Question - "How does Jhana meditation simplify experience to facilitate insight and cognitive flexibility?"
John Vervaeke is joined by Mark Miller, Rick Repetti, to explore the intersection of predictive processing, relevance realization, and embodied cognition in contemplative practices. They introduce PhD candidate Jonas Mago, who discusses his research on Jhana meditation and its impact on cognitive flexibility and insight. The conversation touches on contrasting Jhana practices with charismatic Christian traditions such as speaking in tongues. They also explore how Jhana states temporarily reduce the complexity of perception, allowing practitioners to observe the construction and deconstruction of their experiential models. The neuroscientific evidence provided, such as changes in brain responses during these states, adds depth to this exploration, illustrating how such simplification can lead to profound insights.
Mark Miller, a philosopher and cognitive scientist, holds a senior research fellowship at Monash University's Center for Consciousness and Contemplative Studies in Australia, with affiliations at the University of Toronto and Hokkaido University in Japan. His work, which dives into the interplay between human thought, technology's impact on well-being, and human-computer interaction, is at the forefront of integrating cognitive neuroscience with philosophical inquiry.
Rick Repetti is Professor of Philosophy at Kingsborough Community College, CUNY, USA. He is the author of The Counterfactual Theory of Free Will (2010), as well as several articles on Buddhism, meditation, free will, and philosophy of religion.
Jonas Mago is a cognitive neuroscientist and wellbeing aficionado, deeply invested in understanding the cognitive and neurobiological mechanisms underlying human flourishing. His research explores contemplative practices designed to cultivate wholesome states of mind—spanning meditation, prayer, collective cultural rituals, and psychedelic therapies. I approach these topics from an interdisciplinary perspective, integrating cognitive science, neurobiology, computational modeling, and phenomenology to investigate mechanisms of self-regulation and transformation. He is currently pursuing my doctoral studies in Neuroscience at McGill University under the supervision of Dr. Michael Lifshitz, with co-supervision from Prof. Dr. Karl Friston. His academic journey includes a master’s degree in Mind, Language, and Embodied Cognition from the University of Edinburgh (UK) and undergraduate studies in Liberal Arts and Sciences at University College Maastricht (Netherlands).

Quotes:
“What we're trying in, in meditation is starting to model our predictive hierarchy of the brain opaque. So to notice that experience ultimately is not something that's, that's kind of a real grasp on reality, that all we have is this imprint of reality on our experiential or generative modeling, through this, this predictive hierarchy.”
"The interplay between micro and macro perspectives mirrors the flexibility we aim for in meditation and science."
"Epistemic vulnerability can be a doorway to growth if properly framed—or a risk without it."
