THE NATURE OF THE INCA POWER.

The Inca religion were a pastoral kind. They believed that people had special connections with the supernatural world. The Creator God, Viracocha,  was above everything and had the biggest power. He was believed to be the supreme God of creation, history, and eternity, who personally ruled the World and intervened regularly with human affairs.
The Incas distinguished themselves  from the predecessors cultures by ruling their empire through a religious and administrative apparatus that respected and accepted the local customs of conquered people, rather than by might alone. That improvements in infrastructure, and religious tolerance gave them enough power to succeed as a culture and placing themselves as the head of an empire that unified a humongous amount of people from different cultures, living in the highlands, forest, and lowlands of the Andes.
The Incas strongly believed in the afterlife. It was believed that a transcedental realm existed in which an essential part or essence of an individual's identity continued to exist after the death of the physical vessel or body. The essential aspect of the individual that survived after death was the most important one because it conferred the personal identity of the individual during his life time in the world of the living.
The Incas encompassed the belief that there was no separation between the spiritual and the material world and souls existed not only in humans, but also in animals, plants, rocks, geographic features such as mountains, rivers, or other entities of the natural environment, including thunder and wind.
The Incas were able to understand the difference between the energies of persons and things, as the vital principle of the phenomena of life, and the diseases were traced to spiritual causes.
They Incas cared deeply for their dead, out of respect, loyalty, and continuity of the family lineage, whom they embalmed, mummified and placed into tombs, and looked after them. These included a sense of continuity between this life and the next and the mummification was a way to preserve the corpse of the deceased to ensure the continuity of its life. That is why tombs were treated as houses in the Hereafter and so they were carefully constructed and decorated.
After the death of the Inca, the priests class would come to his resting place and talk to the dead ruler. The supreme priest had he ability to communicate with the souls of the dead rulers through shamanic ways and believed that they possessed the ability to influence the fortune of living, and they often acted as messengers between the worlds. This type of communication was done during the time in which the soul of the death person was expecting to journey until reach his final destination.
The shamanic practice involved the practitioner reaching altered states of consciousness in order to perceive and interact with the frequencies of the spiritual world and channeled these transcendental energies into this world in a controlled way. They had access to, and influence in, the world of the benevolent and malevolent spirits. These entities included deities, demons, spirits, and ghosts, and were of varying importance, according to the powers they had and the position they occupied in the unseen world.
The Incas were very aware of the existence of these entities and the power that they had over the living world. To enjoy a fruitful life all the forces had to be maintained in balance in order to maintain peace in all the levels of existency.
The belief in a Hereafter in the pre-Inca cultures in the Andes goes back a long time since the first settlers appeared in the Andes and held an unique way of living. They represented the scenes of their everyday life in the textiles, ornaments, ceramics and other artifacts left in the elaborated tombs of their leaders.
The body of their leaders were treated as if they were alive given the fact that their source of power were still bound to them and there were laws applied between worlds in relation to the reception of that specific power over the hands of the leaders chosen to be invested with it.
Even to the peasant, the continuity of life in the unseen world was a major concern because they knew that everything had a role to fulfill in the world of the living and that role secured the continuity of life in an energy form in the eternal world.
