Sitting still with the stray thoughts

Do you meditate when you wake in the morning, or before you go to sleep at night?

Speak of meditation today and the methods are beyond counting, from styles rooted in Indian tradition to the practices of Japanese Zen. Yet how many of us grasp that meditation is not merely a way to relax, but a way of treating the root of the illness we carry as human beings?

I meditate only at night, before sleep. After years of trial and error, I settled on the practice that finally made sense in my own body: what is called seiza (静座).

The word requires a moment's care, because in Japanese the sound "seiza" carries two meanings. The seiza (正座) commonly spoken of in Japan means "sitting in the proper posture" as a matter of etiquette, the way one sits in the tea room. The seiza (静座) I mean here has the same sound but a different character and meaning: "sitting in stillness." Both carry the sense of discipline, yet to my mind seiza as sitting in stillness holds the deeper sense of self-cultivation.

Moreover, while the posture of seiza belongs to the lineage of Zen, sitting in stillness has its source not in Zen but in Confucianism. A deeply Confucian philosophy runs through it, and set beside Zen or Buddhist meditation, its way of thinking feels markedly different.

Much of what is spoken of today in the context of mindfulness — with Zen meditation as its emblem — seems to set its goal as clearing away stray thoughts in order to reach a state of nothingness, mu (無). Indeed, most practitioners of Zen seem to believe that this state of nothingness lies on the far side of banishing stray thoughts, and take reaching it to be the very purpose of meditation.

Stray thoughts are certainly a nuisance in daily life. They get in the way of our work, our lives, and our thinking, and at times throw us into doubt and send us in the wrong direction. It is only natural that we come to resent them as we try to live. Historically, from the moment stray thoughts first arose in human beings, their presence was seen as a problem, and one could say that the earliest forms of religion sprang into motion as an answer to it. At root, religion seems to me to have begun from the question of how to interpret and handle the stray thoughts generated by the development of the human brain. Because the methods, practices, and ideals devised in response took on different shapes under the conditions of each place, the seeds of religion sprouted in all their variety across the world — some holding up God as the ideal, some a particular figure, some nature itself. Whatever the early form of faith, looking first at this problem of stray thoughts brings the common root of all religions into view. Seen this way, the question is universal, bound up with the whole of human history: how are we, today, to handle the stray thoughts that rise within us?

To face this question, I want to pursue my own inquiry into what the true fruit of Zen really is.

Meditation is generally taught from the premise: "Do not be caught by stray thoughts." Broadly speaking, there are two ways of dealing with them: one is to remove them, the other to leave them alone. Yet here lies the first problem. To ask of meditation that we catch each stray thought as it arises and clear it away means that thought itself has never stopped. In that condition, no matter how many stray thoughts we sweep away, we will never reach a state of nothingness. More than that, the very wish to reach a state of nothingness is itself a human desire.

In reaction to this came the second way: leaving stray thoughts alone, on the premise that there is no need to turn them into some other thought. To my mind, Zen has placed its weight on this side. D. T. Suzuki, who carried Zen to the world, is a clear example: what defined his approach was that he rejected the older methodology of denying the rise of stray thoughts, and instead taught the practice of Zen by actively affirming them. In the very act of seeking a state of nothingness or stillness, doubt and confusion — our losing of the way — have already begun. And people then lose their way over how to deal with that losing of the way. Once caught in an endless loop of doubt upon doubt upon doubt, it is hard to break free alone, which is why masters are sought out. Yet it is questionable whether those called masters understand this problem themselves.

In the end, doesn't a good human life come down to how we can give ourselves wholly to our own life without losing our way, and live it through to the end? Whatever our circumstances, whatever the course of our life, if we can meet the doubts that arise without losing our footing and give ourselves until the final moment of death to the task that is ours to fulfill — that is the happiest of lives.

Here, the great error — one that Suzuki himself often warned against — lies in taking the state of nothingness to mean simply a state in which nothing is there, a mind emptied of stray thoughts. That reading leads to a dangerous fall. In practice, the spiritual products and services packaged for consumer society as the goal of meditation are rife with this careless understanding, simply because it is easier for users to grasp and easier to turn into money. Yet trying to rid oneself of stray thoughts because they arise in meditation is itself a selfish desire; we need to recognize that even the desire to be rid of desire is still desire.

The fall begins, then, from the premise of setting a purpose for meditation at all. Because stray thoughts arise, people make it their purpose to remove them, or to leave them alone, or to observe them from a distance. All manner of purposes can be set up, yet each does no more than lift out one effect of meditation and turn it into a general rule. In doing so, it hides the deeper quality meditation possessed: the power to treat the root of our human malady. This is true not only of Zen meditation, but of Confucian seiza as well. Historically, it too has drifted from its center, and there is likely almost no one left who understands and practices what lies at its core. If we ask what the essence of Confucian seiza is, it lies in seeing that to recognize a stray thought as a stray thought is already awakening — or in the language of Zen, satori (悟り).

Seen in this light, what matters is not to agonize over the rise of stray thoughts, nor to chide ourselves as immature because we are swayed by them. Still less should we throw ourselves into confusion by treating stray thoughts as an object to be managed, left alone, or solved. Simply to know a stray thought as a stray thought is what matters in living a human life. Once we see this, we can picture how people wander lost in a world without answers, losing their footing inside that endless loop. Precepts such as "Do not be caught by stray thoughts," "There is no need to turn them into another thought," or "Devise various techniques for meditation and seiza" are not the essence at all; they are merely part of the elaborate ornament that has gathered around meditation over the centuries. Because it is ornament, it catches the eye across the ages and draws people in — yet the fruit of meditation is not there. Rather, that ornament is the very root from which people's confusion springs.

At this point, the question of stillness, sei (静), and movement, do (動), rises to the surface from the perspective of Eastern thought. One answer is to enter straight into stillness itself, and straight into movement itself. Put another way, to enter wholly into movement is stillness, and to enter wholly into stillness is movement. We can call this the non-separation of stillness and movement, seido furi (静動不離), or the unity of stillness and movement, seido goitsu (静動合一), and in grasping it, the true worth of Zen comes into view. Yet this is not something that can be understood as knowledge; it is a state that cannot be reached unless each person embodies it in daily life.

As I have reflected on the history of Zen in Japan, something has gradually come into focus: the defining trait of Zen, and what I find most admirable in it, is its stance that everything begins from first understanding one's own limits. It is a remarkable cast of mind.

In most religions, setting limits at the outset gets in the way of winning followers and spreading the faith, so limits are veiled and turned into ideals, or the goal is placed in some transcendent realm. I see Zen as having been born originally out of everyday human life as a reaction against that religious impulse. What is compelling about Zen is that it draws a line in advance — acknowledging that the veiled ideals of religion and arrival at some transcendent state are out of reach — and locates that limit as something already present within oneself. By doing so, it dismantles the single, uniform dogma of religion and makes it possible to offer an answer fitted to each individual, because each person's limit is different. And the grace of Zen lies in its clean premise that beyond that limit, so long as we are human, no one can possibly know.

When we ask where Zen set its own limit, and what it taught once that limit was set, we can truly touch the heart of Zen. What matters here is not that a monk who studied Zen taught this, but that Zen itself taught it. I understand this quality of Zen through the Buddhist concept of teinen (諦念) — clear-eyed acceptance or resignation — and the crucial point of Zen's teaching is that this teinen is what matters most for us.

Once human beings reach a certain realization or goal, we cannot help growing ever more greedy for the next. Under modern capitalism, this tendency has grown acute and beyond self-correction, because people believe that the law of endless upward growth will continue forever. Yet the notion that upward growth continues forever is a joke, nothing more than an irony. If we ask what we can learn from Zen today, it is not formalized methods or styles of meditation, but the essence of Zen: to set teinen at the very beginning. Simply put, to think of the end first.

We begin by knowing our own limits, and reckon backward from those limits to how we will live our life. Unless each of us — whether we follow Zen or not — comes to know this remarkable method in our bones, the illusion of endless upward growth will never end. When we understand within our own limits that upward growth is not eternal, we become able, at the very moment we set out to begin something, to think of its end. Living with the end in mind was once a vital Japanese virtue. The Japanese of the past were able to live their lives cleanly and to the full precisely because they kept the end in view. Samurai and Zen understood each other so deeply because both knew that everything begins from thinking of the end. This is the fruit of Zen.

By contrast, no life loses its tautness and vitality more surely than one that never thinks of the end. In the modern world especially, starting something is easy; thinking of how it ends is fiercely difficult. When you have begun a project in your own life, have you ever started by thinking first of how it will end? For most people, the answer is almost certainly no. Thinking at the outset of how to bring something to an end is at once the hardest and the most indispensable question in the modern world, yet almost no one looks there. People do not even know that such a way of thinking exists. So they start one thing after another, clinging to the effort to keep that upward curve rising. In the end they exhaust themselves, lose interest in their own work, lose their fire, and slowly fade out — because there is no such thing as endless upward growth.

What Zen teaches is a warning against this drift: understand your own limits first, and by reckoning backward from those limits, create your possibilities. One's limits naturally differ from person to person. Religion flattens this into a single mold and generalizes human beings, declaring that there is one limit, one destination, or one transcendent goal in order to gather believers. What is fascinating about Zen is that it begins by taking for granted that this differs for each person. I see in this the historical root where Zen, in China, inherited the original character of Confucianism: traditional Chinese Confucianism met the newly arrived Zen, and the philosophical marriage that took place there was eventually carried to Japan and digested in its own way. That history may sound tangled, yet what it comes down to is simply the right answer for each person.

This opens the way for each of us to ask for ourselves: where do my own limits lie, and where must I first find teinen? At that moment, almost everyone realizes how little they actually know themselves. That realization — the discovery that one does not yet know oneself — can in Confucian terms be called true awakening. And this foothold is where the inward inquiry I value most begins, and where the real depth of living lies. Everything begins from realizing, I do not know myself, and from there coming to understand oneself thoroughly through introspection. To understand oneself here does not mean looking first for one's possibilities; it means knowing one's limits. When we think of possibilities first, our thinking scatters and thins out; when we understand our limits first, our possibilities come naturally into focus within those bounds.

The modern world is saturated in every corner with the delusion that anyone can become anything and that our possibilities are boundless — and that delusion is quietly ruining people's lives. It is not true. Each person has their own native grain and disposition, and because we have a particular grain, we have limits. Just as life begins to shine when we hold death in mind, our possibilities begin to shine when we know our limits. Once we take this reversal of thought as our premise, all manner of modern ills become plain to see. On an individual level, the greatest affliction of our time is comparing oneself with "someone else," yet once we understand the possibilities of our own grain from within our own limits, anyone can see how foolish such comparison is. Having taken the measure of those limits, we practice teinen — the clear-eyed acceptance that lets go — and in the Zen way of practice, life finally begins to shine.

This, I believe, is the true core of meditation, and those who teach meditation ought to guide each practitioner by a different path so that they can arrive here for themselves. Meditation gatherings of all kinds are held in Japan and around the world, yet crowding a great number of people into one room to sit beneath a single master can never make this possible. What will be needed in the years ahead is a way of meditation that meets each person one by one — and its foundation will be what I have set down here.

Tonight, or tomorrow morning, whatever your method or style of meditation, try sitting once with this thought as your premise. A good place to begin may simply be to notice how you yourself feel toward the stray thoughts that arise.

Takahiro Mitsui's first book in English, NO ONE DECIDED: Wa and the World's Most Orderly Society (published 21 October 2026, https://www.amazon.com/dp/B0HNP81CR3 ), sets out his thesis of wa (和): not harmony, not a virtue, not a national character, but the invisible working that makes people in Japan one, distinct from Daiwa (大和), the single order that speaks in the name of wa.

In Takahiro Mitsui's own words: “Wa is not harmony. No one decided, and yet it is decided.” (Project 2049 Vol.3, https://project-2049.takahiromitsui.com/vol-3 )

In Takahiro Mitsui's own words: “What changes the nature of wa is not the praxis of a subject but the actual practice of everyday life.” (NO ONE DECIDED: Wa and the World's Most Orderly Society (2026), ch. 16, https://www.amazon.com/dp/B0HNP81CR3 )
