What This Concept Is Actually Saying
The phrase comes from Chan Master Dongshan Liangjie's (洞山良价) instruction to his students: *"秋初夏末，兄弟或東或西，須向萬里無寸草處去"* — "At the end of summer, the beginning of autumn, brothers east and west — you must go to the place of ten thousand miles without an inch of grass."
The moment Dongshan finishes saying "go" (*去*), he turns the instruction into a koan: *"既是萬里無寸草，作麼生去?"* — "If there is truly not an inch of grass for ten thousand miles, how do you go?" The very saying of "go" has already planted a seed of direction, a "to" and a "from." So the instruction, taken literally, cancels itself out. That self-canceling is the door.
This is not a place. Two later masters made this unmistakable:
- Shishuang Chuyuan (石霜楚圓) said: "出門便是草" — "Step out the door, and it's already grass." - Dayang Jingxuan (大陽警玄) said: "直道不出門亦是草漫漫地" — "Even if you never step out, the grass grows thick everywhere."
In other words, the "going" (*去*) is not a journey through space. Nor is "staying put" the answer. The "grass" (*cǎo*, 草) is the metaphor for any discrimination that has already taken shape — any trace stamped, any judgment fixed, any direction carved. The "ten thousand miles without an inch of grass" is the moment (or rather, the *non-moment*) when no such stamping has yet crystallized.
What kind of moment is that? Hongzhi Zhengjue (宏智正覺), the Caodong master whose recorded sayings (《宏智禪師廣錄》, T2001) preserve and elaborate this teaching, gives a series of interlocking phrases. They all circle the same axis:
- *"機雖轉紐，印未成文處"* — the mechanism is turning, but the seal has not yet pressed into recognizable form. - *"廓然一念忘緣，泊爾十方無寄"* — a single thought suddenly drops all conditions; nowhere in the ten directions is there any place to rest. - *"箇時淨無夤緣，廓無處所，三際斷六門空"* — at that moment, cleanly without entangling conditions, boundless, no location; the three times are cut off, the six sense-gates are empty. - *"善惡如浮雲，起滅俱無處"* — good and evil are like floating clouds, with no place where they rise or perish. - *"生佛立不得"* — neither sentient being nor Buddha can be set up. - *"不思善不思惡"* — not thinking good, not thinking evil (the famous moment from the Sixth Patriarch Huineng's encounter with the layman Zhizhang, in the 《六祖壇經》). - *"頭角盡，蹤跡絕，岐路斷，心意忘"* — every horn and corner gone, every trace cut off, every branching road ended, every intention forgotten.
The last phrase in this set is the clincher: *"惺惺照得破，寂寂體得到"* — **lucidly (*xīngxīng*, 惺惺) able to shine through it, and still (*jìjì*, 寂寂) able to embody it.** The "no grass" is not blankness. It is not unconsciousness. It is not the absence of awareness. It is precisely the opposite: a traceless lucidity, a wakefulness without a waker, a clarity that does not yet know itself as clarity — because the reflexive move of "I am clear" is itself a stamping, a fresh blade of grass.
This dual structure — *jìjì* (寂寂, profound stillness, traceless) plus *xīngxīng* (惺惺, lucid wakefulness) — is the heart of the teaching. Take away *xīngxīng* and you have torpor, a kind of dull blank; take away *jìjì* and you have ordinary thinking, the mind busy stamping. Together they describe what Hongzhi elsewhere calls *"全超無影迹，不墮古今機"* — completely transcending, without shadow or trace, not falling into any device of past or present.
It is worth noticing that Hongzhi also frames it in the language of the Dharmakāya: *"色轉不見身，功亡不知位"* — when the form (*sè/rūpa*, 色) shifts, no body is seen; when the function (*gōng*, 功) is lost, no position is known. Even the categories of "attainment" and "position" have no standing here. This is not a high spiritual achievement; it is, paradoxically, the most ordinary moment of all — but the moment before any of us has learned to call it ordinary.
So the *one-line* definition: the traceless, lucid "before" of every act of discrimination — the bare pivot of awareness at which no trace has yet been inscribed, and yet awareness is fully and silently awake.
Walking Through It in Daily Life
To "walk through" this concept, we have to map it exactly onto the classical definition, not onto the loose contemporary feeling of "being calm" or "being in the moment." The map has three coordinates: **(a) tracelessness — no discrimination has yet been stamped, no direction carved; (b) lucidity — awareness is fully awake, not blank or sleepy; (c) immediacy — it is always *here*, never a destination to be reached by doing something.**
1. The notification on your phone
The phone buzzes. A name, a snippet of text appears. Before you can read the words, before any meaning forms — there is a flicker, maybe a tenth of a second, in which the screen is just a lit rectangle with shapes on it. That flicker is the *wàn lǐ wú cùn cǎo* (ten thousand miles, not an inch of grass). No thought, no judgment, no "who is this," no "should I check it," no "I hope it's good news" or "not now" — none of that has yet pressed itself into a recognizable form. The mechanism is turning, the seal is not yet pressed (*jī suī zhuǎn niǔ, yìn wèi chéng wén chù*).
Then the stamping begins. A word catches. A sentence forms. The old story — "this person always…" or "this is going to ruin my evening" — cuts in. By the time you've decided to open the message, the field is already dense with grass.
The walking-through here is not "I should have stayed in the flicker longer." That very instruction is already a new stamping, a new grass. The "going" (*qù*, 去) that Dongshan asks about is not a *staying* in the flicker either. It is something that has to do with how the *already-here* tracelessness and the *unavoidable* stamping relate — without one of them being suppressed for the sake of the other.
2. The harsh email at work
You open a message. The first sentence is sharp, possibly unfair. Before the wave of *this is unjust / they don't understand / I need to defend myself* — and just as important, before the counter-wave of *I should be the bigger person / let me draft a measured response* — there is the reading itself. The shapes of the words, their sounds in your head, their weight. That is the place with no grass.
The lucidity (*xīngxīng*) here is not "calm." Calm is a *state*, a position one tries to hold, and holding it is itself a stamping. The lucidity is what is already happening in the reading: you have not yet been thrown into the story, the seal is not yet pressed. The stillness (*jìjì*) is not numbness — you actually receive the words, you actually feel the weight. But the *trace* — the "this means *I am*" or "this means *they are*" — has not yet been inscribed.
The contemporary practitioner who tries to apply this often makes the mistake of *suppressing* the reaction. That is not the teaching. The teaching is the *prior* openness, the field in which the reaction is about to occur, but hasn't yet. This is why *"作麼生去"* (how do you go?) is the koan: the moment you turn the "traceless" into a method for getting through emails, you have already cultivated a new patch of grass.
3. The partner who says the wrong thing
You are in an intimate relationship. Your partner says something that hits a nerve. In the half-second before the old tape begins — *you always do this / here we go again / they don't care* — there is just the sound of their voice, the look on their face, your own chest rising and falling. The grass has not yet sprouted. The three times are cut off, the six gates empty (*sān jì duàn liù mén kōng*).
This is *not* "mindfulness" in the popular sense of "observing your reaction." Observing is already a second move. It is the *first* reception, which the second move then comments on. The "ten thousand miles without grass" is the first reception, the *qù* (去) that Dongshan asks about is the second move's question: how do you *go* there, how do you act, how do you live, when the field is already this?
The relationship question that follows is not "how do I stay in that traceless moment?" but "what is the right action when, in fact, the traceless moment and the reactive moment are *both* here, all the time?" This is where Hongzhi's *"大功一色"* (the great function is one color) and *"全超無影迹，不墮古今機"* point: action that doesn't fall into any device, that doesn't sit in either "react" or "don't react."
4. The crying child
A child is crying. Before the cascade — *what's wrong / I'm a bad parent / I should have noticed / I need to fix this / they need to stop* — there is the sound. The child's face. The room. Nothing yet, in the sense of *no judgment, no story, no past or future*. Ten thousand miles, not an inch of grass.
The classic error, again, is to try to *stay* in that pre-judgmental hearing. The very attempt to stay there is a new kind of judgment, a subtle self-cultivation: "I am being a present parent." This is the "grass" that Shishuang is warning about when he says *"出門便是草"* — even the most sincere step toward this "place" is already a step into grass. Dayang's counter-*"不出門亦是草漫漫地"* is also true: even *not* trying to stay there, even doing nothing special, the mind is already thick with grass.
The child still needs to be held. The "going" is not a bypassing of the holding.
5. The morning commute
You are walking, looking at nothing in particular. The street is loud, the air is cold, the coffee is hot in your hand. The city is doing its city thing. There is no "I" yet, in the sense of *a person with a to-do list heading toward a stressful day.* There is just walking, just coffee, just cold air. Ten thousand miles, not an inch of grass.
This is the moment contemporary people sometimes recognize through practices like running, swimming, or walking meditation. It is the closest many get to the teaching. But even here, the moment one says "I am having a meditative experience" or "this is the present moment" or "I should try to live like this all the time" — grass. Hongzhi's *"善惡如浮雲，起滅俱無處"* and *"生佛立不得"* point to the fact that even "good" and "bad," even "Buddha" and "ordinary being," have no standing here. So the very instinct to grade the experience ("this is a good spiritual state") is precisely what is being undone.
6. The mapping that the contemporary mind most often gets wrong
- Not "no thoughts" but "before the thought": Suppressing thoughts is not the teaching; the teaching concerns the *prior* openness, the *qù* (去) before any direction is taken. - Not "being calm" but "the field that hosts calm and storm equally": Calm is one more stamping if held as a state. The teaching is the *unformed* in which calm and storm both have their place. - Not "a feeling" but a structural pivot: It's tempting to think of this as a subtle inner experience. The classical teaching is more austere: a *place* (處) where the very mechanism (*jī*, 機) of stamping is happening but has not yet produced a recognizable pattern (*yìn wèi chéng wén*, 印未成文). - Not a destination: This is what the koan structure of 去 / 作麼生去 is breaking. The instruction is to *go*, but any "going" you can conceive is already grass.
Why Contemporary People Need This
The condition of contemporary life is, almost by definition, a condition in which the stamping of traces never lets up. The smartphone is a stamping machine, social media is a stamping machine, the modern workplace is a stamping machine, even our leisure is a stamping machine ("how do you feel about this film?" "rate your experience"). The brain itself, as contemporary neuroscience describes it, is a *prediction engine* — it generates expectations, compares them to incoming data, updates, and stamps, in a loop that rarely pauses. Predictive processing (the brain-model associated with figures like Andy Clark and Jakob Hohwy) describes, in secular language, something that Chan noticed centuries ago: that *recognition* is rarely the *first* event. There is always a prior move.
What the Chan teaching offers is not a better strategy for managing the stamping (that is more stamping). It offers a *turning toward the unformed* in the midst of the stamping. The point is not to get rid of the phone, the email, the partner, the child, the commute. The point is to live in a way that *knows the unformed* as the field in which all of this occurs.
The need, in our moment, is acute for a specific reason: we have an unprecedented ability to *control the inputs* (curate our feed, choose our news, mute the voices we don't want to hear), which has led to an unprecedented *unawareness of the stamping itself*. The contemporary person often cannot tell the difference between "what I notice" and "what I have been trained to notice." This is a deep, structural blindness. The Chan teaching of "no grass" is, among other things, a way of *exposing the unseen grass* — the conditioned tracings that have become invisible precisely because we have not learned to notice them.
There is also, increasingly, a sense of *exhaustion*. The stamping is not only cognitive but somatic. Bodies are tired. Nervous systems are over-activated. The popular turn toward meditation, breathwork, "presence" is partly a response to this exhaustion. The Chan teaching meets the exhaustion but does not flatter it: it does not promise a "place of rest" you can reach by going somewhere. *"出門便是草。不出門亦是草漫漫地。"* The exhaustion itself, however real, is a kind of grass. The rest, the tracelessness, is not the opposite of the exhaustion; it is the field in which the exhaustion and the wakefulness appear together.
The contemporary resonance with the *dual* teaching — *jìjì* (寂寂) and *xīngxīng* (惺惺) — is also worth noticing. Both popular meditation culture and certain strands of "mindfulness" tend to emphasize the *stillness* side and quietly drop the *wakefulness* side. The result is often a kind of soft, well-intentioned dullness — pleasant, harmless, and spiritually inert. The Chan insistence that *xīngxīng* is not optional — that "no grass" is *also* a kind of seeing through (*zhàodépò*, 照得破) — is a quiet rebuke to that soft dullness. It says: the resting is not enough; the seeing-through is part of the resting.
Common Misreadings and Clarifications
1. "It is a place, you have to get there." This is the literal misreading. Shishuang and Dayang, both quoted in the *Guanglu*, dismantle it. There is no-where to go. *Qù* (去) is not a movement through space; it is a turning within, or rather, a turning that is not yet a turning toward anything in particular.
2. "It is nothingness / blankness / unconsciousness." This collapses the *xīngxīng* (惺惺, lucid wakefulness) side. Hongzhi is explicit: *"惺惺照得破，寂寂體得到"* — both. Blankness is a kind of grass too, only it is the grass of torpor. *"善惡如浮雲，起滅俱無處"* does not mean there is no awareness; it means that good and evil have no fixed abode within the awareness. The awareness itself is fully awake, simply not fastened to anything.
3. "It is a high spiritual state to be achieved." Hongzhi's *"功亡不知位"* (when the function is lost, no position is known) specifically rules this out. The very act of grading experience is grass. *Wànlǐ wú cùn cǎo* is not the highest rung of a ladder; it is the *ground* of the ladder. (Chan has its own idiom for the misuse of "rankings" — it's called "measuring the sea with a bushel," itself a piece of grass.)
4. "It is about having no thoughts." This collapses the *jìjì* (寂寂, traceless stillness) side and also gets the structure wrong. The teaching is not the suppression of thought; it is the *prior* openness, the field before the seal is pressed. Trying to "have no thoughts" is a *very active* stamping — a stamping of the "no-thoughts" state. *"心念纔萌便成流注"* (the moment a mental stirring arises, it has already become a flowing trace) — the question is not "how to stop the stirring" but "what is the field in which the stirring and the no-stirring are not yet distinguished?"
5. "Going to a retreat, a monastery, or a nature spot will get you there." Shishuang's *"出門便是草"* is exactly about this. The retreat is grass. The monastery is grass. The mountain cabin is grass. Not because these places are bad, but because the very project of "going to find the place" is itself the stamping that constitutes the grass. *Wànlǐ wú cùn cǎo chù* is not geographically locatable.
6. "It's the same as 'being in the flow' or 'being in the zone.'" Flow states are real and valuable, but they are *states* — they have a beginning, an end, conditions that produce them, and (often) a trace of self-satisfaction afterward. *Wànlǐ wú cùn cǎo chù* is not a state at all, in the sense of a fluctuating experience; it is the *unformed* that hosts all states. Hongzhi's *"一絲不沾綴，一糝不停留"* (not a single thread of attachment or a grain of holding-back) points to something more radical than any pleasant state.
7. "It is escapism — a way of not dealing with reality." This is perhaps the most common contemporary misreading, especially among thoughtful people who have encountered Buddhist-flavored language in self-help contexts. Hongzhi's *"色轉不見身"* (when the form shifts, no body is seen) does *not* mean the body disappears. It means that when the *stamping* of "body" as a fixed category is no longer operative, the body is lived differently — more directly, more responsively, without the layered commentary. This is not withdrawal from the world. It is, if anything, the *most* direct contact with the world — the contact that has not yet been filtered through the stories we tell about the world.
8. "If good and evil don't stand, then anything goes." *Wànlǐ wú cùn cǎo chù* is not moral relativism. *"不思善不思惡"* (not thinking good, not thinking evil) is famously the moment *before* Huineng's enlightenment, after which he immediately says *"菩提本無樹"* (bodhi is originally not a tree). The non-standing of good and evil is the field in which genuine good and genuine evil can be discerned freshly, without the dead weight of habit. The teaching of "no grass" is, in this sense, deeply moral — not in spite of suspending the categories, but precisely *because* of it.
One Final Note on How to Hold This
The classical teaching does not end with a definition. It ends with a *question* — *"作麼生去?"* — which is not a request for an answer but a device for exposing the questioner's assumptions. To read *wànlǐ wú cùn cǎo chù* as a concept to be understood is, by the teaching's own logic, to grow more grass.
So the invitation is not to understand it but to notice, perhaps many times today, the *already-here* of it: the moment the email is just shapes, the moment the child is just a sound, the moment the street is just walking, the moment the partner's face is just a face. And in noticing, to notice also that the *noticing* has a way of becoming a new stamping if you hold onto it.
That is why *"全超無影迹，不墮古今機"* is the deepest of Hongzhi's glosses: completely transcending, no shadow and no trace, not falling into any device of past or present. The "going" is something one *does* without doing, *knows* without knowing, *is* without being anything in particular. Hongzhi would not say this is mysterious. He would say it is the simplest thing in the world — and that is exactly why no one can find it.
