It's one of the most intense-sounding, indigenous rites of passage you'll ever ever hear about.

The Kogi tribe in the Brazilian rainforest is one of the last tribes on earth to maintain their pre-Columbian customs.

The Kogi choose their priests at birth.

The child is then sent to a dark cave for the first 6-9 years of their life.

When they emerge, they have an absolutely pure connection to nature and spirit.

It’s hard to believe…and it’s true.
