“The introduction of LSD and psychedelics into the culture produced a transformation of the entire culture, the consciousness of the culture.

“Due to a complex variety of social and historical reasons, a core feature of the Euro-American psyche is a dissociative split between spirit and nature.

                 “We are living in a very interesting time. Civilization that we call Western- techno-western civilization- is simultaneously becoming global and collapsing.”
– Ralph Metzner

As I’ve written about in the past, Ralph Metzner was a friend and teacher for over 50 years. I am honored to be speaking at a tribute event organized by his wife, Cathy Coleman. The event will be live and streamed for folks in and outside the Bay Area.
