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?

Together we explore “emergent phenomena,” or the spiritual, mystical, magical, energetic, and psychedelic possibilities at the deep end of human experience. Along the way, we discuss dark nights of the soul, ontological fruit salad, brain scans of peak meditation states, and warning labels on spiritual practice.

Today I sit down with Miguel Farias, an experimental psychologist and researcher of religion, spirituality, and cognition. Together we try to get to the bottom of whether meditation is actually good for you through a comparison of Miguel's research on the adverse effects of meditation with my research on Asian notions of meditation sickness. Along the way, we discuss the limitations of modern Western understandings of consciousness, and explore whether we can develop a more expansive, multifaceted understanding of altered states both pleasant and unpleasant.

In today's episode, we are launching the new season with the tables turned. Producer Lan Li takes over the microphone to interview me about spirit healing and related practices. Lan has been trying to ask me these questions for the last two years, but I've continued to put them off. Now it's finally time to put some things on the record and clear the air. So in this episode, we dive right in to questions like do spirits exist? Are mystical experiences real? What are the best talismans for healers? We're also going to talk about different kinds of possession and the benefits of holding more than one ontological perspective at the same time.

I hope you enjoy the conversation, and please subscribe to The Black Beryl wherever you get your podcasts. We also want to invite everyone to check out blackberyl.substack.com. Our episodes are going to continue to be free as always, but we now have paid subscriptions where we can make exclusive resources available to members for a small fee.

Today I sit down with Volker Scheid, an interdisciplinary scholar and longtime practitioner of Chinese medicine. Together, we take an intellectual deep dive into his thoughts about the importance of blurring disciplinary boundaries and how “meta-practice” can make sense of the many different kinds of Chinese medicines. Along the way, Volker and I discuss the commensurability of Chinese medicine and biomedicine, the importance of connecting the self with the ten thousand things, and how premodern ideas can be the basis of a new politics for modern times.
