I. What This Concept Is About
1. First, the Pair: 所相 (lakṣya) and 能相 (lakṣaṇa)
The *Mahāyānasūtrālaṅkāra* (attributed to Vasubandhu; hereafter *Sūtrālaṅkāra*) opens by setting out a pair of categories: 所相 (lakṣya) — the object being described and identified; and 能相 (lakṣaṇa) — the manner of describing and identifying it itself. The treatise says that the buddhas, in order to gather and benefit sentient beings, reveal the distinction between the two. The 能相 is further divided into three: 分別相 (vikalpa-lakṣaṇa, the discriminative characteristic), 依他相 (paratantra-lakṣaṇa, the other-dependent characteristic), and 真實相 (pariniṣpanna-lakṣaṇa, the perfected characteristic). The three stand side by side, jointly constituting different superimpositions upon the 所相.
This distinction may strike the contemporary reader as redundant. We are long used to collapsing "the world itself" together with "our descriptions of the world" — in the sentence "the weather is nice today," "weather" is real and "nice" is a feeling; who can tell them apart, and who needs to? But what the *Sūtrālaṅkāra* wants to tell us is precisely that this "collapsing together" itself is the entry point of the problem. Every "appearance" (相) seen by sentient beings is not an object lying bare before us, but an appearance "superimposed" (施設) by some mode of cognition; different modes of superimposition yield different appearances. 分別相 (vikalpa-lakṣaṇa) is the most basic — the mode of superimposition closest to everyday mental activity.
So please hold this in mind from the start: 分別相 is not a thing; it is the very mode by which appearances are superimposed. "Appearance" (相) is the shape that grows forth; "discrimination" (分別) is the cognitive act that grows it. Together they mean "the appearance that comes from discrimination." What follows will unpack this "coming from discrimination" in three layers.
2. The Substance of 分別相: 意言 (manojalpa), 習光, and 名義互光起
The *Sūtrālaṅkāra*'s core definition comes in a verse — 「意言與習光，名義互光起，非真分別故，是名分別相」 ("Mental verbalization and seed-illumination; name and meaning illuminating each other — because it is not true discrimination, this is called the discriminative characteristic") — which can be taken apart line by line.
「意言」 (manojalpa): conceptual grasping that can be spoken. The treatise explains that 意言 is 義想 (artha-saṃjñā, "object-recognition"). This term should not be split apart and understood separately — it is a compound: 義 is the object taken up (the thing you are grasping), and 想 is a mental factor (心數, caitta — the kind of psychological accompaniment to the mind-king [心王, citta] that is elsewhere usually rendered 心所; this treatise uses the term 心數). Together, 義想 is "the recognition mental factor carrying its object." When you see a cup of water, "water" is the 義, and "this is water" is the 想; this recognition in turn surfaces as a verbalizable 意言 — "ah, this is a cup of water." So 意言 is recognition that has conceptual content and can be verbalized by the self.
「習光」: the not-yet-formed shimmer of meaning. "習" means seed (種子, bīja) — this treatise does not use the word "seed" but uses "習" instead; same meaning, different wording. And what is this seed? None other than the seed of 意言 — that is, every 意言 that has ever surfaced sinks down and becomes 習. What then is "光"? It is not visual light, not physical photons, but the illuminating function (照了作用) that arises from the seed-habit — an inner illumination that "knows what this is" without yet reaching the linguistic level. Think of it as the "half-second" before a thought surfaces: you have not yet said "what is this," but you have already "recognized" it. This is 習光 (bīja-āloka, "seed-illumination"): with the seed of 意言 as its cause, the directly arising, non-verbalizable but genuinely operative light of meaning.
「名義互光起」: name and meaning mutually triggering. This one is close to daily life. When you hear the word "overtime," a whole set of images surfaces at once — office lights, unfinished spreadsheets, weary shoulders — this is "meaning-light arising in dependence on name." Conversely, when you are actually sitting at your desk, shoulders already aching, eyes fixed on unfinished numbers on the screen, this situation makes the word "overtime" ring out in your mind — this is "name-light arising in dependence on meaning." Name (名, nāma) and meaning (義, artha) illuminate and pull at each other; this is "名義互光起."
The verse's final line, 「非真分別故，是名分別相」 ("because it is not true discrimination, this is called the discriminative characteristic"), is the verdict: the above three — whether the already-arisen 意言, the not-yet-arisen 習光, or the mutual illumination of name and meaning — none of these is a true superimposition; they are all appearances constituted by discrimination. Hence the collective name "discriminative characteristic."
3. Three Kinds of 分別相: Discrimination Grows from Deeper Levels
The previous section discussed the three "substances" of 分別相, but the *Sūtrālaṅkāra* goes further, dividing 分別相 into three kinds and pointing out, for each, what it depends on. These three must be made clear, because they are not progressive levels of depth but three presentations of one and the same discriminative mechanism.
The first: 有覺分別相 (discriminative appearance with awareness) — with 意言 as its substance. This is the most familiar layer in daily life. When you can clearly "know what you are thinking," and can even put that knowing into words, that is 有覺分別. The treatise says: "由此想於所取之義能如是如是起意言之解" — "through this recognition, one can, with respect to the object taken up, thus-and-thus give rise to an understanding in mental verbalization." This "thus-and-thus giving rise to verbalized understanding" is precisely the mark of 有覺: toward the object before you, you can frame it, thus and thus, with one concrete verbalized understanding after another.
The second: 無覺分別相 (discriminative appearance without awareness) — with 習光 as its substance. This is a layer many people overlook, yet it is extremely important. It is not "no cognition" but "no awareness" — no recognition clear enough to be expressed in language. Imagine passing on the street someone who once wronged you: before you have recognized who he is, before you have placed any concept onto him in words, you have already unconsciously stepped half a pace aside. There is "something" in your mind, but that "something" has not yet been named, has not yet become 意言. The treatise says: "尚未能如是如是起意言之解，故為無覺之分別" — "not yet able to thus-and-thus give rise to verbalized understanding, hence it is discrimination without awareness." This is precisely 習光 at work: a seed is touched, it illuminates once, producing a "light of meaning," but it has not yet condensed into a verbalizable concept.
The third: 相因分別相 (discriminative appearance with reciprocal causation) — with 名義互光起 as its substance. This is the wider net. The treatise says that whether in name or in meaning, all distinctions are superimposed through this reciprocal causation — that is, the entire world of verbal conventions (名) and their referents (義) arise in mutual triggering and mutual generation. This characteristic is not merely a matter of the individual mind; it is the entire web woven by language, concept, and culture: when you say "success," when you say "failure," when you say "self" — once these "names" enter the mind, they immediately pull along a whole set of "meaning-images"; and those images in turn solidify the felt reality of the "name." You do not first define "success" and then pursue it; rather, the name "success" and the meaning-light of aspiration in your mind have always grown together and propped each other up.
All three are "non-true discrimination" (非真分別) — this point is crucial. The treatise does not say that 無覺 is deeper than 有覺, or that 相因 is more ultimate than 無覺; it simply says: all three are not true superimpositions; all are appearances constituted by discrimination. The "discrimination" in "discriminative characteristic" is neither pejorative nor commendatory — it is neutral, descriptive, a faithful designation of this entire cognitive mechanism.
4. Ten Kinds of Superimposed Distinctions: How Discrimination Operates on Name and Meaning
The *Sūtrālaṅkāra* further reveals the concrete superimpositions: 「無體、體、增、減，一、異、自、別相，如名、如義者，分別有十種」 ("no-substance, substance, augmentation, diminution, one, many, self, other, as-name, as-meaning — discrimination has ten kinds"). That is, 分別相, on the two levels of "name" (名) and "meaning" (義), superimposes ten kinds of distinctions — 無體 (superimposing as lacking self-nature) and 體 (superimposing as having self-nature); 增 (augmenting what it has) and 減 (diminishing what it lacks); 一 (superimposing as one) and 異 (superimposing as many); 自 (superimposing as self) and 別 (superimposing as other) — and so forth. The treatise does not develop all ten one by one, but this thread is enough to show us: 分別相 is not a single activity; it operates in multiple ways on the two spheres of name and meaning, and to counter it one must illuminate each one in turn.
5. 分別相 and the Four Noble Truths: Why It Leads Directly to Impermanence and No-Self
The *Sūtrālaṅkāra* not only places 分別相 within the system of 能相; it also connects it back to the heart of the entire path of liberation — the four noble truths (四諦, catvāri āryasatyāni). In this synthesis, 分別相 is responsible for explaining "impermanence" (無常, anitya) and "no-self" (無我, anātman):
- With "no-meaning" (無義) as the meaning of impermanence: 分別相 is "ultimately and constantly absent" (畢竟常無) — it has never had a permanent, unchanging self-nature to be had; it arises and ceases moment by moment. Hence it is itself a demonstration of impermanence. - With "discrimination" (分別義) as the meaning of no-self: 分別相 is "only discrimination, no real substance" (唯有分別、無實體) — within it one cannot find a permanent, sovereign "self" driving it. Hence it itself demonstrates no-self.
As for suffering (苦, duḥkha), it is connected to 依他相 ("not-true discrimination of meanings," 不真分別義), because the experience of suffering is grounded in the entire structure of existence arising in dependence on conditions; and cessation (滅, nirodha) is connected to 真實相 ("the extinguishing of all discrimination," 息諸分別義) — when discrimination comes to rest, that is cessation. This thread is worth remembering: 分別相 in this treatise is not merely an abstract descriptive concept; it is the entry point of the entire path of liberation — precisely because 分別相 is "non-true," one can see from it impermanence and no-self, and thereby move toward cessation.
6. A Few Terminological Reminders
Reading the Chinese translation of this treatise, a few terms deserve special attention, or one can easily misread:
- 心數: used by this treatise for "mental factors" (caitta), elsewhere usually translated 心所. Same referent, different term. - 義想: a compound referring to the recognition mental factor (想心所, saṃjñā-caitta) together with its taken-up object (義境); not the recognition mental factor alone. - 習: carries the sense of "seed" (種子, bīja), synonymous with the term "seed" used in other Yogācāra texts, though differently worded. - 光: describes the illuminating function that arises from the seed-habit; it is not visual brightness, nor physical light — it is the "light of knowing" at the cognitive level. Reading it as "radiance" or "glow" would be a misreading.
II. A Walk-Through in Everyday Life
The abstract part is done. Now let us take the three substances — 意言, 習光, 名義互光起 — and walk them through a situation familiar to a contemporary person, to see in which second, in which movement, 分別相 is operating.
Scenario: 8:30 a.m., on the commuter subway, scrolling your phone
First layer — 意言 (the conceptual grasp that has surfaced): Your eyes sweep over a post whose title reads: "The post-00s have already started lying flat — are you still on 996?" Your first reaction is a sentence surfacing — maybe "I want to lie flat too," maybe "nonsense," maybe "well, that makes sense." This sentence appears in linguistic form; you can say it, you can argue with it. This is the 意言 of 有覺分別相: the 義 (the object, that post) passes through your recognition mental factor, is identified, named, and organized into an articulable interpretation. 意言 is not "a thought"; it is "recognition that can be verbalized" — the former is too broad, the latter more precise. Intuitions, feelings, impulses before they are named are not yet 意言; once named and framed in language, they have entered 意言.
Second layer — 習光 (the shimmer half a second before): But before 意言 there is a finer layer. In the very instant you read the words "lying flat" — or even earlier, at the moment you had not yet opened the post, only glimpsed the cover image — your heartbeat quickened a little, your stomach tightened a little, or the opposite: a relief of "ah, finally someone said it" had already risen. These micro-physiological and emotional reactions happen before any linguistic naming. Where do they come from? They come from all the past 意言s about "should I work harder," "am I too tired," "do I deserve rest," accumulated into seeds (習); the cover image before you touches the corresponding seed, and the "meaning" in the seed illuminates once (光) — before you have thought, you have already recognized something. This is the 習光 of 無覺分別相: no awareness (no verbalized understanding), but there is discrimination (an "illumination" has indeed occurred, a classification has been made). Many people assume "without awareness" means "nothing at all" — in fact it is the opposite: discrimination is operating at a deeper, faster level, so fast you cannot even notice it yourself.
Third layer — 名義互光起 (the mutual triggering of name and meaning): Step back further: why do you understand the word "lying flat" at a glance, why does the word "996" irritate you at a glance? This is not a matter of personal memory; this is the entire linguistic world weaving you. The name "lying flat" works on you because it already presupposes a whole set of meanings in your mind — competition, failure, the narrowing of upward mobility, the exhaustion of the younger generation, the sense of helplessness about the future. The moment you hear this name, that whole set of meaning-light automatically turns on. Conversely, when you worked overtime until 2 a.m. yesterday and are now squeezed tiredly on the subway this morning, this tired meaning immediately makes the words "lying flat" echo in your mind. Name triggers meaning, meaning triggers name; name and meaning illuminate each other — this is 相因分別相. It is not something belonging to you alone; it is the entire lexical system, social context, and cultural narrative of an era, already woven into the seeds in your mind. The moment you use language, you are inside this web.
Key takeaway from the walk-through: people most easily reduce "discrimination" (分別) to "thoughts" or "opinions." But after walking through these three layers you will see: opinions (意言) are only the waves surfacing on the sea; beneath the waves is the deeper, faster 習光 (recognition without awareness); and the ocean carrying it all is the entire world of mutual name-meaning illumination (相因). All three layers are called 分別相, all are "non-true discrimination" — that is, this entire mechanism is from beginning to end not a tool for seeing things as they truly are, but a weaving process that makes things "appear as some particular way."
III. Why Contemporary People Need It
The *Sūtrālaṅkāra* says "the buddhas, in order to gather and benefit sentient beings, reveal the distinctions among these characteristics" — this concept is not an academic game; it is a tool for countering afflictions (煩惱, kleśa). Contemporary people need it especially, for at least three reasons.
First, most of contemporary suffering is woven by "名義互光起." On social media, names like "successful person," "refined life," "high emotional intelligence," "independent woman" — each carries a whole set of meaning-light. Before you have even decided whether to envy, the web has already laid out the corresponding meanings (anxiety, inferiority, comparison, impulse spending) in front of you. Understanding "相因分別相" at least allows you, at the moment of being triggered, to ask one question: is this feeling given by the thing itself, or by the name? This question will not solve the problem, but it can interrupt the automatic loop.
Second, the deepest tangles of contemporary people mostly occur at the layer of "習光." You cannot say why you have an inexplicable resistance or attraction to a certain person, a certain scene, a certain piece of information, but your bodily reactions have already given you the answer first. Psychology calls it "the unconscious," "implicit memory," "bodily experience"; but the *Sūtrālaṅkāra* places it in the position of "無覺分別相" — it is the deeper operation of discrimination, and therefore the harder place to illuminate. Recognizing this layer at least allows you to have a little more patience with your own "inexplicable reactions," and a little less self-condemnation: not "why am I like this again," but "ah, so a seed of 習光 in me was touched."
Third, the 意言 layer matters because it is the only entry point for conscious self-reflection. 習光 is too fast, the web too vast, but 意言 is slow enough to be caught. When you can recognize that you are surfacing a particular 意言, that you are using language to frame a particular object as a particular way, you have the first foothold for "not following along." This is why the meditation traditions always begin with "observing thoughts" — not to annihilate thoughts, but to recognize: "this is 意言, this is 分別相, this is not the thing itself."
One clarification is needed: contemporary cognitive science (attention research, predictive coding, implicit memory) does offer descriptions that can be set side by side with 意言, 習光, and 名義互光 — for example, the brain's rapid threat detection (amygdala responses preceding cortical responses) has a structural similarity with 習光; semantic networks can be compared with 名義互光起. But this is only structural similarity, not proof — what Buddhism calls "non-true discrimination" implicates deeper metaphysical questions of subjectivity, subject-object, and the obstacle of the knowable (所知障, jñeyāvaraṇa), which contemporary science has not addressed. So we may use these analogies as mirrors for "convenient understanding," but we should not mistake the mirror for the substance.
IV. Common Misreadings and Clarifications
Misreading 1: Taking "discrimination" (分別) to mean "wild thinking," "emotionality," or "subjective bias." This is a literal-level misreading. In everyday usage, "discriminative mind" (分別心) is often used to mean "unable to regard all things equally" or "being petty and calculating," and 分別 is often conflated with "attachment" (執著) and "affliction" (煩惱). But in the technical context of the *Sūtrālaṅkāra*, discrimination is neutral — it is the entire mechanism of "being able to identify objects through language." You see fire and say "this is fire" — that is not affliction; you hear "overtime" and your heart tightens — that is not attachment either. These are all 分別相, the basic operation of cognition. Equating it with "emotionality" narrows it; equating it with "affliction" escalates it; both are wrong.
Misreading 2: Taking "discrimination without awareness" (無覺分別) as "no cognition." "無覺" literally sounds like "no feeling," but the treatise says clearly: "尚未能如是如是起意言之解" — "not yet able to thus-and-thus give rise to verbalized understanding." It is the layer of recognition not yet expressible in language, not the absence of recognition. Reading it as "vegetative state" or "unconsciousness" goes astray. It is in fact the fastest, deepest, hardest-to-detect layer — before you have even noticed it, it is already running.
Misreading 3: Taking the three kinds as a progressive ladder of practice. One might assume: since 有覺, 無覺, and 相因 are successively deeper, then cultivating to "相因" is ultimate; or: cultivating to "無覺" (no-thought, no-concept) is advanced. But the *Sūtrālaṅkāra*'s verdict is: all three are "non-true discrimination." They are not a ladder; they are three facets of the same mechanism. Countering them is not "entering a deeper layer" but recognizing their "non-truth" — this is the crucial turning of the *Sūtrālaṅkāra* toward 真實相, not drilling deeper into "deeper discrimination."
Misreading 4: Taking 分別相 as some real thing to be "destroyed." The *Diamond Sūtra* (《金剛經》) says "應無所住而生其心" ("give rise to the mind without abiding anywhere"); the *Heart Sūtra* (《心經》) says "照見五蘊皆空" ("illuminates and sees that the five aggregates are empty") — these are all penetrations of "conceptualization," "verbalization," "recognition." But be careful: the point is not to eliminate the function of discrimination (no one can eliminate it), but to see its non-reality. Treating it as an enemy to fight — even if you win, it is useless, because what you were fighting was never a thing.
Misreading 5: Taking "相因" (mutual causation) as "conditioned origination" (因緣和合). The word "相因" easily evokes associations with "cause and effect" and "dependent origination," but in the treatise, "相因" means "name and meaning are each other's cause" — the mutual arising between language and meaning, not causal conditioning in the general sense. It is a highly specific technical term; do not let the literal wording slide it elsewhere.
Misreading 6: Thinking that understanding 分別相 means enlightenment. A concept is a map, not the territory. The *Sūtrālaṅkāra* places 分別相 within the system of 能相 precisely to show: it is only one of the 能相; there remain 依他相 and 真實相 awaiting the recognition of the whole system. Knowing that discrimination is discrimination is only the first light of practice, not the last. Ahead lie two more lights: 依他相 (the conditioned structure of existence) and 真實相 (the thusness after discrimination comes to rest). Walk slowly — do not, on the map, think you have already arrived.
One last sentence to remember: **分別相 is not an error, nor a disease — it is the "default mode" by which sentient beings cognize the world. The *Sūtrālaṅkāra* tells us how this default mode operates (意言, 習光, 名義互光起), why it is not real (非真分別), and how it is situated within the path of liberation (leading to impermanence and no-self, moving toward cessation). Understanding this mode does not mean we should stop discriminating — that is impossible; nor does it mean we should despise discrimination — that is unnecessary. It means that at each surfacing of the recognition "what is this," we can recognize one more layer: you are dealing with a woven appearance; this appearance affects you very really, but it is not the thing itself.** Recognizing this layer — you are already standing at the entrance of the path.
