Zazen

Definition

Pronunciation: ZAH-zen

Also spelled: Tso-ch'an, Zuochan, Sitting Zen

Zazen combines za (sitting) and zen (meditation, from the Sanskrit dhyana). It refers specifically to the seated meditation practice of Zen Buddhism, distinguished from other Buddhist meditation forms by its emphasis on objectless awareness and the identity of practice with enlightenment.

Etymology

The Japanese zazen derives from the Chinese zuochan (坐禅), itself a translation of the Sanskrit concept of dhyana (meditative absorption). The character za/zuo (坐) depicts two people sitting on the earth, suggesting grounded stability. Chan/Zen (禅) is the Chinese phonetic rendering of the Sanskrit dhyana, which the Yoga Sutras define as the sustained flow of attention toward a single point. In Chan/Zen usage, the meaning shifted from concentrated absorption on an object to objectless sitting — awareness without a target — reflecting the tradition's distinctive understanding that meditation is not a means to enlightenment but enlightenment expressing itself.

About Zazen

Bodhidharma, the semi-legendary Indian monk who brought Chan to China in the early sixth century CE, reportedly spent nine years facing a wall at Shaolin Temple. Whether historically accurate or not, this image — a human being sitting still, facing a wall, doing nothing recognizable — became the founding icon of the Zen tradition. Zazen is what Bodhidharma was doing, and what every Zen practitioner since has been invited to do.

The physical form of zazen follows precise specifications that have remained largely unchanged since the Song Dynasty (960-1279 CE). The practitioner sits on a cushion (zafu) placed on a mat (zabuton), in full lotus (kekkafuza), half lotus (hankafuza), Burmese position, or seiza (kneeling). The spine is erect but not rigid, the chin slightly tucked, the eyes half-open and directed downward at a 45-degree angle toward the floor or wall. The hands form the cosmic mudra (hokkai-join): left hand resting on right, palms up, thumb tips lightly touching to form an oval. Dogen described this posture in the Fukanzazengi (Universal Recommendation for Zazen, 1227) as the dharma gate of ease and joy.

The instruction for what to do with the mind during zazen varies by school and teacher. In Soto Zen, following Dogen, the fundamental practice is shikantaza — 'just sitting.' There is no object of concentration, no mantra, no visualization. The practitioner sits with alert, receptive awareness, neither grasping at thoughts nor pushing them away. Dogen wrote in the Shobogenzo: 'Think of not-thinking. How do you think of not-thinking? Nonthinking (hishiryo). This in itself is the essential art of zazen.' Hishiryo — a state of awareness that is neither thinking nor suppressing thought — captures Soto Zen's central instruction.

In Rinzai Zen, zazen typically involves concentration on a koan or on the breath (susokukan — counting breaths from one to ten, then beginning again). Hakuin Ekaku emphasized that zazen without koan work was like a horse cart without wheels. The koan provides a focal point that concentrates the mind's energy to a breaking point, producing the 'great doubt' that precedes satori (sudden awakening). In practice, most Rinzai training begins with breath counting to build concentration (joriki), then transitions to koan practice once the student can sustain attention without persistent distraction.

The daily structure of zazen in a monastery (sesshin during intensive retreats, or the regular daily schedule) follows a rhythm established in Chinese Chan monasteries. A typical session lasts 25-50 minutes, punctuated by kinhin (walking meditation) between rounds. During sesshin (intensive retreats lasting 1-7 days), practitioners may sit 10-14 hours per day. The jikijitsu (timekeeper) signals the beginning and end of each period with a bell. The kyosakusu (encouragement stick) — a flat wooden stick administered to the shoulders by a senior practitioner — is used during extended sitting to maintain alertness and release tension, applied by request or when a sitter is visibly struggling.

Dogen's philosophical framework for zazen diverges radically from the instrumental view of meditation common in other Buddhist schools. In the Bendowa (Negotiating the Way, 1231), he argued that zazen is not a practice that leads to enlightenment — zazen is enlightenment. This identity of practice and realization (shusho ittai) is the cornerstone of Soto Zen. When you sit in zazen, according to Dogen, you are not a deluded person trying to become a buddha; you are a buddha expressing buddha-nature through the act of sitting. This is not a metaphor or an aspiration but an ontological claim: the universe practices zazen through you.

The physiological effects of sustained zazen practice have been studied extensively since Herbert Benson's research in the 1970s. Consistent findings include decreased cortisol production, reduced default mode network activity (the brain's self-referential narrative system), increased gray matter density in regions associated with attention and emotional regulation, and a shift toward parasympathetic nervous system dominance. A 2011 study by Brewer et al. at Yale found that experienced meditators showed significantly reduced activity in the medial prefrontal cortex — the brain region most associated with the sense of a separate self — confirming from a neuroscientific angle what Zen masters have reported for centuries.

Zazen in the Rinzai tradition serves as the foundation for sanzen (private interview with the master). The student's zazen generates the concentrated state necessary to penetrate koans; without the sustained stillness and attention that zazen cultivates, koan work becomes mere intellectual exercise. Hakuin described the relationship between zazen and koan work using the metaphor of a hen sitting on an egg: zazen provides the constant warmth without which the egg of awakening cannot hatch.

The common misconception that zazen requires emptying the mind of all thoughts misrepresents the practice. Thoughts arise during zazen as naturally as waves arise in the ocean. The instruction is not to stop thinking but to stop following thoughts — to let them arise and pass without adding a second thought about the first. Shunryu Suzuki, in Zen Mind, Beginner's Mind (1970), compared this to watching a train pass: you see the cars go by but you do not board. This non-grasping awareness is itself the practice and, according to Dogen, itself the realization.

The ethical dimension of zazen is often overlooked in Western presentations that emphasize stress reduction. In the monastic context, zazen is embedded within the Bodhisattva precepts (jukai) and the daily rhythms of work (samu), eating (oryoki), and community life. Dogen insisted that zazen performed without ethical commitment was not zazen at all but merely sitting with crossed legs. The posture of zazen — stable, upright, alert, receptive — is understood as a physical expression of the vow to awaken for the benefit of all beings.

Significance

Zazen stands as the defining practice of the Zen tradition and one of the most influential meditation forms in world history. Its transmission from India through China to Japan — and in the twentieth century to Europe and the Americas — represents a continuous lineage of seated meditation spanning over two millennia.

Dogen's philosophical reframing of zazen as practice-realization (shusho ittai) constitutes one of the most radical claims in Buddhist thought. By collapsing the distinction between the path and its goal, Dogen eliminated the instrumental relationship between meditation and enlightenment that had structured Buddhist practice for centuries. This move had profound implications: if zazen is already enlightenment, then the motivation to sit shifts from self-improvement to expression — from gaining something to manifesting what is already the case.

In the twentieth century, zazen became the primary vehicle through which Zen entered Western culture. Teachers including Shunryu Suzuki, Taizan Maezumi, and Robert Aitken established zazen-centered practice communities across North America that now constitute an established contemplative tradition. The scientific study of zazen has contributed significantly to the emerging neuroscience of meditation, particularly regarding attention, self-referential processing, and the neural correlates of objectless awareness.

Connections

Zazen provides the physical and mental foundation for koan practice in the Rinzai tradition and is itself the central practice in Soto Zen's shikantaza (just sitting) approach. The sudden insight that arises from sustained zazen — whether through koan work or objectless sitting — is called satori or kensho.

Zazen's emphasis on posture and embodied awareness connects it to the broader Buddhist understanding of mindfulness practiced through the body, as taught in the Satipatthana Sutta. In the Tibetan tradition, the parallel practice of shamatha (calm abiding) meditation serves a similar stabilizing function, though the Zen approach to zazen — particularly Dogen's insistence that sitting is not a means but an end — differs from the Tibetan framework where shamatha is typically preparatory to vipashyana (insight). The concept of buddha-nature provides the philosophical ground for Dogen's claim that zazen is enlightenment: because awakening is already present, practice reveals rather than produces it. The Zen Buddhism section explores these relationships in the context of lineage and transmission.

Frequently Asked Questions

How is zazen different from mindfulness meditation?

Mindfulness meditation as popularized in the West (derived from the Theravada vipassana tradition) typically involves observing mental and physical phenomena — thoughts, sensations, emotions — as they arise and pass. The meditator maintains a witnessing stance toward experience. Zazen, particularly in the Soto tradition of shikantaza, does not establish this observer-observed duality. There is no instruction to 'watch your thoughts' or 'note sensations.' Instead, the practitioner drops into a state that Dogen called hishiryo — nonthinking — which is prior to the division between observer and observed. In practical terms, zazen also places far greater emphasis on physical posture as integral to the practice, whereas mindfulness meditation can be practiced in any position.

Do you have to sit in full lotus to do zazen?

Full lotus (kekkafuza) is considered the ideal posture in traditional Zen, and Dogen recommended it in the Fukanzazengi. However, every legitimate Zen teacher accommodates physical limitations. Half lotus, Burmese position (both knees touching the floor with legs uncrossed), and seiza (kneeling on a bench or cushion) are all accepted alternatives. Some practitioners use chairs. The essential requirements are a stable base, an erect spine, and the capacity to remain still for the duration of the sitting period. Forcing the body into a painful position that the practitioner cannot sustain defeats the purpose — zazen is not an endurance test but a settling into natural stability. The cosmic mudra (hands in the lap, thumbs touching) can be maintained in any seated position.

What should you think about during zazen?

In Soto Zen, the answer is: nothing in particular. The instruction is shikantaza — just sitting — which means maintaining alert, open awareness without directing attention toward any specific object. Thoughts will arise; the practice is to let them pass without engaging them, like clouds moving through the sky. In Rinzai Zen, the practitioner typically holds a koan as the content of awareness — not thinking about the koan analytically but letting it saturate consciousness. Beginners in both traditions often start with breath counting (susokukan): counting each exhalation from one to ten, then starting over, returning to one whenever attention wanders. The key point across all approaches is that zazen is not a thinking exercise — it is a practice of returning to immediate, nonconceptual presence.
