In this week’s episode Robert Tindall and David Shearer speak with Joanna about: the pre-Columbian Amazonian high civilizations that left their lands more fertile than when they arose; reintroducing ancestral wisdom in the 21st century; biochar, charcoal used for agricultural regeneration; the suppression of the indigenous ways of consciousness in Europe;  bridging the scientific and the indigenous views of the world;  biochar, biomimicry of fire;  “shamanic archaeology”; re-encountering the animistic, multidimensional mode of perception; a vision about the missed possibilities of the meeting of two cultures and the future; the Amazon women of the Amazon.

Robert Tindall, MA, is a classical guitarist, a long-time student of Zen Buddhism, an inveterate traveler, and the author of “The Jaguar that Roams the Mind” and “The Shamanic Odyssey:Homer, Tolkien, and the Visionary Experience”. Tindall works as a professor of literature, and divides his time between the San Francisco Bay Area and Peru. He leads journeys into the Amazon rainforest and to the Andean archaeological site of Chavín de Huántar to encounter the healing traditions there.
