What This Concept Is Saying
The Saying, Taken Whole
The Chan saying stands as one of the most radical in the entire Zen record. From Nanquan Puyuan (南泉普願), it reads:
「三世諸佛不知有，狸奴白牯却知有。」 *"The Buddhas of the three times do not know it; the housecat and the white ox, on the contrary, do."*
Before you read anything else, sit with this sentence. The entire teaching of Buddhism — thousands of sutras, centuries of cultivation, the very goal of awakening — is here declared *inadequate*. And a cat and an ox are declared to possess what the Buddhas lack.
This is not a casual remark. The classical material tells us that Nanquan arrived at it through a serious path: he began with monastic discipline (律), went deep into the *Avataṃsaka Sūtra* (華嚴) and the *Laṅkāvatāra Sūtra* (楞伽), trained in the *Zhong-Bai contemplation methods* (中百門觀 — the Zhonglun/Bailun-based Tiantai insight practices), and only then, hearing Mazu's word "outside words," gained what the commentator Wansong calls "the work of forgetting the fish-trap" (頓獲忘筌之功 — i.e., having caught the fish, you no longer need the basket). So when Nanquan speaks, he is not dismissing Buddhism from the outside. He is speaking from inside the tradition's deepest resources, and turning them against their own conventional logic.
He follows the saying with a gloss that is the operative key:
「今時沙門須向異類中行始得。」 *"Today's śramaṇas must walk among the 'different species' to succeed."*
The saying and this gloss belong together. One announces the reversal; the other tells you what to do with it.
Breaking Down the Components
Each term in the saying is doing precise work. They cannot be paraphrased away.
三世諸佛 (Sānshì Zhūfó — Buddhas of the three times): All awakened beings, past, present, and future. The highest category Buddhism knows — those who have fully realized the dharma, crossed over suffering, and possess the ten powers, the four fearlessnesses, the thirty-two marks. If anything in the Buddhist universe "knows" the dharma, they must.
不知有 (Bùzhī yǒu — do not know "it/have"): Here *yǒu* (有) is a Chan technical term pointing to Buddha-nature, true suchness, the original ground. *Zhī* (知) is "to know" — but in this context, knowing is already a verb that implies a knower and a known. To "know" the dharma is to stand over against it as object. The Buddhas, even at their full awakening, cannot *know* this ground as an object, because it is not an object. They live it; they do not know it. This is the first cut.
狸奴 (Línú — housecat): A domestic cat, kept in the kitchen (lí 狸 = wildcat; nú 奴 = slave/servant — a small domestic creature, the most ordinary animal in a Chinese monastery of the Tang era). Cats were also associated in Tang culture with slyness, with the uncanny, with the nocturnal. In Nanquan's monastery there was an actual cat, and it was the occasion of one of the most famous koans — the *killing-the-cat* case (斬貓案) we will come to.
白牯 (Báigǔ — white ox/bullock): A white working ox, an animal of agriculture, not a sacred bull. White because it has no special coloring, no mark, no symbolic status — just an ordinary working beast of the fields. It pulls the plow; it chews its cud; it stands in the rain.
却知有 (Què zhī yǒu — on the contrary, do know "it/have"): *Què* (却) is the particle of reversal — "and yet," "on the other hand," "precisely." The cats and oxen, precisely because they have not constructed the apparatus of a knowing subject standing over against an object, *do* know the ground. They know it the way they know their own lives — not as a thesis, not as an attainment, but as the unmediated texture of being alive.
The Water-Buffalo Layer: Embodiment in the Ordinary
Wansong's commentary does not leave the saying as a paradox. It unfolds the same insight through the companion image of the water buffalo (水牯牛), and this second layer is essential — without it, the saying reads as mere provocation.
Nanquan says of himself:
「王老師自小養一頭水牯牛，擬向溪東牧，不免食他國家水草。溪西牧亦不免食他國家水草。如今不免隨分納些子，總不見得。」 *"Old Master Wang has raised a water buffalo since childhood. If I graze it east of the stream, it inevitably eats the country's grass and water. If I graze it west, the same. So now I just accept whatever portion comes, and on the whole you cannot find him."*
This is not a fable. It is a working image for the awakened life *after* awakening. The water buffalo is the awakened person moving through the ordinary world. East or west, every direction involves eating the country's grass — i.e., receiving sustenance, participating in conditions, being implicated in the world. The awakened one does not escape this; he does not transcend it by some elevated path. He *grazes* — he accepts what comes, eats what is given, lives where he is.
Nanquan reinforces this in a later exchange with his disciple Zhaozhou (趙州從諗):
「知有底人向甚麼處去？」「向山前檀越家作一頭水牯牛去。」
*Where does a person who knows go?* — *He goes to be a water buffalo in the house of a lay patron, just in front of the mountain.*
On his deathbed Nanquan adds:
「汝若隨我，須銜取一莖草來。」 *"If you want to follow me, you must fetch a stalk of grass in your mouth."*
You want to follow the awakened one? Don't climb a mountain; don't sit in meditation; carry a stalk of grass — do the most ordinary work that an animal does. The destination of the awakened life is not above the world. It is *as* a working animal, with a mouth full of grass.
Wansong sums up the connection explicitly: the awakened person lives in the world "like a buffalo being herded, just accepting one's portion" (隨分受用). The "ultimate destination" (究竟歸處) is not elsewhere — it is *still in the herd*. Wansong will later say of Nanquan: *"Nanquan is still in the water-buffalo herd, shaking his head and wagging his tail, unseen"* (南泉依舊水牯牛隊裡搖頭擺尾不見).
The Cat-Killing Layer: When Words Fail, Only This Remains
The "cat-and-white-ox" concept does not stop at words. It shows itself as action in the most famous of Nanquan's recorded deeds, the cutting-the-cat koan (斬貓公案).
Two halls of the monastery were quarreling over a cat. Nanquan held up the cat and said: "Say the right word and I will not cut it" (道得即不斬). No one could answer. He cut the cat in two. Later he held up the same question to Zhaozhou, who took off his sandals, put them on his head, and walked out.
Wansong's comment is the load-bearing one: *"Because of the cat there was dispute; Nanquan did not mediate, did not punish. A genuine person deals with people through the fundamental matter."* (因貓致諍，南泉也不與解勸，亦不與懲罰。本色道人以本分事為人。)
Later in the tradition, a Liao-dynasty master wrote the *Jingxin lu* (鏡心錄) condemning Nanquan for killing a living creature; the meditation master Wen responded with the *Wujin deng bianwu* (無盡燈辨誤) defending him, noting that the older recension says Nanquan "made a gesture as if to chop in empty air." Whether the cat was literally killed or only mimetically threatened, the point is the same: when no one can meet the moment with the real thing, Nanquan does not hesitate to enact the matter. He does not preserve the surface — the cat, monastic harmony, the appearance of compassion — at the expense of the substance.
Wansong himself ties the two cases together: Nanquan "remains in the water-buffalo herd, shaking his head and wagging his tail, unseen." The cat and the buffalo are not different topics. They are two faces of the same teaching: in a world where every conceptual resolution is a dodge, the only response that does not betray the matter is the response that comes *as* the matter itself — the animal gesture, the unmediated act.
The Commentators' Layer: How the Tradition Has Held This
Wansong's commentary preserves the full range of the tradition's reception rather than settling on one side.
- Feishan Facheng Jiezhu (飛山法師戒珠) wrote the *Bie Chuan Xin Fa Yi* (別傳心法議 — "A Discussion of the Separately Transmitted Mind Dharma"), harshly criticizing Nanquan as *"not fond of learning, not knowing the source"* (不嗜學不知本). - The Wujin Deng Fu Ji (無盡燈附集) countered by defending Nanquan on the basis of his lineage and realization. - Changsha Jingcen (長沙景岑) answered the same saying this way: *"Why don't the Buddhas of three times know it?"* — *"Before they entered the Deer Park, they were a little better off."* *"Then why do the housecat and white ox know it?"* — *"How can you begrudge them?"* (「未入鹿苑時猶較些子。」「汝爭怪得伊。」) - Wansong himself, with characteristic honesty, says he can only "stand by and watch" (只可傍觀), and notes that not only Yunyan and Daowu but even Cuiyan must "re-penetrate" (重參) the matter of *"Do you know it or not?"* (知有也未).
The point of preserving these positions is not to be agnostic. It is to show that even among the most realized masters of the tradition, this saying does not produce easy consensus. It is a *living* matter, not a settled doctrine.
Walking It Through in Contemporary Life
The saying is old, but it can be walked through ordinary scenes. Let's take a few.
The exhausted therapist and the laughing child
Imagine a senior psychotherapist — well trained, deeply read, having processed their own share of material — sitting with a client. The client talks. The therapist listens, classifies, locates the pattern, knows what to say. And then their own child runs in from the garden, muddy, laughing, with no idea that they are doing anything important. The child is fully *there*. The therapist is *applying*. The child, in Nanquan's terms, *knows*. The therapist, despite all their knowledge, does not.
This is not a romanticization. It is a precise observation: the child's presence has no separation between experience and the one having it. The therapist's expertise has built a whole apparatus of "knowing-about" that itself can become the obstacle to *knowing*. Nanquan is not saying throw away your training. He is saying: when the apparatus of knowing has done its work, see whether there is something prior that the apparatus itself cannot touch.
The startup founder and the bakery cat
A founder of a successful tech company spends their days in dashboards, OKRs, optimization loops, growth metrics. Every interaction is processed through "what is this for." Then on a Sunday morning they sit in a café, and a cat walks in, rubs against a customer's leg, eats a piece of dropped croissant, sleeps in a sunbeam. The cat has no strategy. The cat does not "know" anything in the founder's sense. And yet the founder feels something in watching the cat — a kind of rightness, a reminder.
This is what *却知有* points to. The cat is not enlightened. The cat is not aware that it has Buddha-nature. But the cat also has no bifurcation between itself and what is happening. The founder, with all their sophistication, has lost something the cat has not lost — not because the cat is superior, but because the cat has never built the dualism that the founder has built, and now cannot fully dismantle.
The meditation retreat and the dog at the door
You go on a long retreat. You sit. You read the suttas. You get concentrated, then distracted, then concentrated again. You have insights. You watch the insights become subtle attainments. You begin to see how the very act of "watching" is itself a fabrication. You come home exhausted, with something real and something phantasmal in your hands.
Your dog greets you at the door. Tail wagging. Utterly uninterested in whether you had stream-entry or just got bored. The dog knows you are back. That is the whole of its knowing.
The teaching is *not* that you should imitate the dog. The teaching is that the dog's knowing — the unmediated, non-strategic, "just this" — is the very thing the retreat was, at its deepest, pointing toward. The retreat was meant to dismantle the apparatus so that this — what was always already here — could show itself. The dog never had to dismantle anything. So the dog has what the Buddhas of three times, in one specific sense, "do not know."
The mistake most people make in mapping this
The most common mis-mapping is to read this as an instruction to *become* like the cat, to *try* to be more "natural," to chase the child's mind or the dog's presence as a goal. That is precisely what Nanquan is *not* saying. The water buffalo does not *try* to be a water buffalo. The cat does not *try* to be a cat. Trying to be like the cat is the most refined form of dualism, the ego in disguise. The teaching is about *seeing through* — seeing that the cat's "knowing" is not an achievement you can replicate, but a reminder of what was never missing.
Why Contemporary People Need This
We live in a civilization that has perfected the apparatus of "knowing-about." We have specialists, frameworks, taxonomies, certifications, evidence-based protocols. And we are, in many ways, more lost than ever — more anxious, more fragmented, more unable to simply *be*. The reason, this Chan saying suggests, is not that we lack intelligence, training, or even sincere practice. It is that the very machinery of sophisticated knowing can become an obstruction to the simpler, prior *being* that it was originally meant to serve.
Three places where this matters particularly:
1. The burnout of self-improvement. The contemporary wellness industry tells us we can optimize, heal, and upgrade ourselves. Nanquan's saying reminds us that there is a knowing that no self-improvement project can produce, because it is not produced *by* anyone. This is not a counsel of passivity. It is a diagnostic: if your self-improvement is increasing the sense of a self that needs improving, the apparatus is now the obstacle.
2. The decoupling of expertise from wisdom. We have more psychological and contemplative expertise than any previous generation. We also seem, in many surveys, to be less at ease. This is not a contradiction — it is exactly what Nanquan's saying predicts. Expertise is *knowing-about*. Wisdom, in this register, is what remains when *knowing-about* has been put down. The cat and the ox live entirely in the latter, and have no access to the former.
3. The difficulty of acting without a script. The cutting-the-cat koan points to this. We live in a world saturated with appropriate responses, de-escalation protocols, communication frameworks. There are moments when none of these meet the matter — when the situation asks for something that has not been scripted, something from below the level of the script. The saying does not tell you what that response should be. It tells you that when the conceptual apparatus fails, *the matter itself* will move you — if you have not built too much between yourself and it.
Common Misreadings and Clarifications
"Nanquan is saying animals are more enlightened than humans."
No. He is not ranking species. The cats and oxen are not enlightened; they have not realized anything. They have simply not constructed the framework of "knowing subject vs. known object" that even an awakened Buddha has to navigate. The saying is structural, not zoological. If you transmigrate as a cat with full human conceptual machinery, you are back in the apparatus. The point is the absence of a specific kind of split, not the presence of fluff and whiskers.
"Nanquan is rejecting Buddhist study and practice."
Also no. The classical material makes this explicit: he trained deeply in vinaya, *Huayan*, *Laṅkāvatāra*, and Tiantai contemplation before arriving at the saying. He is not a primitivist. He is a sophisticated practitioner pointing to what he discovered is *beyond* sophistication. Wansong notes the seriousness of his training, and even the harshest critic (Feishan) attacks him for *failing* to meet the standards of learning, not for *ignoring* them.
"The cats and oxen know something the Buddhas don't — so this is a hidden, esoteric teaching the Buddhas never taught."
This is the most seductive misreading. It treats the saying as the disclosure of a secret doctrine. But the saying does not give you any *content* to possess. It gives you no teaching, no thesis, no doctrine. It removes something — the belief that the dharma is something to be known by a knower. There is no esoteric teaching here, only a stripping away. The Buddhas themselves, in other places in the tradition, point to the same stripping. The saying is a high-wire act of language, not a delivery of new content.
"This is nihilism — saying nothing matters, no practice, no ethics."
Look at the water-buffalo layer: the buffalo grazes, accepts its portion, walks the road. This is not nihilism; it is the most embodied, ordinary activity. And the cat-killing case is decisively *not* passive — Nanquan acts, decisively, when the matter requires action. The teaching does not dissolve ethics; it dissolves the *self-image* that has been pretending to be the source of ethics. The awakened buffalo has clearer ethical sensibility than the un-awakened scholar of ethics, because the scholar is still operating inside a framework of self-image that the buffalo is not.
"Nanquan really killed a cat, so this is a celebration of violence."
The tradition itself disputed this. Wansong preserves both versions — the one that takes the killing literally and the one (the older recension he cites) that says Nanquan only made a gesture "as if to chop in empty air." He does not adjudicate. The point of the case is not the harm done to the cat; the point is what Nanquan was pointing at when he asked the question and then acted. Reading the case as a celebration of violence misses the koan entirely — you end up arguing about Tang-era animal welfare when the case is about the limits of conceptual resolution.
"Just be natural — stop trying, drop everything."
This sounds like the right reading but is actually the most dangerous misreading. The tradition is full of warnings against this kind of "naturalness" — because it quickly becomes a new pose, a more refined ego. The cat is not "trying to be natural." The cat has no project. *You* have a project, and that is why the teaching is hard. It is not an instruction to drop your project (that would be yet another project). It is a pointing to what is here *before* projects — and it cannot be reached *as* a project, only recognized when the apparatus of projects is no longer the only thing you are looking through.
A final word. Wansong himself says of this saying: *"I can only stand by and watch"* (只可傍觀). He does not pretend to have the last word. He does not pretend the matter is settled. He points out that even Yunyan, Daowu, and Cuiyan — all great masters — must "re-penetrate" the question *"Do you know it or not?"* This is not modesty. It is honesty about what the saying points to: a matter that does not get *settled*, only *lived*, again and again, in each new moment, by each new buffalo in each new herd.
