The Renewal of Nature Awareness and Psychedelics: a conversation between old friends Ralph Metzner and Kathleen Harrison


June 17, 2016 - 7pm-9pm

Occidental Center for the Arts, 3250 Doris Murphy Court, Occidental CA 95465 (at the intersection of Graton Rd. and Bohemian Hwy.)

$35 person - Tickets.

The realms of plants and fungi provide us with life-sustaining nourishment, medicines for healing sickness, relief of pain, and delight for our senses with their color and fragrance. Mysteriously, they function as door-openers to the spirit world. They help us cleanse the lenses of perception and to know our place in the great web of life. Nature awareness deepens our experience of being alive, and the need to care of the world in which we live. How has our culture's discovery of psychedelic experience enhanced our sense of being nature and the responsibility that gift entails? What can we learn from the amazing plant teachers, the vines of visions, the mushrooms of magic? Where do we go from here?

Kathleen Harrison is an ethnobotanist, who is dedicated to studying and teaching the ways that people relate to plants, fungi, and the wisdom they can offer. She is the president and co-founder of Botanical Dimensions, a non-profit organization that has worked for 30 years to collect knowledge of medicinal and shamanic species. She teaches at BD's Ethnobotany Library in Occidental, which she curates.

Ralph Metzner, founder and president of the Green Earth Foundation, is a psychotherapist and former professor at California Institute of Integral Studies with a life-long interest in visionary plants and medicines. He is the author of Green Psychology, and editor of The Ayahuasca Experience and Sacred Mushroom of Visions.



Perspectives on the current global crisis - A conversation with Ralph Metzner
By journalist Will Shonbrun.

In this conversation we first discuss at some length the current global crisis, in light of my writing in the revised edition of The Expansion of Consciousness. We then discuss the most promising current research and application projects involving psychedelic drugs. The interview has been published on the website of Project Censored, founded by Peter Phillips.


Current State of Research on Psychedelics: Q and A from talk by Ralph at CIIS, September 2015

Topics discussed include: Cannabis prohibition, globalization of ayahuasca use, problems and prospects of current research, the value of empathogens (like MDMA) in treatment of trauma, the value of psychedelics (like psilocybin), in preparation for dying.

Heart Medicine: A True Love Story - One Couple's Quest for the Sacred Iboga Medicine & the Cure for Addiction

By Elizabeth Bast.
Drug addiction is notoriously difficult to cure or even treat. Relapse rates are discouragingly high, as are mortality rates. Since all the addictive drugs are also illegal and possession can result in incarceration - the cards are stacked against addiction therapy. Into this toxic psychosocial mix comes the legendary central African plant root Tabernanthe iboga or its semi-synthetic derivative ibogaine, a powerful entheogen used in healing and initiation ceremonies in the Bwiti  cult. Uniquely among other psychedelic plants or substances, ibogaine has the capacity to actually block addictive cravings for long enough to permit an addict to re-establish a healthy connection with the core of their being - given appropriate guidance and support.
