This week we sit with Bill Pfeiffer – deep ecologist, shamanic guide, and spiritual coach – whose life carried him from nuclear protests on the US East Coast to citizen diplomacy to Russia, where he first encountered Siberian shamans and became immersed, over decades and dozens of visits, in their traditions of ecstasy and communion, with realms and intelligences deeper than the world of identity and politics. A friend of Joanna Macy’s, founder of the Sacred Earth Network, and leader of hundreds of spiritual ecology workshops, Bill has dedicated his life to being a bridge between Native American & Siberian cultures, between alienated humans and the wisdom of the Earth, between heart and mind, future and past.
