a beggar. He was assisted in his travels by 2 sons or brothers. The god was not always well received despite the knowledge he imparted, sometimes even suffering stones thrown at him. Ending up at Manta in Ecuador, Viracocha then walked across the waters of the Pacific Ocean heading into the West but promising to return one day. In his absence lesser deities or powers were assigned the duty of looking after the interests of the human race but Viracocha was, nevertheless, always watching from afar the progress of his children.
Viracocha was an androgynous deity, created or formed by itself (hermaphrodite). In art Viracocha is often depicted as an old bearded man wearing a long white robe and supported by a staff. One of his earliest representations is the weeping statue at the ruins of Tiahuanaco, close to the Titicaca Lake, the traditional Inca site where all things were first created. Here, sculpted on the lintel of a massive gateway Viracocha holds thunderbolts in each hand and wears a crown with rays of the sun while his tears may represent rain or sorrow. This is the reason that Viracocha is related to the power of the heart and mind aiming the welfare of his people.
Viracocha was actually worshipped by the pre-Inca people of the Andes before being incorporated into the Inca pantheon. In Inca mythology Viracocha gave a headdress and battle-axe to the first Inca ruler Manco Capac and promised that the Inca would unite all the Andean people into one before them. The god's name was also assumed by the Inca known as Viracocha ruler of the Inca Empire and the god was formally worshipped from the Inca capital of Cuzco towards the 4 corners of the Inca Empire (a famous sculpture of pure gold was held in his temple), and he still is one of the most important deities venerated by the Andean people of today.
