There is a Chan (Zen) saying — born from a koan attributed to Dongshan Liangjie (洞山良价) — that sounds, on first hearing, like a description of paradise: a place free of cold and free of heat. A monk asks how to avoid the seasons when they come. Dongshan asks why he doesn't simply go to the place where there is no cold or heat (*無寒暑處*, *wú hán shǔ chù*). The monk, taking the bait, asks where that place is. Dongshan answers: "When it's cold, cold kills the ācārya; when it's hot, hot kills the ācārya." 寒時寒殺闍梨，熱時熱殺闍梨。
That answer is not a riddle. It is the entire teaching. To understand *wú hán shǔ chù* is to understand why this answer — which sounds like it gives nothing — gives everything.
What this concept is saying
1. The question that is asked before the answer
Every human being, in some form, asks Dongshan's monk's question. When suffering arrives — when the body hurts, when a relationship ends, when a job dissolves, when an aging parent is failing, when the news is unbearable — the instinctive posture is: how do I get out of this? Where is the room, the practice, the medication, the technique, the year, the country, the spiritual state, the frame of mind where this isn't happening to me? The monk's question is the human question: *how do I avoid?*
Dongshan's first move does not deny the question. He intensifies it. He says: there is such a place; go there. The monk, predictably, takes this as a hint, a direction, a map coordinate, and asks *where*. This is the second human mistake — believing that the answer to "how do I get out" is a place that one can then point to.
2. What Dongshan actually says — and what he does not say
Dongshan's answer is not "there is no place." It is also not "the place is right here, in this very moment, so relax." Both of these are the kind of smooth, packaged teachings that contemporary spiritual culture loves. Dongshan gives neither. He says: *寒時寒殺闍梨，熱時熱殺�梨* — "when it's cold, cold kills the ācārya; when it's hot, hot kills the ācārya."
Two things to notice about this sentence.
First, the verb *殺* (kill) is not soft. It is not "cold touches the ācārya," or "cold surrounds the ācārya." It is "cold kills the ācārya." The encounter is total. The classical sources preserve this verb across both Yuanwu Foguo's (圓悟佛果禪師) and Dahui Pujue's (大慧普覺禪師) records — 寒殺, 熱殺 — and never substitute a gentler word. The point of the concept is not a polite encounter with discomfort; it is a fully lethal one.
Second, there is no surviving ācārya standing apart from the cold/heat to whom the cold/heat is happening. The grammatical subject of "cold kills the ācārya" is not "cold, acting upon a separate person, kills him." It is more like: *what was being called the ācārya is precisely what cold is doing.* There is no ācārya left over after the killing. This is why the term *無寒暑處* is not pointing to a refuge *outside* cold/heat, but to what remains when the attempt to be somewhere else in relation to cold/heat collapses.
3. The two records, the two emphases
The two great Chan masters who recorded and extended this koan do not give the same gloss.
Yuanwu Foguo treats it primarily as a model of *機用* (jī yòng) — the functional, dynamic operation of Chan. He is not interested in giving an abstract doctrinal explanation. He surrounds the koan with images of operations that cannot be tracked: 盤走珠珠走盤 — the plate runs the pearl, the pearl runs the plate (each defines the other; neither can be located separately); 羚羊掛角無蹤跡，獵犬遧林空踧踖 — the antelope hangs its horns so there are no tracks, the hunting dog circles the forest in vain. The teaching is *not a doctrine* you can hold, but a *function* you can either enter or not. He adds: 法界不容身 ("the Dharma realm does not accommodate a body"), 聖智離言說 ("holy wisdom is beyond words"), 坐却意根無動轉處 ("sit and block the mind-root so there is no place it can move"), 塞却咽喉無吐氣處 ("block the throat so there is no place to exhale"). These are not definitions of the place; they are instructions not to *try to lodge yourself anywhere* in the field of consciousness and sensation. In a separate passage he writes, in the middle of actual cold: 大家在箇裏，滴水滴凍 — "everyone is right here in it, the dripping water freezes." When asked 作麼生是不離當處底一句 ("what is the phrase that does not leave the present place?"), he answers: 鶴飛千尺雪，龍起一潭氷 — "the crane flies through a thousand feet of snow, the dragon rises in a pool of ice." Snow, ice, and the cold environment are *the response*. They are not what the response escapes.
Dahui Pujue develops the teaching into two complementary sides. He pairs the Dongshan koan with another koan in which an old master tells a monk to seek refuge *inside* a cauldron of boiling water and a furnace of coals (鑊湯爐炭裏回避). He judges these as two aspects of the same thing: 一人在寒暑裏垂手,一人在寒暑外垂手 — "one person extends a hand *inside* cold/heat, one extends a hand *outside* cold/heat."
- The one inside cold/heat: 不見有寒暑之相 — "does not see the marks of cold and heat." This is not numbness or denial. It is the recognition that cold and heat, when not abstracted into objects one relates to, have no independent "form" standing over against a self. - The one outside cold/heat: 通身是寒暑 — "the whole body *is* cold and heat." The body is no longer set over against the condition; the body is the condition. There is no inside/outside.
Dahui insists these are *two sides of one thing*, not two different achievements. And — this is crucial — he never names a *third* option: a place set apart from both.
His operative technical term is *不被寒暑之所遷* — "not relocated by cold and heat," paired with *不被生死之所轉* — "not turned by birth and death." Note carefully: not "消滅寒暑" — not "cold and heat are destroyed." The cold and heat are still there. The person is not *moved* by them. 遷 (qiān) is the verb for migration, displacement, being shifted from one's dwelling. The teaching is not about what is happening to the senses; it is about whether the sensing is relocated.
He generalizes this to everything: 寒則普天普地寒,熱則普天普地熱 — "when it's cold, cold throughout heaven and earth; when it's hot, hot throughout heaven and earth." There is no patch left, no neutral corner. Then, in a passage of exhausting enumeration: 冬寒夏熱,夜暗日明,內外中間,東西南北,不曾移易增減一�毫許 — "winter cold, summer heat, night dark, day bright, inside-outside-middle, east-west-south-north — none has ever changed or decreased by even a tiny bit." He then pushes further, dismantling even the speaker and the hearer and the very category "不可得" (the ungraspable) as another object, and lands on: 無說處是真說,無聞處是真聞 — "the place of no speaking is true speaking; the place of no hearing is true hearing." The teaching cannot be taught as a doctrine any more than the cold can be pointed to as something outside cold.
4. What the concept is — precisely
Stripping the two records together, *wú hán shǔ chù* is the recognition that:
- The place one tries to find *outside* cold/heat is a fantasy, and the search for it is itself the cold/heat. - Cold/heat are not eliminable, not escapable, and not even nameable as objects separable from oneself. - The freedom the term points to is *not being relocated* by cold/heat — not the absence of cold/heat, but the absence of *being moved from one's dwelling by them*. - This non-relocation does not require a special state. It is what remains when the search for a special state has been given up.
The classical sources pair this term with related phrases in the same conceptual neighborhood — "雖居四相,而四相羅籠不住" ("though dwelling among the four marks, not caged by them"), "無位真人" ("person of no fixed position"), "非如非異" ("neither like nor unlike"), "非色非心" ("neither form nor mind"), "透過荊棘叢林,便居常寂光土" ("passing through the bramble thicket, one abides in the ever-quiet light-ground"). The sources explicitly note these are *background phrases*, not direct glosses on the koan — which means *wú hán shǔ chù* is its own term, with its own precise job, and not to be flattened into any of these other formulations. Its job is precisely the cold and the heat.
5. Where this concept sits in the wider path
*Wú hán shǔ chù* is not a preliminary concentration practice, not an ethical training, not a method for getting through difficult feelings. It is a Chan technical term operating at the level of *見性* (jiàn xìng) — seeing one's nature — and freedom from *二相* (èr xiàng), the dualistic marks by which experience is split into self and other, into inside and outside, into here and there. Its diagnostic value is that it cuts through the most persistent form of dualism: the assumption that *my real self* is somewhere other than *this experience*. Most contemporary spiritual language, even when it sounds non-dual, is secretly dualist in this way — it preserves a self that is doing the witnessing, the practicing, the accepting, the transcending. The koan refuses to allow that.
Life walkthrough
It is one thing to hear this. It is another to walk it. Let me walk it through several ordinary scenes of contemporary life. In each one I will use the classical definition precisely, and at the end flag the place where most modern people silently swap the teaching for something else.
Walk 1: The cold — grief after a loss
Someone you love has died. You are at the funeral, or a year later at the empty kitchen. The cold is real — physical, social, internal. The contemporary toolkit offers you: distraction, grief counseling framed as "processing," reframing ("they're in a better place"), spiritual bypassing ("I'm at peace with it"), endurance ("time heals"), future focus ("you'll feel better soon"). Each of these is a version of *going to the place without cold*. Each is a version of Dongshan's monk asking *where is that place*.
The classical response is not any of these. It is: the cold is here, you are in it, the dripping water is freezing. *鶴飛千尺雪,龍起一潭氷* — the crane flies through thousand-foot snow; you cannot stand anywhere but inside the snow. *不被寒暑之所遷* — the cold has not gone anywhere, and neither have you. You are not "above" the cold; you are not "coping with" the cold; you are not "processing" the cold. The cold is what is happening, and what is happening is what you are.
The misreading to flag: people often think the teaching means "feel your feelings without resistance." That is closer, but still too dual — it keeps a "you" who is feeling. The teaching is sharper: there is no feeling subject distinct from the feeling. The crane, the snow, the flight — one event.
Walk 2: The heat — being overwhelmed at work
It is late, you have answered the tenth message of the evening, your chest is tight, your partner has stopped asking you to come to bed, your body is wired. The heat is everywhere. The contemporary toolkit: "set boundaries," "have a self-care practice," "meditate," "go for a walk," "log off," "take a mental health day." Some of these are sensible; some are not. The classical question is: are any of these the *place without heat*?
Dongshan's answer: when it's hot, hot kills the ācārya. 通身是寒暑 — the whole body is heat. The question is not whether to leave the heat (you may, the world has its rhythms), but whether the leaving is itself the heat relocating you. The person who logs off only to scroll Instagram in bed has been relocated by the heat, not freed from it. The person who meditates only to feel more frantic afterwards has used meditation as a heat-exit that did not work. *不被寒暑之所遷* — the freedom is not in changing the temperature, but in no longer being moved by it.
The misreading to flag: this is often read as "be present with discomfort" or "don't numb out." Both of those still keep a self who is being present. The teaching is more austere: there is no self who is being present. There is only the heat, fully, without a witness left over.
Walk 3: The chronic — long illness, ongoing relational difficulty, the season that won't pass
This is where the concept is sharpest. Some colds and heats do not pass. Chronic pain. A marriage in slow trouble. A child's long illness. A job market that will not yield. You cannot find a place without these. The structure of "escape" is unavailable to you. You are inside the cold/heat structurally, not by choice.
Here the classical teaching becomes a precise instrument. *冬寒夏熱,夜暗日明,不曾移易增減一絲毫許* — winter cold, summer heat, night dark, day bright — none has ever changed or decreased by even a tiny bit. The chronic is not going to change. The teaching is not going to change it. But — and this is the only thing that matters — you can stop being *relocated* by it. You can live inside the chronic without the chronic having the vote on where you actually are.
The misreading to flag: contemporary "acceptance" language often smuggles in a self that accepts. "I have accepted my illness." The "I" that has accepted is then relocated by the acceptance, and the acceptance is itself another cold/heat. The teaching here is closer to: the chronic illness is the weather; you are the weather; there is no separate "you" to whom acceptance can happen. This is why Dahui ends his passage not with "acceptance" but with 無說處是真說 — even the saying of it is not separate from the unsaying.
Walk 4: The algorithmic cold/heat — scrolling, feeds, dopamine loops
A scene increasingly common: you open your phone to look up one thing. An hour later you close it. The feed has given you variable reward — small heats of pleasure, small colds of outrage, small chills of envy, small burns of inadequacy. The whole system is a climate. The contemporary toolkit: "digital detox," "mindful phone use," "turn off notifications," "use grayscale." Useful, partial.
But the more precise classical question: is the scroll really external to you? 通身是寒暑 — is your whole body actually the scroll, right now? Are you scrolling, or is the scroll happening as a kind of thinking-with-fingers-and-eyes? When the cool blue light hits your retina, the cold/heat is already inside. When you reach for the phone again after deciding not to, you have been *relocated*. The freedom is not in never being scrolled; it is in the scroll not being able to move you out of where you are.
A caveat I want to mark explicitly: contemporary cognitive science has documented that variable-ratio reward schedules do produce compulsive patterns of attention capture; this is empirically real. But cognitive science describes the *mechanism* of capture; it does not, on its own, describe what it is like to *not be captured*. Chan points to the latter. The two can be spoken together carefully, but they are not the same project. The mechanism can be altered; the relocation is what Chan addresses.
Walk 5: The cold between people — intimacy, conflict, parenting
Two people who love each other are in a hard conversation. The room is cold. Contemporary scripts: "communicate your needs," "use 'I' statements," "hold space," "name your emotions," "seek couples therapy." Useful, but note the structure: every one of these imagines a self that is doing the communicating, holding, naming, seeking.
*天寒人寒,大家在箇裏,滴水滴凍* — "when it's cold and people are cold, everyone is right here in it, the dripping water freezes." The cold between people is shared cold. There is no warm room next door; both people are inside the same freezing water. The temptation is to look for the warm room — "if only they would apologize, if only I could articulate better, if only we could afford the right therapist." Dongshan: the warm room is not the warm room. There is only this room, this cold, these two cranes in the snow.
With children: the same, more acute. A child is suffering; a parent's instinct is to take the child somewhere without the cold. Sometimes that is right — a sick child to a doctor. But the deeper teaching: the child is in cold; the parent is in cold; the cold is not two colds. *鶴飛千尺雪* — the crane flies through thousand-foot snow. The flight and the snow are one event.
The misreading to flag: people often read this as "don't try to fix things" or "don't try to help." That is a misreading. The teaching is about *how* one fixes things, not whether one does. To act from inside the cold, fully relocated-by-nothing, is very different from to act from outside the cold while imagining oneself inside it.
Walk 6: The slow heat — aging, the body that won't keep up
The contemporary condition of mid-life and beyond: the body gives signals it did not give before. Heat in the joints. Cold in the hands. Memory that fails. The contemporary toolkit: optimize, train, biohack, supplement, consult. The classical question: is the body that is changing, you? Or is the body that is changing, weather?
不被寒暑之所遷 — the aging body does not relocate you. You were never located in the joints, in the memory, in the mirror. You are not "in" the body the way a passenger is in a car. The cold/heat of aging is happening; the question is whether you will be moved by it. Some of the most striking old people in life are those who are fully inside the cold/heat of their own aging, not performing against it and not collapsed by it. Yuanwu: 雖居四相,而四相羅籠不住 — "though dwelling among the four marks, not caged by them." The body is one of the four marks. You can dwell in it without being caged by it.
Why contemporary people need this
The contemporary world is, structurally, a machine for relocating people. Few other historical periods have engineered as many refined exits from the present moment. The architecture of contemporary life — feeds, streams, on-demand everything, the entire wellness and therapy industry, even much of contemporary meditation culture — is in many places a sophisticated continuation of Dongshan's monk's question: *how do I get out of this?*
The result is a kind of chronic relocatability. People are constantly being moved by cold/heat that they have not realized is not, in fact, taking them anywhere new. The person who scrolls to avoid feeling has been relocated by the scroll. The person who reframes grief has been relocated by the reframing. The person who performs equanimity has been relocated by the performance. The person who "takes a mental health day" and is more anxious on the mental health day than on the work day has been relocated by the day itself.
*Wú hán shǔ chù* does not add another technique to this list. It does the more radical thing: it points out that the search for a place without cold/heat *is* the cold/heat, and that the freedom it points to is not another place but the non-relocation that remains when the search has been given up.
A second contemporary resonance: contemporary culture is unusually prone to *dualistic witnessing*. The entire genre of "observe your emotions," "watch the breath," "notice the thought," even much of mindfulness, operates from a structure in which there is an observer and an observed. This is a refined form of the dualism Chan spent centuries dismantling. *Wú hán shǔ chù* refuses the witness. 通身是寒暑 — there is no one left over to witness. The contemporary person who, despite all their practice, still feels that something in them is *managing* their experience, is exactly the one this concept is for.
A third: contemporary people are unusually prone to *escapism dressed as transcendence*. "I'm in a higher vibration now." "I've ascended beyond that." "I don't do anger anymore." These are exactly the *別求回避之所* — separately seeking a place of avoidance — that Dongshan refuses. The cold/heat is still happening; the "higher vibration" is just a colder room.
In all three cases, what the contemporary person needs is not another room, but the recognition that no other room is available — and that this recognition is not grim news but the very thing the term points to.
Common misreadings and clarifications
I want to spend space on this, because the misreadings of this concept are particularly persistent and particularly contemporary.
Misreading 1: Numbing / dissociation. "The place without cold or heat" gets read as a place where nothing is felt. This is the opposite of what the sources say. *寒殺* and *熱殺* are lethal encounters. The teaching requires full sensory presence. Dissociation is being relocated by the cold/heat *into* numbness; it is not non-relocation. The person who cannot feel grief is more relocated by grief, not less.
Misreading 2: Stoic indifference. Stoicism wants the sage to be unmoved by externals. *Wú hán shǔ chù* wants the person to be fully inside the externals, not unmoved by them. The classical term is *不被寒暑之所遷*, not *不受寒暑之感*. The cold/heat still arrives, fully. You are not relocated. This is not stoic *apatheia*; it is something the Stoics did not have a category for.
Misreading 3: "Mindfulness" as a witnessing stance. When mindfulness is taught as "observe your thoughts and feelings from a calm center," it preserves the very dualism Chan refuses. 通身是寒暑 — there is no calm center observing. There is cold/heat. The "observer" is another object inside the field. This is one of the most common contemporary misreadings, because it is dressed in the language of Chan and even of Buddhism generally. Yuanwu's warning is precise: 塞却咽喉無吐氣處 — block the throat so there is no place to exhale. The teaching is not about finding a calm place to observe from. It is about there being no place to observe from.
Misreading 4: Spiritual bypassing. "I'm beyond anger." "I've transcended need." "I'm at a higher vibration." These are exactly the *別求回避之所* that the monk in the koan is asking for. The cold/heat is still happening; the "transcendence" is just a colder, more polite room. The classical sources repeatedly warn against this — 不見有寒暑之相 does *not* mean "I have no cold/heat." It means cold/heat have no separable *form* standing over against me. Big difference.
Misreading 5: Toxic resilience. "Just push through." "Stay strong." This is being maximally relocated by the cold/heat — used *by* it — not non-relocation. The classical teaching is not toughness. The classical teaching is the opposite of toughness. The crane flies through thousand-foot snow; it does not "push through" the snow. The flight is the snow; the snow is the flight.
Misreading 6: Hedonism / heat-seeking. The contemporary version: live only in the heat, chase intensity, refuse the cold. Also a misreading. The concept includes cold and heat equally. 冬寒夏熱 — winter cold and summer heat are both affirmed. The teaching is not "stay in the heat"; it is "neither heat nor cold relocates you." The person who lives only in intensity is maximally relocated by intensity.
Misreading 7: Nihilism. "Nothing matters anyway." This is "不可得" taken as a position rather than a recognition. Dahui dismantles this when he makes "不可得" itself ungraspable. The teaching is not a stance; it is what is left when no stance can be maintained.
Misreading 8: The literal English reading. "The place without cold or heat" — read in English — sounds like a temperature-controlled environment. The classical Chinese is doing the opposite of what the English sounds like doing. The phrase names the very thing it appears to deny. This is the most common misreading of all, because it is built into the surface of the term. The teaching only arrives when one realizes that *無寒暑處* is not a place characterized by the absence of cold/heat, but a recognition in which the absence of *the search for such a place* is what is meant.
Misreading 9: Reifying the term itself. The most subtle misreading: turning *wú hán shǔ chù* into a stage, an attainment, a level. Dahui's dismantling at the end of his long passage — making even "不可得" itself ungraspable — is specifically designed to prevent this. The moment *wú hán shǔ chù* becomes a stage to attain, it has become another cold/heat to be relocated by.
*Wú hán shǔ chù* is therefore not a destination. It is not a meditation. It is not even, strictly, a teaching one can hold. It is the recognition, available at any moment, that the cold/heat one is in *is not taking one anywhere* — because there is no "one" separable from it to be taken anywhere. The place without cold or heat is not somewhere else. It is the place one already is, when one has stopped looking for somewhere else.
Dongshan's sentence, repeated across the centuries in the records of Yuanwu and Dahui, is not a riddle to be solved. It is a place to stop looking for the place. 寒時寒殺闍梨,熱時熱殺闍梨 — when it's cold, cold kills the ācārya; when it's hot, hot kills the ācārya. There is no ācārya left after this sentence to go anywhere else. That is the place without cold or heat.
