Plant Medicine and Meditation Retreat


The first of its kind that we know of, this summer Jeff is teaming up with ceremonialist Celina De Leon and offering a retreat that explores the mutually-supporting roles of meditation and Amazonian plant medicine as tools for leading a more present and caring and sane life.

Researchers at Johns Hopkins University have tentatively found that subjects who combined meditation with psilocybin showed “stronger effects in trait [outcome] measures such as gratitude, life meaning, interpersonal closeness, and forgiveness” compared to the non-meditating control group. Conversely, in another study, a few long-term meditators who were given psilocybin reported it benefited both their sitting practices and their practice in life, increasing loving-kindness and curiosity and overall helping them become more flexible in their relationship to meditation.

There is anecdotal evidence to suggest this may be true for other plant-based medicines as well. In July 2016, plant ceremonialist Celina de Leon and I are co-hosting a special retreat in Costa Rica that will explore the potentially mutually supportive roles of Amazonian plant medicine and mindfulness meditation. Participants will learn about the dynamics of each practice – how healing and “purification” happen, how perspectives loosen and change, and much more. Rough exploration schedule here. Meditation instruction and practice will occur throughout the retreat, to help participants prepare for ceremony, to help with anchoring and integration, and to ensure the process of insight and growth continues after participants return home. The week is designed to be both enlightening and restorative, with individual consultations, sharing circles, nature excursions, Ayurvedic treatments, art therapy, and yoga all woven into the program
