Imagine an old-fashioned steelyard balance: the suspension cord, the beam, the counterweight, the pan. You hang something on it; one end of the beam tilts up, the other sinks down, and you slide the counterweight until the beam hangs level. At that moment, there is necessarily one engraved mark on the beam that aligns with a fixed reference line—that mark is called the 定盘星 (dìngpánxīng, the "balance-marking star"). Without this mark, the scale is just two pieces of wood and a lump of iron, incapable of telling you the difference between one *jin* and one *liang*.
Tiantong Zhengjue (天童正觉) composed a verse on an old case using this everyday instrument: "When a fly alights on the scale's tip, it tilts; ten thousand generations of weighing cannot level the imbalance. When the very ounce and grain are seen precisely, in the end it all yields to my dìngpánxīng." Wansong Xingxiu (万松行秀) then unfolded these four lines layer by layer in his prose commentary, ultimately arriving at a place that would give pause to anyone clinging to "standards": "On the dìngpánxīng itself, there is originally no weight at all."
This is the complete landscape of the Chan concept of "定盘星." It is not merely a metaphor; it is a complete methodological framework of doctrinal judgment, a paradoxical wisdom about "how to have a standard without being bound by it."
I. What This Concept Is Saying
1. Starting with a Small Mark on the Scale Beam
Before entering Chan Buddhism, let us first clarify the physical nature of this "star." A traditional steelyard balance can weigh things only because of the coordination of three components—Wansong cites the *Shangshu Zhiyao Tushuo* (《尚书治要图说》) to explain the three meanings of the scale:
- 准 (zhǔn, the reference mark): The fixed engraved mark on the beam, which is the "dìngpánxīng" itself. It does not move; it is the frame of reference. - 衡 (héng, the beam): The beam itself. A wooden rod that can tilt up and sink down but can also be made to hang level. It is where "balance" takes place. - 权 (quán, the counterweight): The sliding weight. It slides along the beam and achieves balance through changes in position. It is where "adjustment" takes place.
These three things are indispensable: without the reference mark, there is no way to judge levelness; without the beam, nothing can hang suspended; without the counterweight, nothing can be adjusted. What makes a scale a scale is the whole of the three.
Ancient scales were extremely precise. Wansong enumerates in detail: **eight *zhu* make one *zi*; three *zi* make one *liang*; sixteen *liang* make one *jin*.** Even the slightest fraction of a *zhu* was discernible to the scale—this is the meaning of "when a fly alights on the scale's tip, it tilts": even a fly landing on the beam's end causes the scale to respond with a tilt. The sensitivity of the scale is the fundamental reason it can serve as "ten thousand generations of weighing."
2. Why Chan Buddhism Specifically Borrows the "Scale" to Speak
The image of the scale recurs throughout Chan literature, and this is no accident. It carries a distinctive methodological implication:
The function of the scale is to "illuminate imbalance." It does not create weight; it reveals weight. With a proper dìngpánxīng, if you place a piece of gold and a stone on it, it will not favor the gold nor sympathize with the stone; it will simply show which is heavier and which is lighter. What Chan Buddhism wants is precisely this quality—in judging the essential intent of the Buddhas and ancestors, in weighing right and wrong, one can be precise to the "grain and ounce" without ambiguity.
The first two lines of Tiantong Zhengjue's verse—"When a fly alights on the scale's tip, it tilts; ten thousand generations of weighing cannot level the imbalance"—establish the scale as a "tool for doctrinal judgment" in this sense. In the monastic community, when facing monks who come to ask about the Dharma, when facing disputes over "yes" and "no," when facing divergences in scriptural interpretation—either you can illuminate, or you cannot; your "scale" is either sensitive enough or it is just two pieces of wood.
The line "in the end it all yields to my dìngpánxīng" is the heart of the entire metaphor: no matter how precise the scale, no matter how the counterweight (权) moves, everything ultimately must return to a fixed mark—and if that mark did not exist, all "levelness" would be self-deception.
3. But—"On the Dìngpánxīng Itself, There Is Originally No Weight"
This is the deepest layer that Wansong's commentary uncovers, and it is also the layer most easily overlooked—and the most crucial.
The earlier discussion established the dìngpánxīng as a "fixed standard for judging essential intent," which sounds like advocating a rigid rule. But Wansong immediately breaks open the topic by citing various masters: "Grasp the meaning of the hook's tip; do not fixate on the dìngpánxīng. For on the dìngpánxīng itself, there is originally no weight."
This statement has three layers of meaning:
First, the dìngpánxīng itself is "empty." The engraved mark on the beam has no weight of its own. It is neither one *jin* nor one *liang*. It is merely the "zero point," the starting point of measurement, not the measurement itself. You cannot grasp the dìngpánxīng as a "standard answer"—once you grasp it, it transforms from a "reference point" into an "idol."
Second, the "meaning of the hook's tip" is the living thing. The hook at the end of the beam (the sliding end where the counterweight hangs)—what is its "meaning"? It is that dynamic capacity to move in the present moment and to level in the present moment. When a *jin* comes, it moves once and levels it; when a *liang* comes, it moves once and levels it; when a grain changes, it tilts accordingly. This capacity of "moving once and leveling" is alive, situational, impossible to fix in advance. This is what can truly weigh.
Third, "do not fixate on the dìngpánxīng" is a warning, not a dismissal. It does not mean you should have no standard; it means you should not fixate on the standard itself as something dead. If you grasp the dìngpánxīng as ultimate truth, you lose the "meaning of the hook's tip"—that flexible capacity for weighing. You turn from a working scale into a dead object fixated on a single mark.
4. Three Progressive Metaphors Pushing This Paradox to the Extreme
Wansong uses three metaphors to deepen this point further and further:
(1) The North Star dwells in its place— The Pole Star is always in that position, but it does not itself do the weighing. All the stars revolve around it, but it does not participate in the revolution. The dìngpánxīng is this kind of existence: "dwelling in its place"—it is the frame of reference, but it does not itself enter into the world being weighed.
(2) A starless scale lets anyone sell freely— If a scale does not even have a dìngpánxīng, anyone can use it, anyone can weigh arbitrarily. Of course this is a joke—but Wansong uses this joke to say: a scale with no standard at all is even worse than one clinging to a wrong standard. Yet the phrase "lets anyone sell" hints at a liberation: when you no longer fixate on any particular mark, the scale actually becomes open to all.
(3) In the double-six board game, one wins by trusting the dice— Double-six (双陆) is an ancient dice game. Wansong says that the true master does not stare rigidly at the board, but throws the dice with an open hand and wins by following conditions. Here there is an even deeper reversal: deliberate measuring is inferior to no-mindedness, which levels without effort. The more you deliberately try to "level," the more uneven it becomes; when you let go of the fixation on "I must level," everything is level everywhere. This does not mean the scale is useless; it means—in the end, the "scale" is not weighing with the scale, but weighing with the person. The precision of the scale depends on the quality of the person using it.
The progressive logic is: first establish the standard (dìngpánxīng) → then break the attachment to the standard (do not fixate on the dìngpánxīng) → finally flip to the immediate ease where "even breaking is unnecessary" (no-mindedness, no imbalance).
5. Samādhi (三摩地)—The Inner Ground of the Scale's Functioning
In Wansong's commentary there is a crucial connection that modern readers easily overlook: he identifies the Sanskrit 三摩地 (samādhi, translated as "等持" (děngchí, "equipoise"), meaning neither sinking nor floating, evenly upholding) as "the one that illuminates imbalance across ten thousand generations."
What does this mean? The state of "equipoise" in meditative concentration is a balance of neither sinking (lethargy) nor floating (restlessness). Drowsiness is like the scale sinking to one side; agitation is like the scale tilting up on the other; true concentration (samādhi) is the unmoving evenness when neither tendency is present.
This is the inner ground of why the "scale" can weigh. A scale can be precise to the grain, not only because of the physical properties of wood and metal, but even more because of that "hanging level" itself—the state displayed at the moment the beam comes to rest. What meditative concentration aims at is precisely this state: not leaning to this side, not leaning to that side, yet able to finely illuminate the difference between the two sides.
In other words: the dìngpánxīng is not merely a mark on the scale beam; it is also the symbol of the psychological state of "equipoise" itself. A person whose mind is drowsy and restless cannot use even the finest standard; a person whose mind is in "equipoise" naturally illuminates everything.
6. "My" Dìngpánxīng: Who Is This "I"
Tiantong Zhengjue says "in the end it all yields to my dìngpánxīng." This "my" deserves a pause.
It is not "your" dìngpánxīng, nor "the Buddha's" dìngpánxīng, nor "dogma's" dìngpánxīng—it is "my." This means: this standard must be internalized within oneself; it cannot be borrowed.
You can learn a set of standards from a teacher, you can memorize a pile of rules from the scriptures, but if those things have not become your own "dìngpánxīng," then you are merely using someone else's scale to weigh your own world—the scale and you are two separate things.
In the monastic tradition of master-disciple transmission, what is transmitted is not the "dìngpánxīng" itself (that engraved mark) but the "meaning of the hook's tip"—the capacity that enables you to live out your own dìngpánxīng. The gong'an of Fayan Wenyi (法眼文益)—"When the counterweight is moved to the very end of the beam, suddenly it drops and flips over"—speaks to this: when the counterweight is moved all the way to the extreme end of the beam, the entire system suddenly overturns. This is what happens when a student pushes the master's teaching to its extreme, discovers that it can no longer be relied upon, and only then becomes able to grow his own counterweight and find his own balance point.
7. Convergence with "Holding the Eye of Heaven and Earth"
In the same *Congrong Anlu* (《从容庵录》· *Book of Serenity*), Wansong has another passage on "把定乾坤眼" (bǎdìng qiánkūn yǎn, "holding the eye of heaven and earth")—which differs in name from "dìngpánxīng" but is identical in meaning. He says: "In the monastic community, people rush about amid the clamor of right and wrong. Without the eye that holds heaven and earth, all of it is seeing ghosts before a skull." Jiufeng (九峰), answering a monk's question, said, "Heaven and earth are within it," and "This is precisely the eye of heaven and earth."
"Holding the eye of heaven and earth" is the same meaning from another dimension: there must be an "eye" that can stabilize the entire judgment; otherwise you are merely spinning in the field of right and wrong, seeing nothing but illusions ("seeing ghosts before a skull").
Looking at the two metaphors together, "dìngpánxīng" emphasizes precision (what makes a scale a scale), while "holding the eye of heaven and earth" emphasizes wholeness (what makes an eye an eye). One is a mark, the other is a field of vision. The precision of the scale depends on the mark, but it also requires the weigher to have "eye"—to know what one is weighing, why one is weighing, and what to do with the result.
II. Walking Through It in Everyday Life
This concept is highly abstract, but applying it is not difficult. Let me select three scenarios that contemporary people experience daily and map each component of the scale strictly onto them, while also pointing out where people most commonly mis-map.
Scenario One: Judging the Truth of Something Amid a Flood of Information
Suppose you come across a news item with a shocking headline. Your first reaction is: is this true?
Step One: First admit you need a scale. Many people today say: "There's no such thing as truth; everyone has their own opinion." This sounds intellectually open, but in practice it amounts to saying—"I don't even want a scale." Without a scale, how do you distinguish "fact" from "impression"? How do you know you're being fed by an algorithm? How do you know that "I think this is true" is not actually "I wish this were true"? A person without a dìngpánxīng does not end up without standards; they end up being silently taken over by someone else's standards.
Step Two: Check the three components one by one.
- 准 (your reference mark): Do you have an internalized, repeatable standard for judgment? For example: "For any news without a firsthand source, I require at least two independent sources for cross-verification." Or: "For anything involving data, I must find the original data, not just secondhand interpretations." These are your dìngpánxīng. Its defining feature: it does not change with the topic, does not change with emotion, and can be used repeatedly.
- 衡 (your beam): Can you hold yourself level? "Holding level" means, when reading this news, can you temporarily set aside your preference—whether you hope it is true or false. This is the concrete contemporary form of "equipoise" (等持, samādhi): not floating (not carried away by the shocking headline's emotional charge), not sinking (not too lazy to check, just swiping past).
- 权 (your counterweight): Can you adjust your judgment according to the specific situation before you? Who published this news? Why now? What is the background? This is the counterweight sliding across different marks—"bring a *jin*, move once and level; bring a *liang*, move once and level."
Step Three: Beware the trap of "do not fixate on the dìngpánxīng."
The most common mistake here is: you establish a standard (such as "at least two independent sources"), and then you rigidly cling to that standard—anything that doesn't fit is automatically rejected. But—
- What if the two "independent sources" both cite the same third party's erroneous report? - What if the topic is not suited to being measured by "number of sources" at all?
This is the meaning of "do not fixate on the dìngpánxīng": you cannot turn your standard of judgment itself into the endpoint of judgment. The standard is the starting point (the dìngpánxīng), not the destination. What you want is the "meaning of the hook's tip"—that living capacity—not the "dìngpánxīng"—that fixed mark.
The most common mis-mappings: - Treating "having no preconceived position" as "having no position" (this is discarding the reference mark). - Treating "staying open" as "reaching no conclusion" (this is discarding the beam—it never hangs level). - Treating "critical thinking" as "doubting everything" (this is mistaking the counterweight for the reference mark—using the weight as the scale's mark).
Scenario Two: "Who's Right, Who's Wrong" in Intimate Relationships
You and your partner have a conflict. Both sides feel they are in the right.
In this scenario, what is the dìngpánxīng?
It is not the conclusion of "who's right and who's wrong"—that is where the counterweight comes to rest, not the dìngpánxīng.
The dìngpánxīng is that fundamental understanding you both share about "what a good relationship is." For example: "A good relationship is one where both people can grow." Or: "Truth matters more than comfort." Or: "Physical exhaustion is not a refusal." These are not conclusions about any particular quarrel; they are the bottom-line baseline of your relationship.
Without this baseline, every conflict becomes "I win, you lose" or "you win, I lose"—the scale never levels, because it has no fixed end at all.
The three components:
- 准: The relationship baseline you both mutually recognize. - 衡: Can you, at this moment, maintain levelness amid the emotion? Can you simultaneously hear what the other is saying and what you yourself are saying? This is the hardest "equipoise" to cultivate in contemporary life—not being carried away by anger, not being crushed by grievance. Many intimate relationships reach a deadlock because both beams have fallen—one floats up into shouting, the other sinks into cold silence; two crooked beams cannot produce a reading no matter how they are used. - 权: Can you respond differently according to the specific circumstances of this particular conflict—is the other person genuinely exhausted? Has your own past trauma been triggered?—rather than running the same script every time?
What does "do not fixate on the dìngpánxīng" mean here?
It means: you should not turn your "relationship baseline" into a weapon to attack the other person. "I think a good relationship should be X, therefore your behavior Y is wrong"—in this sentence structure, the dìngpánxīng has transformed from "reference point" into "club." When you use something you both mutually recognize to crush the other person, that dìngpánxīng is broken.
The true "meaning of the hook's tip" is that living capacity to find the balance point in every concrete conflict—it moves with the situation, but it does not lose the felt sense of "level."
The most common mis-mappings: - Treating "our principles" as the basis for "I'm right, you're wrong" (this is clinging to the dìngpánxīng). - Treating "putting yourself in the other's shoes" as "abandoning your own feelings" (this is mistaking the counterweight for having no reference mark at all). - Treating "I'm willing to communicate" as "I'm willing to concede" (this is mistaking the beam for having no counterweight).
Scenario Three: Self-Evaluation—"Am I Actually Good Enough?"
This is probably the most frequent weighing contemporary people perform. Every night before sleep, the scale comes out: Was today's work good enough? Am I too lazy? Am I disappointing people? Am I pretending?
What happens to a person without a dìngpánxīng?
Their counterweight is other people's evaluations, society's standards, the posts on their social feed—these things are constantly sliding, and their mind is constantly tilting up and sinking down. Praised today, the beam tips up; criticized tomorrow, the beam sinks down. There is never a moment of "level," because the beam has no fixed mark at all.
What happens to a person with a dìngpánxīng?
They have a baseline in their heart—not an external "how successful I should be" but an internalized "as a person who is still learning, did I honestly face myself today?" This baseline does not shift with external evaluations, but it is not rigid either—it adjusts its mark as one grows.
Here, "do not fixate on the dìngpánxīng" is especially important.
Many people, after practicing for a while, find their own baseline—such as "I must be sincere," "I must be compassionate," "I must live in the present"—and then turn this baseline itself into a new shackle. Every day they whip themselves with "Am I sincere enough?"
This is the contemporary meaning of "on the dìngpánxīng itself, there is originally no weight": "Sincerity" itself does not weigh you; "compassion" itself does not judge you; "living in the present" itself does not grade you. The moment you turn these standards into a scorecard, they transform from "dìngpánxīng" into "the counterweight that oppresses you."
The true "meaning of the hook's tip" is that capacity which, in the present moment, lets you say "today's me is simply today's me." This capacity needs no mark to support it—it is itself balance.
The most common mis-mappings: - Treating "personal growth" as "always feeling you're not good enough" (this is using a scale with no reference mark to weigh yourself). - Treating "self-acceptance" as "indulging yourself" (this is misreading "do not fixate on the dìngpánxīng" as "there is no dìngpánxīng"—but as stated above, a starless scale is worse than one clinging to a wrong mark: "letting anyone sell" sounds free, but in reality no one can sell a fair weight). - Treating "standards within" as "feeling good about yourself" (this is mistaking the reference mark for a self-deceiving counterweight).
III. Why Contemporary People Need It
1. We Live in an Era of "Standard Vacuum"
Since the second half of the twentieth century, traditional sources of authority—religion, the state, the family, the community—have to some degree been demystified. This is not a bad thing (often it is necessary), but it leaves a vacuum: there is no external authority giving us our dìngpánxīng anymore.
The consequence of this vacuum is not "people are freer" (that is the surface), but "people are more anxious" (that is the reality). Because a person without a scale does not thereby treat everything equally—they get attracted to anything that looks like a scale: extreme ideologies, influencer opinions, algorithmically recommended content, "life hacks" forwarded in group chats.
The concept of "dìngpánxīng" reminds us: freedom is not "having no standards"; freedom is "finding the standard that is internalized in yourself and alive." The former leaves you open to being taken over by anything; the latter is genuine freedom.
2. Does the Algorithm Give Us a Dìngpánxīng?
A particularly thought-provoking question for our time: is the algorithmic recommendation system giving us a "dìngpánxīng"?
On the surface, yes. The algorithm tailors an information environment "to your measurements" based on your behavioral history, your preferences, your dwell time. Within this environment, everything you see "matches you," everything feels comfortable, everything reinforces your existing judgments.
But this is precisely the kind of "standard" that the metaphor of the dìngpánxīng is meant to demolish.
Why? Because a true scale must be able to illuminate imbalance—"when a fly alights on the scale's tip, it tilts." A "scale" that only shows you the results you want to see is not a scale at all; it is a mirror. A mirror lets you see yourself the way you like, but it does not weigh.
The greatest trap of the contemporary information environment is mistaking the mirror for the scale. You think your standards are real, independent, "mine"—but in fact they are predictive models trained by algorithms on your past likes—that "I" is not a real "I"; it is a constructed echo chamber.
"定盘星" tells us: a true standard must be able to make you feel a certain degree of discomfort—because what it illuminates is "imbalance," and the imbalance within you necessarily includes the side of yourself you do not want to see.
3. The Modern Resonance of Samādhi: Why the Mind Must Be "Equipoised"
Wansong identifies samādhi (三摩地) as "the one that illuminates imbalance across ten thousand generations"—this is the key step that pulls the dìngpánxīng from "external mark" back to "inner state."
Contemporary psychology has a related but not identical concept called "mindfulness" (正念) or "metacognition" (元认知). Research shows that judgments made while the mind is calm are more accurate and less susceptible to manipulation than judgments made under emotional agitation. But this does not mean "Buddhism has been proven by science"—such empirical research can tell us why "equipoise" is useful, but it cannot tell us what the essence of "equipoise" is or what ultimate liberation it can bring. At this intersection we can only see echoes between the two traditions on certain dimensions, without forcing identity.
But the metaphor of the dìngpánxīng says something deeper: the precision of the scale depends on the state of the one wielding it. With the same scale, a restless person will misweigh, while a person dwelling in stillness can discern the difference of a grain. This is why the ultimate direction of the "dìngpánxīng" is not "find the correct mark" but "cultivate the quality that can use the scale correctly"—that is, samādhi, that is, equipoise.
4. Why Rigid Standards Actually Make People Anxious
Many people's first reaction to "Chan Buddhism talks about standards" is: "Isn't Chan against attachment? So why establish standards at all?"
This is a good question, and it is the key entry point for understanding the "dìngpánxīng."
The answer is: having no standard is worse than having a rigid standard. "A starless scale lets anyone sell freely" sounds free, but in reality it means—anyone can use your scale to weigh out whatever result they want. Your judgment has no anchor at all; you drift with the current, and your mind is never at rest.
But the problem with rigid standards is even greater—because they backfire. A person who desperately clings to "I must do X," when X cannot be achieved, either turns to self-negation or compels others. That "I must" itself becomes the source of anxiety and violence.
The wisdom of the dìngpánxīng lies here: establish the standard (准), but do not let the standard become yourself (do not fixate on the dìngpánxīng). This is a dynamic, flexible, living standard. It is like the North Star—always in that position, but never participating in your daily revolutions. It is like a mark that breathes—as your life grows, the mark itself adjusts, but it is always there, as a reference.
Contemporary people desperately need this quality. Because we are in a world where everything is accelerating in flux: careers change, relationships change, values change, bodies change. If your standard is rigid, you will be crushed by the times; if your standard does not exist at all, you will be scattered by the times. Only a "living standard"—that star which does not move yet does not cling—can keep you awake amid change.
IV. Common Misreadings and Clarifications
Misreading One: "Dìngpánxīng" Means Rigid Dogma, "My Truth"
This is the most common misreading, arising from looking only at the first two lines of Tiantong Zhengjue (the function of the scale) without looking at Wansong Xingxiu's subsequent unfolding.
If the dìngpánxīng were merely a rigid standard, then Chan Buddhism would be no different from the dogmatism it criticizes for "dying under the words." But Wansong explicitly says "do not fixate on the dìngpánxīng" and "on the dìngpánxīng itself, there is originally no weight"—the standard is empty in nature; it does not itself weigh. The moment you grasp the standard as a substantial entity, it breaks.
The correct understanding: the dìngpánxīng is a functional concept—its value lies in enabling the scale to work, not in how "substantial" it is itself. To worship it as an entity is the greatest betrayal of this metaphor.
Misreading Two: "Dìngpánxīng" Means "I Have Strong Opinions," "I Have High Standards"
Many people, upon hearing the term "dìngpánxīng," understand it as "having principles in life," "having a bottom line"—this is secularizing and diluting it.
What makes the dìngpánxīng what it is is not that it is "high" or "hard," but that it is "level." It is impartial, and only then can it illuminate imbalance. A person with "very high standards" may in fact be someone whose counterweight has been moved to the extreme (in Fayan's gong'an, "when the counterweight is moved to the very end of the beam, suddenly it drops and flips over")—that is not the dìngpánxīng at work; that is a danger signal before the dìngpánxīng breaks.
The true dìngpánxīng allows you to see that you yourself are also in imbalance—not only others are imbalanced; you yourself are part of the imbalance.
Misreading Three: "Grasp the Meaning of the Hook's Tip, Do Not Fixate on the Dìngpánxīng" = Having No Standard
This is a misreading in the opposite direction, arising from reading "do not fixate on the dìngpánxīng" as "do not have a standard."
But as stated earlier: "a starless scale lets anyone sell freely" is a joke, not a recommendation. A scale with no standard at all allows anyone to weigh out whatever result they want—this is not freedom; this is chaos.
Wansong's entire argument is dialectical: first establish (the dìngpánxīng), then break (do not fixate on the dìngpánxīng), then flip to a further layer (even breaking is unnecessary; it is naturally level). But these three steps cannot be reversed—you cannot skip "establish" and jump to "break," nor can you stop at "break" and think that is the endpoint.
The correct understanding is: a standard is necessary (establish), but the standard is empty (break), and what truly weighs is the living person (the flip).
Misreading Four: Understanding the Dìngpánxīng as External Authority or "the Buddha's Standard"
Tiantong Zhengjue says "in the end it all yields to my dìngpánxīng"—the character "my" is crucial.
The standard of Chan Buddhism has never been external authority in the sense of "what the Buddha said." Although Chan claims to be a "separate transmission outside the teachings," its critique of "interpreting meaning according to the text" is precisely a critique of "treating the scriptures as the dìngpánxīng." The true dìngpánxīng is what you internalize through your own practice—it is not in some book, not in some teacher's mouth; it is in how you use your scale.
This is also why Chan has the saying "not establishing words and letters, directly pointing to the mind"—not to negate words, but to say that words themselves cannot be the dìngpánxīng; at most they are a hint of the "meaning of the hook's tip."
Misreading Five: Conflating the Three Components of the Scale (准, 衡, 权)
This is a structural misreading. When contemporary people speak of "principles," "bottom lines," "standards," they often fail to distinguish levels, treating "准," "衡," and "权" as the same thing.
But Wansong, citing the *Shangshu Zhiyao Tushuo*, explicitly divides the scale into three components:
- 准 (the reference mark): What kind of standard is it? - 衡 (the beam's capacity for balance): Can you hold yourself level in the present moment? - 权 (the counterweight's capacity for adjustment): Can you adjust according to the specific situation?
There are three common confusions:
1. Treating 准 as 权: Applying a rigid standard to all situations indiscriminately ("a principle is a principle; there are no exceptions"). 2. Treating 权 as 准: Adjusting every time according to circumstances, with no bottom line at all ("handle each case on its own merits"—this sounds reasonable, but if there is nothing unchanging behind it, how do you know when to say "this is the bottom line"?). 3. Treating 衡 as 准 or 权: Thinking "my mind is calm" equals "I have a standard," or "my mind is calm" equals "I can adjust freely." In fact, holding level is an independent capacity—it neither presupposes a standard nor presupposes flexibility; it is simply the act of "being able to illuminate" itself.
Misreading Six: Thinking the "Dìngpánxīng" Is Unique to Chan Buddhism
Although this metaphor originates in Chan, its inner logic resonates in other traditions. For instance, the *Diamond Sutra*'s "应无所住而生其心" (yìng wú suǒ zhù ér shēng qí xīn, "one should give rise to the mind without dwelling anywhere")—that "mind that does not dwell" is another way of saying "do not fixate on the dìngpánxīng"; while "give rise to the mind" is that living capacity to "move once and level." Likewise, the *Heart Sutra*'s "照见五蕴皆空，度一切苦厄" ("illuminatingly sees the five aggregates as empty, and crosses beyond all suffering")—"illuminatingly sees" is the scale's function of illumination, and "all empty" is "on the dìngpánxīng itself, there is originally no weight."
This is not to say the three concepts are identical, but that in the vocabularies of different traditions, they point to the same depth: any genuine capacity for judgment must be both precise (illuminating imbalance) and empty (not dwelling in marks). Lose the former and you have nihilism; lose the latter and you have attachment. The metaphor of the dìngpánxīng preserves this tension completely and elegantly in the image of an everyday object.
Conclusion: The Unmoving Star, and the Living Person Behind It
The hardest thing to explain about the dìngpánxīng is that it simultaneously requires two seemingly contradictory things:
- You must have an unmoving reference point—otherwise you cannot weigh anything. - You must not grasp this reference point itself—otherwise it becomes a new idol.
This is not Chan sophistry; it is the structure of all genuine judgment. Consider:
- A judge must have the law (the unmoving reference point), but must not cling rigidly to the letter of the law (must make the "counterweight" move according to the specific situation). - A doctor must have medical knowledge (the reference point), but must not recite it mechanically (must make judgments for the specific patient). - A truly mature person must have their own values (the reference point), but must not use values as a club to crush others (must maintain the beam's levelness).
The mystery of the scale is that it can be precise to the grain and yet transcend all weights. It illuminates all things, yet it itself is not weighed among them. This is the dìngpánxīng, and it is also samādhi, and it is also that mind "that does not dwell anywhere" in the *Diamond Sutra*, and the very act of illumination in the *Heart Sutra*'s "illuminatingly sees the five aggregates as empty."
Tiantong Zhengjue's verse ends with "in the end it all yields to my dìngpánxīng"—the moment that "my" lands, the entire metaphor flips from "scale" to "person." The scale is a tool; the person is the ground of why the scale is a scale. You can borrow a scale from someone else, but the dìngpánxīng—that inner reference point that makes your scale work—must be your own. And when you truly find it, you will discover that it "originally has no weight"—it is not something you use to crush others; it is that which enables you to remain "level" amid all disturbance.
This "levelness" is not the deathly stillness of no waves, but the capacity to remain suspended even among the waves. The scale beam is always moving—the counterweight shifts, things are added, flies alight. But as long as the dìngpánxīng is there, the beam can always return to that suspended, level position.
This, in the end, is what the small Chan metaphor of the "dìngpánxīng" has to tell us.
