The Kogi are the Indigenous people of the Sierra Nevada de Santa Marta Mountains of northern Columbia, South America. In the documentary, ‘Heart of the World: The Elder Brother’s Warning’ filmed by the BBC in 1992, the Kogi Mamas (The Enlightened Ones), who are charged with the spiritual guardianship and welfare of their people and of Nature, deliver a stark prophetic warning to the world about the destructive actions of ‘younger brother’ (modern western people) towards the Great Mother. What follows are transcribed excerpts from the Kogi Mama in the documentary.
