一、这个概念在说什么 — What This Concept Is About
The most compact classical statement is from 《古尊宿語錄》(Gǔ Zūnsù Yǔlù, "Recorded Sayings of Ancient Worthies," Chan/Zen record, X1315):
「但離妄緣，即如如佛。」 "Just let go of delusive conditions, and it is the Suchness-Buddha."
「但盡妄緣，即如如佛。」 "Just exhaust delusive conditions, and it is the Suchness-Buddha."
A first-pass reading might think: "I should somehow distance myself from illusory things, and then I'll be a Buddha." That is almost the opposite of what the text is saying. 如如佛 is not a goal achieved by becoming something different. It is what is already manifesting whenever the conditions that obscure it are no longer operative. The text does not say "go get the Buddha" or "transform into the Buddha." It says: when the obscuring conditions come to completion, the Buddha is exposed — and it has always been there.
The classical passage builds this from four angles that should be held together rather than collapsed:
1. 離盡妄緣 (Lí jìn wàngyuán — Letting go of / exhausting "delusive conditions")
What is a 妄緣 (wàngyuán, "delusive condition")? It is not "external objects" and it is not "raw emotions." It is the active engagement of mind by which it fabricates conditions — the momentum of grasping, judging, projecting, comparing, concluding. The word 緣 (yuán, "condition") points to the relational activity of mind by which it weaves itself into objects and conclusions. 妄緣 is that weaving under the assumption that the conclusions are real.
「離」 and 「盡」 are two different verbs, used on purpose. 離 (lí) is to step back from; 盡 (jìn) is to bring to completion, to exhaust, to let finish. Together they cover both the immediate letting-go and the long letting-finish. The text uses both forms — 「但離妄緣」 and 「但盡妄緣」 — so this is not read as a single dramatic act of suppression. It is a wearing-out.
2. 聖凡情盡 (Shèng fán qíng jìn — The sentiments of "sage" and "ordinary" exhausted)
「不用愛聖，聖是空名；不用厭凡，凡是妄立。聖凡情盡，體露真常。」
Here the text takes the next layer apart. The two most seductive positions for a serious practitioner are: "I love the sage, I want to become saintly" and "I am disgusted with the ordinary world, I want to transcend it." Both are still running on the same underlying current — the assumption that sage and ordinary, sacred and profane, are real categories that divide reality.
The text is precise. 「聖是空名」 — "sage" is an empty name; 「凡是妄立」 — "ordinary" is a delusively established category. These labels are not facts about the world; they are positions taken by a mind that is still sorting experience into hierarchies. When the very sentiment (情, qíng) that arranges things into sage vs. ordinary comes to rest, what is exposed is 「體露真常」 — the body (體) reveals (露) what is truly constant (真常). The text pairs this specific phrase 「體露真常」 alongside 「如如佛」 as two names for the same thing.
This is not a moral instruction like "stop trying to be good." It is the recognition that the entire project of "becoming saintly" is itself a way of being run by preference and aversion. The constant is not something that becomes available once you are sufficiently saintly or sufficiently detached; it is what remains when the up-and-down preference structure no longer runs.
3. 迷悟一漢 (Mí wù yī hàn — Deluded and awakened are the same person)
「迷也祇是者漢，悟也祇是者漢，不可別有。」 「向前迷底便是即今悟底，即今悟底便是向前迷底。」 「不改舊時人，祇改舊時行履處。」
This is the most counter-intuitive move in the text and the easiest to misread. It is the text's way of saying: there is no "old deluded you" replaced by a "new awakened you."
「者漢」 (zhě hàn) — "this fellow," "this very person" — is the rough, almost vernacular Chan term for the ordinary human being standing right here. The text insists: in delusion it is still this person; in awakening it is still this person. 「不可別有」 — there cannot be another.
「向前迷底便是即今悟底」 — the basis on which one was deluded before is exactly the basis on which one is awakened now. 「即今悟底便是向前迷底」 — and the basis on which one is awakened now is exactly what was the basis of one's earlier delusion. This is not wordplay. It is a logical refusal of the view that awakening is an exchange — that you trade in your confusion for some higher substance. If awakening were a new thing, a new entity, then it could not be the basis of the previous confusion, because the previous confusion had a different basis. Therefore, awakening cannot be a new thing.
「不改舊時人，祇改舊時行履處」 — not changing the person of old times, only changing the old 行履處 (xínglǚ chù), the "place where one walks" — i.e., the manner of one's conduct and going-about. The person is continuous. What changes is the way they go about things.
So when the text says 「離盡妄緣，即如如佛」, it does not mean: the old you leaves and a Buddha emerges. It means: in the same person, when the old way of going-about is exhausted, the Buddha that has always been the basis of that very person is exposed.
4. 心佛不異與法身實相 (Xīn Fó bù yì yǔ fǎshēn shíxiàng — Mind-Buddha non-duality and the Dharma-body reality)
「汝心是佛，佛即是心；心佛不異。」 「若離於心，別更無佛。」
Here the text anchors the teaching. 心 (xīn, mind / heart-mind) and 佛 (Buddha) are not two things that are "connected" or "resemble each other" — they are the same. The text does not say "your mind contains Buddha-nature" or "your mind can become Buddha"; it says the more radical thing: 「心佛不異」 — mind and Buddha are not different. 「汝心是佛，佛即是心」 is symmetrical on purpose: each direction is denied as a separate path.
「若離於心，別更無佛」 — if you set them apart, apart from mind there is no Buddha at all. There is no Buddha over there to fetch; no Buddha separate from this very mind to be acquired. This is what 如如佛 ultimately points to — not a Buddha one finds, but a Buddha-as-such-ness already here.
「三身一體，一體三身」，第一是「法身實相佛」。
The text presents the Trikāya (三身, the three bodies of a Buddha — 法身 dharma-body, 報身 enjoyment-body, 化身 transformation-body) as "three bodies one body, one body three bodies." It picks out the first one, 法身實相佛 (Fǎshēn shíxiàng Fó, "Dharma-body Reality-Buddha"), as its primary referent for 如如佛.
This 法身 is described in very specific terms: 「不明不暗」 — "neither bright nor dark." Why? Because 明 (brightness, clarity) and 暗 (darkness, obscuration) are themselves categories that arise within the field of experience; they belong to the play of phenomena. A reality that is truly original cannot be defined by any of the pairs that show up inside experience.
「實相」只是相對於虛而得名，其本來「並無一切名目」。
"Reality" (實相) here is just a name given in contrast to "falsehood" (虛); originally it has no name at all. This is a quiet but decisive move: the text is not asking you to worship a new sacred name. It is pointing through the names to what has no names.
The classical text then gives a string of equivalent terms for this same 法身: 清淨法身毗盧遮那佛 (Pure Dharma-body Vairocana-Buddha), 虗空法身佛 (Empty-space Dharma-body Buddha), 大圓鏡智 (Great Mirror Wisdom), 第八識 (Eighth Consciousness — note: the text uses this term, not 阿賴耶識), 性宗 (Nature-school), 空宗 (Emptiness-school), 第一義空 (First-meaning emptiness), 玄旨 (Mysterious import). These are not dictionary synonyms; they are different doors into the same thing. Some emphasize the body-nature, some the mirror-wisdom, some the consciousness-substratum, some the doctrinal school, some the unspoken point.
Finally, the practical tone. 「但知無心，忽悟即得」 — "just know no-mind, sudden awakening is at once attained." And the warning that immediately follows: 「若著意擬學、存取捨心，反而轉遠」 — "if you deliberately try to learn it, picking and choosing, you actually go further away." The practice does not consist in acquiring a technique called "no-mind"; it consists in not doing the picking-and-choosing activity. The verb 「著意擬學」 (deliberately attempting to study/learn it) is itself the obstacle.
So: 如如佛 is what manifests when the picking-and-choosing — whether toward sage or away from ordinary, whether toward awakening or away from delusion — exhausts itself. The classical text uses 「默契」 (mòqì, "silent correspondence" or "tacit agreement") for how this is "known" — not as a concept, not as a doctrine, but as a recognition that does not need words.
二、生活里的走查 — Walking Through It in Everyday Life
Let me walk each layer of the classical definition through situations you might actually recognize. I'll deliberately flag the spots where modern readers commonly mis-map the concept.
Layer 1: 離盡妄緣 (delusive conditions exhausted) — on a normal morning
You open your phone before brushing your teeth. An app presents a feed. Within seconds, your mind has begun 緣 — weaving: "this article is interesting; that person is doing better than me; my ex looks happy; I should reply; I shouldn't reply; I should be doing something more productive." The mind has started producing the conditions by which it then judges itself.
This isn't the problem. The problem is the part where the mind says "and this is how things really are" — where it stops noticing that the comparison, the reaction, the small internal commentary are activities it is doing, not facts of the world. 妄緣 is the engagement that mistakes itself for the thing itself.
In this moment, 「離盡妄緣」 does not mean "throw your phone in the river." It means: the activity of taking the feed as solid reality loses its grip. You might still pick up the phone. The 妄緣 — the deluded conditions of self-comparison, of grasping at what's shown, of being pushed by small preferences — these can be allowed to come to completion and exhaust themselves. 「盡」 (exhaust) is not "kill" — it is "finish." Many modern readers map 「離」 as "suppress" or "transcend." The classical text is much gentler than that. It speaks of letting something come to completion, like a wave finishing itself rather than being hammered flat.
Where modern people commonly mis-map: we tend to think "離妄緣" means "achieve a mind without thoughts" or "transcend the digital age by going off-grid." The text is not asking for a thought-free state or a life without engagement. It is asking for the wearing-out of the particular activity of mind that mistakes its own conclusions for reality.
Layer 2: 聖凡情盡 (sentiments of sage and ordinary exhausted) — at work
You get a promotion. Your title changes. You start moving in a new circle. Without anyone saying it, a quiet shift happens inside: you begin to identify with "senior," "successful," "the one who knows." On another day, you make a mistake. A quiet shift in the other direction: you identify with "behind," "exposed," "the one who doesn't belong."
The classical text says: 「不用愛聖，聖是空名；不用厭凡，凡是妄立」. The label "senior person" is a name, not a reality; the label "ordinary person" is a delusively established category. When the mind stops being run by either of these preferences — when the sentiment that says "I am now sacred" and the sentiment that says "I am now profane" both come to rest — something is exposed that isn't named by either. 「體露真常」 — the body reveals the truly constant.
Important: this is not "stop caring about work." It is the recognition that the entire preference structure — wanting to be the sage, wanting to escape being ordinary — is itself the activity that obscures the constant. The constant is not something that becomes available when you are sufficiently successful or sufficiently detached; it is what remains when the up-and-down preference structure no longer runs.
Where modern people commonly mis-map: we tend to translate 「聖凡情盡」 into a moral instruction — "be humble, don't have ego, don't be proud." That's a moralization of the text. The text is not making a moral claim; it is naming a structural feature of how minds work. Pride is the surface; the deeper issue is the running program that sorts experience into higher/lower categories at all.
Layer 3: 迷悟一漢 (deluded and awakened are the same person) — in spiritual practice
You have been meditating for two years. You have a teacher. You have had experiences — flashes of calm, moments where the self seemed to drop away. A quiet narrative is building: "I am progressing." There is also a counter-narrative: "I am not progressing enough."
The classical line 「迷也祇是者漢，悟也祇是者漢，不可別有」 cuts directly across this. "The deluded one is this very fellow. The awakened one is this very fellow. There cannot be another." The awakened person who has had the experience is not a different entity from the person who was confused before the experience. The person is continuous.
「向前迷底便是即今悟底」 — the basis on which you were deluded before is the basis on which you are awakened now. This means: the same mind that was confused is the mind that recognizes its own confusion. The recognition is not a foreign light coming in from outside; it is the very activity of the mind that was confused becoming clear about itself.
Where modern people commonly mis-map: we tend to read 悟 as a peak experience, an altered state, a moment of bliss, or a level on a chart. The classical text is not denying that such experiences happen; it is denying that they constitute the structure of awakening. Awakening is structural, not experiential in that thin sense. The text even refuses the framing 「明來暗謝」 (brightness comes, darkness departs) — i.e., awakening as the victory of light over darkness — because that would imply a darkness that can be eliminated, an awakening that is opposed to non-awakening. The text replaces that picture with: awakening is the exhaustion of the picking-and-choosing activity itself.
Layer 4: 心佛不異 (mind and Buddha are not different) — in relationships
You are in a difficult relationship. You find yourself thinking: "If only this person understood me"; "If only I could be the version of me they seem to want"; "If only I could transcend this need for them." Three different movements of mind, all running on the same current — the assumption that there is a "real me" over here and a "real Buddha" over there, and the work is to align them.
「汝心是佛，佛即是心；心佛不異」 says: the mind that is in this very difficulty is not different from the Buddha. Not "contains" — 「不異」, not different. This is not a sentimental reassurance; it is a structural claim. The mind that is exhausted, frustrated, confused in the relationship is the mind that, when its picking-and-choosing stops, is the Buddha. There isn't a Buddha on the other side of the difficulty waiting to be reached.
「若離於心，別更無佛」 — if you set them apart, there is no Buddha to be found anywhere. People sometimes read this as "Buddha is just mind, all external religion is false." That's a much smaller reading than what the text is doing. The text is saying: if you posit a Buddha that exists apart from this very mind that is presently in difficulty, then you've created a phantom to chase. There is no chase. There is the ending of the chase.
Layer 5: 法身不明不暗 (Dharma-body neither bright nor dark) — in the face of "big" and "small" experiences
A piece of good news. A piece of bad news. A spiritual experience. A mundane task. The classical text's 「不明不暗」 says: the reality-body that 如如佛 points to is "neither bright nor dark." This is not a mystical claim about photons; it is a structural observation. The "bright" experiences (meditative absorption, insight, peak moments) and the "dark" experiences (depression, confusion, exhaustion) are both phenomena arising within the field. To identify the Dharma-body with either is to mistake the field for one of its contents.
Modern people commonly mis-map this by saying "everything is Buddha" as a kind of universal affirmation. That's not what the text means. 「不明不暗」 is much sterner than that. It means: the constant that 如如佛 points to cannot be pinned down to your best moments, nor can it be located in your worst moments. It is what those moments arise within — and is therefore not exhausted by the brightest of them.
三、当代人为什么需要它 — Why Contemporary People Need This
Three features of contemporary life make this teaching particularly pointed.
1. The exhaustion of "becoming"
Modern culture runs on a relentless program of self-improvement: optimize, level up, fix, heal, awaken, monetize. Almost every cultural message carries the implicit frame: "you are not yet the real you; here is the next step." Even spiritual and therapeutic cultures are not exempt — they have their own ladders, progress charts, certificates.
The classical teaching 「不改舊時人，祇改舊時行履處」 directly addresses this. The person is not exchanged for a better one. The way of going-about is what changes. This is a relief: it removes the underlying anxiety that "I, as I currently am, am not acceptable, and need to be replaced." It does not say "don't grow." It says the structure of growth is not "old me → new me"; it is "same me, different manner of conduct."
2. The dualistic sorting of self-states
Modern self-tracking — mood apps, identity work, internal family systems, MBTI, enneagram — tends to operate by sorting: "this is the wounded part," "this is the higher self," "this is the inner child," "this is the sage." Each system has its own internal hierarchy of "real you" vs. "false you," "sacred" vs. "profane."
「不用愛聖，聖是空名；不用厭凡，凡是妄立」 is structurally aimed at every such system. Not to invalidate them (they may have useful functions), but to point out: the running program of sorting itself is part of what the text is asking to come to rest. 「聖凡情盡」 is the exhaustion of the preference-sentiment itself, not the choice of a more refined preference.
3. The chasm between mind and meaning
Many contemporary people feel a quiet chasm: their mind is one thing, the meaning or "real life" they are looking for is another. They read books; they do therapy; they go on retreats; they come back; the chasm is still there. The retreat high fades. The book insights don't carry. The therapeutic reframings stop reframing.
「心佛不異」 and 「若離於心，別更無佛」 cut into this. The chasm is not a feature of reality; it is the structure of the search itself. The search is what creates the gap. 「離盡妄緣」 — letting the delusive conditions come to completion — includes letting the search itself come to completion. Not by forcing it, not by giving up, but by the search exhausting itself. 「但知無心，忽悟即得」 — just know no-mind, sudden awakening is at once attained. The 「忽」 here is not "in a flash, with effort"; it is closer to "as soon as the conditions are no longer operative, all at once."
四、常见误读与澄清 — Common Misreadings and Clarifications
Misreading 1: "如如佛 is a separate, transcendent Buddha I need to attain"
This is the most common reading, and it is exactly what the text denies. The text repeatedly insists that this Buddha is not obtained by external seeking: 「若離於心，別更無佛」, 「但離妄緣，即如如佛」. It is not attained; it is exposed when the conditions that obscure it are no longer operative. The classical text never depicts it as something "out there." It describes it as 「心佛」 (mind-Buddha), 「一心法體」 (one-mind Dharma-body), 「諸佛理」 (principle of all Buddhas, pervading empty space and dharma-realm). The teaching dismantles the very project of seeking a Buddha external to one's own knowing activity.
Misreading 2: "悟 is a special peak experience"
Reading 悟 as a flash, a peak, a special state is a common modern mistake. The classical text works against this very directly: 「迷也祇是者漢，悟也祇是者漢，不可別有」 — the awakened person is not a different entity. Furthermore, the text refuses the framing 「明來暗謝」 (brightness comes, darkness departs), i.e., awakening as the victory of light over darkness, because that would imply a darkness that could be eliminated. The text instead says awakening is the exhaustion of the picking-and-choosing itself. Both verbs the text uses — 離 (let go) and 盡 (exhaust, finish) — are verbs of completion and release, not verbs of achievement or accumulation.
Misreading 3: "離盡妄緣 means suppress or transcend emotions"
A common spiritual reading maps 妄緣 onto emotions or feelings and recommends "going beyond emotions." This is not what the text does. 妄緣 is the active engagement of mind that fabricates delusive conditions — the picking-and-choosing activity (the 「存取捨心」 the text warns against), not raw experience. The text never asks you to stop feeling; it asks you to stop the running preference structure that turns feeling into grasping and aversion. The classic Chan warning 「若著意擬學，存取捨心，反而轉遠」 — if you deliberately try to learn this with picking-and-choosing mind, you go further away — is precisely about the trap of making "no preferences" into a new preference.
Misreading 4: "法身 is something achieved after death"
Modern readers sometimes place the Dharma-body in some posthumous or transcendent realm. The classical text describes the three bodies as one body: 「三身一體，一體三身」. The first body, 法身實相佛, is 「不明不暗」 — neither bright nor dark — and 「本來並無一切名目」 — originally without any names at all. This is not an afterlife location. It is the structural feature of reality that is present (or rather, not absent) at every moment, before the sorting of bright and dark, sacred and ordinary, has anything to attach to. It cannot be relocated to some future state without already violating its own definition.
Misreading 5: "心佛不異 is just a nice platitude about 'we are all Buddha'"
The 「心佛不異」 line is structurally very tight. 「汝心是佛，佛即是心」 — your mind is Buddha, Buddha is mind — is not sentimental universalism; it is the elimination of the gap between the seeker and the sought. 「不異」 is "not different," not "similar to," not "contains." The text goes further: 「若離於心，別更無佛」 — apart from this mind, there is no Buddha to find. The sentence refuses the implication that somewhere, in some realm or state, there is a Buddha to be attained. There is only this mind. As a doctrinal note, the well-known line from the 《金剛經》 (Diamond Sutra) — 「若見諸相非相，即見如來」 ("If one sees that all appearances are not appearances, one sees the Thus-Come One") — points in a related direction: the 如來 / Buddha is recognized not by the presence of any specific feature but by the seeing-through of features as features. This resonates with the 古尊宿語錄's 「不明不暗」 and 「本來並無一切名目」.
Misreading 6: "如如 means static or inert"
如如 (rúrú) is a doubled 如. In classical Chinese usage, the doubling indicates "as-it-is, just so" — it points to a non-deviating quality, not an inert one. The text's phrase 「體露真常」 — body reveals the truly constant — uses 真常 (truly constant), not 死寂 (dead stillness). The constant is not stillness in the sense of no-movement; it is constancy through all movements. The 法身 is 「不明不暗」 — neither bright nor dark — which is an active refusal of all defining pairs, not a passive blankness.
Misreading 7: "離盡妄緣 happens once and is done"
Reading 「離盡妄緣」 as a one-time event misreads the text. The text uses both 「離」 and 「盡」 in its core phrasing, and presents this not as a single dramatic moment but as a wearing-out that can be ongoing. 「聖凡情盡」, the repeated use of 盡, all suggest a process that may need to be repeatedly allowed to come to completion in each new situation. The text is not promising one final epiphany; it is naming what is exposed when the conditions of confusion are no longer operative — here, now, and again.
简要回顾
如如佛 is not a Buddha to seek but a Buddha already here, exposed when the conditions of delusion — the picking-and-choosing, the sorting of sage and ordinary, the assumption that mind and Buddha are two — are no longer operative.
The text refuses to substitute a new person for the old one, refuses to substitute peak experience for ordinary conduct, refuses to substitute a higher preference for a lower one. The constant is what remains when the preference-structure that obscures it comes to completion.
「但知無心，忽悟即得」 — "just know no-mind, sudden awakening is at once attained." The 「忽」 here is the precision: not "by effort in a flash," but "as soon as the conditions are no longer operative."
The classical text's word for how this is known is 「默契」 (silent correspondence) — not as a doctrine, not as an experience, not as a belief, but as a recognition that does not need words, in the very person who has always been here.
