Episode 22: Kathleen Harrison, Cannabis and Spirituality
This episode of the MAPS Podcast is taken from the Psychedelic Science 2017 conference in Oakland, CA. The talk is by the legendary and luminous Kathleen Harrison, M.A. and is entitled "Cannabis and Spirituality - Exploring the Plant Human Spirit Relationship". Kat's decades of work as an ethnobotanist focussed largely on the deeply inter-connected history and relationship between human beings and cannabis. A relationship existing not just in a cultural setting but also a spiritual one. This talk explores the nuances of the relationship, cultural appropriation in respect to psychedelic mysticsm and a holistic blueprint for how one might approach spirituality with cannabis as a guide. Kathleen (Kat) Harrison, M.A. is an ethnobotanist who loves to explore the relationship between plants, mushrooms and human beings—particularly in the realms that are often hidden: cultural beliefs, personification of species, rituals of healing and initiation, vision-seeking modalities, and artistic creations that illustrate the plant-human relationship. She also studies and teaches the deep history of humans in nature, encompassing both before and since the advent of agriculture. Kathleen founded Botanical Dimensions in 1985, with her then-husband, the late Terence McKenna. Visit www.botanicaldimensions.org
