Before he was a meditation teacher, Culadasa (born John Yates) spent years teaching physiology and neuroscience at the Universities of Calgary and British Columbia. He also spent over four decades training in both the Theravadin and Tibetan Buddhist traditions before retiring from academia in 1996 to teach meditation full-time. The Mind Illuminated, published in 2015 with co-authors Matthew Immergut and Jeremy Graves, is what happens when that dual background gets put on paper: a meditation manual precise enough to read like a lab protocol.

Instead of “sit and breathe,” the book maps the entire arc of concentration practice into ten clearly defined stages — from establishing a basic daily habit, through overcoming mind-wandering and dullness, to the unification of attention that opens into the deep absorption states known as jhāna. Each stage comes with specific milestones, common obstacles, and troubleshooting advice, plus a running “moments of consciousness” model that explains, in cognitive-science terms, what’s actually happening when attention succeeds or fails.

Culadasa’s core claim is that meditation progress isn’t vague or unmeasurable — it follows a predictable structure that can be diagnosed and trained like any other skill. Most people plateau in practice not because they lack discipline, but because they don’t know which specific problem (forgetting the object, gross distraction, subtle dullness, subtle distraction) is holding them at their current stage, or which specific technique addresses it. The book’s ten-stage model exists to remove that guesswork.

The later stages — where scattered attention becomes fully unified — aren’t just described experientially; they have a measurable signature. A 2004 study led by neuroscientist Antoine Lutz working with Richard Davidson’s lab at the University of Wisconsin–Madison found that long-term meditators could self-induce high-amplitude gamma-wave synchrony during focused practice, a pattern of widespread, coordinated brain activity rarely seen in novice meditators. That’s a plausible physiological correlate of what Culadasa describes as the “unification of mind” in Stages Seven through Ten — scattered sub-processes of attention beginning to fire in coordinated harmony rather than competing with each other.

Culadasa built his ten stages directly on top of an older map: the nine-stage model of mental abiding first systematized by Asanga, the 4th-century Indian Buddhist scholar-monk, in the Yogācārabhūmi-śāstra. Culadasa didn’t invent the structure — he clarified and extended a framework that Buddhist teachers have used for roughly seventeen centuries to track concentration practice stage by stage.

That framework itself traces back to the Buddha’s own instructions on breath meditation in the Ānāpānasati Sutta (Majjhima Nikaya 118), where the Buddha lays out sixteen progressive steps — starting with simply knowing a long or short breath, and moving through calming the body, steadying the mind, and releasing attachment — that lead toward the jhānas, the absorbed states Culadasa’s later stages describe in modern cognitive language. The ten-stage model is best understood as a detailed, annotated map of ground the Buddha first outlined in that sutta.
