THE INCREDIBLE POWER OF RECIPROCITY IN THE INCAN EMPIRE

The TAHUANTINSUYU meaning "Four Parts Together" or "Land of the Four Quarters" reigned in South America stretching as far North as southern Colombia and Ecuador, including Peru and Bolivia as well as northwestern Argentine and northern Chile.
FIVE PRINCIPLES defined the Andean way of life: To Love (Munay), To Learn, Know and Remember (Yachay), To Work (Llan'kay), Respect Life (Kawsay), and Reciprocity (Ayni).
Among all of them, Reciprocity (Ayni) was regarded as the most important principle, as it provided the BACKBONE OF LIFE.  It was understood as an exchange of energy between humans, nature, and the universe.
By observation they gave this lesson: a tree that is watered by humans uses this water to convert carbon dioxide into oxygen and glucose. The oxygen is used by humans to perform respiration and survive, and some glucose may eventually find its way into products that humans use such as fruits.  In return, humans convert oxygen back to carbon dioxide for use by the tree, as well as planting seeds that the tree produced to develop more trees. Also it will rip rewards to the simple act of watering a tree as it will provide shade, act as barriers for the wind, as soil anchors, and much more.
The cosmos was perceived  dual  and hierarchical with a variety of opposing forces jostling in position through on-going action. Their world view was animistic. The idea that life and will were intrinsically connected with spiritual forces acting in the three levels of reality in which humans were part of, was the central point of their religion.
The Supreme Deity or Creator God (Viracocha) was remote from the people. The Sun and the Moon were treated as two opposing forces that acted in the realm where humans lived. A three part balance was the aim of all principles. The Supreme Deity was the only one able to be transferred from one realm to the other. The other two were understood as twin forces able to gain balance and complementing each other as long as human behavior accepted the laws governing such balance.
The Five Principles were followed and the reciprocity they enjoyed was seen through the way of life they had during the glorious time of the Incan Empire.
Certain aspects of these principles are still done by the remnant left that still live up in the mountains.
