“The zazen I speak of is not meditation practice. It is simply the dharma gate of repose and bliss, the practice-realization of totally culminated awakening. It is the manifestation of ultimate reality.”
— Dōgen, Fukanzazengi
What it is
Za means sitting; zen is Japanese for chán, which is Chinese for dhyāna, the Sanskrit word for meditative absorption. Zazen — seated meditation — is the central practice of Zen Buddhism, continuous with the meditation the Buddha is said to have practiced under the Bodhi tree, but received, shaped, and named by the Chinese Chan masters and brought to Japan in the twelfth and thirteenth centuries.
Zen’s characteristic claim about zazen is counter-intuitive: it is not a technique for producing a state. It is not a method for calming down, feeling good, or achieving anything. It is, in the tradition’s own self-understanding, the activity that a buddha does — and since buddha-nature is already present, zazen is not preparation for awakening but the expression of it.
This is what Dōgen means by his unrelenting insistence that practice and realization are not-two. You do not sit to become something. You sit as what you already are, and that sitting is itself the realization.
The posture
The body’s posture is the practice. Get the body right and the mind follows; get it wrong and no amount of mental intention will compensate.
- Cushion (zafu) on a mat (zabuton). Height adjusted so the knees can reach the floor. If the knees cannot reach, use a chair — the posture still works.
- Leg position. Full lotus (kekkafuza) if available; otherwise half lotus, Burmese (both ankles on the floor), kneeling (seiza) with or without a bench, or a chair. Full lotus is best because of its physical stability, not because it is spiritually superior.
- Spine. Upright, lengthened from the crown. Pelvis tilted slightly forward so the lumbar curve is maintained without effort. Shoulders back and down; chest open.
- Hands. In the cosmic mudra (hokkai jō-in): right hand palm up in the lap, left hand in the right, thumbtips lightly touching to form a horizontal oval. The thumbs are a delicate instrument — if they press together you are tense; if they fall apart you are drifting.
- Eyes. Open or half-open, lowered to a point on the floor about three feet in front. Not closed — closed eyes invite dreaming; closed eyes are not zazen.
- Mouth. Closed, teeth lightly touching, tongue on the upper palate.
- Breath. Through the nose. Long, slow, belly-centered. In Rinzai and Sanbō-Zen traditions, counting breaths (susokukan) is the beginner’s method; in Sōtō, breath is observed rather than counted.
The posture itself is the teaching about the body’s capacity to carry attention without effort. A properly sat zazen posture can be held for forty minutes without any of the adjustments a slumped posture demands every three minutes.
How to work with the mind
Two main approaches:
Shikantaza — just sitting (Sōtō)
“Just sitting” is Dōgen’s and the Sōtō lineage’s method. No object. No mantra. No counting (beyond perhaps an initial settling period). The practitioner sits, breath as background, eyes open, and watches — or rather is — whatever arises.
Thoughts come. In shikantaza you neither follow them nor push them away. You let them arise and let them pass, as clouds cross a sky. You do not try to make the mind blank; you try to stop preferring the mind to be any particular way.
The instruction is deceptively simple and takes decades to inhabit. Beginners often think shikantaza means “doing nothing” and proceed to daydream; it does not. Shikantaza is alert, embodied, and hard. It is the practice of staying with what is, without interference, for as long as the sitting lasts.
Koan introspection (Rinzai)
In Rinzai Zen, the practitioner receives a kōan from their teacher in private interview (dokusan) and sits with it. The kōan is not a puzzle to solve with the discursive mind; it is a question the discursive mind cannot resolve, and the sitting is the attempt to stay with the question until some other mode of understanding becomes available.
The classical beginner’s kōan is Mu: a monk asked Chao-chou, “Does a dog have buddha-nature?” Chao-chou answered, “Mu.” The student sits with mu, returns to mu, breathes mu, dreams mu, is interrogated by the teacher on mu, until mu has emptied the categories that made the question a question.
The two approaches are traditionally distinguished but can be combined. Many modern teachers give beginners shikantaza and introduce kōan work later, or run both as parallel practices.
The breath, the interval, the whole
Across both approaches the breath is the practice’s spine. You do not manipulate it; you accompany it. The out-breath is especially important — most teachers will instruct you to let the out-breath extend, slowly, until the bottom of the breath is a true stillness before the in-breath arrives. The gap between breaths is the tradition’s teaching instrument.
Duration and frequency
Traditionally, zazen is sat in periods of 30–50 minutes, with a walking meditation (kinhin) interval between periods. Daily practice for a layperson: 20–40 minutes once or twice a day, sustained. Intensive practice: a sesshin (“touching the heart-mind”) retreat of three to seven days, with ten or more periods of zazen daily, interspersed with walking, meals, and teacher interviews.
The tradition’s emphasis is on continuity rather than duration. Ten years of daily twenty-minute zazen will take you further than an annual week-long retreat without daily practice.
Cautions
- The body needs preparation. Long-term zazen without attention to stretching, physical exercise, and good posture can produce knee, hip, and back injury. Respect the body.
- Intense meditation can release psychological material that is not always well-handled alone. If you do not have a teacher and you begin to encounter material that is destabilizing, find one, or pause formal practice. This is not a failure of the method; it is a feature of the method.
- Zazen is not self-improvement. If you find yourself tracking your “progress,” noting your “good sits” against your “bad sits,” you are not doing zazen — you are doing a project about zazen. The actual practice has no progress to track.
- Teachers matter. Zazen learned from a book is partial. A teacher corrects the posture, refines the attention, and meets the practitioner where they actually are. Where lineages have failed this function, it has usually been a failure of teacher integrity — not of the form itself.
Across traditions
Zazen is specifically Zen, but its closest relatives are:
- Śamatha — the Indo-Tibetan “calm abiding” tradition. Similar posture, similar breath, but typically with an object (the breath, a syllable, a visualization). Zazen dispenses with the object.
- Vipassanā — insight meditation in the Theravāda tradition. Overlaps in posture; differs in method (note-labeling, systematic investigation of mental contents).
- Centering prayer — the Christian contemplative practice revived in the twentieth century. Uses a sacred word rather than bare attention; structurally adjacent.
- Silent meditation as practiced in various modern secular traditions. Often draws unknowingly from zazen via Kabat-Zinn’s MBSR lineage. Useful; incomplete without the Buddhist philosophical frame zazen is held inside.
What it is for
The tradition refuses this question. Dōgen’s response, roughly: asking what zazen is for is like asking what walking is for. Walking is not for arriving somewhere; walking is itself the activity of the walker. Zazen is not for enlightenment; zazen is itself the activity of a buddha. If you cannot yet see this, sit anyway. The sitting will show you what the asking could not.
“To study the Buddha way is to study the self. To study the self is to forget the self. To forget the self is to be actualized by the myriad things. To be actualized by the myriad things is to let fall the body and mind of the self and the selves of others.”
— Dōgen, Genjōkōan
