What This Concept Is Talking About

In Buddhist meditation and cognitive analysis, Jué-Guān (覺觀, Sanskrit: *vitarka-vicāra*) refers to two foundational layers of mental activity: the initial seeking or directing of attention, and the subsequent sustained inspection or reflection.

In earlier Chinese translations of the Sutras (such as Kumārajīva’s translations and the *Saṃyukta Āgama*), these two are rendered as Jué (覺) and Guān (觀). In later scholastic re-translations (such as Xuanzang’s), they are termed Xún (尋, *vitarka*) and (伺, *vicāra*). Often, earlier texts also refer to this cognitive movement as Jué-Xiǎng (覺想, initial thought/concept formation) or Yì-Niàn Zhū Jué-Xiǎng (意念諸覺想).

To understand this concept deeply, we must avoid reducing it to a single word like "thinking" or "meditation." *Jué-Guān* forms a precise two-tiered structural pair:

1. **Jué / Xún (覺 / 尋 - *Vitarka*): Gross Mental Application / Initial Targeting.** This is the initial striking or aiming of the mind toward an object. It is coarse, energetic, and active. Classic Buddhist treatises compare *vitarka* to a bird flapping its wings to launch into the air, or the initial striking of a brass bell. It turns the mind toward a specific sensory or mental target.

2. **Guān / Cì (觀 / 伺 - *Vicāra*): Subtle Mental Sustaining / Inspection.** This is the lingering, detailed inspection and deliberation that stays with the target object once initial contact is made. It is subtle, continuous, and analytical. Treatises compare *vicāra* to the bird gliding smoothly through the air after takeoff, or the lingering resonance (*reverberation*) of the bell after it has been struck.

*Jué-Guān*’s Position in the Path of Liberation (*Vimutti-magga*)

Across classical canonical texts (such as the *Saṃyukta Āgama* [雜阿含經], *Mahāsaṃnipāta Sūtra* [大方等大集經], and *Sūtra on Unraveling the Node* [佛說解節經]), *Jué-Guān* occupies a pivotal, multi-layered position:

* **The Root of Worldly Desire and Affliction (*Kleśa*):** The *Saṃyukta Āgama* famously declares: *"Only when there is Jué-Xiǎng [conceptual thought], is there man’s desire."* (*唯有覺想者,是則士夫欲*). External sense objects (*rūpa*) themselves do not bind human beings; rather, it is the internal mental movement—the seeking, grasping, evaluating, and labeling (*Jué-Guān*)—that fuels craving (*taṇhā*), aversion (*dveṣa*), and anxiety. The texts note that afflictions depend upon *Jué-Xiǎng* just as a newborn baby depends on its mother’s milk. * The Bridge to Language and Empirical Cognition: *Jué-Guān* is the internal motor of speech. As stated in the *Mahāsaṃnipāta Sūtra*: *"If there were no Jué-Guān, how could there be speech?"* (*若無覺觀,雲何有說*). Furthermore, *Jué-Guān* relies directly on the "Four Matters" (*Sì-Shì* 四事): seeing, hearing, sensing, and knowing (*見、聞、覺、知*). It operates via comparative deduction (*Bǐ-Dù* 比度) and memory retention (*Yì-Chí* 憶持). * A Necessary Rung in Meditation That Must Be Abandoned: In the schema of the Four Dhyānas (Four Meditative Absorptions / 初禪至四禪), First Dhyāna (*初禪*) is free from unwholesome sensual desires, yet it retains five factors (*初禪五支*): *Jué* (寻), *Guān* (伺), joy born of seclusion (*離生喜*), bliss (*樂*), and one-pointedness of mind (*定*). Because *Jué-Guān* is still a subtle form of mental disturbance, the practitioner must "extinguish *Jué-Guān*" (*滅於覺觀*) to enter Second Dhyāna (*二禪*), achieving inner tranquility and noble silence (*聖默然*). * **Transcended in Ultimate Reality (*Tathātā* / 法性實相):** In ultimate truth, the true nature of reality is "beyond the realm of Jué-Guān" (*過覺觀境*). The ultimate state is non-discursive, unconditioned, and free from verbal contention (*無諍*).

The Five Metaphors of Cognitive Limitation (from *佛說解節經*)

Why can’t ordinary beings comprehend Ultimate Reality through analytical thinking (*Jué-Guān*)? The *Sūtra on Unraveling the Node* (*佛說解節經*) provides five precise structural metaphors:

1. Eating Bitter vs. Tasting Honey: Someone who has tasted only bitterness their whole life cannot conceive or deduce the sweetness of honey. 2. **Sensual Heat vs. The Joy of Seclusion (*離樂*): Someone burning in the fever of sense-desires cannot imagine the cool, internal bliss born of stepping away from sense objects. 3. Verbal Argument vs. Noble Silence (*聖默然定*): Someone obsessed with debates, arguments, and intellectual noise cannot conceive the profound stillness of meditative silence. 4. Empirical Sensing (*四事*) vs. Parinirvāṇa:** Someone who measures reality purely through sensory perception (*見聞覺知*) cannot imagine Nirvāṇa, which completely transcends sensory dependency and ego-view. 5. **Wealth/Warfare vs. Unconditioned Bliss (*無我所現法樂*):** Rulers who hoard wealth and wage war cannot comprehend the peaceful, unpossessive joy of the inhabitants of Uttarakuru (*北俱盧洲*), where "mine-ness" (*mama-kāra*) does not exist.


Walkthrough in Daily Life

To see *Jué-Guān* in action, let us trace a common modern experience step-by-step: getting an unexpected late-night email notification from your manager while relaxing at home.

``` [Phone screen lights up] ──> "Project Update Needed Urgently" │ ┌──────────────────────────────┴──────────────────────────────┐ ▼ ▼ 1. Initial Aiming (Jué / Vitarka / 尋) 2. Sustained Inspection (Guān / Vicāra / 伺) • Coarse mental strike onto the notification • Lingering analysis: "Did I mess up?" • Mind leaps from rest to alert • Simulating scenarios, drafting replies │ │ └──────────────────────────────┬──────────────────────────────┘ ▼ 3. The Birth of Proliferation (Jué-Xiǎng / Papañca) • "My job security is threatened!" ──> Anxiety / Defensive Anger (Kleśa) ```

Step-by-Step Mapping:

1. **The Initial Aiming (*Jué* / *Vitarka* / 尋):** * What happens: Your phone screen lights up with a vibration. Your mind abruptly turns, leaps toward the red banner, and locks onto the subject line: *"Urgent: Client Presentation Revision."* * Exact classical definition: This is the coarse, sudden application of attention (*Jué*). It is the bird flapping its wings to jump off the branch, or the hammer striking the bell.

2. **The Sustained Inspection (*Guān* / *Vicāra* / 伺):** * What happens: Having focused on the subject line, your mind stays locked onto it, probing deeper: *"Why is he emailing at 9:30 PM? Is the client unhappy? Did I miss a calculation in slide 4?"* You begin mentally replaying conversations from earlier today and drafting potential arguments. * Exact classical definition: This is the sustained, detailed investigation (*Guān*). It is the bird gliding through the wind, or the sound vibrating and echoing in the bell.

3. **Grasping and Affliction (*Jué-Xiǎng* / 覺想):** * What happens: As *Jué* and *Guān* feed each other, conceptual proliferation (*papañca*) kicks in. You start projecting future scenarios: *"If I get fired, I can't pay the mortgage."* Tightness fills your chest, heartbeat accelerates, and resentment arises toward your boss. * Canonical connection: As the *Saṃyukta Āgama* states, the physical notification (the visual *rūpa*) is not the actual source of your suffering; your internal *Jué-Xiǎng* is the mother that feeds the newborn child of anxiety.

Common Mapping Errors in Modern Mindset:

* **Error 1: Mapping *Jué-Guān* only to formal sitting meditation.** *Correction:* *Jué-Guān* happens hundreds of times a day—every time you swipe on social media, hear a loud noise, or jump into an argument in a work group chat. * **Error 2: Mistaking *Jué* for "Spiritual Awareness / Awakening" (Translational Confusion).** *Correction:* In modern Chinese, *Jué* (覺) often means "enlightenment" or "awareness" (as in *Jué-Wù* 覺悟). But in classical early translations of *Jué-Guān*, *Jué* translates *vitarka*—a discursive, gross mental searching that must eventually be stilled, not worshipped as ultimate wisdom.


Why Contemporary People Need It

Modern society is an unprecedented "Jué-Guān Hyper-Stimulation Engine."

Every smartphone app, algorithmic push notification, and short-video feed is engineered to hijack your *Jué* (grabbing your initial coarse attention) and loop your *Guān* (keeping you scrolling, judging, comparing, and inspecting details).

``` Algorithmic Hook (Ding!) ──> Triggers Jué (尋) ──> Loops Guān (伺) ──> Mental Exhaustion ```

1. Understanding Mental Burnout: Cognitive fatigue in the modern workplace is rarely just muscle tiredness; it is the exhaustion of unceasing *Jué-Guān*. When you switch tabs 50 times an hour, check messages during dinner, and re-read stressful emails in bed, your mind remains stuck in high-frequency *vitarka-vicāra*. 2. **The Key to Meditative Depth (Breath Meditation / *Ānāpānasati*): Classical texts repeatedly highlight Ānāpānasati** (mindfulness of breathing / 出入息念 / 安那般那念) as the direct antidote to *Jué-Guān*. * When practicing breath counting (*数息*), counting the breath helps break unwholesome *Jué-Guān* (*離惡覺觀*). * As stability deepens, the mind drops the gross searching (*Jué*) and subtle probing (*Guān*), settling into natural quietude—a state where mental energy stops leaking into endless narrative construction. 3. Contemporary Analogies (And Their Scientific Boundaries): * AI / Computational Analogy: *Jué* is like an search query initiated by an algorithm (fetching candidate data), while *Guān* is the deep neural network processing those details. Ultimate reality (*Tathātā*) would be like the underlying hardware physics—completely beyond the software’s internal symbols and logic. * Neuroscience Analogy: Neuroscientists study the Default Mode Network (DMN), which lights up during self-referential thought, future planning, and rumination, contrasting with task-positive or resting networks. * Crucial Distinction & Limitation: While neuroscience maps brain blood flow and electrical signals associated with cognitive states, science examines third-person physical correlates. Buddhist *Jué-Guān* analysis is a first-person phenomenology designed for radical ethical transformation and liberation from suffering (*mokṣa*). Neuroscience does not "prove" Dharma, nor can brain scans replace the internal, self-realized cessation of conceptual grasping (*過覺觀境*).


Common Misunderstandings and Clarifications

1. "Is *Jué-Guān* entirely evil or bad? Should we eliminate all thinking immediately?"

Clarification: No. In the Buddhist path, *Jué-Guān* is a functional mental factor (*Caitasika*). * In daily life and early stages of practice, one uses wholesome Jué-Guān (*善覺觀*)—such as contemplating impermanence, reflecting on karma, or practicing mindfulness—to abandon unwholesome Jué-Guān (*惡覺觀*, such as lust, ill-will, or cruelty). * Even in First Dhyāna (*初禪*), *Jué* and *Guān* are necessary factors that allow the mind to stay anchored on the meditation object while abandoning gross sensual desire. It is only when advancing toward Second Dhyāna (*二禪*) and ultimate liberation that *Jué-Guān* is recognized as a subtle turbulence and left behind.

2. "If Ultimate Reality is beyond *Jué-Guān* (*過覺觀境*), can we reach enlightenment by logical reasoning and philosophical debate?"

Clarification: Logical reasoning (*Bǐ-Dù* 比度) and conceptual retention (*Yì-Chí* 憶持) belong entirely to the domain of *Jué-Guān*. As the *Sūtra on Unraveling the Node* (*佛說解節經*) points out, using conceptual thinking to figure out ultimate truth is like a person who has eaten bitter food all their life trying to "think out" the taste of honey. Conceptual thought can point toward the door (as conventional truth / *Saṃvṛti-satya*), but entering the room (ultimate truth / *Paramārtha-satya*) requires direct, non-conceptual personal realization (*自證無相法*), where speech ends and *Jué-Guān* naturally stills.

3. "Does extinguishing *Jué-Guān* mean becoming like a stone or a piece of wood?"

Clarification: Absolutely not. Extinguishing *Jué-Guān* (*滅於覺觀*) does not mean falling into unconsciousness or blank stupor. It means transitioning from discursive, grasping cognitive agitation to luminous, unshakeable awareness. When the turbulent waves of *Jué-Guān* subside, the underlying clarity of the mind shines forth—free from ego-centered narrative, arguments (*無諍*), and afflictive noise.

Canonical EntryAI-generated

一、 定义与核心要义

「觉观」(梵语:vitarka-vicāra)在佛教经典中,主要指禅定修行中的「寻」与「伺」等心识攀缘、思惟与取舍活动。在凡夫境界中,觉观是欲望与烦恼的根源与依凭,与言语宣说、见闻觉知等紧密相连;在禅修实践中,它是修行者需要逐步收摄、对治并最终舍离的对象;而在终极的法性实相(真实)层面,则是彻底超越一切觉观境界的。

二、 主要阐述

综合各部类经典,对「觉观」的论述主要展开为以下几个维度:

第一,觉观与欲望、烦恼的依寄关系。经典指出,世间的色境本身并非束缚,内心的「觉想」才是真正的欲望(「唯有觉想者,是则士夫欲」)。觉想与贪心、恚心、恐怖等负面身心反应皆有所因、有所依,其依寄关系犹如新生儿依倚乳母。同时,众生在「觉观未尽」时,会在身心中处处产生攀缘与取舍,进而生起种种有法与生灭增长。

第二,禅修中对觉观的对治、断除与息灭。在禅修实践中,修行者需如「龟藏六」般,将心识收摄,密藏诸觉想,以防范外界侵害并达到无所依的状态。具体修行路径上,修习「安那般那念」(出入息念)是断除诸觉想的重要方法,能使心不为所动,证得大果;在数息法中,修数息可离恶觉观,修随顺可离善觉观,通过「数增」能坏一切觉观。在禅定阶位中,初禅虽离欲界恶法,但仍具备「有觉有观」的特征(初禅五支包含觉与观),修行者必须进一步「灭于觉观」才能证入第二禅。若能使一切心相觉观想灭,或舍离一切乱想觉观,便能口离语言,入寂灭三昧。此外,在特定禅修层次中,修行者甚至能不依地水火风乃至觉观而修禅定,达到极为高深的境界。

第三,实相境界对觉观的彻底超越。经典强调,诸法实相是「过觉观境」的,终极的「至处」亦是「非觉非观」的真实之性。佛陀将「真实」与「觉观」进行了对比:真实是圣人自证、无相、不可言说、断绝见闻觉知(四事)且无诤的;而觉观则是凡夫共境、缘相、依赖言说、攀缘四事且属于斗诤境界的。凡夫因身处觉观境界,无法去思量、比度或忆持那超越觉观的实样,正如一生吃苦的人无法想像蜜的甜味,沉溺欲尘者无法想像离欲之乐,喜好言诤者无法想像圣默然定,耽着四事者无法想像般涅槃,蓄财征伐者无法想像北俱卢洲的无我所现法乐一样。

三、 不同部类与译本的表述差异

在不同部类及译本中,「觉观」及相关概念的术语呈现出明显的差异: - 在《杂阿含经》(《雜阿含經》)中,最常用的术语是「觉想」,有时表述为「意念诸觉想」,而在特定问答中则直接使用「觉观」。 - 在《大方等大集经》(《大方等大集經》)中,将初禅五支中的寻、伺直接译为「觉」与「观」;该经在其他术语上亦有独特表述,如以「五阴」称呼「五蕴」,并将数息法译为「阿那波那」,解释为「入名阿那,出名波那」。 - 在《佛说解节经》(《佛說解節經》)中,将昙无竭菩萨译为「法上」;将见、闻、觉、知统称为「四事」;并将与觉观并列的认知活动表述为「比度」与「忆持」。

四、 与相关概念的关系

- 与言语(言说)的关系:觉观与言语直接相关。若无觉观则无从宣说,修行者唯有「舍觉观故口离语言」;而真实实相则是「离言」且「过诸觉观境」的。 - 与见闻觉知(四事)的关系:觉观是「缘四事行处」,即攀缘见、闻、觉、知而生起;而真实实相则是「绝四事」的,彻底灭离了身见与四事。 - 与智慧(尽智、无生智)的关系:觉观的息灭与解脱智直接关联,经中指出「不觉观烦恼名曰尽智,不觉观果报名无生智」。 - 与安那般那念(数息)的关系:安那般那念是治罚与断除觉观的关键法门,修习数息能「坏一切觉观」。

五、 代表性原文引用

- 《杂阿含经》:「唯有觉想者,是则士夫欲。」;「比丘修禅思,善摄诸觉想。」 - 《大方等大集经》:「若无觉观,云何有说。」;「不觉观烦恼名曰尽智,不觉观果报名无生智。」;「舍觉观故口离语言。」 - 《佛说解节经》:「自证无相法,离言绝四事,无诤法通相,过诸觉观境。」

雜阿含經T0099 · 阿含部

《雜阿含經》論及「覺觀」這一概念時,絕大多數場合所用術語實為「覺想」,而非後世論書常見的「覺觀」二字。全經僅一處明確出現「覺觀」:跋迦利尊者問佛,比丘如何入禪而「不依地、水、火、風,乃至覺觀,而修禪定」,此處覺觀與四大並舉,屬禪定所不依恃的對象。除此之外,經中一律以「覺想」稱之,此即本經獨特的用語形式,為多譯名歸一所當記錄。

就覺想之性質而言,本經將之與欲貪緊密聯繫。經云:「非彼愛欲使,世間種種色,唯有覺想者,是則士夫欲」,意謂世間色境本身並非欲貪之根,真正令人生欲的是覺想——即內心對所緣的分別構畫。欲不在外境而在覺想,調伏覺想方為黠慧者所行。此處覺想被定位為「士夫欲」的直接成因,是本經論覺想最核心的命題。

就對治覺想之修行而言,本經提出兩條路徑。其一為攝心守護:以龜藏六於殼為喻,「比丘習禪思,善攝諸覺想,其心無所依,他莫能恐怖」;另一偈重申此喻:「比丘善攝心,密藏諸覺想。不依不怖彼,覆心勿言說」。兩偈皆以龜殼喻禪思之防護,強調覺想須如龜之六根般密藏收攝,令心無所依傍、不為外境所恐怖。其二為安那般那念(入出息念):佛告諸比丘「當修安那般那念。安那般那念修習多修習者,斷諸覺想」,並謂由此能得不動搖、大果大福利、甘露、究竟甘露,乃至二果、四果、七果。此處覺想非僅被攝伏,而是被「斷」,語氣較「善攝」更為徹底。

就覺想之生起因緣而言,本經以問難形式追問其源頭:「貪恚何所因,不樂身毛竪,恐怖從何起,覺想由何生?猶如鳩摩羅,依倚於乳母」;另一偈重述:「意念諸覺想,為從何所起,猶如新生兒,依倚於乳母」。兩偈以嬰兒依乳母為喻,暗示覺想有所依恃而生,與貪恚、恐怖同屬有因有緣之法,非無端而起。此處「覺想」與「意念」連用(「意念諸覺想」),顯示本經將覺想視為意念活動的一種形態。

綜觀本經,覺想(僅一處作覺觀)被視為禪定中須攝伏乃至斷除的內心分別作用,是欲貪的真正根源而非外境本身;對治之道在善攝與安那般那念之斷除;其生起則如嬰兒依乳母,有所依因而起。術語上,本經以「覺想」為常例、「覺觀」為孤例,與阿毘達磨系統以「覺」「觀」分列粗細二用之慣例有別。

大方等大集經T0397 · 大集部

《大方等大集經》論「覺觀」,貫通般若無說、禪觀實修與唯心見佛三個層面,用語始終作「覺觀」,未見「尋伺」「覺察」等異稱。

一、覺觀與法性無說。無言菩薩答諸菩薩問「住何地能如是答」,謂住法性實相法界而答,「若如是知法真實者,則無覺觀。若無覺觀,云何有說?」 覺觀在此是言說之所以成立的粗細審察作用;證入法性真實則覺觀自息,既無覺觀即無言說可立。同段復云一切法義「無有覺觀,猶如響相,如佛化故」,將覺觀之闕如與響、化同喻,強調諸法不可宣說。淨德優婆塞亦以「無覺觀故,云何而言能調眾生」詰問明星菩薩,把覺觀視為教化施設之前提;而所問「至處」之真實性則「非覺非觀,非有非無,非行非生,非出非滅」,以遮詮方式將覺觀排除於究竟實性之外。

二、覺觀與數息禪修。佛告憍陳如,法行比丘「滅覺觀心境界都息,永離煩惱其心寂靜」,方能隨願得聲聞、緣覺、如來菩提。修數息(阿那波那)時獲得二事:「一者、離惡覺觀;二者、觀息相貌」。此處覺觀帶有善惡分判——「惡覺觀」為所離對象,與觀息之善所緣對舉。同段以「不覺觀煩惱名曰盡智,不覺觀果報名無生智」,將「不覺觀」用作盡智、無生智的界定語,意謂不再以粗細審察攀緣煩惱及其果報,即是二智之體。

三、覺觀為諸法生起之因緣。行者見無量佛時自念:「我隨覺觀,欲多見多欲少見少」「我因覺觀見無量佛」「一切諸法皆從覺觀因緣而生」。此段將覺觀提升為萬法顯現的生成條件:所見佛之多少、大小、色相皆隨覺觀而轉,法性即是虛空,覺觀因緣生一切法。緊接其後,不共凡夫四諦順陀羅尼的修法則是反向操作:知虛空「無有覺觀不可宣說」,心亦如是,遂「捨離是空色等一切諸念亂想覺觀」,捨覺觀故口離語言,心安一緣修習滅定,終入寂滅三昧。覺觀在此既是流轉之因,亦是還滅所捨。

四、覺觀未盡則有法增長。佛言「若一切眾生覺觀未盡,如是時中一切有法大瘡大莿種種有生」,覺觀未斷則三界有法相續增長。行者觀「處處覺觀攀緣取捨」,知身心因緣和合而生,進而修「一切心相覺觀想滅寂靜心住」,以覺觀想之滅為寂滅方便。此處「覺觀想滅」連用,顯示覺觀與想(saṃjñā)在止觀操作中的密切關聯。

總之,本經以「覺觀」一詞統攝粗細審察義,既在般若脈絡中視之為言說與教化之前設、證真實時自然息滅;又在禪修脈絡中視為數息所離之惡法、滅定所捨之亂想;更在唯心見佛脈絡中視為萬法顯現之因緣,形成「由覺觀生→捨覺觀滅」的完整修證弧線。

深密解脫經T0675 · 經集部

《深密解脫經》(元魏菩提流支譯)對「覺觀」一概念的論述,集中於將覺觀定位為障蔽第一義的分別活動,並與「離言」「寂滅」對舉,呈現出否定性的修證取向。

一、覺觀作為五重障蔽之一。經中佛告曇無竭,以「長夜」為喻,層層列出五類眾生各有所溺而不能信解更高境界:信貪欲樂者不能信離色聲香味觸之無貪欲樂;樂分別者不能信內身寂靜無分別樂;樂見聞覺知者不能信內身寂滅離見聞覺知樂;取我我相者不能信北欝單越無我我所樂;最後,「如是覺觀之人,不能知、不能覺、不能量、不能信離諸覺觀第一義相」。覺觀在此並非孤立的禪定術語,而是與貪欲、分別、見聞覺知、我執並列為五種「長夜」習氣,其共同結構為:溺於某一層次的活動,即無法信解超越該層次的寂靜境界。覺觀所障蔽的對象,經文明言是「離諸覺觀第一義相」,亦即覺觀之對治目標並非另一種覺觀,而是徹底離卻覺觀後所顯的第一義。

二、覺觀與「諍相」連稱。世尊偈頌云:「我說身證法,第一離言境,離覺觀諍相,無言第一義。」 此處「覺觀」與「諍相」合為一詞組「覺觀諍相」,表明本經將覺觀理解為帶有諍論、對立性質的心行——覺觀即是內心對所緣的粗細審察與分別,而此分別本身構成諍相,與「無言第一義」直接對反。偈頌以「離言」與「無言」前後呼應,將覺觀諍相歸入言說分別的範疇,所證之法則是「身證」「離言」,非覺觀所能觸及。

三、本經用語特徵。本經直接使用「覺觀」一詞,未以「尋伺」或其他譯名替代;與覺觀對舉的境界,經中稱為「第一義相」「第一離言境」「無言第一義」,而不用「真如」「法性」等名。此外,本經以「不能知、不能覺、不能量、不能信」四重否定句式描述覺觀之人的認知封閉狀態,其中「不能量」一語頗具特色,暗示覺觀所障者包含對離覺觀境的「量度」——即比量推度亦不能及,非僅信解不足而已。

四、覺觀在本經中的定位。綜合兩段原文,本經並未正面界定覺觀為禪定中粗細審察所緣的作用,而是從反面——從「覺觀之人」的不能信解、從「離覺觀諍相」的偈頌——將覺觀標定為必須超越的分別層次。覺觀不是被分析的禪支,而是被否定的障道因;其對立面不是「無覺有觀」或「無覺無觀」的禪定階次,而是「身證」「離言」「無言」的第一義境。這是本經論述覺觀的獨特側重:不在禪定階次內定位覺觀,而在證悟論的框架中將覺觀整體歸入言說分別,與第一義對舉而否定之。
