The mountains of the Sierra Nevada de Santa Marta of Colombia are the sacred ancestral lands of Indigenous Peoples: the Kogi, Arhuaco, Wiwa, and Kankuamo. Together, they number over 30,000 people. The inhabitants share the belief that they are the guardians of the heart of the world. Their spiritual leaders are called Mamos. The Mamo is charged with maintaining the natural order of the world through songs, meditations and ritual offerings. Through deep meditation, ritual offerings, songs, and prayers, the Mamos follow the law of caring for the Sierra Nevada to maintain the equilibrium of life for the sacred mountains and the entire world. They are concerned that non-Indigenous people are plundering and dismembering the Earth.
