What Is This Concept Talking About? (这个概念在说什么)

In the Buddhist understanding of the mind, non-faith (*āśraddhya* / 不信) is not merely a neutral absence of belief or a healthy posture of intellectual skepticism. It is classified as an active, primary mental affliction (*kleśa*)—a state of inner turbidity, cynicism, and heart-closure that paralyzes our capacity to cultivate goodness and leads to long-term spiritual degradation.

To understand *āśraddhya*, one must first understand its opposite: faith (*śraddhā* / 信). In classical Buddhist psychology, *śraddhā* is defined as a heart-cleansing clarity (*citta-prasāda*), a serene openness and trust in truth, the law of cause and effect (karma), and the possibility of human liberation. *Āśraddhya* (不信), conversely, acts like a drop of ink in clear water. It pollutes the mind, rendering it incapable of being touched or transformed by truth.

The classical scriptures across different traditions analyze *āśraddhya* through several precise structural dimensions:

1. The Core Analogy: The "Burnt Seed" (燒種子)

In the *Mahāratnakūṭa Sūtra* (*Dà Bǎojī Jīng* / 《大寶積經》), non-faith is described through a haunting metaphor: "It is like a burnt seed, which cannot sprout roots or shoots" (猶如燒種子,不生根牙等).

In Buddhist thought, every human mind possesses the latent potential for wisdom, compassion, and liberation—referred to as "wholesome seeds" or "pure/white dharmas" (*báifǎ* / 白法). Faith is the fertile moisture and soil that allows these seeds to germinate. When *āśraddhya* takes hold, it acts like intense fire, scorching the seeds of goodness at a psychological level. Once a mind becomes thoroughly entrenched in non-faith, wholesome mental states—such as generosity, restraint, empathy, and meditative effort—simply cannot take root.

2. The Causation Network: The Chain of "Nutriment" (食)

In the *Madhyama Āgama* (*Zhōng Āhán Jīng* / 《中阿含經》), the Buddha presents a profound dynamic model of how non-faith arises and how it feeds further suffering, using the concept of "nutriment" (*shí* / 食)—that which sustains and propels a state of being.

Non-faith does not emerge out of thin air; it is nurtured through a specific systemic loop: $$\text{Evil People (惡人)} \rightarrow \text{Associating with Bad Friends (親近惡知識)} \rightarrow \text{Hearing Unwholesome Teaching (聞惡法)} \rightarrow \text{Non-Faith (不信)}$$

Once *āśraddhya* is established in the heart, it becomes the direct "nutriment" for a cascading sequence of mental and behavioral decline: $$\text{Non-Faith (不信)} \rightarrow \text{Unwise Attention (不正思惟)} \rightarrow \text{Lack of Mindfulness/Wisdom (不正念、不正智)} \rightarrow \text{Unguarded Senses (不護諸根)} \rightarrow \text{Three Unwholesome Actions (三惡行)} \rightarrow \text{Five Hindrances (五蓋)} \rightarrow \text{Ignorance (無明)} \rightarrow \text{Craving for Existence (有愛)}$$

This causal chain reveals that non-faith is the critical hinge between external negative influences and internal fundamental ignorance (*avidyā* / 無明). It turns toxic external inputs into an internal engine of suffering.

3. Mental Trait: Cynicism, Rumination, and Unrealistic Expectation

The *Mahāratnakūṭa Sūtra* provides a razor-sharp clinical breakdown of the internal state of a mind caught in *āśraddhya*: * Constant Doubt and Agitated Rumination (常懷疑惑,常起尋伺): The mind is endlessly caught in anxious, circular questioning—*"Will I succeed or not? What is this really about?"* It endlessly analyzes (*xúncì* / 尋伺) without ever arriving at conviction or peace. * Universal Suspicion (疑一切): A pervasive distrust toward genuine spiritual guides, noble friends, or path-tested truths. * Slandering the Path while Demanding Fruits (住在於一邊,誹謗於正道;不行而希望,賢聖諸佛法): The non-believing mind stands on the sidelines criticizing the process, refusing to engage in disciplined practice (*bù xíng* / 不行), yet paradoxically demands or expects the peace, wisdom, and fruits achieved by the noble ones (*xīwàng* / 希望).

4. Spiritual Classification across Scripture Families

Across the classical canons, *āśraddhya* occupies a pivotal place: * The Four Obstacles to the Path (四種障道之法): In the *Mahāratnakūṭa Sūtra*, *āśraddhya* is listed alongside indolence (*xièdài* / 懈怠), arrogance (*wǒmàn* / 我慢), and hatred (*chēnhuì* / 瞋恚) as one of the four primary barriers preventing a Bodhisattva from realizing Buddhahood [18220]. * The Realm of Non-Faith (不信界): In the *Samyukta Āgama* (*Zá Āhán Jīng* / 《雜阿含經》), mental states are described in terms of "realms" (*dhātu* / 界) [6235]. When a person harbors *āśraddhya*, their mind becomes structurally attuned to and co-arises with the "realm of non-faith," binding them to moral laxity and spiritual dullness. * The Disinclined Mind (不信樂意): The *Samyukta Āgama* notes that when the mind harbors *bùxìnlèyì* (a lack of joy and trust in the Dharma), it is completely blocked from comprehending profound, subtle spiritual truths (*shēnmiaò shuō* / 深妙說) [11181].


Walkthrough in Daily Life (生活里的走查)

To truly grasp *āśraddhya*, we must step out of ancient terminology and look at a typical day in modern life. Let us trace how the canonical "Chain of Nutriment" operates step-by-step in today's world.

``` [Toxic Environment / Cynical Media] ↓ (Associating with Bad Friends / Hearing Unwholesome Teachings) [Internalized Cynicism & Disbelief] ↓ (Non-Faith / 不信) [Cynical Interpretation of Reality] ↓ (Unwise Attention / 不正思惟) [Doomscrolling & Sensorial Overload] ↓ (Unguarded Senses / 不護諸根) [Toxic Online Behavior / Reactivity] ↓ (Three Unwholesome Actions / 三惡行) [Anxiety, Burnout, Existential Dread] ↓ (Five Hindrances & Ignorance / 五蓋、無明) ```

Step 1: "Bad Friends" and "Unwholesome Teachings" (親近惡知識、聞惡法)

Imagine waking up and immediately checking social media feeds optimized for rage-bait, hyper-cynicism, and transactional worldview algorithms. You absorb comments insisting that "everyone is selfish," "kindness is just a hypocritical performance," or "nothing ever gets better." This constant intake of nihilistic narratives is precisely what the scriptures call "hearing unwholesome teachings" from "bad influences."

Step 2: The Germination of Non-Faith (生不信)

After months of absorbing this atmosphere, an internal shift occurs. Your heart hardens. When you read about an act of genuine selflessness or encounter a spiritual teaching advocating inner transformation, your immediate, visceral reaction is a bitter scoff: *"What's their angle? What are they trying to sell me?"*

This is not rational judgment; it is the mental state of non-faith (*āśraddhya*) taking root. The seed of trust in human goodness and moral cause-and-effect has been scorched.

Step 3: Unwise Attention and Obsessive Rumination (不正思惟、常起尋伺)

Now governed by *āśraddhya*, your attention naturally gravitates toward bad news and hidden motives (unwise attention / 不正思惟). At night, your brain enters endless loops of obsessive rumination (常起尋伺): *"Is my job safe? Is my partner lying to me? What if everything collapses?"* Because you lack trust in the underlying order of cause and effect or in your own capacity to cultivate peace, your thoughts spin out of control.

Step 4: Unguarded Senses and Unwholesome Actions (不護諸根、三惡行)

Lacking an inner anchor of faith, you feel empty and anxious. To soothe this discomfort, you leave your senses completely unguarded (不護諸根): doomscrolling until 2 AM, compulsively buying things, or consuming stimulants. When interacting with colleagues or family, your underlying cynicism spills out as sharp, sarcastic remarks, backbiting, or passive-aggressive behavior (three unwholesome actions of body, speech, and mind).

Step 5: Slandering the Path while Expecting Peace (住在於一邊,誹謗於正道;不行而希望)

Perhaps you feel exhausted by this mental state and buy a self-help or meditation book. But as soon as you open it and read "sit quietly and observe your breath," the *āśraddhya* steps in again: *"This is useless. Breathing won't pay my bills."* You put the book down without ever practicing even five minutes of disciplined meditation (不行 / non-practice), yet you complain bitterly that "nothing works" and wonder why you haven't attained inner peace (希望 / demanding fruits).

Common Mismapping in Daily Life

Where do modern people most frequently mistake this concept? * Mistake 1: Conflating *āśraddhya* with *scientific thinking*. People often say, "I'm a rational person, so I don't believe in anything easily." But scientific inquiry is open-minded, empirical, and willing to test hypotheses. *Āśraddhya* is not open inquiry; it is a rigid, emotional defensiveness that refuses to test the hypothesis of inner transformation altogether. * Mistake 2: Assuming non-faith is just a passive "lack of religious affiliation." In Buddhism, a non-religious person who maintains a clear, open, trusting, and warm heart toward goodness has abundant *śraddhā* (faith). Conversely, a religious practitioner who attends rituals daily but remains deeply suspicious, judgmental, and spiritually cynical is steeped in *āśraddhya*.


Why Contemporary People Need It (当代人为什么需要它)

Modern society is facing a epidemic of cynicism and existential fatigue. We live in an information landscape engineered to exploit outrage and distrust. In business, relationships, and culture, "naive trust" is often ridiculed, while "cynical detachment" is rewarded as a sign of sophistication.

Understanding the Buddhist diagnostic of *āśraddhya* offers modern individuals a crucial mirror and a way out:

1. It Exposes Cynicism as a Pathological State, Not Wisdom

Modern culture often mistakes cynicism for intelligence. The Buddhist taxonomy of the mind flips this narrative on its head: **cynicism (*āśraddhya*) is not sophistication; it is a cognitive disability.** It is a state of mental pollution that locks the individual out of experiencing deep joy, genuine human connection, and spiritual relief. When you realize that your pervasive skepticism is actually causing your burnout and anxiety, you gain the leverage needed to change it.

2. Dialogue with Modern Psychology and AI Culture

* Neurobiology and Cognitive Science: Modern neuroscience recognizes the concept of "negativity bias" and "learned helplessness"—states where the brain becomes hardwired to expect threat, deceit, and failure, filtering out positive inputs. This closely aligns with how *āśraddhya* acts as an epistemic filter blocking "white dharmas" (白法). * Algorithmic Echo Chambers: In an era where AI algorithms curate news feeds to maximize click-through via fear and outrage, our environment constantly feeds us "unwholesome information" (聞惡法). Understanding the "Nutriment Chain" helps us realize that digital hygiene (guarding what enters through our eyes and ears) is essential for safeguarding our mental health. * The Crucial Limitation of Science vs. Dharma: While cognitive behavioral therapy (CBT) or neuroscience can help us recognize cognitive distortions or recalibrate dopamine pathways, they generally treat mental states merely as biological mechanisms to be optimized for worldly function. Buddhism goes deeper: it views *āśraddhya* as an existential fetter that binds us to the entire cycle of suffering (samsara). Removing non-faith is not just about feeling better at work; it is about liberating the consciousness at its roots.


Common Misreadings and Clarifications (常见误读与澄清)

1. "Does Buddhism demand blind obedience and prohibit doubt?"

Clarification: Absolutely not. The Buddha famously instructed in the *Kālāma Sūtra* not to believe anything simply out of tradition, authority, or rumor, but to test it through personal experience.

The distinction lies between healthy inquiry (*vīmāṃsā* / 觀察、sincere questioning) and afflicted non-faith (*āśraddhya* / 不信). Healthy inquiry stems from a desire to know the truth; it is active, open, and willing to follow evidence wherever it leads. *Āśraddhya*, on the other hand, is an emotional armor. It does not want truth; it wants to be safe from disappointment, and so it prejudges, dismisses, and doubts everything (*疑一切*) to avoid taking the risk of practicing.

2. "Isn't 'Faith' in Buddhism just believing in dogmas like reincarnation or gods?"

Clarification: In classical Buddhism, the primary object of faith (*śraddhā*) is not supernatural dogmas, but three fundamental realities: 1. The Reality of Suffering and Liberation: Believing that inner freedom is actually achievable. 2. The Law of Karma (Cause and Effect): Deeply trusting that wholesome actions lead to peace and unwholesome actions lead to suffering. 3. The Efficacy of the Path: Trusting that if one practices morality, stillness, and wisdom, specific psychological transformations will occur.

When scriptures say non-faith causes one to "fall into evil realms" (*趣至惡處,生地獄中*), it is not describing a vengeful deity punishing non-believers. It is describing natural psychological gravity: if a person genuinely disbelieves in cause and effect, they will act recklessly, destroy their relationships, pollute their mind with greed and anger, and create a living hell for themselves and others—both in this life and beyond.

3. "Can't I just be a spiritual spectator without committing to practice?"

Clarification: The *Mahāratnakūṭa Sūtra* explicitly warns against the stance of "standing on the sidelines, slandering the path, refusing to practice yet hoping for the fruits of the saints" (住在於一邊,誹謗於正道;不行而希望,賢聖諸佛法).

*Āśraddhya* often manifests as the "armchair critic"—someone who reads endless spiritual literature, critiques every teacher and technique, but never commits to a daily seat on the meditation cushion. Buddhism insists that spiritual truth is experiential. Just as reading a menu will never satisfy hunger, analyzing teachings with a closed, cynical mind will never yield liberation. True faith (*信成就*) is demonstrated not by verbal assertion, but by stepping onto the path and testing it with one's own life.

Canonical EntryAI-generated

一、 定义与核心要义

在佛教经典中,“不信”(āśraddhya)被视为一种极其严重的心理垢染与修行障碍。它不仅是众生无法生起清净善法的根本原因,更是导致生命堕入恶趣、在生死中长夜受苦的罪魁祸首。在阿含部与宝积部等经典中,“不信”被赋予了多维度的阐释:它既是因缘流转链条中滋养“无明”与“有爱”的关键环节,也是与特定“界”相俱的心性呈现,更是菩萨修行道路上必须断除的四大障道法之一。

二、 主要阐述

1. 堕落恶趣与长夜受苦的果报危害 各经一致强调了“不信”所带来的惨烈果报。在《中阿含經》中,尊者舍梨子明确指出,愚痴凡夫若成就“不信”,在其身坏命终之后,必将“趣至惡處,生地獄中”。而在《雜阿含經》中,佛陀亦针对受大苦痛的众生开示道,对于如来所说之法产生不信的愚痴之人,必将在漫长的生死黑夜中“長夜受苦”。这表明“不信”直接关联着地狱等恶趣的苦报。

2. 阻碍善法生起的“烧种子”效应 “不信”对修行最具毁灭性的影响在于其对善根的摧毁。在《大寶積經》中,缺乏信心、怀抱不信的人被形象地比喻为“猶如燒種子,不生根牙等”,由于种子已被烧毁,不信之人终究“不生諸白法”。此外,在《雜阿含經》中,“不信”表现为“不信樂意”,这种心理垢染会直接阻碍众生理解佛陀所宣说的深妙法义,使人无法领悟深奥的解脱智慧。

3. 滋养无明与有爱的因缘链条 《中阿含經》从因缘流转的动力学角度,详细剖析了“不信”在杂染流转中的枢纽作用。经中引入“食”(滋养源)的概念,指出“不信”并非凭空产生,而是以“聞惡法”为食,而“聞惡法”又以“親近惡知識”为食,进而追溯到以“惡人”为食。一旦“不信”生起,它又会成为“不正思惟”的滋养源(食),由此展转滋养“不正念、不正智”、“不護諸根”、“三惡行”、“五蓋”,最终导致“無明”与“有愛”的具足。这一链条揭示了“不信”是推动众生不断堕落、流转生死的核心动力。

4. 不信的具体表现与心态特征 在具体心相上,“不信”表现为多疑与诽谤。根据《大寶積經》的描述,不信者内心常怀犹豫,不断思忖“我當成不成?是事為云何?”,并且“常起尋伺”,对一切诸佛及声闻弟子“疑一切”。他们不仅自己不依教奉行,反而“住在於一邊,誹謗於正道”,甚至在不修行的状态下奢望获得圣法,即所谓“不行而希望,賢聖諸佛法”。

三、 不同部类与译本的表述差异

在不同的经典和译本中,对于“不信”及其相关概念的术语表述存在明显的部类特色:

1. 《中阿含經》(《中阿含經》)的术语特色: - 将因缘滋养关系独特地表述为“食”。 - 将与“不信”相对的清净信心称为“上信”。 - 在烦恼分类中,存在“五蓋”与“五葢”两种字形的混用。 - 将身口意三业的恶行统称为“三惡行”。

2. 《雜阿含經》(《雜阿含經》)的术语特色: - 引入“界”的概念,将不信的状态表述为与“不信界”相俱,而将信心表述为与“信界”相俱。 - 将阻碍理解深妙法义的心理障碍表述为“不信樂意”。

3. 《大寶積經》(《大寶積經》)的术语特色: - 将“不信”定位为“四種障道之法”之一(其余三者为懈怠、我慢、瞋恚)。 - 将因信而生的清净善法称为“白法”。 - 将成就广大法所需的欢喜信受之心称为“信樂心”。 - 将因深信因果而远离“一疑、二惑、三不決定”的状态称为“信成就”。 - 将能断尽一切烦恼的深切信心称为“深心信清淨”。

四、 与相关概念的关系

1. 与“信”及“信成就”的对立 “不信”与“信”是完全对立的心理状态。在《雜阿含經》中,它们分别对应“不信界”与“信界”;在《中阿含經》中,“不信”导致堕落地狱,而“上信”则能灭苦并证得斯陀含或阿那含果。在《大寶積經》中,对治不信需要达到“信成就”或“深心信清淨”,如此方能断除因不信而产生的“疑、惑、不決定”,并能“乘彼道”以断尽烦恼。

2. 与“恶知识”、“闻恶法”的因果关系 根据《中阿含經》,“不信”并非孤立生起,而是由外在的恶因缘诱发。其因果链条为:恶人 $\rightarrow$ 亲近恶知识 $\rightarrow$ 闻恶法 $\rightarrow$ 生不信。这表明,不信的产生与个体所处的环境及所听闻的教导密切相关。

3. 与“不正思惟”及“无明”的递进关系 在流转门中,“不信”是“不正思惟”的直接原因(以不信为食)。不正思惟进而引发不正念、不正智,最终导致无明与有爱的具足。因此,“不信”是连接外在恶缘与内在根本无明的中介枢纽。

4. 与“疑惑”、“寻伺”的伴生关系 “不信”在内心活动中往往与“疑惑”和“寻伺”相伴相随。不信者由于缺乏对真理的决定见,因而对一切佛法常怀犹豫,不断进行无益的寻伺,从而陷入“疑一切”的泥潭中。

五、 代表性原文引用

1. 《中阿含經》:“愚癡凡夫成就不信,身壞命終,趣至惡處,生地獄中……若有成就上信,彼身壞命終,趣至善處,生天善處。” 2. 《中阿含經》:“不信亦有食,非無食。何謂不信食?答曰:聞惡法為食……不正思惟以不信為食。” 3. 《雜阿含經》:“若眾生不信,與不信界相俱;犯戒,與犯戒界相俱……若眾生信,與信界相俱。” 4. 《雜阿含經》:“如來所說,有不信者,是愚癡人長夜受苦。” 5. 《大寶積經》:“不信之人,終不能生諸白法,猶如燒種子,不生根牙等。” 6. 《大寶積經》:“常懷疑惑常起尋伺,疑一切諸佛及聲聞等……住在於一邊,誹謗於正道,不行而希望,賢聖諸佛法。”

中阿含經T0026 · 阿含部

《中阿含經》論「不信」,主要從兩個層面展開。第一,在探病情境中以對比方式論「不信」之果報。舍梨子尊者慰問給孤獨長者時,先舉「愚癡凡夫成就不信,身壞命終,趣至惡處,生地獄中」為戒懼,再反襯長者「無有不信,唯有上信」,說明「上信」可滅苦痛、生極快樂,乃至證得斯陀含、阿那含果。此處「不信」與「上信」對舉,明確將「不信」列為導致墮惡趣的根本惡法,與「惡戒」「不多聞」「慳貪」並列為凡夫墮落之因。第二,以「食」之譬喻建立染法展轉相生之次第。本經宣說:「不正思惟亦有食,非無食。何謂不正思惟食?答曰不信為食。」又說:「不信亦有食,非無食。何謂不信食?答曰聞惡法為食。」由此將「不信」定位於一條由外而內、由粗至細的染污鏈條之中:惡人→親近惡知識→聞惡法→不信→不正思惟→不正念、不正智→不護諸根→三惡行→五蓋→無明→有愛。本經以「具……已,便具……」的反覆句式,強調此鏈條之展轉具成,構成流轉生死的緣起次第;其中,「不信」為由外向內、由聞慧轉入思惟的關鍵環節。又以「大海」展轉成滿為喻,顯示每一後項以前項為「食」、為依待之條件,從而展轉增長。從術語形式觀察,本經一律使用「不信」一詞,未見其他異名,其正面對應為「上信」;又傳本中「五葢」與「五蓋」二形並出(作「五葢」,作「五蓋」),屬同經用字之異。凡此皆明:「不信」在本經中既是墮惡趣的獨立惡法,又是啟動染污思惟、進而引發無明與有愛之關鍵心所。

雜阿含經T0099 · 阿含部

本經論「不信」,從兩個側面展開。

一、以「界」明其體性。世尊告諸比丘:「眾生常與界俱,與界和合。不信時與不信界俱,犯戒時與犯戒界俱,無慚無愧時與無慚無愧界俱;信心時與信界俱,持戒時與持戒界俱,慚愧心時與慚愧界俱。」此中「不信」並非孤零零的一項心所,而是與「信」相對而立的一對——「不信時與不信界俱」,「信心時與信界俱」。經文用「不信界」與「信界」兩個詞,將「不信」安置於「界」的範疇之中。此處「界」非地水火風等物質性之界,而是指眾生內心種種品性所歸屬的範疇,如「犯戒界」、「持戒界」、「無慚無愧界」、「慚愧界」等皆屬此義。世尊以此教誨諸比丘「當善分別種種諸界」,意謂須辨明此等品界各自之相,使心有所趨避。

二、以並列顯其相對。同段結尾以「如信、不信,如是精進、不精進,失念、不失念,正受、不正受,多聞、少聞,慳者、施者,惡慧、善慧,難養、易養,難滿、易滿,多欲、少欲,知足、不知足,攝受、不攝受界俱,如上經如是廣說」的方式,將「不信」嵌入一個龐大的二元對照系列之中。此一鋪排顯示,「不信」在經文作者的觀念中,並非孤立之惡,而是一系列相對品類中的一支——每一對中,惡法與善法各有其所屬之界,眾生之心隨時與之俱生俱滅。值得注意的是,本經一律以「不信」二字為正名,未見異譯、別稱或訓釋性替代語。

三、以不信如來所說結其罪果。大目犍連見一大身眾生「身如樓閣,啼哭號呼,憂悲苦痛,乘虛而行」,世尊釋其本緣:此眾生過去為屠牛兒,「以屠牛因緣故,於百千歲墮地獄中,從地獄出,有屠牛餘罪,得如是身,常受如是憂悲惱苦」。世尊並云:「我亦見此眾生,而不說者,恐人不信。所以者何?如來所說,有不信者,是愚癡人長夜受苦。」此處「不信」專指不信如來所說正法,世尊將此不信者直稱為「愚癡人」,並預設其「長夜受苦」之果報。與前段「不信界」之屬性安立不同,此處之「不信」是帶有強烈價值判斷與果報預設的用語。

綜上,本經論「不信」所用術語即「不信」、「不信界」,未見其他異譯別稱;論述方式兼攝「界和合」的屬性安立與「不信如來所說」的果報警誡二途,二者並行而不相混。

大寶積經T0310 · 寶積部

《大寶積經》對「不信」的論述,主要將其歸納為菩薩修道的重大障礙,並與懈怠、我慢、瞋恚並列為四種障道之法。

一、不信作為障道之法

經中明確將「不信」列為菩薩四種障道之法之一。世尊告護國菩薩言:「菩薩有四種障道之法。何等為四?一者懈怠,二者不信,三者我慢,四者瞋恚。是為四種障道之法。」 由此可知,「不信」在此經中被視為直接遮蔽菩提正道的心所,與懈怠、我慢、瞋恚同列為菩薩所應遣除的四大煩惱障。

二、不信的表現——疑惑與誹謗正道

不信的具體表現,經中以「疑惑」一語展開。世尊開示:「汝阿逸多!當知疑惑與諸菩薩為大損害。」 疑惑之人「遠離一切殊勝善根」,於中「不生欣樂,不能出現修習善法」,由此可見疑惑(不信)的過患,在於使菩薩遠離一切勝妙善根,不能生起欣樂修習之心。經中亦描述疑惑者的相狀:「而常起尋伺,住在於一邊,誹謗於正道,不可得菩提,此是懈怠心,非是菩提相。斯人疑一切,諸佛及聲聞,不行而希望,賢聖諸佛法。」 此處「疑一切」即是不信三寶的表現——既不信諸佛,亦不信聲聞,卻希求賢聖佛法而不行實踐。此段並將不信與懈怠心相連,揭示二者互為助緣的關係。

三、信所對治的三法

相對於「不信」的障道,經中亦闡明「信」的成就與對治功能。經云:「彼菩薩如是信已得離三法:一疑、二惑、三不決定。善男子!菩薩摩訶薩成就如是信,名為信成就。」 此處所離的「疑、惑、不決定」三法,正是「不信」心所的內涵——對因果、苦報、三寶等起猶豫、迷惑、無法印可之狀。一旦建立正信,便能遠離此三過患,即名為信成就。其中「不決定」一詞,特指對善法功德不能作決定信受之心,為此經描述不信狀態的獨特用語。

四、信為成法之要

經中進一步強調信的重要性,其偈頌云:「非但由言說,能成安樂果,要有信樂心,能成廣大法。亦非唯心量,能獲勝堪任,由一法能成,諸有所作事,知其殊勝已,為佛故應修。」 此頌指出,成就安樂之果,不能僅憑言說或心量揣度,必須依於「信樂心」,方能成就菩薩一切所作之事。

五、術語特色

本經論「不信」時,常以「疑惑」「不決定」並稱。「疑惑」兼具疑與惑二義,「不決定」則特指對因果、三寶功德不能印可決定之心。三詞互用,從不同側面勾勒「不信」心所的相貌,構成此經獨特的術語體系。
