Zen Practice (Zazen and Beyond)

Zazen, shikantaza, koans, and beginner’s mind — mechanisms and honest evidence

What are the core practices of Zen, and what do they do?

Zen centers on zazen — seated meditation — in two main forms: shikantaza ("just sitting" in open awareness) and koan practice (sustained inquiry into a paradoxical question). Alongside these sits "beginner’s mind," the attitude of meeting experience without preconception. These are traditional contemplative practices; some mechanisms overlap with studied attention training, but Zen’s specific aims and claims are largely experiential rather than clinically validated.

Zen is famously sparse: less doctrine, more sitting. Its practices strip meditation down to posture, breath, and a particular quality of awareness — and then, in koan work, deliberately break the thinking mind against an unanswerable question. Below are the core practices, each with the mechanism that makes it more than sitting still, and an honest read on where evidence exists and where the tradition is speaking experientially.

Practices

How these practices connect

Every practice on this page is a way of removing an overlay the mind adds on top of direct experience so awareness can meet things as they actually are, whether that overlay is a wandering focus, the assumption of already knowing, the demand for a verbal answer, or the mental split between 'meditation' and 'ordinary activity.' Zazen posture supplies the stable physical base that makes sustained, undistracted awareness possible in the first place. From there, shikantaza, koan practice, and beginner's mind each strip away a different mental habit that gets in the way of that direct contact, while counting the breath and work as practice extend the same trained awareness outward: one scaffolds it for a beginner, the other generalizes it into daily life.

What's the difference between counting the breath and shikantaza?

Counting the breath (susokukan) gives you a concrete object, the number one through ten, so that a wandering mind becomes immediately obvious the moment you lose count. Shikantaza removes that object entirely and asks you to rest in open, objectless awareness of whatever arises. They are usually taught in sequence rather than as competitors: the counting practice trains the basic capacity to notice when attention has drifted and return it, and shikantaza is the less-scaffolded practice that capacity is meant to support once it's established.

Do you have to sit in zazen posture to do shikantaza or koan practice?

Zazen posture is described as the physical form these practices are done in rather than a separate warm-up step, so shikantaza and koan practice are both typically practiced while seated in it. The mechanism given for the posture is that an upright, stable seat reduces physical fidgeting and supports the calm-but-awake alertness that open awareness or sustained engagement with a koan both depend on. Without that stable base, a mind trying to hold shikantaza's open awareness or wrestle with a koan has to also manage physical discomfort and restlessness at the same time.

Is koan practice just a harder version of shikantaza?

No, they work through different mechanisms rather than sitting on a single difficulty scale. Shikantaza trains open, non-grasping awareness of whatever passes through experience, with nothing specific to focus on or solve. Koan practice does the opposite in form: it gives you a single, deliberately unsolvable question and uses sustained engagement with it to exhaust ordinary problem-solving thought until a non-conceptual shift becomes possible. One opens attention, the other narrows it to the point of breaking the analytic approach entirely.

How is beginner's mind different from just sitting (shikantaza)?

Shikantaza is a seated meditation practice, a specific thing you do on the cushion with a defined form. Beginner's mind is an attitude, a way of meeting any moment, seated or not, without the overlay of assumed expertise or 'I already know this.' They reinforce the same underlying skill, since both work by reducing automatic mental processing of experience, but beginner's mind is meant to be carried into ordinary perception generally, while shikantaza names the formal sitting practice itself.

What's the connection between work as practice and sitting meditation?

Work as practice, or samu, takes the present-moment attention trained during seated zazen and applies it to ordinary tasks like sweeping or cooking, on the reasoning that awareness trained on the cushion is meant to generalize rather than stay confined to formal sitting time. The stated purpose is to dissolve the split between 'meditation time' and 'real life' so the same quality of attention carries into both. In that sense samu is less a separate technique and more a test of whether the attention built through zazen, shikantaza, or breath counting actually transfers outside the seated posture.

If I keep losing count during breath counting, does that mean I'm bad at meditation?

No, losing count is described as the practice working as intended, not a sign of failure. The mechanism behind counting the breath is that it makes a wandering mind immediately visible, since you notice the moment you lose the count and can return to one, and that noticing is itself the skill being trained. The common mistake named for this practice is getting frustrated and quitting each time you lose count, rather than treating it as normal, expected feedback on attention that is still developing.

How do you choose between these?

If you've never sat in meditation before, or you find your mind wandering constantly with nothing to anchor it, counting the breath gives you a concrete object to return to and a clear signal when attention has drifted. If you already have some capacity to notice a wandering mind and want to train open, non-reactive awareness with less structure, shikantaza is the direct next step. If a specific question or contradiction genuinely won't let go of you and ordinary reasoning keeps failing to resolve it, koan practice is designed for exactly that kind of impasse, though the tradition holds it should be done under a teacher's guidance rather than alone. Beginner's mind is not a separate session at all but a stance worth applying whenever you notice yourself running on autopilot because a situation feels familiar. And when you want practice to extend past the cushion into the rest of your day, work as practice is the way that transfer is deliberately trained, by giving full attention to whatever ordinary task is already in front of you.

What these approaches do not settle

None of these six practices have been tested against each other in controlled trials, so claims about which one is 'better' for a given situation are drawn from the traditional mechanisms and reasoning described here, not from comparative outcome research. Koan practice in particular rests on anecdotal tradition rather than any rigorous outcome evidence, and it is traditionally meant to be guided by a teacher, which is a meaningfully different claim than a self-directed technique. The postures and forms themselves, such as the specific hip-above-knee alignment in zazen or counting specifically to ten, are inherited tradition rather than variables that have been isolated and tested, even where the general principles behind them, like stable posture supporting alertness or focused attention improving concentration, have broader research support.

Frequently asked questions

What are the core practices of Zen, and what do they do?

Zen centers on zazen — seated meditation — in two main forms: shikantaza ("just sitting" in open awareness) and koan practice (sustained inquiry into a paradoxical question). Alongside these sits "beginner’s mind," the attitude of meeting experience without preconception. These are traditional contemplative practices; some mechanisms overlap with studied attention training, but Zen’s specific aims and claims are largely experiential rather than clinically validated.

What is Zazen posture: how to sit for Zen meditation?

Zen treats posture as primary, not incidental — in Dogen’s framing the sitting is not a means to awakening but its expression, which is why the form is taught with such care. Practically, a stable, upright, balanced position supports sustained alertness while reducing the physical fidgeting that fragments attention. The specific elements each do work: hips raised above the knees tilts the pelvis forward so the lumbar curve holds the spine erect without muscular effort, which is what lets someone sit still for forty minutes without either slumping or bracing; the half-open, lowered gaze keeps visual input steady and minimal, holding off both the drowsiness of closed eyes and the distraction of an open visual field; and leaving the breath uncontrolled avoids turning respiration into one more task to monitor. Together these nudge the nervous system toward the calm-but-awake state — settled arousal without sedation — that is the physiological substrate everything else in the practice depends on. The posture is not preparation for zazen; it is the shape zazen takes.

How do you shikantaza (just sitting)?

Shikantaza is open-monitoring meditation in its purest form: rather than fixing attention on an object, you rest in bare awareness of whatever arises and passes. This trains a non-reactive, panoramic attention that does not grasp or push away, which can loosen habitual reactivity and the automatic commentary the mind layers onto experience.

How do you koan practice?

A koan ("what is the sound of one hand?") is deliberately insoluble by logic. Sustained, sincere engagement is meant to exhaust discursive, problem-solving thought and create the conditions for a sudden non-conceptual insight. Mechanistically, it pushes against the limits of analytic cognition, loosening the assumption that every question has a verbal answer.

How do you beginner’s mind (shoshin)?

Beginner’s mind deliberately suspends the mental shortcuts of expertise that cause us to perceive our assumptions rather than what is actually present. By approaching even familiar experience as if for the first time, you reduce automatic categorization and open up direct perception, which keeps attention fresh and curious rather than running on autopilot.

What is Counting the breath (susokukan)?

Breath counting gives beginners a concrete, low-stakes object that makes wandering immediately visible (you lose count) and provides a clear point of return. This trains sustained attention and meta-awareness before progressing to the more open, less-scaffolded shikantaza.

How do you work as practice (samu)?

Zen extends practice off the cushion through samu — mindful work. Giving complete attention to a simple task (sweeping, cooking, cleaning) generalizes the present-moment awareness trained in zazen into daily activity, dissolving the split between "meditation time" and "real life" so awareness becomes continuous rather than compartmentalized.

What's the difference between counting the breath and shikantaza?

Counting the breath (susokukan) gives you a concrete object, the number one through ten, so that a wandering mind becomes immediately obvious the moment you lose count. Shikantaza removes that object entirely and asks you to rest in open, objectless awareness of whatever arises.
