The Heart of the Concept
The *Mahāparinirvāṇa Sūtra* (《大般涅槃經》, Southern version), in its discussion of the twelve divisions of scripture (*十二部經*), pauses to make a distinction that sounds like a piece of academic cataloguing but turns out to be one of the most practical things the Buddhist tradition ever said about how truth gets communicated. It names three intentionalities under which the Buddha (*Tathāgata*, 如來) speaks:
- 隨自意說 (*suízìyì shuō*) — speaking in accordance with one's own realized intent; - 隨他意說 (*suītāyì shuō*) — speaking in accordance with the other's intent and capacity; - 隨自他意說 (*suízìtāyì shuō*, sometimes just 隨自他說) — speaking in alignment with both.
These are not three truths. They are three *postures* in which a single truth-bearing teacher addresses a world whose listeners are unevenly ready. To understand 隨自他意說 is to understand the third posture: the moment when the Buddha's speech does not originate purely from his own realization, nor does it bend entirely to the questioner's pre-existing frame — instead, it moves alongside the discernment already present in wise human reflection.
The canonical formula is striking: *"世間智者說有，我亦說有；智者說無，我亦說無"* — "What the wise of the world say exists, I also say exists; what the wise of the world say does not exist, I also say does not exist." This is the definition of 隨自他說 in the sūtra's own words. It is not capitulation to popular opinion, and it is not a mere rhetorical compromise. It is the recognition that some truths are jointly discernible — the kind of thing that any genuinely attentive, unconfused mind can verify on its own — and that the Buddha's teaching is allowed to *travel together with* that shared discernment when delivering them.
The sūtra then gives the working example of how to read this against the five sense-pleasures (*五欲*). On the four markers — permanence (*常*), bliss (*樂*), self (*我*), purity (*淨*) — the text says: when wise people discern that pleasures are impermanent, suffering, without self, and cut-off-able, the Buddha affirms the same; when wise people discern that pleasures are permanent, self-blessed, and pure "there is no such place," the Buddha affirms that too. This shared ground is the territory of 隨自他說.
But to see why 隨自他說 is not the whole picture — and why we need the full three-fold scheme — we have to look at the other two voices first.
The Other Two Voices, So the Third Has Edges
隨自意說 — the Voice of Realization
When Śāriputra (*舍利弗*) and five hundred monks were asked what causes the body, they each named something different: ignorance (*無明*), craving (*愛*), volitional formation (*行*), consciousness (*識*), name-and-form (*名色*), the six sense-bases (*六入*), contact (*觸*), feeling (*受*), and even the five sense-pleasures (*五欲*) as the bodily cause. Each monk said something different. The Buddha validated every single one as a correct teaching. The sūtra's own explanation: *"我為欲界眾生說言父母即是身因，如是等經名隨自意說"* — "I say to beings of the desire-realm that father and mother are the cause of the body; such sūtras are called 隨自意說."
This is the voice in which the Buddha speaks from what he himself has seen. He is not asking the audience's permission. The teaching lands wherever his realization lands, even if the same doctrinal point can be approached from multiple valid angles. The same wisdom, the same eye — and therefore the same authoritative saying.
In the sūtra's most pointed application, the Buddha-nature (*佛性*) teaching is split this way: the statement *"一切眾生悉有佛性"* ("all beings without exception possess Buddha-nature") and *"一切眾生不斷、不滅乃至得阿耨多羅三藐三菩提"* ("all beings are unbroken, unextinguished, and will attain anuttarā-samyak-saṃbodhi") is classified as 隨自意說 — the Tathāgata's own definitive word.
隨他意說 — the Voice Tuned to the Listener
The classic example is the elder Bādīla (*巴吒羅長者*), who came to the Buddha armed with illusion-magic (*幻術*), trying to corner him with the question "do you know illusion?" The Buddha did not meet force with force. He used the analogy of a Caṇḍāla outcaste (*旃陀羅*) in Śrāvastī who survived by holding his breath — gradually leading the elder through stages until he saw his own error. Then the Buddha taught the Four Noble Truths, and the elder attained the fruit of stream-entry (*須陀洹果*). The sūtra labels this whole exchange 隨他意說.
Here, the teaching's shape is dictated by the listener's mind-stream, by where the question is actually stuck. The Buddha does not unload his highest view. He meets the questioner precisely where they are — sometimes at the level of, frankly, polite strategic redirection.
In the Buddha-nature schema, this is the category into which the statement *"十住菩薩少見佛性"* ("bodhisattvas of the tenth ground see Buddha-nature only slightly") falls — because these bodhisattvas, even having mastered the Śūraṅgama samādhi (*首楞嚴三昧*) and three thousand dharma-gates, know their own future awakening but do not yet see every being's certain awakening, so this formulation is taught *for them, in their idiom*.
隨自他意說 — The Third Voice
Now the third posture becomes legible. The sūtra's own test case: *"一切眾生悉有佛性，煩惱覆故不能得見，我說如是，汝說亦爾"* — "All beings possess Buddha-nature, but because it is covered by afflictions they cannot see it; I say so, and what you say is also so."
Notice what is happening. The doctrinal content here is the same as the 隨自意說 statement — all beings have Buddha-nature. But the form is different. The Buddha is no longer making a sovereign declaration. He is acknowledging that the interlocutor, on this specific point, is also seeing correctly. The teaching moves alongside the wise discernment already present on the other side of the conversation.
This is what makes 隨自他意說 its own category rather than a sub-case of 隨自意說. The Buddha's word is not diminished — but it is no longer standing alone. It travels with a co-author in discernment.
Where This Sits in the Larger Picture
The three voices sit inside the sūtra's discussion of the twelve divisions of scripture, and immediately after them the text introduces the Tathāgata's 七種語 — seven kinds of speech: 因語 (cause-language), 果語 (effect-language), 因果語 (cause-and-effect-language), 喻語 (analogy-language), 不應說語 (language of what should not be said), 世流布語 (worldly conventional language), and 如意語 (mind-of-the-Tathāgata language). Together, the three voices and the seven languages form one architecture of skillful means (*方便善巧*) — the recognition that truth does not arrive in the world pre-dressed. Someone has to dress it for each room it enters.
This is what the concept is *really* about: the dharma's wardrobe. Three postures, seven linguistic moves, twelve textual forms — all to honor the fact that awakening is one thing, and the human beings being woken up are many.
Life Walkthrough: Where These Voices Show Up
Let me walk one concept — say, *impermanence* — through several ordinary situations, and watch which of the three voices is doing the work.
1. Commuting, and the friend who just lost her father
Your colleague sits in the back seat of the ride home. She is silent, then suddenly says: "I keep thinking — why him? He was the kindest person. Why would this happen to a kind person?"
What do you say?
Most people intuitively pick 隨他意說 here: they meet the grieving person exactly where she is. "I don't know why. I'm so sorry. He was wonderful." Some will go to 隨自他說: "I think the older I get, the more I notice that good people aren't spared — that kindness and protection aren't the same thing." This travels *with* what any grown human who has lived through enough loss has also noticed.
What you do not say, at least not yet, is the 隨自意說 version: a teaching about how the seeming self that "lost a father" was never a stable self to begin with, how the continuity she is grieving is itself a mental construction that the Buddha's full vision sees through. That teaching is not false. But it would be a violence in that back seat. The Tathāgata's own sūtras don't deliver it there either.
Where people mis-map this: they think being a "deep" Buddhist means always defaulting to 隨自意說 — saying the highest thing. The sūtra's taxonomy suggests the opposite: speaking the highest thing to someone who cannot receive it is itself a kind of unskillfulness.
2. 刷手机 / the algorithm and the comment thread
You scroll past a video. A meditation teacher — credentialed, clear-eyed — says something about consciousness that, frankly, sounds speculative. The comments are split: devoted followers, sharp critics, and a third group saying "well, neuroscience seems to be approaching similar things, so maybe both."
What is happening in that thread is a low-resolution version of the three voices. The teacher is speaking 隨自意說 — from their own realized (or claimed-realized) vision of mind. The devotional followers are receiving in 隨他意說 mode — taking in whatever fits the frame they already have. The "neuroscience is approaching this" crowd is doing a kind of 隨自他說: trying to find the line where their ordinary empirical discernment and the contemplative tradition can walk together, where both say the same thing.
Where people mis-map this: they confuse *alignment with worldly wisdom* (隨自他說) with *submission to worldly opinion*. The sūtra is very specific — the alignment is with 世間智者, with *wise* worldly people, on matters the wise can verifiably discern. It is not with whoever has the loudest microphone. When you say "the science also agrees," you are invoking the third voice. When you say "everyone online agrees," you are not.
3. 加班 / explaining to the new intern why the codebase is the way it is
The senior engineer could say, "the system was designed badly and we've been patching it" — that's the engineer's own honest read, a kind of 隨自意說 voice. They could say, "industry best practice at the time was X, so we did X" — that's 隨自他說, traveling with the wisdom-of-the-trade. They could say, "look, I know you need this done by Friday, and you don't have the whole context, so here's what to focus on" — that's 隨他意說, meeting the listener where they actually are.
A mature senior develops a sixth sense about which register each conversation is calling for. So does a mature teacher.
Where people mis-map this: junior employees often hear 隨自意說 as arrogance ("they're just telling us what they think") when it is actually the speaker offering their earned understanding. Conversely, when a manager says "industry best practice says X" but really means "I personally believe X but want cover," they are abusing the 隨自他說 register — using the world's apparent agreement as camouflage for personal opinion. The Tathāgata, in the sūtra's account, does not do this.
4. 亲密关系 / the partner who is going through a career collapse
She comes home saying, "I think I'm a fraud. Everyone at work is going to figure out I'm incompetent."
The honest move is not to say "you are Buddha-nature, all beings have it, this is just affliction covering your true self" — that would be 隨自意說 deployed badly, and you'd be right to feel it's also a little insulting.
What good friends often do is 隨自他說: "You know, the research on imposter syndrome is actually pretty clear — something like 70% of people feel this at some point, and it correlates almost inversely with actual competence." This travels *with* what good empirical psychology has discerned. It doesn't pretend to be a final answer about her worth, but it puts her experience next to something the wise of the world have also seen.
Then, in a quieter moment, you might offer something more direct from your own seeing — a small 隨自意說 moment. Not a doctrine. A recognition.
5. 育儿 / explaining death to a six-year-old
"She went to sleep and won't wake up" — the parent speaks 隨他意說, in a vocabulary the child can metabolize. "All living things die eventually — people, dogs, trees" — this is 隨自他說, moving alongside what any attentive human eventually notices. "Her body has returned to the elements; what loved her in her is not a thing that can die" — only in the right moment, with the right child, with enough prior context, would 隨自意說 be appropriate.
Notice: all three voices can be true at once about the same event. The death is permanent in one sense, and not-permanent in another, and the child can hold exactly none of that for now.
Why Contemporary People Need This Taxonomy
Three reasons, in increasing weight.
1. We live inside an information environment that has lost register.
The most striking feature of contemporary discourse — online and off — is that speakers and listeners no longer agree on which register is being used. Someone tweets a 隨自意說 (here is my realized view), and it is read as a 隨他意說 (why is this aimed at me personally?), and then it is contested as if it were a factual claim that would need 隨自他說 alignment with worldly evidence. The sūtra's three voices do not compete. They are different moves for different moves. Naming them is the first move toward not arguing past each other.
2. We are surrounded by teachers, both human and artificial, who need to know what kind of voice they are using.
A therapist meeting a client where they are today is doing 隨他意說. A doctor explaining that "the medical consensus on this treatment is X" is doing 隨自他說. A senior practitioner sharing what they have seen with their own mind is doing 隨自意說. When a teacher unconsciously mixes these — most commonly, dressing personal opinion in the language of consensus, or dressing consensus in the language of personal revelation — confusion follows.
A useful contemporary analogy (with the limit clearly marked): modern AI assistants *behave* as if they speak in all three registers. They will match your level (隨他意說), they will report mainstream consensus (隨自他說), and they will sometimes present synthesized patterns as if they were first-person realizations (a kind of imitation 隨自意說). The imitation is not the thing — an AI has no realization — but the structural pattern the system has learned to mimic is exactly the sūtra's pattern. We can borrow the structure as a lens for our own speech, while keeping clear that the lens is being borrowed and not identified with the practice.
A neuroscience caveat worth naming: the contemporary study of "theory of mind," audience design in communication, and code-switching between registers describes something *analogous* — the brain does adjust its linguistic and conceptual output depending on inferred interlocutor. This is empirically real. It does not, however, *explain* the sūtra's claim. The sūtra is not describing a cognitive mechanism. It is describing the conduct of a being whose realization is total, and whose speech is therefore free to match any of three legitimate postures without distortion. Cognitive science describes the apparatus; the sūtra describes the use of the apparatus by an awakened mind. Conflating the two is a common contemporary error.
3. We ourselves need to recognize which voice is being addressed to us.
This may be the deepest contemporary need. When someone teaches you, *which* voice are they using? When a senior in your tradition says "the nature of mind is empty," is that a 隨自意說 — a report from their own seeing — or a 隨自他說 — something wise contemplative people across traditions also recognize? The two demand different responses from you. The first, you can weigh; the second, you can verify against your own experience; the third (隨他意說), you may need to set aside for now until your capacity grows. The sūtra's taxonomy gives you a way of triangulating what is being asked of you when teaching arrives.
Common Misreadings and Clarifications
Misreading 1: "隨自意說 means the Buddha just says what he personally thinks."
This is the subjectivist collapse. It imagines 隨自意說 as opinion — strong opinion, awakened opinion, but still opinion. The sūtra's examples make clear that 隨自意說 is reporting from realization. When five hundred monks each name a different cause of the body and the Buddha validates each, this is not "everyone is entitled to their view." It is "from the standpoint of one who has fully seen, all of these are valid angles into the same actual nature of how bodies arise." The voice is sovereign because what it reports is the case. Take away the realization, and you do not have 隨自意說; you have a person with opinions.
Misreading 2: "隨他意說 means the Buddha compromises the dharma to please people."
This is the capitulation collapse. It imagines 隨他意說 as flattery or strategic evasion — what we might today call "saying what the customer wants to hear." The elder Bādīla case is the antidote. The Buddha did not flatter him. He redirected him, with the precision of a surgeon, into a question he could actually work with. Meeting someone where they are is not the same as telling them what they want to hear. It is telling them what they can metabolize — and only that.
Misreading 3: "隨自他意說 means the Buddha endorses whatever the world thinks."
This is the populism collapse. The sūtra's qualifier is doing all the work: 世間智者 — *the wise of the world*. Not the loud, not the majority, not the trending. The discernment of those who have actually looked. And even then, the alignment is on specific matters the wise can verifiably see — the impermanence of pleasures, the cut-off-ability of craving. On the deepest matters — the full Buddha-nature teaching — the sūtra does not place them in 隨自他說. They remain 隨自意說. The third voice is real, but it has a domain.
Misreading 4: "The three voices mean the Buddha contradicts himself."
This is the inconsistency collapse, and it is probably the most common modern reading. The sūtra, by explicitly naming the three voices, is preventing this reading. The same sentence delivered in two voices is the same sentence with different intentionalities, addressing different capacities, meeting different kinds of assent in the listener. A teacher who never varies their voice has only one student. A teacher who varies it without naming it produces confusion. A teacher who varies it and names it produces the conditions for genuine learning.
Misreading 5: "This is just relativism with a spiritual wrapper."
The opposite is closer to true. Relativism says *all views are equal*. The three-voice schema says all views are not equal, but some truths can be jointly verified — and the Buddha is willing to walk alongside that joint verification when delivering those truths, while reserving his own voice for what only full awakening can report. This is more rigorous than relativism, not less. It requires distinguishing — carefully, repeatedly — between what can be jointly seen and what can only be reported from realization. Relativism refuses to make that distinction. The Tathāgata, in this sūtra, makes it constantly.
Misreading 6: "I should figure out which voice I'm using and stay there."
The mature reading is the opposite: in any genuine teaching situation, you are likely to move among all three. You begin by meeting the listener where they are (隨他意說). You align with what wise reflection also sees (隨自他說). And from your own realization, you offer what only your realization can offer (隨自意說). Holding all three without freezing in any of them is itself a skill — and the sūtra's structure is best read not as three boxes to stay in but as three ranges of motion to be available for.
What the Concept Is Doing in the Larger Path
If we step back, *隨自他意說* — the third voice — is doing something quietly radical in the Buddhist map. It is granting dignity to worldly discernment. It says: on the matters that wise human beings can actually see, the Buddha is not above walking alongside your seeing. He is not above it, because the truth does not require him to be. Where the truth can be jointly discerned, the Buddha's teaching travels *with* the world's wisdom, not over its head.
But — and this is the half most easily missed — it does so *without surrendering* the register where his word stands alone. The Buddha-nature teaching remains 隨自意說: a sovereign declaration that not every wise worldly person can verify on their own. The third voice is permitted precisely because the first voice is held firm. Take away the first voice's firmness, and the third voice collapses into populism. Hold the first voice too rigidly, and the third voice never appears.
The art — for a Tathāgata, and for us — is to hold both.
That is what *suízìtāyì shuō* is for.
