#112: The Illusion of Self: Nondual Meditation & Brain Science - John Dunne, PhD

The Illusion of Self: Nondual Meditation & Brain Science with John Dunne, PhD explores how our sense of identity is constructed moment by moment, drawing on Buddhist philosophy, neuroscience, and contemplative practice to explain why thoughts feel real and how seeing through them can fundamentally change our experience. In this episode of The FitMind Podcast, we sit down with John Dunne, PhD —a leading scholar-practitioner bridging ancient wisdom and modern science—to examine the nature of mind, self, and awareness. Rather than treating thoughts as accurate reflections of reality, John frames them as useful but often misleading constructions shaped by the brain's attempt to predict and navigate the world. We explore how meditation helps us "de-reify" thoughts—seeing them as mental events rather than truths—and why this shift may be central to reducing anxiety and depression. John also breaks down non-dual traditions like Mahamudra and Dzogchen, offering a clear lens into practices aimed not at changing experience, but at recognizing its underlying nature. Topics include: How the brain constructs a sense of self through predictive models Why thoughts feel real and how to see through them The role of meditation in shifting our relationship to thinking Differences between gradual and non-dual approaches to practice What "effortless awareness" means and why it matters Scientific insights from studying advanced meditators A grounded, intellectually rich conversation for anyone interested in understanding the mind more clearly, working with difficult thoughts, or exploring the intersection of neuroscience and contemplative practice.
