Today I sit down with Marleen Thaler, a researcher at the University of Vienna and University of Graz. Together, we investigate the history of the transformation of Kundalini from a Hindu goddess resting at the base of the spine to her modern manifestation as a psychiatric syndrome. Along the way, we discuss the central importance of the Theosophical society, the anti-psychiatry movement of the 1970s, spiritual emergencies, and kundalini as a meeting point for religion and medicine.

In celebration of the holiday season, here's a bonus episode from the archives. In May of 2023, I sat down with Zachary Lui who is a practitioner of Chinese medicine, magic, and shamanism in the Toronto area. We started by talking about his early work with Chinese martial arts, traditional medicine, and qigong. We then got into Zac’s practice of chaos magic, diverse ritual practices, reiki, and esoteric Buddhist healing. Finally, we discussed his communication with different deities and spirits, as well as the potential dangers of working with them in his healing practice.

Today I sit down with Richard Saville-Smith, an independent scholar of madness, religion, and psychiatry. We discuss Richard’s book Acute Religious Experiences (2023), which argues that frameworks from Mad Studies can get us out from under the academy’s current habit of either pathologizing or sanitizing religious experiences. Along the way, we talk about the power struggle between psychiatry & the humanities, the influence of Queer Studies on Richard’s work, and his reinterpretation of Jesus as a madman.

Today I sit down with Willoughby Britton and Jared Lindahl, the interdisciplinary team from Brown University that is responsible for the “Varieties of Contemplative Experience” study on the challenges and adverse effects of meditation. We talk about the design, findings, and outcomes of the study, and how it opened up a new field of interdisciplinary investigation. Along the way we ask: if someone suffers harm from practicing meditation, whose fault is it? What is the ultimate cause? And who gets to interpret the experience?
