What This Concept Is Saying
The four characters "光不透脫" form a term the Yunmen school uses to diagnose an extremely subtle state — and what it diagnoses is not the confusion of a beginner, but the state of someone who has already glimpsed a bit of spiritual luminosity and touched a bit of emptiness and stillness. So these four characters should be read slowly, and then more slowly: they do not mean "there is no light," but "the light cannot pass through"; they do not mean "total darkness," but "something in the light is blocking it."
Yunmen divides this into two kinds of illness (兩般病), and these two are not parallel but rather two depths of the same leak:
The first kind of illness: "All places are unclear; there is a thing before the eyes." This is a state where "clarity" has not truly penetrated. Although you feel you have awareness and spiritual acuity, before your eyes — whether in the immediate present of sense-contact after sense-contact, or in your own reflective watching of your state — something stands. You look at the world, and the world is murky; you look at yourself, and yourself is blurred. Coarse attachments, obvious emotions, unprocessed wounds, unbroken views — all belong to this category. The "thing before the eyes" can literally be an objective object, psychologically a stuck knot, but its fundamental reference is: between you and clarity, there is still a layer.
The second kind of illness: "Having penetrated the emptiness of all dharmas, still faintly there seems to be a something." This is what Yunmen is truly alerting us to. This illness occurs after one has already "penetrated the emptiness of all dharmas" — you have seen emptiness, you have done the work, you have at some moment experienced "all dharmas are ungraspable." But, Yunmen says, within that emptiness, there is still "faintly a something." It has no shape, no name, no logical content — only a sense of existence that is neither quite there nor quite absent — a feeling that "something is there." You cannot say what it is, but you can feel it there.
This is the subtlest kind of leak in Chan Buddhism. Master Wansong, in his commentary on the *Cóngróng Record* (從容錄), quotes a line to characterize it: "縱滅一切見聞覺知，內守幽閑，猶為法塵分別影事" — even if you extinguish all seeing, hearing, sensation, and knowing, and within guard a quiet stillness, that still is a shadow-event of discriminating among sense-objects. Even if you have extinguished all external seeing, hearing, sensation, and knowing, and within there is a stretch of quiet stillness, as long as you are still "guarding within" — guarding that stretch of stillness — then this guarding itself, that stretch of "quiet stillness" itself, is a shadow-event of the mind's discriminating among dharma-objects. Nanyuan Yong describes this state: "Like walking within a lamp's shadow" — you think you are walking in light, but you are only walking within a lamp's shadow; that bit of light is not true illumination, it is an atmosphere you have manufactured yourself.
The character "光" (light) is especially worth chewing on here. Another Yunmen saying: "人人盡有光明在，看時不見，暗昏昏" — everyone has luminosity present; when you look for it, it is not seen, and all is dim. Luminosity is originally inherent; when you look at it, it does not manifest — this is the Chan底色 "not defiled, thus repaying kindness." So the "light" in "光不透脫" is not a luminosity acquired through practice, but the innate luminosity of the original mind; "不透脫" (cannot pass through, cannot be freed) does not mean the light is blocked, but that within the luminosity itself something still hangs, and that something prevents the light from completely passing through itself.
The two illnesses must be read together. The first illness is a thing before clarity; the second is a shadow within emptiness. The former is "having something attained"; the latter is "having attained emptiness, and the emptiness itself becomes an attachment." The first illness is coarse and manifest; the second is subtle and hidden. The second is a hundred times harder to recognize than the first — because it hides within what you take to be your purity, within what you take to be your letting go, within what you take to be "I have already arrived home."
Yunmen also connects these two kinds of illness with "the Dharma-body also has two kinds of illness":
One: "Having attained the Dharma-body, the dharma-attachment is not forgotten, self-view still remains, and one falls to the side of the Dharma-body" — you have indeed seen the Dharma-body, you have indeed had some experience of signlessness, selflessness, and non-attainment, but you "do not forget dharma-attachment": you have turned this view into your own possession; "self-view still remains": within you there is a self that thinks "I have seen it"; and so you "fall to the side of the Dharma-body" — you think you are inside the Dharma-body, but you are circling at its edge, unable to enter.
Two: "Having attained the Dharma-body and passed through, still you must look carefully — is there any breath remaining?" — even after you have passed through, you must still look back: is there any breath left? This "breath" is finer than everything before it. It is not attachment, not view, not emotion, but — that which Chan can hardly put into words — a sense of "I am," a residual trace of "something is happening now." It is the finest thread of your stream of consciousness itself.
Thus the *Record of Hongzhi* (宏智禪師廣錄) repeatedly urges: "照得徹，脫得盡" (illumine to the utmost, free to the utmost); "本光現前，透出光影，不容他物，徹底不掛毫髮" (the original light manifests before you; pass out through light and shadow; allow no other thing; to the very bottom, not a hair's breadth hangs). What is being described here is not a brighter, more sacred state, but a thoroughness in which "even traces are absent" — within light there must be no shadow; within seeing there must be no seer; within purity there must not be that little bit of "I know I am pure."
Master Wansong finally juxtaposes Yunmen's "two illnesses of the Dharma-body" with Qianfeng's "three illnesses of the Dharma-body," summarizing what the Chan school collectively discusses as three illnesses: "未到走作、已到住著、透脫無依" — before arriving, running about; having arrived, dwelling in place; having passed through, still without reliance.
- "未到走作" (before arriving, running about): not yet arrived, and everywhere grasping at states; - "已到住著" (having arrived, dwelling in place): arrived, and stopping there; - "透脫無依" (passed through, yet without reliance): even having passed through, unwilling to truly let go — the two characters "透脫" themselves become a new cage.
Yunmen's two illnesses are established from the latter two: "已到住著" is the first layer of the second illness (falling to the side of the Dharma-body); "透脫無依" is the second layer of the second illness (is there any breath remaining). The first, "未到走作," is omitted, because those Yunmen seeks to treat are not people who have not yet begun the path, but those who, having begun, find that the deeper they go, the harder their illness is to see in themselves.
The core of the remedy is summarized by Master Wansong in one sentence: 「出不隨應，入不居空，外不尋枝，內不住定。」 Going out, do not follow the responses of objects; entering, do not dwell in inner emptiness; externally, do not seek among branches; internally, do not fixate in absorption. If one can do this, then "the three illnesses and the two lights are all at once passed through and freed." But Master Wansong adds immediately: even the names "passed through and freed" and "not passed through and freed" must be set aside. If, when you check, you can still sense "some breath," that breath itself is the illness.
— This is the final standard Chan sets for one who has truly practiced to the end: even the trace of "I have arrived at the practice's end" must not remain.
Master Wansong closes with a rhetorical question: "還見麼瞎" (Do you still see? — Blind). You want to see? — Blind. This "blind" is not pitch darkness, but luminosity reaching a place where it can no longer be described by "seeing." It cuts off all "light" that can be looked at, grasped, or rested in.
A Walk-Through in Everyday Life
Bringing these two illnesses back to contemporary life, we can walk through them step by step using familiar scenarios. Note: what Chan calls "光不透脫" originally points to a subtle state within practice; the mappings below should stay as close to the original meaning as possible, and we should not paste this label onto every confusion — it refers specifically to those who have already seen something and done some work.
What the first illness looks like in life
You and your partner have a recurring old problem — for example, he or she is always late, or always stops listening to you on a certain topic. On the surface you know it is not a big deal, but every time the moment arrives, the "fire" still rises.
This is "all places are unclear; there is a thing before the eyes." The "thing before the eyes" is that fire, that "I," that "should." You are not lacking in luminosity — you have read many books, attended many courses, know that when emotions arise you should observe them, know that relationships need space, know that the so-called "I" is not the real I — but, when the thing happens, you clearly see yourself failing to pass through again. You clearly have light, but the light cannot pass through this mass.
This is Yunmen's first illness, the common state shared by beginners and by those who have practiced for many years alike. It is manifest, it is coarse, it can be named. Once you can name it, the direction of the work is clear: not to make yourself emotionless, but to let the light truly shine into that mass.
What the second illness looks like in life (this is the key point)
Suppose you have done a year of vipassanā, a hundred days of meditation retreats, finished *The Power of Now*, attended several deep psychological workshops, and you have had a few moments of "nothing left." You have learned to stop when emotions arise, to ask "who is angry?", to not grasp. You even often feel light, clear, and unblocked in daily life.
— At this point, Yunmen would say: hold on.
Very likely, without your noticing, you have developed a new "I." This "I" is not the original small self, but a "small self that has let go"; not the original tense identity, but an identity of "I am no longer tense." Its signs: you can now speak about past suffering very calmly; you begin to use sentences like "I used to get stuck here, but now I don't"; you even begin to be able to demonstrate a state of "transparency" in front of others.
This is "dharma-attachment not forgotten, self-view still remaining, falling to the side of the Dharma-body." You have really let go of many things, but you grip "letting go" itself tightly in your hand. You think you are inside the Dharma-body, but you are carefully circling at its edge, maintaining it, proving it.
Even finer is that "faintly there seems to be a something." For example, you are walking alone in a park, with no particular emotion, sunlight on your face, and you feel a clarity. You notice yourself in the clarity. Then the clarity is still there, but something extra has appeared — not attachment, not thought, but a faint echo of "oh, I am very clear right now." Or: after sitting meditation you feel emptiness and stillness, and within that emptiness there is a thin trace of "this is real." Or: you have just handled a very difficult matter and you feel "I handled that really well" — that faint feeling of "handled well" — Chan would point at it and say: "This is it."
It really is extremely subtle. So subtle that by the time you can point it out, it has already gone; and yet it is always still there. Nanyuan Yong's metaphor "like walking in a lamp's shadow" — you think you are in the light, but you are walking in the halo of light you yourself project; the light is always slightly larger than the place where you actually stand. The "emptiness" you experience is missing just a little something from true emptiness; that "little something" is the breath.
Several concrete scenarios in contemporary life
- A state common among long-term meditators: being able to point out very calmly that "others still have attachments," but equally unable to point out one's own blind spots. "Self-view still remaining" is this gentle barrier of "can see others, cannot see oneself." - "Spiritual bypassing": using "everything is emptiness," "don't judge," "the universe has its own arrangement" to avoid concrete discomfort and concrete relational responsibility. This is the most common modern version of turning "emptiness" into "falling to the side of the Dharma-body." - The subtle trap after long-term self-growth and long-term psychotherapy: self-awareness becomes very strong — you can name, reflect, deconstruct — but "being able to deconstruct" itself becomes a new identity. You begin to appreciate your own reflection, appreciate your own vulnerability, appreciate the way you look "without attachment" — every kind of appreciation is a grain of dust at the side of the Dharma-body. - After long-term mindfulness practice: you can taste the rice while eating, feel the soles of your feet while walking, but the awareness itself gradually becomes a "homework," something that must be done correctly, a practice that gets checked as "how did I do today?" — at this point awareness is no longer awareness; it is "my awareness."
Where it is easiest to map wrongly
The public most easily maps this concept onto two things:
1. "I'm not in a good state today / my emotions are unsteady": this is only ordinary fluctuation and does not lie on the same level as the two illnesses Yunmen established; 2. "I'm not enlightened enough yet": this is also off. "光不透脫" does not mean "not yet enlightened," but rather after having enlightened to a certain level, is the leak at that level still there or not. What it diagnoses is the practitioner, not the ordinary person.
Another easy place to map wrongly is taking "emptiness" as the destination. What Yunmen says is that after "penetrating the emptiness of all dharmas," there is still illness. This means: when you are pursuing "emptiness," you are very likely feeding another kind of attachment. When you take "emptiness" as the highest goal, that "I who pursues emptiness" is the breath.
Why Contemporary People Need It
What contemporary people do not lack is "the language of awakening"; what they lack is knowing nothing about which level they are actually on, which illness they are actually in.
Our era is the era of the "enlightenment economy" — the market circulates various versions of presence, the now, non-judgment, letting go, returning to the original mind, living in each moment. Not one of these sentences is wrong, but they are being consumed at an astonishing speed. When you read *The Power of Now*, do a few breathing exercises, watch a few videos about the "ego," you may very well at some moment feel "I understand." This very "I understand" itself may become a new cage.
Yunmen's two illnesses provide this era with a very cool mirror:
First, it cuts "clarity" apart from "ignorance" with a single stroke. The public often thinks that "not practicing well" means not enlightened, and "enlightened" means everything is clear. But Yunmen says: even when you have seen the light, there may still be a thing in the light; even when you have penetrated to emptiness, there may still be a shadow in the emptiness. This turns "enlightenment" from a noun into a process that must forever be re-examined — at no moment can you say "I have reached the bottom."
Second, it precisely points out where contemporary practice most easily falls — the "light" becomes a soft couch. The three illnesses named by Qianfeng — "before arriving, running about" corresponds to the beginner's restlessness; "having arrived, dwelling in place" corresponds to the middle stage's resting; "passed through, yet without reliance" corresponds to the trap of "having rested, falling back into resting." Contemporary people often skip the first two illnesses and stop directly at the edge of the third — we have heard "do not dwell" so many times that we develop a posture of "deliberately not attaching," and this very posture is itself an attachment. This is the most direct portrait of Yunmen's two illnesses in the contemporary world.
Third, it points to a work deeper than "cognition." Contemporary psychology has many resources — mindfulness, ACT, insight-based therapy, self-determination theory — they are all treasures, but they share one boundary: they are all languages about "thoughts" and "emotions," whereas what "光不透脫" points to — that "faintly there seems to be a something" — lies precisely beneath thoughts and emotions, at the finest layer of the stream of consciousness itself. This layer cannot be touched by cognition, cannot be named by language, cannot be dissolved by reflection. What it demands is not a cleverer awareness, but a letting go that abandons all awareness — and this is precisely what contemporary people find hardest. We must grip even "letting go."
Fourth, it pulls the measure of practice from "states" to "habit-energy" (氣習). People who study Buddhism easily chase states — emptiness, clarity, wisdom, signlessness. But the remedy in the *Record of Hongzhi* requires "轉却氣習" (turning over the habit-energy). States may exist; habit-energy must be turned. The state may arrive; the habit-energy may not yet have turned. This is why Yunmen makes "is there any breath remaining" the last illness — because no matter how many states, how high they are, if that subtle self-maintenance in you, that thin "I have practiced well," is not dissolved, you have never passed through.
One finding from contemporary brain science can serve as an aid to understanding: neuroscientists have found that even in a "resting state," the brain exhibits activity in what is called the "default mode network" — the circuit that continuously generates "self-narrative," organizing immediate experience into "my past, my present, my future." Meditation training can weaken it, but cannot make it disappear — it transforms, and continues to work in more refined ways: the very fact that "I have no self-narrative right now" can itself become a self-narrative. This has a remarkable resonance at the phenomenal level with Yunmen's "faintly there seems to be a something" — but it must be noted that this analogy stops at the phenomenal level. Brain science describes the activity patterns of neural circuits; what Chan calls "habit-energy" is the most subtle residue of the whole body-mind's accumulated habits and attachments. The two cannot be directly equated; forcing Buddhist concepts into the framework of neuroscience may aid understanding, but may also narrow it.
Common Misreadings and Clarifications
Misreading One: "光不透脫" just means "not yet enlightened"
This is the most common simplification. It is wrong. This term refers specifically to those who already have a clear view of luminosity and have already done the work. Both of its two illnesses are "illnesses that come after having something." Diluting it to the level of "you don't understand yet" is to dilute this precious diagnostic tool into an ordinary "you haven't finished practicing." Its power lies in this — it says: you already have it, but within what you take to be "having it," there is still one finest thing.
Misreading Two: "光不透脫" is negative and should be immediately eliminated
Also a misunderstanding. "光不透脫" is a diagnosis, not a curse. It points out where you currently stand, letting you know: which level your view has reached, which level is still missing. It can also be compassionate — it means you are already walking on the right path, not on a wrong one. Chan masters use this kind of diagnosis because they see that students' illnesses differ, and the prescriptions differ accordingly. The utterance of "光不透脫" is itself half the treatment.
Misreading Three: thinking "光" = "bright, pure, sacred" and "不透脫" = "unclean, attached"
Reading these two characters as a good/evil binary would miss Yunmen's point entirely. "光" here is the innate luminosity of the original mind, not a sacred state acquired through practice. That "光不透脫" can occur even after "penetrating the emptiness of all dharmas" means emptiness itself may also fail to pass through. This relativizes "light" and "emptiness" together: if you cling to clarity, clinging to clarity becomes illness; if you cling to emptiness, clinging to emptiness becomes illness; even if you cling to "non-clinging," clinging to "non-clinging" is still illness. This is the most counter-intuitive and most profound point of Chan: no state whatsoever can by itself guarantee your passing through.
Misreading Four: taking "habit-energy" or "breath" as some mystical state
When Yunmen and Master Hongzhi say "is there any breath remaining," they do not mean some mysterious thing is hidden there; they mean — can you detect in yourself any subtle inertia, the thinnest layer of self-maintenance? In life it is that faint self-satisfaction of "I did well," that faint confirmation of "I have already let go," that faint self-appreciation of "I am very quiet right now." These are all "habit-energy." Master Hongzhi says to "turn them over," not because they are dirty, but because they keep you from passing through.
Misreading Five: thinking that after "passing through" everything is fine
Master Wansong is very alert on this point: "even 'passing through' and 'not passing through' must be set aside." This means — even if you have truly passed through, you will still have a trace of "I have passed through." This trace itself is the illness. So what Chan calls "passing through" is not a terminus but a state that must forever be guarded against. Yunmen's final "還見麼瞎" is precisely a knock at this point: you really want to see? — When truly seeing, there is no "I see," no "light," no "passing through"; even this is blind. This is why Chan says "生出其心而無所住" — it does not mean "dwelling in a state called non-dwelling," but that you should not grasp even those three characters "無所住" (non-dwelling).
Misreading Six: using "光不透脫" to judge others
The easiest and most dangerous misreading. When Chan masters use this diagnosis on their disciples, it is extremely subtle work within the practice context; when the public gets hold of a concept, the easiest thing to do is use it to label others: "you are 光不透脫." Yunmen is absolutely not telling you to do this. Being able to see that little bit of "breath" in yourself is already very difficult; seeing the "breath" in others and taking pride in it is a coarser attachment.
A closing note: Master Wansong's commentary on the *Cóngróng Record* closes this gong'an with the phrase "還見麼瞎." This is not a blow, but the deepest reception — it cuts off everything you could grasp, leaving you in that place of no object and no relation. What Yunmen's two illnesses ultimately seek to treat is not making you brighter, emptier, or more transparent, but making you realize: even "clarity" itself is not something you can guard. What contemporary people most need may not be more knowledge about "awakening," but this deeper vigilance: at any moment, in your purest instant, you may quietly hide a single grain of dust.
