What This Concept Means

In the Buddhist liberation path, Unwise Attention (*ayoniśo manasikāra* / 不正思惟) is not merely a momentary lapse in concentration or an occasional negative thought. It is the fundamental, underlying cognitive malfunction that fuels the entire cycle of suffering (*saṃsāra*).

Etymologically, *yoni* means "womb," "origin," or "root," and *manasikāra* means "mental engagement" or "bringing to mind." Thus, *ayoniśo manasikāra* refers to a way of attending to reality that is ungrounded in its true origins—an improper, distorted direction of attention that misinterprets the nature of phenomena.

In early Buddhist discourses, such as the *Madhyama Āgama* (《中阿含經》) and the *Saṃyukta Āgama* (《雜阿含經》), Wise Attention (*yoniśo manasikāra* / 正思惟 or 正作意) and Unwise Attention (*ayoniśo manasikāra* / 不正思惟) are identified as the single most decisive pivot determining whether an individual generates mental defilements (*āsava* / 漏) or achieves liberation (*vimukti* / 解脫).

To fully understand *ayoniśo manasikāra*, we must examine its distinct canonical facets across four key dimensions:

1. "Thinking What Should Not Be Thought, and Neglecting What Should Be Thought"

In the *Madhyama Āgama*, Unwise Attention is described as the state where a person "thinks about things that ought not to be thought about, and fails to think about things that ought to be thought about" (不應念法而念,應念法而不念). * What Ought Not to Be Thought: Unproductive, self-referential existential rumination regarding the past, present, and future self—such as "Did I exist in the past? Do I not exist? What was I in the past? Will I exist in the future? What am I right now?" * The Resulting Trap—The Six Views of Self (六見): Such obsessive rumination entangles the mind in six rigid identity views concerning the "soul" or "self" (神, *ātman*): 1. *Truly believing there is a self* (真有神). 2. *Truly believing there is no self* (真無神). 3. *Perceiving self with self* (神見神). 4. *Perceiving non-self with self* (神見非神). 5. *Perceiving self with non-self* (非神見神). 6. *Holding that this self is permanent, able to speak, feel, and act* (此是神,能語、能知、能作). The sutta characterizes these rigid views as "fetters of views" (見結) and "flaws of views" (見之弊), which tie uninstructed ordinary people (凡夫) to birth, aging, illness, and death. * What Ought to Be Thought: Direct, objective observation of the Four Noble Truths (*catur-āryasatya* / 四聖諦), impermanence (*anicca* / 無常), suffering (*dukkha* / 苦), and non-self (*anattā* / 無我). When attention ignores these realities and obsesses over identity, unarisen cankers—sensual defilement (*kāmāsava* / 欲漏), existence defilement (*bhavāsava* / 有漏), and ignorance defilement (*avijjāsava* / 無明漏)—arise, and existing ones proliferate.

2. Cognitive Distortion at the Sense Gates: "Viewing as Pure" and "Grasping Signs"

When sense organs interact with external objects, Unwise Attention distorts perception right at the threshold. * Viewing as Pure (淨觀): In the *Madhyama Āgama*, failing to guard the eye and mind bases stems directly from "unwise attention via viewing as pure" (不正思惟以淨觀也). This means projecting beauty, permanence, or intrinsic desirability onto conditioned, impermanent phenomena that are inherently unstable and composite. * Grasping Signs and Secondary Features (取色相): In the *Saṃyukta Āgama*, when an uncollected mind encounters sensory stimuli, Unwise Attention instantly seizes upon attractive signs (*nimitta* / 相) and details (*anubyañjana* / 隨相). This instantly kindles the fires of craving (*rāga* / 貪欲), scorching the heart and causing moral regression or loss of spiritual focus.

3. The Causal Nexus: The Origin and Downstream Effects of Unwise Attention

The suttas detail the causal chain (*āhāra* / 食, nutriment or condition) feeding into and flowing from Unwise Attention: * What Feeds Unwise Attention: Associating with bad companions (惡人) $\rightarrow$ Close contact with unwholesome guides (親近惡知識) $\rightarrow$ Listening to false/harmful teachings (聞惡法) $\rightarrow$ Lack of conviction/faith (不信) $\rightarrow$ Unwise Attention (不正思惟). * What Unwise Attention Feeds: Unwise Attention $\rightarrow$ Unwise mindfulness and unwatchful comprehension (不正念、不正智) $\rightarrow$ Lack of sense-restraint (不護諸根) $\rightarrow$ Three unwholesome bodily/verbal/mental actions (三惡行) $\rightarrow$ Five Hindrances (五蓋) $\rightarrow$ Ignorance (無明) $\rightarrow$ Craving for existence (有愛).

In the *Saṃyukta Āgama*, Unwise Attention is explicitly placed at the root of ignorance (*avijjā* / 無明). Contact between sense organ and object sparks Unwise Attention, which directly gives birth to delusion/ignorance (癡/無明), leading to craving (愛), kamma (業), and continued cyclic rebirth.

4. Disruption of Spiritual Development: Fueling Hindrances, Destroying Awakening

The *Saṃyukta Āgama* notes that among internal factors, no single phenomenon possesses as powerful a destructive force as Unwise Attention: * Inviting the Five Hindrances (五蓋): Unwise Attention causes unarisen Hindrances—sensual desire (*kāmachanda* / 貪欲蓋), ill will (*byāpāda* / 瞋恚蓋), sloth & torpor (*thīna-middha* / 睡眠蓋), restlessness & worry (*uddhacca-kukkucca* / 掉悔蓋), and doubt (*vicikicchā* / 疑蓋)—to spring up, and existing ones to multiply. * Suppressing the Seven Factors of Awakening (七覺支 / 七覺分): It prevents the birth of mindfulness (*sati*), investigation of phenomena (*dhamma-vicaya*), energy (*viriya*), joy (*pīti*), tranquility (*passaddhi*), concentration (*samādhi*), and equanimity (*upekkhā*), or causes existing ones to wither away. * Constructing the Eightfold Wrong Path (八邪): It fosters wrong view (*micchā-diṭṭhi* / 邪見) through wrong concentration (*micchā-samādhi* / 邪定), while completely dismantling the Noble Eightfold Path (八正道). * Interfering with Meditation: Even when a meditator retreats to a quiet forest for absorption, Unwise Attention can slip in, triggering restless applied and sustained thought (*vitakka-vicāra* / 覺觀) that shatters meditative composure (*samādhi* / 正受).


A Walkthrough in Daily Life

To see how *ayoniśo manasikāra* operates in contemporary life, let us walk through common daily scenarios step by step, explicitly mapping them to the classical definitions while highlighting where people usually misidentify their mental processes.

``` [ Modern Experience Walkthrough ] │ ┌───────────────────────────┼───────────────────────────┐ ▼ ▼ ▼ 1. Social Media 2. Workplace Stress 3. Relationship & Consumerism & Comparison Conflict (淨觀 / 取色相) (應念不念 / 見之弊) (五蓋 & 覺觀) ```

Scenario 1: Scrolling Social Media & Online Shopping

* The Scene: You are scrolling through a social feed during your evening commute. You see curated photos of influencers on luxury vacations, sleek digital gadgets, or ideal physiques. * The Classical Process: 1. *Eye meets form* (眼色緣): Visual contact occurs with the smartphone screen. 2. *Unwise Attention via "Viewing as Pure"* (不正思惟以淨觀也 / 取色相): The mind immediately isolates the highlighted, filtered image, attributing inherent perfection, lasting satisfaction, and glamour to it while ignoring the unshown context (debt, anxiety, filters, impermanence). 3. *Fueling Craving and Delusion* (生癡、生愛): The thought arises: *"If I purchase this or live like that, I will be complete."* 4. *Inviting the Five Hindrances*: Sensual desire (*kāmachanda*) surges, followed by restlessness (*uddhacca*) and envy. * Common Mismapping: Most people believe their suffering comes from "not having enough money to buy that item" or "algorithm-induced addiction." In truth, the canonical root is *ayoniśo manasikāra*—the mind's spontaneous decision to frame an impermanent, composite phenomenon as "pure, desirable, and self-fulfilling."

Scenario 2: Overtime, Workplace Anxiety, and Identity Crisis

* The Scene: Sitting late at your office desk after an intense performance review, you begin ruminating: *"Why did my manager say that? Am I a failure? Will I be laid off in two years? What is my worth in this industry?"* * The Classical Process: 1. *Thinking What Should Not Be Thought* (不應念法而念): Instead of observing the physical sensation of fatigue or analyzing the objective feedback (which would be *yoniśo manasikāra* / Wise Attention), the mind plunges into past regrets and future dread regarding "me." 2. *Falling into the Flaws of Views* (見之弊 / 六見): You become trapped in self-referential identity claims—*"I am fundamentally inadequate"* (真無神/邪見) or *"I must build an indestructible personal brand that endures"* (持我為常/此是神). 3. *Nourishing Ignorance and the Cankers*: Existence-canker (*bhavāsava*) and ignorance-canker (*avijjāsava*) deepen. * Common Mismapping: People often mislabel this as "healthy self-reflection" or "strategic career planning." However, early Buddhism draws a sharp line: ruminating on an imagined, enduring "I" across time is an unproductive trap (*ayoniśo manasikāra*) that amplifies anxiety, whereas examining feelings and thoughts as impermanent, conditioned phenomena (*dhamma*) is true Wise Attention.

Scenario 3: Relationship Friction and Late-Night Rumination

* The Scene: After a minor argument with your partner over domestic chores, you lie in bed trying to relax or meditate, but your mind loops endlessly: *"They always treat me like this! They don't respect me!"* * The Classical Process: 1. *Unwise Attention Triggering Applied/Sustained Thought* (不正思惟生覺觀): Even in a quiet room intended for rest or meditation (*正受*), *ayoniśo manasikāra* seizes upon a single negative memory. 2. *Procreative Hindrances*: Ill will (*byāpāda*) and restlessness (*uddhacca-kukkucca*) are actively fed and magnified. 3. *Suppressing Awakening Factors*: Tranquility (*passaddhi*) and equanimity (*upekkhā*) vanish completely. * Common Mismapping: People think, *"I am just trying to resolve the argument in my head."* Canonical wisdom reveals that framing the event around personal offense and fixed blame is *ayoniśo manasikāra*, which guarantees emotional burn and prevents genuine resolution.


Why Contemporary People Need It

Contemporary life can be understood as an unprecedented infrastructure built to exploit Unwise Attention.

``` [ Contemporary Exploitation Mechanisms ] ├── Algorithmic Feeds ──> Prompts "Viewing as Pure" (淨觀) & Sign-Grasping (取色相) ├── Personalization ──> Amplifies Existential Self-Rumination (不應念而念) └── Information Glut ──> Starves Wise Attention (正思惟) & Nourishes Hindrances (五蓋) ```

1. Algorithms as Amplifiers of "Viewing as Pure" (淨觀): Modern recommendation systems (social media, short videos, targeted ads) are precisely engineered to capture attention by serving hyper-filtered "pure/desirable signs" (*subha-nimitta*). They train the mind to engage in *ayoniśo manasikāra* hundreds of times a day, keeping dopamine loops engaged by feeding instant desire and comparison. 2. AI, Cognitive Offloading, and "False Knowledge": Generative AI and vast search tools provide instant answers, but they can easily feed what the suttas call "listening to harmful/false discourse" (聞惡法) if consumed uncritically. When information overload replaces deep inward contemplation (*yoniśo manasikāra*), people mistake accumulated data for actual wisdom, remaining bound to wrong views (*micchā-diṭṭhi*). 3. The Neuroscientific Parallel and Its Limitations: Modern neuroscience describes default mode network (DMN) hyperactivity during self-referential rumination, as well as dopamine-driven reward loops during sensory stimuli. * *Comparison*: Neuroscience confirms that unguided internal chatter and rapid sensory switching elevate stress and anxiety. * *Crucial Limitation*: Neuroscience frames these mechanisms primarily in terms of brain chemistry, cognitive bias, or evolutionary adaptation, seeking stress reduction or optimized productivity. Canonical Buddhist wisdom goes much deeper: *ayoniśo manasikāra* is an ethical and spiritual choice of mental orientation that constructs the illusion of a solid self, driving the entirety of existential suffering and cyclic rebirth. Science may map the brain's hardware, but Buddhism provides the ultimate exit strategy from the software of existential delusion.

By understanding *ayoniśo manasikāra*, contemporary individuals gain a precise mental diagnostic tool. Instead of blaming external algorithms, job pressures, or partners, one can immediately catch the internal pivot: *"Attention has just framed this object unwisely. I am taking the impermanent to be permanent, the painful to be pleasurable, or non-self to be a self."*


Common Misunderstandings and Clarifications

To prevent conceptual distortion, we must address several widespread misconceptions regarding Unwise Attention:

| Misconception | Classical Canonical Reality | | :--- | :--- | | 1. "Unwise Attention just means having negative or evil thoughts." | False. *Ayoniśo manasikāra* is not merely the *content* of a thought (like anger or lust), but the underlying mode of cognitive framing. Even seemingly "positive" thoughts—such as daydreaming about doing good deeds to build a grand, permanent legacy for "myself"—can be deeply rooted in *ayoniśo manasikāra* if grounded in identity obsession and permanence. | | 2. "Planning for your future self or reflecting on past lessons is Unwise Attention." | False. Functional, pragmatic planning grounded in impermanence and cause-and-effect (*kamma-vipāka*) is an aspect of Wise Attention (*yoniśo manasikāra*). Unwise Attention specifically refers to existential rumination (*"Who was I? What will become of ME?"*) that gives rise to the six views of self (六見). | | 3. "Unwise Attention can be cured simply by forced suppression of thought." | False. In the *Saṃyukta Āgama*, suppressing thoughts without changing the underlying mode of attention fails. Unwise Attention must be replaced by Wise Attention (*yoniśo manasikāra*)—contemplating impermanence, non-self, suffering, and the Four Noble Truths, while nourishing conviction (*saddhā* / 信), moral discipline (*sīla* / 戒), and spiritual friendship (*kalyāṇamittatā* / 親近善知識). | | 4. "Unwise Attention is caused entirely by external bad environments." | Partially inaccurate. While the sutta's causal chain lists bad companions (*惡人*) and harmful teachings (*聞惡法*) as upstream nutriments (*食*), *ayoniśo manasikāra* itself occurs in the internal mental realm (內法). As the *Saṃyukta Āgama* notes, even sitting alone in a quiet forest during meditation, an unwatchful mind can generate *ayoniśo manasikāra*. Environmental factors are external conditions; the ultimate responsibility rests on the mind's internal orientation. |


Summary: The Ultimate Pivot on the Path to Liberation

In the architecture of Buddhist practice, Unwise Attention (*ayoniśo manasikāra*) is the master switch of suffering, while Wise Attention (*yoniśo manasikāra*) is the master switch of freedom.

When attention is directed unwisely, every sensory encounter nourishes delusion, fuels the Five Hindrances, builds the Eightfold Wrong Path, and solidifies the prison of selfhood. But the moment attention is turned inward to observe phenomena as they truly are—conditioned, transient, and devoid of an enduring core—the chain of ignorance breaks. By recognizing *ayoniśo manasikāra* in the midst of daily noise, scrolling, and stress, a practitioner transforms everyday awareness into the ground of awakening.

Canonical EntryAI-generated

一、定义与核心要义

「不正思惟」(ayoniśo manasikāra)是佛学中的核心概念,指导致烦恼增长、障碍善法与解脱修行的错误认知与思考方式。

在《中阿含经》(《中阿含經》)中,不正思惟被视为决定修行者能否漏尽的关键因素。凡夫愚人因未能听闻正法、不值真知识,不知且不调御圣法,因而产生不正思惟,导致「不应念法而念,应念法而不念」,进而使未生的「欲漏」、「有漏」、「无明漏」得以产生,已生的漏则增长广大。

在《杂阿含经》(《雜阿含經》)中,不正思惟被阐述为一切恶不善法生起与增长的根本关键。经中强调,在「内法」中,没有任何一个法能像「不正思惟」那样具有如此强大的负面力量。它是无明生起的因与缘,也是障碍修行、退失善法的核心逆缘。

二、主要阐述

1. 认知偏差与对「自我」的邪见

根据《中阿含经》的论述,不正思惟具体表现为对过去、未来及现在自我的无益思忖与怀疑。例如,修行者会思维「我有过去世,我无过去世……我何因过去世……」以及「我有未来世……自疑己身何谓是……」等。这种不正思惟会直接引发关于「神」(即灵魂、自我)的六种邪见(六见),包括「真有神」、「真无神」、「神见神」、「神见非神」、「非神见神」以及「此是神,能语、能知、能作……」等。这些邪见被称为「见之弊」,使凡夫被见结所系,无法脱离生老病死之苦。

2. 感官防护中的失控与「净观」

在感官防护(根律仪)的实践中,不正思惟扮演了关键的破坏性角色。 《中阿含经》指出,「不护眼根」与「不护意根」的根源在于「不正思惟以净观也」。此处的「净观」是指将事物视为清净、美好的错误观察方式,这是不正思惟在面对色、声、香、味、触、法时的具体运作,会直接导致烦恼与忧戚的产生。 《杂阿含经》则进一步指出,若修行者不善护身、不守根门、心不系念,在面对外境(如见诸女人)时,就会起「不正思惟」而「取色相」,进而引发炽燃的贪欲,烧灼身心,甚至导致舍戒退减。相反,若能善于护心,即使身处娱乐与女色之中,亦能做到「无一刹那不正思惟」。

3. 禅修中的觉观干扰

在禅修实践中,不正思惟同样会带来干扰。根据《杂阿含经》,修行者即使在林中禅修(入昼正受)时,仍可能起「不正思惟」,此时会被「觉观」(寻伺)所困扰。经中指出,此时应当「舍不正念,专修于正受」,通过皈依三宝、持净戒与生随喜心来克服不正思惟的干扰。

4. 助长恶法与退失善法

《杂阿含经》详细论述了不正思惟对修行心态的决定性负面影响: - 助长五盖、退失觉支:不正思惟会使未生起的「贪欲盖、瞋恚盖、睡眠盖、掉悔盖、疑盖」生起,已生起者则重生并增广;同时,它会使未生起的「念、择法、精进、喜、猗、定、舍」等「七觉支」(或称「七觉分」)无法生起,已生起者则退失。 - 生起八邪、退失八正:不正思惟会令未生起的「邪见、邪志、邪语、邪业、邪命、邪方便、邪念、邪定」等八邪法生起并增广;相反地,它会使未生起的「正见」等「八正道」善法无法生起,已生起者则退失。

三、不同部类与译本的表述差异

在不同经典中,对于不正思惟及其相关概念的表述存在独特的译语特征: 1. 关于「自我/灵魂」的称呼:《中阿含经》在论述不正思惟引发的邪见时,使用独特的「神」这一术语来指代自我或灵魂的执着,并衍生出六种关于「神」的邪见(如「真有神」、「真无神」等)。 2. 错误作意的具体表述:《中阿含经》使用「净观」指代对感官对象的错误净妙作意;而《杂阿含经》则使用「取色相」来描述面对外境时生起染着的具体表现。 3. 觉支的称呼:《杂阿含经》在论述不正思惟对觉悟因素的阻碍时,将「七觉分」与「七觉支」并称。 4. 邪道的结构:《杂阿含经》详细列举了从「邪见」至「邪定」的「八邪」结构,用以对比不正思惟与正思惟对修行成败的决定性作用。

四、与相关概念的关系

1. 与「无明」及十二因缘的因果关系

在《杂阿含经》的「有因、有缘、有缚法经」中,不正思惟被置于十二因缘般连锁关系的起点之一。当「眼」与「色」相缘时,会生起「不正思惟」,进而生起「痴」(即「无明」);而无明进一步引发「爱」(痴求欲),爱导向「业」,业再导向「眼」(其余耳、鼻、舌、身、意亦同)。因此,不正思惟是无明的因、缘与缚,两者互为因果,构成了生死束缚的循环。

2. 在「食」之连锁关系中的定位

《中阿含经》采用「食」(滋养、因缘)的连锁关系,详细阐明了不正思惟在杂染流转中的因果位置: - 不正思惟的「食」:不正思惟以「不信」为食;「不信」以「闻恶法」为食;「闻恶法」以「亲近恶知识」为食;「亲近恶知识」以「恶人」为食。 - 不正思惟作为「食」:不正思惟本身则是「不正念、不正智」的食。这一连锁进一步向下滋养,依序为:不正念与不正智、不护诸根、三恶行、五盖、无明,最终具足「有爱」。

3. 与「觉观」的关系

在禅修情境下,不正思惟是引发「觉观」(寻伺)干扰的直接原因。修行者若起不正思惟,便会被觉观所困扰,必须通过「舍不正念,专修于正受」来克服。

五、代表性原文引用

1. 《中阿含经》卷十:「不应念法而念,应念法而不念。不应念法而念、应念法而不念故,未生欲漏令生,已生欲漏增长广大;未生有漏、无明漏令生,已生有漏、无明漏增长广大。」 2. 《中阿含经》卷十:「不护眼根、不护意根者,此何因缘?谓不正思惟以净观也。」 3. 《中阿含经》卷十一:「不正思惟有食,非无食。何谓不正思惟食?答曰:不信为食。」 4. 《杂阿含经》卷十一:「眼、色缘,生不正思惟,生痴。……不正思惟者,是无明因缘。无明因缘者,是痴求欲。痴求欲者,是爱。爱因缘者,是业。」 5. 《杂阿含经》卷二十七:「何等为未生五盖令生,已生者重生令增广?谓不正思惟。……何等为未生七觉分令不生,已生者令退?谓不正思惟。」

By SutraAI-generated

中阿含經T0026 · 阿含部

《中阿含經》對「不正思惟」的論述,可從以下數端加以提煉。

一、以「正思惟」與「不正思惟」對舉,以漏之生滅為判準。經云:「有正思惟、不正思惟。若不正思惟者,未生欲漏而生,已生便增廣,未生有漏、無明漏而生,已生便增廣;若正思惟者,未生欲漏而不生,已生便滅,未生有漏、無明漏而不生,已生便滅。」凡夫愚人因「不得聞正法,不值真知識,不知聖法,不調御聖法,不知如真法」而起不正思惟,漏遂增長;多聞聖弟子得聞正法、值真知識、知如真法,起正思惟,漏遂消滅。

二、不正思惟具體表現為六見等邪執。凡夫「不正思惟故,便作是念:『我有過去世,我無過去世,我何因過去世,我云何過去世……今此眾生從何所來,當至何所?本何因有,當何因有?』」於六見中隨見而生「真有神、真無神、神見神、神見非神、非神見神、此是神能語能知能作教作起教起,生彼彼處,受善惡報,定無所從來,定不有、定不當有」等執,經中斥之為「見之弊,為見所動,見結所繫」,令凡夫受生老病死之苦。多聞聖弟子則知苦如真、知苦習、知苦滅、知苦滅道如真,三結盡而得須陀洹。

三、在「七斷漏、煩惱、憂慼法」中,不正思惟亦扮演關鍵角色。「有漏從見斷」一項,即以知見如真而斷不正思惟所起之見結;「有漏從護斷」一項,則以六根對境為例:眼見色時,「護眼根者,以正思惟不淨觀也,不護眼根者,不正思惟以淨觀也」,耳鼻舌身意同理,護則不生煩惱憂慼,不護則生煩惱憂慼。七斷之目為:從見斷、從護斷、從離斷、從用斷、從忍斷、從除斷、從思惟斷。

四、不正思惟處於染法展轉相生之鏈中。經以「食」為喻,層層推求:有愛以無明為食,無明以五蓋為食,五蓋以三惡行為食,三惡行以不護諸根為食,不護諸根以不正念、不正智為食,不正念、不正智以不正思惟為食,不正思惟以不信為食,不信以聞惡法為食,聞惡法以親近惡知識為食,親近惡知識以惡人為食。如是「具惡人已,便具親近惡知識……具不正思惟已,便具不正念、不正智……具無明已,便具有愛」,名為「有愛展轉具成」。此鏈條反覆宣說於多處。

五、術語特點。本經以「不正思惟」為正譯,與「正思惟」相對;以「如真法」(即如實知法)統攝染淨樞紐;以「漏」「煩惱」「憂慼」並列為所斷之法;又以「六見」「見結」「三結」等名數安立邪執之相。全經始終環繞「如理觀察」與「不如理觀察」之別而立論。

雜阿含經T0099 · 阿含部

《雜阿含經》以「不正思惟」一詞貫穿多部小經,從不同側面揭示此概念的內涵與過患,以下分述之。

一、作為緣起鏈中的環節。《雜阿含經》「有因、有緣、有縛法經」以「有因、有緣、有縛」之框架,揭示「不正思惟」是「無明」之因、緣、縛;而「不正思惟」本身復由「緣眼、色」而生,進一步生起於「癡」。由此構成「眼→業→愛→無明→不正思惟→癡」的逆觀緣起鏈,顯示「不正思惟」處於煩惱生起的關鍵節點。

二、作為唯一能令五蓋生起、七覺支不生的內法。第7659經明言:「於內法中,我不見一法,未生惡不善法令生……所謂不正思惟。」此經列舉「貪欲、瞋恚、睡眠、掉悔、疑」等五蓋,與「念、擇法、精進、喜、猗、定、捨」七覺分,指出「不正思惟」能使未生之五蓋令生、已生者增廣,並令未生之七覺分不生、已生者退失。第7621經亦以同樣結構反覆宣說,並以「正思惟」對治。

三、作為令八邪道增長、八正道退失的根源。第7778、7780、7782、7790經同以「於內法中,我不見一法」之語式,分別揭示「不正思惟」能使「邪見、邪志、邪語、邪業、邪命、邪方便、邪念、邪定」等八邪道項生起增廣,並使「正見、正志、正語、正業、正命、正方便、正念、正定」等八正道項不生或退失;「正思惟」則反之能令邪道滅、正道生。第7790經末並提示「如說邪見、正見……七經如上說」「如內法八經,如是外法八經,亦如是說」,顯示此說法另有外法八經之對應。

四、於具體行門與護心實踐中顯其過患。第16476經記載愚癡比丘入村乞食,不善護身、不守根門、心不繫念,「見諸女人,起不正思惟,而取色相,發貪欲心」,貪欲發後身心燒燃、馳逸、不樂空閑,乃至捨戒退減。第7956經記拘薩羅國長者與王婇女同遊之時,自稱「無一剎那不正思惟」,以護象行正道、自護其心、自護其身三事為喻,佛讚其「善護心」。第19038經則記比丘居林中「入晝正受」而起「不正思惟」,林神起念欲善巧覺悟之。

術語特點:此部經一貫以「不正思惟」與「正思惟」對舉,未見使用「邪思惟」、「惡思惟」、「非理作意」等其他譯名;其框架術語則包含「因、緣、縛」、「於內法中」、「五蓋」、「七覺支/七覺分」、「八正道/八邪道」,且五蓋、七覺分與八正道之項目排列順序固定。

阿毘達磨俱舍論T1558 · 毘曇部

《阿毘達磨俱舍論》以「非理作意」一詞表述「不正思惟」之概念,並以「如理作意」作為對立面。以下分述論中對此概念之論述要點:

一、術語對舉與業之分類 論中以「非理作意」與「如理作意」對舉。有論師以染業名「不應作」,謂其從非理作意所生;以善業名「應作」,謂其從如理作意所生。又有餘師從軌則合不合之角度立說,與前二說並存。

二、於十二緣起中之位置 論引他契經云:「非理作意為無明因,無明復生非理作意」,並引「眼色為緣生癡,所生染濁作意」之經文,認為觸位之非理作意與受俱轉,無明為其緣。有餘師謂此非理作意攝於取支,論主層層破斥:若言非理作意與取相應,則愛、無明亦應攝於取支;設許彼攝,愛與無明亦彼攝故,應不別立為緣起支。又以理證知:(一)非離無明受能為愛緣,以阿羅漢受不生愛故;(二)非無倒觸能為染受緣;(三)非離無明觸可成顛倒,以阿羅漢觸非顛倒故。由此推知,觸時非理作意必引無明,無明為緣生受,受緣生愛。

三、生起煩惱之三因緣 頌曰:「由未斷隨眠,及隨應境現,非理作意起,說惑具因緣。」論釋三因緣:(一)未斷未遍知之欲貪隨眠;(二)順欲貪境現在前;(三)緣彼非理作意起。如其次第,即因、境、加行三力。餘煩惱起,例此應知。論中復引阿毘達磨之說:欲貪隨眠由三處起,一未斷遍知故,二順彼經法正現在前故,三於彼正起非理作意故。又以理證:若阿羅漢治道已生,煩惱畢竟不起,則不應退起煩惱;若彼道未生,未能永拔煩惱種故,應非漏盡。

四、劫初人類生活演變之敘述 論於敘述劫初時,因男女根殊形相亦異,宿習力故便相瞻視,「因此遂生非理作意,欲貪鬼魅惑亂身心,失意猖狂行非梵行。人中欲鬼初發此時」,以「非理作意」之產生標誌人類欲貪行為之始。
