This week, I speak with Professor David Yaden,  Assistant Professor at Johns Hopkins University school of Medicine, on the topic of self-transcendence and psychedelic-assisted therapy. We discuss what psychedelic-assisted therapy is, its importance for mental health conditions, and a focus on the set and setting of clinical trials. Professor Yaden defines the meaning of transcendence and the importance of spiritual and mystical experiences. We conclude by discussing limitations in the field, and his new book: Varieties of Spiritual Experience.  To buy the book: Varieties of Spiritual Experience: https://www.amazon.com/Varieties-Spiritual-Experience-Research-Perspectives/dp/019066567X Website: https://davidbryceyaden.com/ Image: Alex Grey
