The tradition of the shamans Yurupari of southeastern Colombia, Intangible Heritage of Humanity by UNESCO:
The “Traditional knowledge Yurupari Jaguars management of the world” is a system of sacred knowledge that was given to the ancient wises to care for the land and human life. That is the cultural heritage of many ethnic groups living along the river Pira Parana in the south-eastern Colombia, in the department of Vaupés.
It focuses on traditional knowledge aimed at maintaining the relationship between humans and nature, and contains ancient wisdom useful for land management. This body of knowledge is a whole culture that continues and is manifested in ritual ceremonies, social behavior and economic practices, ecological and cosmological.
The anthropologist Gerardo Reichel-Dolmatoff wrote a book about this tradition called ‘Yuruparí: studies of an Amazonian foundation myth’. When he first visited the Vaupes’ jungles in the 70’s he thought that cultural was about to disappear because the missionaries were working very hard to bring ‘civilization’ into that jungle.
Fortunately now days the body of knowledge of Yurupari Jaguars is recognized as endangered cultural heritage by Unesco.
More about the Pirá Paraná’s traditional knowledge:
"Ancestral Knowledge is within us all. Ancestral Knowledge is an ancient way of knowing, of interacting with your environment that is place-based. It is through listening and remembering that lessons of life come. Ancestral Knowledge is in your speech, how you laugh at a joke, how you choose to response to your grandmother or to your brother. Ancestral Knowledge is in your community and in all the colors of the seasons. Plant and animal relatives carry ancient cosmic energies that are transferred to us through Ancestral Knowledge determining cultural identity."

It is believed that Mata Hari was transmitting secret spy messages with mudras, while dancing, half naked. None will ever verify it, I guess.
