The Kallawaya cosmovision is based upon thousands of years of experiential knowledge about their environment and shared among many other communities across the High Andes. At the center of the cosmovision is the notion that humanity must live in harmony with the environment. Illness is the result of a spiritual dissonance caused by some sort disconnect between a person and his or her environment. One of the main tenets of the Kallawaya cosmovision is an ethic of reciprocity that is applied equally to people, communities, and the environment.
