What This Concept Means

In Buddhist soteriology, **"Obstructive Conditions" or "Impediments to Spiritual Progress" (留難, Sanskrit: *antarāyika-dharma*, Pali: *antarāyika-dhamma*)** refers to the demonic disturbances, external intimidations, temptations, internal mental distractions, doubts, and misleading pseudo-teachings that a practitioner encounters during meditation, fruit-realization, or the cultivation and propagation of Prajñāpāramitā (Perfection of Wisdom).

Etymologically, *antarāyika* derives from *antarāya* (interruption, obstacle, or danger). In the early Śrāvaka canon (such as the *Saṃyukta Āgama*), the primary source of these obstacles is personified as Mara Pāpīman (天魔波旬) or evil demons (惡魔), who seek to disrupt the samādhi (*正受*, meditative absorption) and fruit-attainment of the Buddha and bhikkhunīs. In Mahāyāna scriptures (such as the *Maha-prajñāpāramitā Sūtra*), "impediments" expands to encompass a vast spectrum of "demonic deeds" (*魔事*, *māra-karmans*) and "pseudo-path teachings" (*似道法*) that divert a Bodhisattva from realizing *Sarvajñā* (一切智, Omniscience) and attaining *Avaivartika* (阿惟越致, Non-retrogression).

To understand *antarāyika-dharma* thoroughly within the framework of Buddhist liberation, we must examine its manifestations across different traditions, stages of practice, and canonical texts:

1. Disturbance in Meditation and Fruit-Realization (Āgama Context)

In early texts like the *Saṃyukta Āgama*, the entity initiating impediments is Mara Pāpīman, whose singular goal is to destroy a practitioner's concentration (*正受*, *samāpatti*) and keep them bound to the "fetters of Death-Mara" (死魔縻). * Direct External Threat against the Buddha: When the Buddha walked in meditation at night on Vulture Peak, Mara picked up a huge boulder and crushed it into dust in front of him; or transformed into a giant dragon wrapping around the Buddha's body, spouting thunder and hail; or assumed a young appearance or a hundred pure and impure forms to cause disturbance after the Buddha's awakening. * Interference with Bhikkhunīs in Meditation: Mara repeatedly harassed nuns (such as Aḷavikā, Somā, Selā, Vijayā, Calā, and Upacalā/Sīrupacalā) sitting in meditation in the Blind Forest (Andhavana). Mara typically transformed into a handsome youth (化作年少,容貌端正) to strike up conversations, ask teasing questions, or instigate existential doubts, aiming to shatter their resolve. * Internal Vulnerability: If a monk lacks wisdom (沙門無知), he naturally encounters numerous difficulties, his mind becomes swept away by unwholesome thoughts, and he repeatedly sinks into affliction. Conversely, practice is most noble when one "walks the Dharma despite encountering difficulties" (遭難而行法). If one's faculties and mind remain resolute (諸根心決定), even though it is "difficult to abide in steady absorption" (難住正受住), one can break free from Mara's grip. On the other hand, blindly enduring austerities while bound by desires or attachment to precepts without internal mental liberation leads nowhere.

2. Demonic Distractions in Cultivating and Transcribing Prajñā (Mahāyāna Context)

In the *Maha-prajñāpāramitā Sūtra*, because the profound Perfection of Wisdom is a supreme spiritual treasure, impediments constantly arise during its writing, reciting, contemplating, expounding, and practicing. These impediments manifest in three primary layers: * Deviation in Eloquence and Mindset: The practitioner may struggle to manifest eloquent speech (樂說辯不即生) due to incomplete Paramitās, or conversely, develop sudden arrogant attachment to their own eloquence (樂說辯卒起). During transcription or study, mindsets such as arrogance (偃蹇慠慢), playful distraction (戲笑亂心), disrespectful lightheartedness (輕笑不敬), and mental instability (心亂不定) arise. Mutual discord, mockery, and contempt among practitioners (轉相形笑,共相輕蔑) also function as severe impediments. * Doubt and Abandonment: Practitioners may abandon the sūtra claiming they "find no taste or flavor in it" (不得是經中滋味). Or, when a monk is corrupted, unpredicted Bodhisattvas fall into suspicion, leading to division and the failure to complete the writing and contemplation of the Dharma. * The Trap of "Pseudo-Path" (似道法) and "Obstruction-Path" (遮道法): This is the most dangerous form of impediment. Mara disguises himself as a monk, a radiant golden Buddha, or a sangha to trick Bodhisattvas: 1. *Luring back to Śrāvakayāna:* Disguised monks advise the Bodhisattva to quickly realize Śrotāpanna, Sakṛdāgāmin, Anāgāmin, Arhatship, or Pratyekabuddhahood to escape samsāric suffering immediately. 2. *Preaching Sub-Optimal/Worldly Meditations:* Mara preaches worldly meditations tied to the Three Realms (such as meditation on bones/skeletons, or dhyānas from the First Dhyāna up to the Sphere of Neither-Perception-Nor-Non-Perception) as ultimate, urging immediate cessation of suffering in this life. 3. *Distributing Counterfeit Teachings:* Mara gifts texts of Hinayāna methods under the guise of emptiness, creating discord and interrupting Prajñā practice. 4. *Spurring Attachment to Visions:* Mara displays a glorified Buddha-body to induce craved attachment, depleting the practitioner's pursuit of *Sarvajñā*. 5. *Fabricating Counterfeit Paramitās:* Mara creates a "pseudo-Prajñāpāramitā" and fake versions of Dāna, Śīla, Kṣānti, Vīrya, and Dhyāna Paramitās.

3. Countermeasures Against Impediments

* Swift Action (疾書與疾修行): Since impediments constantly seize opportunities, practitioners transcribing or practicing Prajñā should complete their work swiftly within set timeframes (a month, a year) without leaving gaps for obstacles to take root. * Relying on the Power of the Buddhas (佛力與十方諸佛擁護): Recognizing that individual ego-strength is limited, practitioners rely on the protective intention and blessing of all Buddhas of the ten directions. * Unshakable Awareness and Non-Retrogression (覺知與阿惟越致): Upon reaching the stage of *Avaivartika* (Non-retrogression), a Bodhisattva’s mind becomes unshakeable, unstartled, and free of doubt. They recognize counterfeit "pseudo-paths" (*似道法*) and "obstruction-paths" (*遮道法*) for what they are, refuse to follow external prompts, and step away from demonic affairs.


A Walkthrough in Daily Life

To understand how *antarāyika-dharma* operates without relying on supernatural imagery, let us walk through a contemporary scenario: A modern professional attempting to establish a daily practice of deep focus, personal transformation, or altruistic project work.

``` [Pure Intent / Deep Work Begins] │ ├─► 1. Sensory Interruption / Shock (Boulders & Dragons) ──► External emergencies, sudden notifications │ ├─► 2. Subtle Temptation / Emotional Distraction (Handsome Youth) ──► Social media validation, comfortable diversions │ ├─► 3. Internal Mindset Deviation (Pride, Boredom, Friction) ──► Cynicism ("No flavor in this"), interpersonal conflict │ └─► 4. The Pseudo-Path Trap (Counterfeit Excellence) ──► Settling for superficial hacks, shortcuts, or sub-optimal goals ```

Step 1: External Shock Tactics (The "Boulder and Dragon" Phenomenon)

You sit down at your desk or meditation cushion, determined to cultivate deep concentration or work on a selfless, meaningful initiative. * *The Canonical Parallel:* Mara throwing a boulder that turns to dust, or transforming into a terrifying dragon spitting lightning. * *Daily Mapping:* Just as you settle into quiet focus, your phone blares with an urgent notification, an angry client email arrives, or an unexpected crisis explodes in your work chat. The shock triggers an immediate threat response in your nervous system. If you lack awareness, your mental stability collapses instantly.

Step 2: Seductive Rationalization (The "Handsome Youth" Phenomenon)

You manage to sit quietly in a park or room to meditate or contemplate. * *The Canonical Parallel:* Mara transforming into a handsome youth chatting up the bhikkhunīs in the Blind Forest, subtle questioning of their resolve. * *Daily Mapping:* A subtle voice or urge arises: *"Why are you working so hard? Look at your peers—they are out enjoying dinner, scrolling short videos, acquiring quick wealth. Is this quiet discipline really worth it?"* This is not just a passing thought; it is an *antarāyika-dharma* exploiting your hidden desire for comfort and social approval.

Step 3: Mindset Corruption and Cynicism (Internal Impairment)

You begin reading a profound, transformative book or trying to practice patient listening in a relationship. * *The Canonical Parallel:* Arrogance, lighthearted disrespect, feeling "no taste or flavor in the text," and mutual mockery among practitioners. * *Daily Mapping:* After fifteen minutes, you feel bored and think, *"This teaching lacks flavor; it's useless for my immediate goals."* Or, when practicing in a team or study group, you start noticing fellow members' flaws, engaging in subtle condescension ("转相形笑,共相轻蔑"). The initial noble intent dissolves into workplace friction or intellectual pride.

Step 4: The Pseudo-Path Trap (Settling for Less)

You are aiming for radical emotional liberation and long-term selfless wisdom. * *The Canonical Parallel:* Mara preaching "pseudo-paths" (*似道法*)—offering low-level worldly dhyānas, counterfeiting Paramitās, or encouraging the practitioner to give up the vast Bodhisattva ideal to take a quick shortcut out of personal pain. * *Daily Mapping:* An influential mentor or self-help guru convinces you: *"Why bother trying to change systemic issues or cultivate deep selflessness? Just do this 5-minute breathing hack, maximize your personal productivity, and optimize your comfort."* You trade the deep, challenging path of wisdom for a shiny, gamified substitute ("似般若波羅蜜"). You mistake emotional numbness or temporary relaxation for true spiritual liberation.


Why Contemporary People Need This Concept

Modern life is engineered by algorithms and market incentives to generate continuous, hyper-targeted *antarāyika-dharma*. Understanding this concept provides critical psychological and spiritual immunity:

1. Mapping Algorithmic & Environmental Distractions: Modern attention-economy platforms act precisely like Mara's shapeshifting tactics—using novelty, outrage, and erotic or status-driven lures to interrupt sustained contemplative awareness. Labeling these interruptions as *impediments* rather than personal failures shifts your stance from passive victimhood to active spiritual vigilance. 2. Identifying the Danger of "Good Enough" Shortcuts: Modern culture is flooded with shallow "mindfulness hacks" designed solely to make workers stress-resilient enough to return to burnout cycles. The Buddhist critique of "pseudo-paths" (*似道法*) reminds us not to mistake stress-reduction or worldly tranquility for true insight into impermanence and selflessness. 3. Countering "Practice Cynicism": When practitioners feel that practice "lacks flavor" (*不得滋味*), they often blame the Dharma or give up. Realizing that dryness, doubt, and social conflict within spiritual communities are standard, predictable *impediments* helps one maintain momentum ("遭難而行法").

Cognitive Science / AI Analogy & Its Limitations

* Analogy: In Artificial Intelligence and Machine Learning, *antarāyika-dharma* is analogous to overfitting or getting trapped in a local minimum. A model might discover an easy shortcut that minimizes short-term error (a "pseudo-path"), causing it to stop optimizing toward true global accuracy (*Sarvajñā*). Furthermore, adversarial noise injected into data inputs acts like Mara's sensory distortions, fooling the system into misclassifying reality. * Limitation of the Analogy: AI optimization is a mathematical function operating on dead data parameters without subjective feeling or ethical intent. Buddhist *antarāyika-dharma* operates within the complex web of karmic tendencies, volumetric emotional craving (*tṛṣṇā*), and ego-clinging (*ātma-grāha*). An AI does not experience existential fear or moral courage when confronting an obstacle; a human practitioner overcomes impediments through the cultivation of non-retrogression (*Avaivartika*) and spiritual devotion.


Common Misunderstandings and Clarifications

1. Misunderstanding: "Impediments" refer strictly to external evil spirits or supernatural demons.

* Clarification: While early literature uses personified figures like Mara Pāpīman, Buddhist philosophy explicitly categorizes Mara into four types: *kleśa-māra* (affliction-demon), *skandha-māra* (five-aggregates-demon), *mṛtyu-māra* (death-demon), and *devaputra-māra* (heavenly-demon). Most impediments—such as pride, doubt, boredom, cynicism, and interpersonal friction—are internal afflictions (*kleśa*) projected outward. Mara is fundamentally the personification of one's own ignorance (*avidyā*) resisting awakening.

2. Misunderstanding: Any obstacle in life (like illness, poverty, or bad luck) is a "留難" (impediment).

* Clarification: Not all suffering or hardship constitutes an *antarāyika-dharma*. Physical pain or difficult external conditions become impediments only if they cause the practitioner to lose mindfulness, abandon vows, cultivate resentment, or retreat from the path. If a practitioner meets hardship with resolute faculties ("遭難而行法" / "諸根心決定"), that very hardship becomes fuel (*pāramitā*) for spiritual growth rather than an impediment.

3. Misunderstanding: "Pseudo-path" (*似道法*) means completely evil or immoral behavior.

* Clarification: This is the most dangerous misconception. A "pseudo-path" (*似道法*) often appears highly virtuous, peaceful, and sublime—such as deep states of worldly absorption (dhyānas), strict physical asceticism, or sound śrāvaka practices. It is categorized as an impediment (*antarāyika*) in Mahāyāna not because it is wicked, but because it acts as a subtle trap that lulls a Bodhisattva into premature cessation, preventing the realization of ultimate, unexcelled awakening (*Anuttara-samyak-saṃbodhi*).

Canonical EntryAI-generated

【一、定义与核心要义】「留難」(antarāyika-dharma)在佛教经典中主要指修行者在禅修、证果,或在修持、书写及弘扬般若波罗蜜等深妙佛法时,所遭遇的来自恶魔的嬈亂、恐吓、诱惑,以及自身产生的散乱、疑虑等种种障碍与退转因缘。在阿含部经典中,留难侧重于魔波旬对佛陀及比丘尼禅修的具体干扰;而在般若部经典中,留难则广泛指涉阻碍菩萨成就无上菩提的各种“魔事”与“似道法”。【二、主要阐述】在佛教修行的不同阶段与法门中,留难呈现出不同的表现形式与应对方法:1. 禅修与证果过程中的留难:根据《杂阿含经》的记载,留难的主体多为天魔波旬或恶魔,其目的在于破坏修行者的禅定与证果。魔波旬曾对佛陀的修行制造种种留难,如在佛陀夜间经行时,手执大石在佛前碎成微尘,或化作大龙缠绕佛身、口吐雷雹之声;在佛陀初成佛道时,化作年少或变身作百种净与不净之色进行嬈亂。此外,魔波旬也频繁对在安陀林坐禅或入昼正受的比丘尼(如阿臈毘、苏摩、尸罗、毘闍耶、遮罗及尸利沙遮罗)进行留难,其手段多为化作端正年少进行言语搭讪与诘问,企图动摇其修行决心。在修行实践中,若沙门无知则会多起诸艰难,心随觉自在而数数溺沈没;而“遭难而行法”则是极难能可贵的修行态度。若能诸根心决定,虽“难住正受住”亦能断除死魔的束缚;反之,若被欲所迫、被持戒所缚而盲目行苦行,则无法度脱。2. 般若修持与书写中的留难:根据《摩诃般若波罗蜜经》的记载,菩萨在书写、读诵、思惟、说、正忆念及修行甚深般若波罗蜜时,极易生起留难。这些留难(魔事)表现为:一是辩才与心态偏差,如乐说辩不即生或卒起;二是书写受持时的傲慢、戏笑乱心、轻笑不敬、心乱不定,或修行者之间不和合、转相形笑、共相轻蔑;三是因未得滋味而弃舍经文,或因比丘被破坏而产生疑惑导致不和合。恶魔还会通过伪装进行“似道”留难,如化作比丘劝菩萨证声闻辟支佛果,宣说骨相、三界系禅定等“似道法”劝其今世取苦尽证,假托小乘经典赠予菩萨造成不和合,伪装佛身或佛僧引发贪著以耗减萨婆若,乃至伪造“似般若波罗蜜”等六波罗蜜魔事。应对这些留难,菩萨应当“疾书”与“疾修行”以防留难起契机,并依靠佛力与十方诸佛的拥护念持;同时保持觉知,达到阿惟越致地步,心不动摇,识破并远离恶魔所说的“似道法”与“遮道法”。【三、不同部类与译本的表述差异】在不同经典中,对于留难及相关修行概念的用词存在明显差异:1. 留难主体与行为的称呼:《杂阿含经》使用“魔波旬”或“恶魔”指代制造留难的主体,以“嬈亂”指代其骚扰行为;而《摩诃般若波罗蜜经》则多直接以“魔”或“魔事”来统称这些留难与障碍。2. 禅定状态的表述:《杂阿含经》使用“正受”或“昼正受”指代禅定状态;而《摩诃般若波罗蜜经》则使用“禅那波罗蜜”等六波罗蜜译名。3. 智慧与果位的译名:《摩诃般若波罗蜜经》中使用了丰富的特定大乘译名,如以“萨婆若”指代一切智,以“阿惟越致”指代不退转,以“阿耨多罗三藐三菩提”指代无上正等菩提,并使用“檀那波罗蜜”(布施)、“尸罗波罗蜜”(持戒)、“羼提波罗蜜”(忍辱)、“毗梨耶波罗蜜”(精进)、“禅那波罗蜜”(禅定)等波罗蜜多译名;而《杂阿含经》则使用“沙门”、“死魔縻”等早期佛教术语。【四、与相关概念的关系】1. 留难与魔事:在般若部语境下,留难与“魔事”高度重合。凡是阻碍菩萨书写、受持、修行般若波罗蜜的因缘,皆被称为魔事,这些魔事即是修行的留难。2. 留难与似道法、遮道法:恶魔为了制造留难,会宣说与正法相似的“似道法”(如骨相、世间禅定等),诱导菩萨退回小乘或世间定中,这些似道法在本质上即是阻碍无上菩提的“遮道法”。3. 留难与正受、死魔縻:在阿含部中,留难是针对修行者进入“正受”的干扰。修行者若能克服留难、诸根心决定,便能稳固住于正受,从而断除“死魔縻”(死魔的束缚)。【五、代表性原文引用】1. 《杂阿含经》:“魔波旬作是念:『沙門瞿曇在耆闍崛山夜經行,我當往為作留難。』作是念已,執大石,於佛前碎成微塵。”;“時,比丘尼作是念:『此是惡魔欲作留難,嬈亂我心。』”;“難住正受住,諸根心決定,斷除死魔縻,不隨魔所去。”2. 《摩诃般若波罗蜜经》:“甚深般若波羅蜜,是中多留難。……以是故,善男子、善女人,書般若波羅蜜時當疾書,修行時當疾修行。”;“魔作似般若波羅蜜,似禪那、似毘梨耶、似羼提、似尸羅、似檀那波羅蜜。……菩薩摩訶薩於此魔事覺知,知已遠離。”;“魔作似道法、遮道法持與菩薩。阿惟越致菩薩不信他語、不隨他行,識知魔事。”

中阿含經T0026 · 阿含部

《中阿含經》論及「留難」一義,並非以「留難」二字直接立名,而是以「障礙」為核心術語,透過「欲有障礙」這一命題展開。經中敘事框架為:阿梨吒比丘(本伽陀婆梨)起惡見,執「行欲者無障礙」,謂放縱五欲不構成修行障難;諸比丘往訶,明言「欲有障礙,世尊無量方便說欲有障礙」,阿梨吒強力執惡見不肯捨,一向說「此是真實,餘者虛妄」。佛親加訶責,斥其「愚癡人」,謂「我不一向說,汝一向說」,並印可諸比丘所解:「欲有障礙」方為正說。

本經論述留難之獨特側面,在於將障難之根源歸於「欲」本身,而非外在人事之阻撓。佛以八種譬喻極言欲之為障:欲如骨鏁、欲如肉臠、欲如把炬、欲如火坑、欲如毒蛇、欲如夢、欲如假借、欲如樹果。此八喻由不同角度顯示欲的留難性質:骨鏁喻其堅固難脫,肉臠喻其少味多患,把炬喻其反燒自身,火坑喻其陷沒,毒蛇喻其致命,夢喻其虛妄不實,假借喻其非己所有終須歸還,樹果喻其招折枝之禍。諸比丘重述此八喻時,佛再一一印可,形成雙重確認的經文結構。

術語形式方面,本經用「障礙」而非「留難」「遮難」「魔事」等詞;稱五欲單用一「欲」字,不作「五欲」「五塵」;稱錯誤執見為「惡見」,稱執著之態為「強力執」;稱佛之教化方式為「無量方便說」。經中「行欲者無障礙」與「欲有障礙」構成對舉命題,前者為所破之邪執,後者為所立之正見,全經論證即圍繞此一對反展開。

就論述結構言,本經先以僧團內部糾正失敗(眾多比丘不能令捨惡見)鋪陳,再引入佛之親裁,顯示此障難之深重——非僅外在留難,乃內心惡見自障,須佛親訶方能破斥。佛訶辭中「汝從何口聞我如是說法」一句,直指阿梨吒之障在於聞法而曲解,以邪分別自設障難。

雜阿含經T0099 · 阿含部

《雜阿含經》論「留難」,以「為作留難」為固定用語,幾乎專指魔波旬主動對修行者施加的障難。全經所見,此詞反覆出現於佛及弟子遭魔擾亂的敘事框架中,構成高度程式化的表達:魔波旬先「作是念」,言「我今當往,為作留難」,繼而變化形貌前往擾亂。

就施者而言,留難之主體一律為「魔波旬」(又稱「惡魔波旬」「天魔波旬」),經中不將此詞用於人與人之間的障礙,而專屬於魔對聖者及其弟子的干擾。

就受者而言,留難之對象涵蓋佛本人與比丘尼弟子。佛在王舍城耆闍崛山夜間經行時,波旬碎大石、化大龍以擾之;佛初成道於菩提樹下時,波旬化年少、作百種淨不淨色以擾之。比丘尼方面,阿臈毘、蘇摩、尸羅、毘闍耶、遮羅、尸利沙遮羅諸比丘尼於安陀林坐禪時,波旬皆化作年少容貌端正者前往,以言辭誘擾。

就手法而言,波旬為作留難之方式以「化作年少,容貌端正」最為典型,意在以色相、言說動搖修行者之心;對佛則用神力變化,如碎石化龍、作百種色相等。

就應對而言,經中呈現固定模式:佛或弟子覺知「惡魔波旬欲作嬈亂」,即以偈頌回應,表明心不染著、不為所動。尸羅比丘尼之覺知過程尤為具體:先起念「此是何人?欲恐怖我。為人?為非人?為姦狡人?」,思惟後生知覺「此是惡魔欲作留難」,即說偈以拒之。此處「留難」與「恐怖」並舉,顯示留難兼含威嚇與誘惑雙重面向。

就相關術語而言,本經除「留難」外,亦用「嬈亂」指稱同一類魔事;用「障閡」「障礙」指內心自生之阻隔,如比丘入他家乞食,若執著施與不施,則「自生障閡」「不生障礙」——此處障礙非由外魔施加,而源於自心貪求,是留難概念之內在化延伸。此外,「難」「艱難」用於泛指修行路上之困厄,「障」用於總稱一切可脫離之困苦,語義較「留難」為寬。

綜上,《雜阿含經》以「為作留難」為核心動詞片語,將留難嚴格限定為魔波旬對修行者的主動干擾,敘事高度程式化,並區分外魔之留難與內心自生之障閡,二者構成由外而內的障難光譜。

摩訶般若波羅蜜經T0223 · 般若部

《摩訶般若波羅蜜經》論「留難」,主要環繞書寫、讀誦、思惟、說、正憶念、修行般若波羅蜜時所遭遇的障難而展開,其論述可分三個層面。

一、留難之必然與對治。佛告須菩提:「是甚深般若波羅蜜多有留難」,因此善男子、善女人若欲書寫般若波羅蜜,「應當疾書」;讀誦思惟說、正憶念、修行,「亦應疾修行」。其理由在於「不欲令諸難起故」。經中又以時間勉勵:若能一月書成當勤書,乃至二月、三月至一歲書成,亦當勤書;修行亦然,「若一月得成就乃至一歲得成就,應當勤成就」。佛更以「是珍寶中多有難起故」為喻,說明般若法門如珍寶般貴重而多難。

二、留難之來源與佛力護持。須菩提指出留難的根源:「惡魔憙作留難故,不得令書,不得令讀誦思惟說、正憶念、修行。」然而佛隨即說明,惡魔「雖欲留難是深般若波羅蜜」,「亦不能破壞是菩薩摩訶薩書般若波羅蜜乃至修行」。舍利弗追問誰力令魔不能留難,佛答以二重護持:一是「佛力故」,二是「十方國土現在諸佛力故」。十方無量無邊阿僧祇諸佛「擁護念是菩薩書深般若波羅蜜乃至修行,法應爾,亦無能作留難」。佛囑善男子、善女人當作是念:「我書是深般若波羅蜜乃至修行,皆是十方諸佛力。」舍利弗復確認:書是深般若乃至修行皆是佛力,「當知是人是諸佛所護」,佛印可之。

三、留難之辨識——似道法與遮道法。經中另以阿惟越致菩薩為例,展示留難的具體形態與辨識之道。魔「作比丘身來到菩薩所」,以「似道法」相誘——所謂似道法,即「三界繫」之世間行,包括骨相、初禪乃至非有想非無想等,勸菩薩取須陀洹果乃至阿羅漢果,言「汝今身取苦盡證」「汝用受生死中種種苦惱為」。阿惟越致菩薩「心不驚不疑不悔」,辨識此為似道法:「行是似道法,不至須陀洹果證,不得至阿羅漢、辟支佛道證,何況得至阿耨多羅三藐三菩提?」菩薩不但不受擾,反而「益復歡喜」,念言:「是比丘益我不少,為我說遮道法。我知是遮道法,是不遮學三乘道。」留難在此被轉化為辨識的資糧。

術語方面,本經以「留難」為核心用語,兼用「難」「諸難」;對魔所設虛偽修行另立「似道法」「遮道法」二專稱。經中又以「阿惟越致」(不退轉)稱不動於留難之菩薩,以「薩婆若」稱一切智,皆為鳩摩羅什譯本的特有用詞。
