The mindfulness industry has, by most measures, succeeded. Headspace and Calm have tens of millions of subscribers. Corporate wellness programs include MBSR (Mindfulness-Based Stress Reduction) training. The neuroscience supporting the benefits of basic attention training—for stress reduction, emotional regulation, attention capacity—is now sufficiently robust that its clinical applications are uncontroversial. What has happened in this mainstreaming is a compression of a vast contemplative tradition into its most accessible and marketable form. The frontier of serious meditation practice lies considerably further along the developmental path, in territory that most practitioners and nearly all wellness consumers have not approached.
Jhāna (Pali: jhāna; Sanskrit: dhyāna, from which “Zen” and “Chan” derive) refers to states of absorbed concentration described in the earliest Buddhist texts as milestones on the contemplative path. They are not the same as ordinary focused attention, not the same as deep relaxation, and not the same as the insight states that constitute the other major branch of Buddhist practice. They are specific, reproducible, hierarchically organized states of consciousness whose characteristics are described with unusual precision in the Pali Canon and whose contemporary relevance is the subject of increasing attention from both contemplative scholars and neuroscientists.
The Jhana Map: Eight States
The classical jhana literature describes eight distinct absorption states, divided into four form jhanas (rupajhana) and four formless jhanas (arupajhana). The form jhanas are more commonly discussed in contemporary contemplative communities because they are more accessible within retreat conditions and more directly correlated with the neurological signatures that have attracted research interest.
The first jhana is characterized by the presence of applied thought (vitakka), sustained thought (vicara), joy (piti), pleasure (sukha), and one-pointedness of mind (ekaggata). It requires a substantial deepening of concentration beyond ordinary mindfulness—typically described as requiring sustained practice of several years or concentrated retreat time of weeks or months. The access concentration required to enter first jhana is described as nimitta, an internal visual or somatic sign that signals readiness for absorption.
The second jhana drops applied and sustained thought while intensifying joy, pleasure, and concentration. The third jhana dissolves joy while pleasure and equanimity intensify. The fourth jhana is characterized by profound equanimity and one-pointedness, with the fading of pleasure into a vast, spacious stillness.
The formless jhanas extend beyond form altogether: boundless space, boundless consciousness, nothingness, and the state known in English as neither-perception-nor-non-perception. These states are described by advanced practitioners as profoundly non-conceptual and are among the most difficult to communicate or verify from outside the tradition.
Pa-Auk Sayadaw: The Classical Systematizer
Pa-Auk Tawya Sayadaw, the Burmese monk whose texts and international retreat program have become the most systematic contemporary presentation of jhana training, has done more than any living teacher to make the precise classical method accessible to serious Western practitioners. His method begins with kasina (visual concentration objects—a disk of light, a colored circle—held as stable mental images) or breath-based nimitta development, and proceeds through the form and formless jhanas in strict classical sequence before introducing insight practice.
The Pa-Auk method demands extended retreat commitment. Serious practitioners typically spend three to six months in continuous retreat at Pa-Auk monasteries in Myanmar or at affiliated centers in Malaysia, Taiwan, and increasingly the United States. The daily schedule involves approximately twelve hours of formal meditation, alternating between sitting and walking. The precision of the Pa-Auk method is its greatest strength and its greatest barrier: the systematic verification of each jhana by the teacher before proceeding to the next ensures that practitioners are not confusing deep relaxation or hypnagogic imagery with genuine absorption, but the requirement for extended residential commitment places it beyond reach for most practitioners.
Pa-Auk Sayadaw’s principal texts—“Knowing and Seeing” and “The Practice That Leads to Nibbana”—are available in English and provide the most detailed technical description of classical jhana training in the contemporary literature.
Leigh Brasington and the Accessible Approach
Leigh Brasington, a software engineer who practiced extensively in the Pa-Auk tradition before developing his own approach under the guidance of Bhante Gunaratana and other teachers, has articulated what he calls “the jhanas according to Bhante G”—an approach that emphasizes access to jhana-adjacent states for practitioners who cannot or will not commit to months of intensive retreat.
Brasington’s method is more lenient about what constitutes genuine jhana, accepting lighter states of absorption that not all classical teachers would recognize as meeting the canonical criteria. His workshops at Spirit Rock Meditation Center in Woodacre, California, and his book “Right Concentration” have introduced jhana practice to thousands of practitioners who might otherwise never encounter it. The debate within contemplative communities about whether Brasington’s “jhana-adjacent” states represent genuine form jhanas or deep access concentration is substantive and probably unresolvable without better measurement tools—but the practical benefit of his approach is that it makes the distinctive phenomenology of jhana available as a reference point for practitioners whose lives do not accommodate months in a Burmese monastery.
Spirit Rock and Retreat Infrastructure
Spirit Rock Meditation Center occupies 411 acres in the rolling hills of Marin County, California, and operates within the Theravada-derived Insight Meditation tradition founded by American teachers including Jack Kornfield, Sharon Salzberg, and Joseph Goldstein. Its intensive retreat program includes a small number of jhana retreats annually, typically led by Brasington or other teachers with explicit jhana training, and has become the primary venue for serious jhana instruction accessible to North American practitioners without Southeast Asian travel.
The Spirit Rock jhana curriculum typically spans seven to ten days of silent retreat, integrating concentration practice with the theoretical framework necessary to recognize and work skillfully with absorption states. The limited availability of these retreats—the jhana-specific programs fill months in advance—reflects both the depth of interest in advanced practice and the genuine scarcity of teachers qualified to guide it safely.
Beyond Spirit Rock, the Insight Meditation Society (IMS) in Barre, Massachusetts, offers three-month intensive retreats that, while not exclusively jhana-focused, provide the conditions under which serious concentration development becomes possible. The IMS three-month retreat has been the formative training ground for a generation of Western insight teachers and has produced the practitioners whose research cooperation has made contemplative neuroscience possible.
Neuroscience Correlates: What Brain Imaging Has Found
The neuroscience of jhana states is in its early stages but has produced findings that cannot easily be dismissed. Zoran Josipovic, a researcher affiliated with New York University, has conducted the most sustained program of neuroimaging of non-dual and absorption states, finding that these states involve marked suppression of default mode network (DMN) activity—far greater than that observed in ordinary mindfulness meditation—combined with increased activity in attention and interoceptive networks.
The distinctive EEG signature most consistently associated with jhana-like states is high-amplitude gamma oscillation (30–100 Hz). The Matthieu Ricard data, collected by Richard Davidson’s laboratory at the University of Wisconsin-Madison, found extraordinarily high gamma power in an experienced Tibetan Buddhist practitioner during specific meditation types, with coherence across widespread brain regions that had not previously been documented in any other cognitive condition. While Ricard’s particular tradition maps onto jhana states differently than Theravada practice, the gamma coherence finding is consistent across advanced practitioners in multiple traditions.
What practitioners report from within jhana states—the dissolution of ordinary self-referential thinking, the quality of profound stillness in the fourth jhana, the expansion of consciousness in the formless attainments—corresponds structurally to what neuroscience is beginning to measure: profound DMN suppression, large-scale gamma coherence, and interoceptive processing patterns that differ categorically from both ordinary awareness and ordinary sleep. The states are not mystical in the sense of being outside scientific examination. They are, rather, at the edge of what contemporary measurement tools can reach—which is itself a meaningful finding about the depth and breadth of what sustained contemplative practice can achieve.
