There is a moment many people know but rarely name: you wake up, your hand reaches for the phone before your feet touch the floor, and within sixty seconds the mind is already somewhere else — caught in someone else's outrage, someone else's vacation photo, the news ticker that won't stop ticking. By the time you brush your teeth, "you" are not really there; you are a thin slice of attention being dragged across a thousand small screens.
The Chan (Zen) term 光明寂照 (guāngmíng jìzhào) is, in a sense, a precise description of what is missing in that moment — and a precise description of what is *already* there behind it. The phrase comes down to us in the Song-dynasty compilation 《古尊宿語錄》 (Gǔ Zūnsù Yǔlù, "Recorded Sayings of the Venerable Ancients"), CBETA X1315, and it sits inside one of the most carefully worded lines in the entire Chan record:
「光明寂照徧河沙……慎勿於中論爾汝。」 *Luminous quiescent illumination pervading like the sands of the Ganges … be careful not, within it, to discuss "you" and "me."*
This single sentence, plus the two companion passages that orbit it, is the entire doctrinal source for what follows. Every careful word matters, and the first task is to walk through them as the text itself means them — not as contemporary intuition would have us read them.
一、这个概念在说什么
1. 一句话定义如何拆开读
The compound 光明寂照 is not a loose phrase. It is a deliberately stacked image, and the meaning shifts as you reorder its parts.
- 光明 (guāngmíng) — luminosity. Not photons, not a vision of white light, not the special experience some meditators report during deep absorption. *光明* here is the innate clarity of mind — the fact that there is *something it is like* to be aware, the sheer givenness of knowing. The text pairs this with 照, so 光明 is essentially *照 from the noun side*: illumination as quality, not illumination as act.
- 寂 (jì) — quiescent. The character carries a long Buddhist pedigree: 涅槃 (nirvāṇa) is sometimes glossed as 寂, 止 (śamatha, calm) is 寂, the *śamatha* of the meditative stilling. But the text is emphatic that 寂 here is not 暗 (darkness) and not 昏 (dullness). When it says 「離念性虛明, 居此常寂照」, the point is that 寂 and 明 arise together: stillness that is *also* luminous, like a still pool that is also transparent.
- 照 (zhào) — illuminate, shine upon, reveal. Again, not a metaphor borrowed from a flashlight. 照 is the unobstructed knowing of phenomena as they appear, without grasping, narrating, or fixing them. The text describes this function as 「剖判彰神用, 觀瞻洞覺明」 — discernment that displays spiritual function, looking-into that penetrates awakened clarity.
- 徧河沙 (biàn héshā) — pervading like the sands of the Ganges. A traditional image for *innumerable*. The luminosity is not localized to one spot — not "inside the skull," not "in the heart-center," not "in this special moment." It is coextensive with the field of experience itself.
- 慎勿於中論爾汝 (shèn wù yú zhōng lùn ěr rǔ) — be careful not, within it, to discuss "you" and "me." This is the clause most modern readers skip past, and it is doing the heaviest moral and contemplative work in the entire line. The luminosity is pervading; the moment you erect a "you vs. me" — me the inner experiencer, you the outer obstacle — you have re-clothed the bare field in the very dualism the line was dissolving.
2. 围绕核心的七个术语面
The same text uses a small constellation of terms to describe this one reality from different angles. They are not synonyms; they are facets of the same diamond, and misreading one as another is the first place contemporary readers go wrong.
| Term | Where it appears | Facet it lights up | |------|------------------|--------------------| | 光明寂照 | 「光明寂照徧河沙」 | The full expression: luminous + still + illuminating, pervading everywhere | | 常寂照 | 「離念性虛明, 居此常寂照」 | The *constancy* of this illumination — it does not flicker on and off | | 性虛明 | same line | Its *nature*: empty (虛) yet luminous (明) | | 圓光 | 「萬象圓光中, 清淨同一妙」 | Its *shape*: not a beam, but a sphere in which all phenomena rest | | 靈源 | 「靈源本不生」 | Its *root*: the "spiritual source" that is described as originally unborn | | 神用 | 「剖判彰神用」 | Its *function*: discerning activity that does not come from ego | | 覺明 | 「觀瞻洞覺明」 | Its *knowing quality*: penetrating awakened clarity | | 法忍力 | 「無非法忍力」 | Its *sustaining power*: the patience/strength to bear the dharma-reality |
The critical thing to notice: 寂 is never alone, and 照 is never alone. They are not two qualities that happen to coexist; they are one quality seen from two directions. The text is at pains to say this, and the reason becomes clear in the next passage.
3. 對境而能常寂, 應事而不失寂
The third passage is the one most often overlooked, and it is the one that prevents 光明寂照 from being misread as withdrawal or dissociation:
「對境心常寂, 靈源本不生。 事隨高下應, 機逐淺深評。 剖判彰神用, 觀瞻洞覺明。 無非法忍力, 更莫外求聲。」
Read carefully:
- 對境心常寂 (duì jìng xīn cháng jì) — facing objects, the mind is constantly still. This is not the empty gaze of dissociation. "Objects" here means *the entire field of presentation* — sights, sounds, demands, other people, your own thoughts. Facing all of them, the mind remains still. The still is precisely the *facing*, not the flight from.
- 靈源本不生 (líng yuán běn bù shēng) — the spiritual source is originally unborn. The 寂 is not the residue of some event that stopped. It is the very ground, and that ground has never come into being. This is what protects the teaching from becoming a story about achieving a special state.
- 事隨高下應, 機逐淺深評 (shì suí gāo xià yìng, jī zhú qiǎn shēn píng) — *affairs respond according to their level; capacities are assessed according to their depth.* This is the line that most directly addresses anyone who fears that 寂照 means passive mush. The mind that is 寂 *does* respond, and it does so with discrimination: it tunes itself to the matter at hand (高低) and to the person in front of it (機). There is no question that something is happening; the question is only what kind of something.
- 剖判彰神用, 觀瞻洞覺明 (pōu pàn zhāng shén yòng, guān zhān dòng jué míng) — *discerning reveals spiritual function; observing penetrates awakened clarity.* 神用 is not ego-driven cleverness; it is the responsive intelligence that arises precisely because there is no ego-clutching in the way. 覺明 is the same seen from the other side: the clarity with which one sees.
- 無非法忍力, 更莫外求聲 (wú fēi fǎ rěn lì, gèng mò wài qiú shēng) — *all is none other than the power of dharma-patience; do not seek the sound elsewhere.* 法忍 (dharma-ṣānti / dharma-pātī) is the capacity to bear the dharma-reality — most pointedly, the anutpattika-dharma-kṣānti, the patience of the non-arising, the spiritual "muscle" that does not flinch from seeing things as they are. The last phrase — *do not seek the sound outside* — closes the loop: the luminosity you are looking for is not in some external teaching, image, teacher, or experience. It is what is doing the looking.
4. 把这个概念放进整个解脱道
It helps to know where 光明寂照 sits in the wider map, because most contemporary readers will encounter the *adjacent* vocabulary long before they encounter this phrase.
- 般若 (Prajñā) lineage. The Heart Sūtra's famous 「照見五蘊皆空, 度一切苦厄」 ("illuminating, the five aggregates are seen to be empty, all suffering is crossed over") is the 照 side of the same coin. Prajñā is precisely this: the seeing that does not fix what it sees.
- 六祖《壇經》 parallel. Huineng's 「何期自性, 本自清淨; 何期自性, 本不生滅; 本自具足; 能生萬法」 echoes the structure exactly: *originally pure* (清淨 = 寂), *originally unborn* (本不生滅 = 靈源本不生), *originally complete* (本自具足 = 光明周遍), *able to produce all dharmas* (能生萬法 = 照而能應).
- 天台 (Tiantai) 三觀 (Three Contemplations). In Tiantai's mature framework, 空觀 illuminates emptiness (照寂), 假觀 illuminates conventionality (照俗), and 中觀 — the contemplation of the middle — is precisely 寂照同時 (jì zhào tóng shí): still *and* illuminating *at once*. 光明寂照 is the lived experience of 中觀.
- 《大乘起信論》 framework. The *Awakening of Faith* speaks of 一心 opening into two gates: the gate of the true suchness of mind (心真如門, where 寂 lives) and the gate of arising-and-ceasing (生滅門, where 照 operates). Crucially, these two gates are said to be 「不二而二, 二而不二」 — non-dual yet appearing dual, dual yet non-dual. 光明寂照 is the *thing itself* of which the two gates are the analysis.
- 《金剛經》 echo. 「應無所住而生其心」 — *the mind should be given rise to without dwelling anywhere.* 無所住 is 寂; 生其心 is 照. The Vajracchedikā does not say "don't have a mind." It says: have a mind that doesn't stick.
So 光明寂照 is not a private Chan neologism. It is the experiential name for what all these classic texts are pointing at from their different angles — and it is unusually *compact* about pairing the two sides without letting either collapse.
5. Two warnings the text itself flags
Two cautions are baked into the passages and they are worth raising before the walk-through:
1. Don't mistake 寂 for 枯木 (kū mù, "dead wood"). The Chan record is full of warnings against the 枯木禪 — a "stillness" that is just numbness, an "emptiness" that is just cold. The text's insistence that 寂 is *also* 覺明 is precisely the antidote: a still mind that is no longer aware has lost the illumination, and what is left is not liberation but stupor.
2. Don't mistake 照 for 想像 (xiǎngxiàng, imagination) or 攀緣 (pānyuán, grasping). The luminosity pervades "like the sands of the Ganges" precisely *because* it is not directed at any one thing. The moment 照 becomes *picking out this, dwelling on that*, it has collapsed into the ordinary stream of cognition the line was trying to describe from the outside.
二、生活里的走查
The danger of a phrase like 光明寂照 is that it sounds like an instruction for special occasions. The classical text is saying the opposite: this is what is already going on in every moment that you happen to notice it. The way to test the definition is to take a few ordinary scenes and walk the definition through them, term by term.
I'll use five scenes that recur in most contemporary lives. Each one is mapped against the classical components, and I'll flag the spots where people almost always mis-map.
Scene 1 — 醒来的第一分钟 (the first minute after waking)
You open your eyes. Before you have formed a single deliberate thought, there is *something it is like to be awake*. Colors, sounds, the weight of the blanket. This is the field. Then, very fast, the field gets overlaid: phone screen, notifications, an email, a news headline, a worry about a meeting. The inner narrator says "Ugh, already five unread" and a small tightening in the chest appears.
離念 (lí niàn, apart from thought): This is the precondition the text names. It is *not* "stop thinking." It is the capacity to be present to that first second of field-without-narrator and to notice when the narrator re-enters. The narrator is not the enemy; 離念 is the *unclenching* of identification with the narrator, so that you can see it as content rather than as "you."
性虛明 (nature is empty-yet-luminous): The field before the narrator is *虛* — open, not filled with a self — and *明* — already knowing, already appearing. That quality does not go away when the narrator starts. It just gets covered. Notice the difference between *what is happening* (the screen is bright, the body is tired) and *the story about what is happening* (I can't handle today, why did I sleep so badly).
Common mis-mapping: People hear "離念" and try to "have no thoughts." That is not 離念; that is a fight, and fights are themselves thoughts. 離念 is closer to *looking at a movie and realizing you are in the audience, not the screen*. The movie is still playing.
Scene 2 — 通勤路上被加塞 (cut off in traffic)
Someone swerves into your lane. The body reacts before thought: jaw clenches, heart rate jumps, a flash of "idiot, learn to drive." Then a small internal courtroom convenes — *that* driver is wrong, *I* am right, this ruined *my* morning.
對境心常寂: "Object" here is the other car, the close call, the insult to your sense of order. The text says that facing the object, the mind can remain *常寂* — constantly still. That does not mean suppressing the adrenaline. It means the *knowing* of the anger does not get colonized by the anger. You can feel the adrenaline in the body and still be the one who knows you feel it.
慎勿於中論爾汝: This is the line that lands hardest in traffic. The moment you set up *that driver (that)* against *me (this)*, you have split the field. The text is not saying the other driver is fine; it is saying that *within* the luminosity that pervades the situation, the "you vs. me" structure is a category error. There is traffic. There is a body in traffic. The "you" who is angry at the "you" who cut you off is a third thing that the text says does not actually exist in 圓光.
Common mis-mapping: "Don't discuss 爾汝" gets misread as "don't judge." That is wrong; the text is more radical than that. It is saying the very *pair* (you/me) that makes judging possible is what the luminosity does not support. This is uncomfortable, because the entire moral economy of "I was wronged" depends on the pair. But notice: 光明寂照 does not say no one was wronged. It says the *framework* of self-and-other is not what is fundamentally going on.
Scene 3 — 下午两点, 突然出事 (a sudden work crisis)
A client escalates, a system breaks, a small mistake snowballs. Within thirty seconds you are flooded: adrenalin, blame ("whose fault is this?"), planning ("we need to do X, Y, Z"), self-image ("if I had caught this earlier…"). The cognitive load is enormous.
靈源本不生: Try, even for a moment, to notice *that there is a place from which this entire storm is being watched*. The storm is real — the client really is angry, the system really is broken. But the watcher-of-the-storm was not produced by the storm. It is the 靈源, the spiritual source, and it is *originally unborn*. Recognizing it does not mean denying the storm. It means recognizing that *you* (as the locus of perception) are not the storm.
事隨高下應, 機逐淺深評: This is the line where 神用 and 覺明 become operational. *Discerning reveals spiritual function.* Because the source is not in panic, discernment becomes available: which of the ten things screaming for attention is actually urgent, which is noise, which matters most for the *person* in front of you (機, "capacity/root-condition"). 光明寂照 is not the absence of triage; it is triage that is not contaminated by the inner storm.
法忍力: Here is where the harder side of the phrase becomes real. 法忍力 is the strength to *bear* the dharma-reality of the situation, which includes its genuinely uncomfortable aspects. It is not stoic endurance of suffering; it is the willingness to *be present with what is true* — including the truth that you cannot fix everything in five minutes. Notice: this is precisely what contemporary psychologists call *distress tolerance*, except that 法忍 does not frame itself as a coping skill. It frames itself as a kind of spiritual strength that arises from the 靈源.
Common mis-mapping: People try to substitute "positive thinking" for 法忍力. Positive thinking is a story about the situation. 法忍力 is the capacity to look at the situation *as it actually is*, with all its sharp edges, without flinching out of the looking.
Scene 4 — 亲密关系里的一次小争执 (a small argument with someone close)
You and your partner disagree about something minor — a household task, a phone call, a tone of voice. Within seconds the conversation has become about *who is being unreasonable*. Both parties are now defending their own reasonableness and cataloguing the other's failures. The content of the original disagreement has been almost entirely lost.
圓光同一妙 (perfect light, pure and sharing the same wondrousness): This line — 「萬象圓光中, 清淨同一妙」 — is the line that most directly refuses the "you vs. me" of intimate conflict. "All phenomena within the perfect light" includes *you*, *your partner*, *the irritation*, *the memory of last week's argument*, and *the desire to be right*. The text says these are not opposed phenomena; they are all phenomena resting in the same light. They are 清淨同一妙 — pure, sharing the same wondrousness. This does not mean they are identical; it means they are not the kind of things that need to be on opposing sides.
剖判彰神用: The 圓光 does not abolish discernment. Within it, 神用 (spiritual function) can still operate: the discernment that *now* is not the moment to win the argument; that what is actually needed is to name what is happening without blame. 照 is not absent in conflict; the question is whether the illumination is owned by ego or not.
Common mis-mapping: "All phenomena share the same wondrousness" gets misread as "nothing matters, so just agree." That is precisely the false 寂 the text is warning against. 同一妙 does not mean "the same content." It means they are all resting in the same light — and *from within that light*, discernment about what to do is not only possible but more reliable than discernment-from-within-ego.
Scene 5 — 坐垫上的十分钟 (ten minutes on the cushion)
You sit down to meditate. You try to follow the breath. Within ninety seconds you realize you have been thinking about lunch. You try harder. You get more agitated. You "fail." You judge yourself for failing.
寂 vs. 止 (śamatha): Here is where the most common meditation-misreading happens. People experience 止 as "the mind got quiet," and they report "I had a moment of stillness." But 止 is *concentrated* stillness — a stillness that is *directing* attention at one object. 光明寂照 is a very different stillness. It is not the stillness of a focused laser; it is the stillness of an empty room in which sounds can be heard clearly. The text's 寂 is paired with 照 *because* 照 is exactly what is *missing* in a still-but-narrow state.
照 vs. 想 (perception/thinking): Some practitioners try to cultivate 照 by *visualizing light*, by *trying to feel* clarity, by *producing* an open spacious feeling. The text calls this *外求聲* — seeking the sound outside. 照 is not an object you can produce. It is the unobstructed knowing that is present even (and especially) when nothing special is being experienced.
Common mis-mapping: The single most common error in contemporary meditation culture is treating 光明寂照 as a *goal*. People want the experience of "luminous stillness" — they chase it, they look for it, they get frustrated when it doesn't come. But the text explicitly says the luminosity already pervades. The work is not to produce it; the work is to *stop obstructing it*. (This is also why the text ends 「更莫外求聲」 — *do not seek the sound elsewhere* — including in your own private experiences.)
三、当代人为什么需要它
It is fair to ask why a tenth-century Chan phrase is worth a contemporary reader's time. Three reasons stand out, and they are worth being honest about.
1. Attention has been colonized
The most distinctive feature of contemporary life is the attention economy: the entire digital infrastructure is engineered to capture the 照 function and redirect it toward commercially-chosen objects. Every app, every notification, every autoplay video is a small attempt to take over your awareness. The classical text's claim — that the luminosity *already pervades*, and that you should not set up "you vs. me" within it — turns out to be almost a direct description of what is being attacked. The 光明寂照 is the awareness that the app is *trying to rent*, and the recognition that you do not have to rent it out is the start of reclaiming it.
2. The brain-science mirror is striking but partial
Researchers studying experienced meditators have reported several convergent findings: the default mode network (DMN) — the neural system most active when the mind is wandering in self-referential narrative — tends to quiet down; activity in the salience and executive networks reorganizes; there are changes in autonomic regulation and even in functional connectivity. These are *neural correlates* of certain meditative states, and they suggest that the *texture* of mind can change with practice.
But — and the text itself insists on this — neural correlates are not the same as 光明寂照. The DMN is a description of a brain system; it does not have 靈源; it is not *originally unborn*; it does not pervade like the sands of the Ganges. The brain-science findings can *hint* that the kind of awareness 光明寂照 describes is a real possibility for a human being; they cannot establish its nature or its soteriological significance. Used carefully, they are a corroborating witness. Used carelessly, they collapse the teaching into a psychotechnology.
A similar caution applies to comparisons with artificial intelligence. Contemporary large models process inputs and produce outputs without the kind of awareness that 照 describes. The phrase 「剖判彰神用」 implies a *first-person* knowing that AI systems, on present understanding, do not have. Comparing 光明寂照 to "what AI does" is therefore a category error, even if some of the underlying computational metaphors (a "global workspace" in Baars's theory, a "predictive model" in Friston's free-energy framework) rhyme with certain aspects of the teaching. The rhyme is suggestive; it is not identity.
3. The longing for an unconditioned ground is more acute, not less
Modern life is, in a deep sense, *conditioned* all the way down. Even our sense of self is increasingly described as a *constructed narrative*, an integration of multiple sub-personalities, a constantly-updated prediction. For someone who has internalized this picture, the experience of being a stable, knowing self can become subtly disorienting. 光明寂照 offers something unusual within this landscape: it does not deny the constructed-ness of ordinary experience (the text is explicit that 生滅 goes on), but it points to a 靈源 that is 本不生 (originally unborn) — unconstructed, not made by any process. This is not a return to a pre-modern naïveté; it is a very precise kind of freedom *within* the conditioned. It is needed now in part because the contemporary picture makes the unconditioned harder, not easier, to talk about — and so the language that talks about it clearly is more, not less, valuable.
四、常见误读与澄清
It is worth gathering the most common ways this phrase gets bent out of shape, because most of them come from good intentions.
误读 1 — 「寂」就是发呆、走神、什么都不想
This is the most common error. People translate 寂 as "empty" or "blank" and assume the practice is to *make the mind blank*. But the text is unambiguous: 「離念性虛明」, *empty-yet-luminous*. Emptiness here is not the absence of content; it is the absence of *self-clenching about content*. The 虛 is the *space* in which things appear, not the *denial* that things appear. A blank mind that cannot perceive a sudden loud noise has lost the 照; it has not gained 寂.
A useful diagnostic: **寂 is not a state of mind. It is the *quality* of a mind that is no longer grasping at its states.** So 寂 is present in the moment you *notice* you've been thinking, just as much as in the rare moment when you notice you haven't been thinking. In fact, the latter is more characteristic.
误读 2 — 「照」就是集中注意力、就是專注
This is the meditation-world version of the same mistake. People learn 止 (śamatha, calm-abiding) and assume they have learned 照. They have not. 止 is *directing* awareness at one object; 照 is *allowing* awareness to pervade without directing. In a museum, 止 is standing in front of one painting and looking only at it; 照 is being in the room where every painting is available to be seen, without the eyes having to lock. Both have their uses; they are not the same.
误读 3 — 「光明」就是看见了神秘的光
Some meditation traditions do cultivate visualizations of light, and these can be legitimate within their own frameworks. But the 光明 of 光明寂照 is not an experience to be produced. It is the innate, ever-present *clarity-aspect* of mind. To chase it as an experience is to *外求聲* — to seek the sound outside, exactly what the text forbids. If light-experiences arise during practice, the classical Chan attitude is to notice them as phenomena — interesting, but no more sacred than the sensation of the cushion under the legs.
误读 4 — 「光明寂照」是一个要去达成的境界
This is the most subtle and most pervasive error. Contemporary readers, used to thinking in terms of *goals* and *achievements*, naturally read the phrase as a destination: "once I reach 光明寂照, I will be enlightened." The text directly refuses this. The 靈源 is *本不生*; the luminosity *already* pervades like the sands of the Ganges. There is no future moment at which it begins. The practice is therefore not *acquiring* a state but *un-obstructing* what is already the case.
This is why 離念 is the precondition and not the *content* of the practice. You are not trying to have a particular thought-free experience; you are trying to recognize the *already-present* non-clenching of awareness that is independent of any particular experience. The shift is in *recognition*, not in *experience*. Recognizing what was always the case is sometimes called, in Chan, *seeing one's nature* (見性); the texts are emphatic that nothing is added in the seeing.
误读 5 — 「不立爾汝」就是「不要分別」, 於是一切道德判斷都被取消了
This is the misreading that worries moral philosophy the most, so it is worth being careful. 「慎勿於中論爾汝」 is a description of what the luminosity itself does, not a prohibition against all discrimination. The very next passage praises 剖判 (discerning judgment) and praises 機逐淺深評 (responding to capacities with appropriate assessment). Discrimination in skillful action is *part of* 神用 and 覺明.
What the text is refusing is *the self-other split that organizes experience around an ego*. You can absolutely judge that one action is more skillful than another. What the text refuses is the *inner narrator that needs to be right against someone else's wrongness*, the courtroom drama in which your existence is stabilized by someone else's failure. Moral discernment operates perfectly well inside 光明寂照; ego-driven moral positioning does not.
误读 6 — 把它读成一种新纪元运动 (New Age 「宇宙意識」)
The contemporary marketplace is full of language about "cosmic consciousness," "oneness," "higher vibration," "awakening." Some of this vocabulary overlaps with 光明寂照 on the surface; almost none of it maps onto the classical content. 光明寂照 is not a *vibration* to be raised; it is not a *consciousness* to be expanded; it is not an *experience* to be attained. It is the *suchness* of awareness as the Buddhist tradition analyzes it — bound up with no-self, with 緣起, with the whole liberation-path, and specifically with the refusal to *外求聲*.
The practical test: if a teaching about "luminous awareness" does not also teach the dissolution of self-clinging, the deconstruction of the self-other split, the endurance of difficult truths (法忍力), and the integration of discernment (神用) — it is teaching something else, however similar the words may be.
误读 7 — 把它读成纯粹个人內觀的「我自己的經驗」
Finally, the most contemporary misreading of all: treating the phrase as a private phenomenological report. "I had this experience of luminous stillness once, on retreat." That framing locates 光明寂照 in *you-as-individual* and treats it as *your experience to possess*. The classical text is pointedly anti-individualistic: the luminosity pervades like the sands of the Ganges; within it, no 爾汝 is to be erected. The teaching is not "I had a great experience" but "this is what awareness is, all along, when it is not being obstructed." The shift is from possessive experience to *recognition of the nature of awareness as such*. That is a difference with practical, ethical, and philosophical consequences, not just a tonal one.
A final word. The 古尊宿語錄 pairs the affirmation 「光明寂照徧河沙」 with the warning 「慎勿於中論爾汝」 because the two clauses are doing different jobs that together make the teaching whole. The first clause says: *this is what awareness is, when nothing is in the way.* The second clause says: *the first way you will know something is in the way is that you start dividing the field into you and me.* Together, they describe both the ground and the most common obstacle to recognizing it. A contemporary reader who lets those two clauses work together is, perhaps, already in the middle of the practice — even if no one is sitting on a cushion and no extraordinary light has appeared. The luminosity was pervading this sentence too.
