This Concept Is About

At first glance, 究竟位 looks like a single rank: *the ultimate stage*. That is the most common reading, and it is precisely the one that causes most of the trouble. The 《瑜伽师地论》 (Yogācārabhūmi-śāstra) does not use 究竟位 as one fixed rung on a single ladder. It uses it as a *terminal marker* — the signature that a given line of cultivation has reached its furthest boundary, after which there is no further position to seek within that line.

The word 究竟 (atyanta) means "what cannot be pushed further, the extreme limit." 位 (avasthā) means "standing, state, position." Together: the state in which a process has reached its outer edge. The unifying structure across every appearance of this term is the same — a developmental arc has closed; the structural seeking for "the next step along that arc" quiets.

In the treatise, this marker is applied in at least five distinct domains. Each has its own criteria. Collapsing them into one is the first misreading to watch for.


1. In the seed-nature (种性): Ultimate as character-ripening

The treatise sets out four states of one's āśraya (种性, seed-nature / fundamental disposition): the impure (不清净位), pure (清净位), penetrated (通达位), and ultimate (究竟位). The ultimate is characterized by 安乐成满 — "fullness of ease/bliss" — and by surpassing three kinds of deterioration:

- 老死等变坏 — deterioration by aging, death, and the like - 颠倒处变坏 — deterioration by *places of reversal*, i.e., conditions under which wrong view regains a foothold - 清净退失变坏 — deterioration by *retrogression from achieved purity*

Its content is 一切烦恼自性离系离垢 — "all afflictions cut off and cleansed by their very nature" — surpassing the personality-view (萨迦耶见) and the wrong-view tendencies rooted in it. Here 究竟 is not a peak experience but a *non-retrogressing character*: the ripened state that does not decay back.

2. In meditation-and-insight (止观): Ultimate as dual cultivation *or* completed counteraction

Two forms appear:

- Dual-operating path (双运转道). After attaining the ninth of the nine mental abidings (三摩呬多, the perfected samādhi), and based on it cultivating superior wisdom, the practitioner reaches a state where through dharma-contemplation (法观) the path turns spontaneously, without effort. Vipaśyanā (毘钵舍那, insight) becomes pure and bright, and is absorbed in the pliancy of śamatha (奢摩他, calm-abiding). The two "和合、平等俱转" — operate in harmony and equality together. This is called the ultimate of the dual path.

- Completed counteraction (对治成办). In specific practices — impurity contemplation (不净观), loving-kindness (慈愍), dependent origination (缘性缘起), elemental analysis (界差别), breath-counting (阿那波那念) — the test is concrete. When the mind, exposed to objects that would feed greed, hatred, delusion, pride, mental searching (寻思), and entanglement (缠), exhibits a fivefold non-reaction — 心不趣入 (does not engage), 心不爱乐 (does not delight), 心不信解 (does not credit), 安住于舍 (abides in equanimity), 深生厌逆 (deeply recoils) — this too is called 已得究竟 ("attained ultimate").

3. In the bodhisattva ten grounds: Ultimate as the Dharma Cloud Ground (法云地)

The Dharma Cloud Ground is named 最上成满菩萨住 — "the most supremely accomplished bodhisattva abode." When bodhisattvas dwell here, all bodhisattva paths are complete, the provisions for awakening (菩提资粮) are perfectly prepared, and they can receive the most vast and subtle Dharma-rain that sentient beings find hard to receive. Its timetable is three countless great eons (三无数大劫) — a deliberately uncountable span: first eon to surpass the resolve-ground stage and reach the Joyous Ground; second eon to reach the Effortless, Functionless, Signless Ground; third eon to reach the supremely accomplished abode.

The decisive line is this: "升进,证得究竟,从此不求其余上地,已到究竟极边际故,名得无上" — "Advancing, one attains the ultimate; from here one does not seek any further ground, having reached the ultimate boundary, therefore called 'attained the supreme.'" The 究竟 marker here is the *cessation of structural seeking for higher grounds*, not the acquisition of an additional object.

4. In entering truth-realization (入谛现观): Ultimate as noble-learnerless knowledge and view

The treatise distinguishes:

- 智位 (wisdom-position): when entering truth-realization one truly knows the four noble truths - 见位 (view-position) - 现观位 (realization-position): at the noble-learnerless (无学) stage, one truly knows the four-fold formula — 我已遍知 (I have fully known), 我已永断 (I have permanently severed), 我已作证 (I have personally realized), 我已修习 (I have cultivated)

The 究竟智位 ("ultimate wisdom-position") is all the supreme liberation-wisdom encompassed by the noble-learnerless 尽智 (exhaustion-knowledge) and 无生智 (non-arising knowledge). The 究竟见位 ("ultimate view-position") is the right view produced by that wisdom. All learner-stage wisdom from stream-entry to the ultimate is subsumed under the realization-position. The final destination of all this is 于无余依般涅槃界而般涅槃 — parinirvāṇa with no remainder.

5. In training-completion: Six ultimate perfections *and* "initial-practice ground's ultimate completion"

Six kinds of ultimate completion (六种究竟圆满) are enumerated: (1) complete severance of afflictions and *all their habitual traces* (习气); (2) the four kinds of present-life blissful abiding (四种现法乐住); (3) complete worldly dhyāna liberation attainments; (4) free expression of Dharma through 名身 (name-body), 句身 (sentence-body), 文身 (syllable-body) at will; and so on.

A separate formulation — 始修业地究竟成满 — applies to the basic practitioner. A contemplator in the body-contemplation foundation (身念处), using true wisdom to penetrate dependent origination, enter the four-noble-truths wisdom, and generate weariness, dispassion, and liberation (厌患、离欲、解脱), has reached ultimate completion. The closing line is the starkest in the entire treatise: 一切自义皆已究竟,从此已后更无所作 — "All self-purposes have been ultimately completed; from here onward, nothing more is to be done."


What unifies the five

Despite their different criteria, all five share one structural signature: a process has reached the point where further advancement along that dimension is structurally unnecessary. Whether it is a character that no longer decays back, a meditation in which calm and insight run without being driven, a bodhisattva who no longer needs to seek higher grounds, an arhat who has completed the four-fold self-knowledge, or a contemplator whose self-purposes are fully done — in each case, 究竟 marks the *closing of a developmental arc*, not the *acquisition of an additional object*.

This matters. The same English word "ultimate" tempts us to imagine a single throne-room at the top of a single staircase. The Yogācārabhūmi shows 究竟 as a *type of marker* that legitimately attaches to multiple, partially independent trajectories of cultivation. Each has its own criteria, its own signs of completion, its own specific "nothing more to do." To be confused about which one is meant is to misread the term at the root.


Walking It Through in Contemporary Life

The five domains can each be walked through contemporary experience. None of them is about reaching the final stage; the value is in *recognizing which arc you are on* and *what its boundary looks like*, so you know when to stop seeking along that line and when seeking is still appropriate.


1. Seed-nature 究竟 — when your reactivity has changed at the root

Picture someone who for years flew into defensive rage at any hint of criticism. They noticed it, journaled about it, took a course, practiced pausing. None of those failed, none of them finished the work either. After enough time — and here we deliberately don't count the time — the rage simply doesn't appear. Not because they suppress it on the way up. They can still register criticism, still respond if response is needed. But the inner *flinch*, the heat behind the sternum, the rehearsed counter-attack — those don't come. That rough contemporary image approximates 烦恼自性离系离垢 — the affliction itself, by its nature, cut off.

Walking through the three deteriorations is more useful than chasing the goal:

- 老死变坏 — the practice works at 25 but breaks down at 55 under accumulated stress, illness, or grief. - 颠倒处变坏 — the practice holds on the meditation cushion or in the therapist's office but collapses at the office where your boss undermines your values. - 清净退失变坏 — you have tasted clarity, but a powerful event (a betrayal, a public failure, a death) erases it, and you are back at the start.

The seed-nature 究竟位 is when you have stopped oscillating among these. It is not perfection, and it is not stasis — but it is non-retrogression. *Easy and full* (安乐成满), not because nothing hurts, but because the rot has been cut at the level of the root.

A common mapping mistake here: people confuse "I no longer feel angry" with 究竟. They are not the same. The first can be dissociation, suppression, or simply a quieter nervous system. The classical mark is *the structural non-arising of the reactive pattern itself*, verified across the three forms of deterioration — not the absence of emotion.

2. Meditation-and-insight 究竟 — when concentration and insight no longer need you to drive them

Picture a daily sit, 30 minutes, for years. In the early months you fight to focus, then fight to stay loose, then notice the fighting, then fight the noticing. In time — and again, no clock — the mind settles and watches its own movements without you arranging it. You do not have to *choose* insight; the stability and the seeing support each other. That is 双运转道 — the dual path's 究竟.

The "completed counteraction" version is more pedestrian and more diagnostic. Pick one of the specific items the treatise names: gossip at work. The object *would feed* the affliction — in this case pride, contempt, the desire to belong by shared sneering. The classical test is the fivefold non-reaction. Walk it slowly:

- 心不趣入 — the mind does not move *toward* the object. Not "I notice but push away" — it does not even move toward it. - 心不爱乐 — it does not find the object sweet. There is no pleasure in the taking. - 心不信解 — it does not credit the object's implicit claims. "She's terrible" registers as a sentence, not as a fact. - 安住于舍 — it rests in equanimity. Not detached in a cool way; resting in a wide, clear way. - 深生厌逆 — it deeply recoils. Not angrily; with a deep, clean *no thank you*.

When all five are present for a specific class of objects, the practitioner has "attained ultimate" within that counteraction. The 究竟 is *local*, in other words — it attaches to a specific practice, a specific class of objects, a specific reactive pattern. It does not claim global accomplishment.

A mapping mistake to watch for: people read "心不趣入" as "I don't care anymore." That is not what the text says. Equanimity (舍) is not indifference; it is a stance of clear seeing that no longer takes the bait. The classical image is not a closed fist — it is open eyes that are not hungry.

3. Bodhisattva 法云地 究竟 — a horizon, not a checklist

For a contemporary reader this domain is mostly a horizon. The signal is the *opposite* of self-help optimization: bodhisattva preparation is not the acquisition of more skills but the ripening in which the work of helping others no longer requires strategic self-calculation. The "Dharma-rain" image is the giveaway — someone so prepared that difficult teachings land on them without damage.

The phrase that matters most for a contemporary audience is "从此不求其余上地" — *from here, does not seek other higher grounds*. This is not burnout-quitting, and it is not nihilistic disengagement. It is the structural quieting of the drive to *climb*. Many contemporary people experience endless self-improvement as a form of inner restlessness; the 究竟 marker names what its structural opposite looks like, even if that opposite is reached only after a "three countless great eons" of preparation.

Mapping mistake: reading the Dharma Cloud Ground as "the highest achievement" in a competitive ranking. The treatise is not arranging grades. It is naming the point at which the bodhisattva stops needing to seek ranks — and is therefore free to receive, rather than to climb.

4. Noble-learnerless 究竟 — when the training has ended, not because you stopped

The four-fold formula — 我已遍知、我已永断、我已作证、我已修习 — is one of the most precise pieces of self-knowledge-language in the Buddhist tradition. Walk each one:

- 我已遍知 — *I have fully known*. Not "I know everything," but "I have completed the knowing of what was to be known." The scope is bounded. - 我已永断 — *I have permanently severed*. Not "I have broken every habit," but "the work of severing what was to be severed is done." - 我已作证 — *I have personally realized*. Verified from the inside, not on authority. Not on a teacher's nod. - 我已修习 — *I have cultivated*. The cultivation itself has reached its completion — meaning the *need* to cultivate as a project is over.

A contemporary analogue — and note the limit of the analogy — is the moment in any deep practice (a craft, a sport, a therapeutic path) when you no longer need the framework to perform the act. The framework doesn't get discarded out of rebellion or boredom; it falls away because you have embodied it. You don't need to remind yourself of the rule because the rule is now what you do.

Mapping mistake: people sometimes translate 遍知 as "omniscient." The treatise does not say that. It says *fully known* — known through and through — within the scope of what was to be known (the four truths, in this context). The container matters.

5. Initial-practice-ground 究竟 — when the basic work has truly been done

This is the formulation most accessible to a contemporary reader. Picture someone who has been in therapy for years on a specific wound — an absent parent, a public humiliation, a chronic comparison — and one day they realize the wound is no longer the center of their days. Not that nothing hurts; not that the wound vanishes in conversation. But the 自义 (self-purpose) of dealing with that specific work is done. The opening line of the practitioner's experience has shifted.

The closing line of the treatise then lands: "一切自义皆已究竟,从此已后更无所作" — *all self-purposes have been ultimately completed; from here onward, nothing more is to be done*.

This is striking because in a culture that demands constant productivity and self-optimization, the idea that a piece of inner work could legitimately be *done* — and that the practitioner is *not* failing by stopping — is countercultural. The 究竟 marker here gives linguistic and conceptual permission for an arc to close.

Mapping mistake: reading "更无所作" as "go lie down." "Nothing more to be done" refers to the *self-project* of working on that particular purpose, not to all activity. In the bodhisattva case, the activity *increases* after 究竟 is reached — receiving the Dharma-rain, helping others — because the seeking has quieted and the activity can flow without the structural drive to climb. Cessation of seeking is not cessation of action.


Why Contemporary People Need This Concept

1. It gives language to completion, which our culture systematically denies.

Modern life is built on endless optimization: career, relationships, health, identity, inner life — all framed as ongoing projects with quarterly KPIs. The classical 究竟位 says that some processes have a proper endpoint, and that endpoint is *not* more of the same. Recognizing the endpoint, in any domain where it actually exists, is a skill.

2. It saves us from two opposite errors — and gives us a way to distinguish them.

(a) Settling prematurely. "I'm done with this" when only the surface has been smoothed. (b) Endlessly seeking. "I'm never done enough" when the structural work is genuinely complete. The five domains give us five *distinct* tests of completion. We can ask, in any given pursuit: along *which* dimension has my work reached its boundary, and which tests — the three deteriorations, the dual path's effortless operation, the four-fold self-knowledge — am I actually meeting?

3. It locates "I have finished" within a verifiable structure, not a feeling.

"I have fully known / severed / realized / cultivated" are *four distinct verifications*, not one mood of accomplishment. This is precious for people trained — by meditation culture, by therapy culture, by self-help culture — to distrust their own experience. The 究竟 marker offers specific checkpoints, not a vibe.

4. It distinguishes 究竟 from 无学, and that distinction matters.

无学地 (noble-learnerless ground) is a specific stage on a specific path. 究竟位 is a *type of marker* that can attach to multiple stages, including seed-nature maturation, the dual-cultivation path, the bodhisattva's Dharma Cloud Ground, and the noble-learnerless attainment. Saying "I've reached 究竟位" without specifying *which* is a category error — like saying "I've reached the limit" without saying of what.

5. It pairs attainment with *the cessation of seeking*, which is psychologically radical.

"从此不求其余上地" — *from here does not seek further grounds* — is not "I've reached the top"; it is *the seeking itself quiets*. Many contemporary people experience endless self-improvement as a form of inner restlessness; the 究竟 marker names what its structural opposite looks like, in language that does not require us to first reach it.

6. It pairs individual completion with collective and pedagogical dimensions.

The "six ultimate perfections" explicitly include free expression of Dharma through name, sentence, and syllable — i.e., the ability to teach accurately when needed. 究竟 is not only introspective; it has communicative and pedagogical dimensions. A practitioner at the boundary is not silent — they are now fluent enough to articulate, when the conditions call for it. This counters the contemporary picture of awakening as a private, incommunicable glow.


Common Misreadings and Clarifications

Misreading 1 — "究竟位 is a single fixed rank."

Clarification: It is applied in five domains in the Yogācārabhūmi alone. Each has its own criteria. To ask "have you reached 究竟位?" without specifying *which* 究竟位 is a category error, not a question.

Misreading 2 — "究竟 means perfect in every dimension."

Clarification: 究竟位 is *terminal within a specific dimension*. A bodhisattva at the Dharma Cloud Ground may have supreme provisions but is still within the bodhisattva's ongoing life. A noble-learnerless arhat has fully known, severed, realized, and cultivated *the four noble truths*, not every conceivable object. The boundary is contained.

Misreading 3 — "究竟 means it's time to coast."

Clarification: "从此已后更无所作" refers to the *structural seeking*, not to all activity. In the bodhisattva case, the activity *expands* after 究竟 is reached — receiving the vast Dharma-rain, helping others, articulating the teaching. The "no more to do" is about the self-project of climbing, not about doing nothing.

Misreading 4 — "究竟 equals nirvana."

Clarification: Only contexts 4 and 5 explicitly tie 究竟 to nirvāṇa / cessation. Context 1 emphasizes non-retrogression; context 2 emphasizes effortless operation; context 3 emphasizes the cessation of seeking higher grounds. The same word does different work in different chapters. Reducing it to nirvana alone cuts off four of the five applications.

Misreading 5 — "究竟位 and 无学位 are the same."

Clarification: They are tightly linked (context 4 shows 究竟智位/究竟见位 *emerge from* the noble-learnerless level), but they are not identical. 无学地 is a specific stage on a specific path. 究竟位 is a *type of marker* that can attach to multiple stages. They overlap, but neither contains the other.

Misreading 6 — "心不趣入 (the mind does not engage) means 'I've stopped caring.'"

Clarification: The full fivefold formula — 不趣入、不爱乐、不信解、安住于舍、深生厌逆 — is *active*, not passive. The mind does not engage, does not delight, does not credit, abides in equanimity, *and deeply recoils*. Equanimity here is clear seeing, not numbness. The classical image is not a closed fist; it is open eyes that are not hungry.

Misreading 7 — "究竟 is a one-time peak experience."

Clarification: The seed-nature description explicitly names 清净退失变坏 — retrogression from achieved purity — as one of the three deteriorations 究竟位 must surpass. 究竟 is therefore a *stable state* whose stability is precisely what distinguishes it from momentary peaks. If it can be lost under the right pressure, it has not been reached. If it cannot be lost — across aging, across reversal, across the seductions of the world — the marker has been met.

Misreading 8 — "We've all basically always been at 究竟."

Clarification: This is a common contemporary move — universalizing the goal so no work is required. The five-domain structure of the Yogācārabhūmi is the rebuttal. Each domain has *specific tests*: passing the three deteriorations, sustaining the fivefold non-reaction across a class of objects, completing three countless great eons of bodhisattva preparation, articulating the four-fold self-knowledge from the inside, generating weariness/dispassion/liberation in the body-contemplation foundation. These are not metaphors; they are specifications. To claim 究竟 without meeting specifications is not humility — it is a misreading of the term.


A Final Note on Use

What 究竟位 gives a contemporary reader is not a destination to rush toward. It is a *grammar of completion*: a way to ask, in any line of practice, *what would it look like for this arc to actually close?* Not "have I done enough?" but "what is the specific structural signature of *this particular arc* reaching its boundary?"

The Yogācārabhūmi offers five such signatures, in five distinct domains. Holding them as five — and resisting the temptation to merge them into one — is itself a piece of the practice.

Canonical EntryAI-generated

1. 定义与核心要义

「究竟位」(atyantāvasthā)在《瑜伽师地论》中,不仅指单一而固定的阶位,也用来标示各种修行体系达到圆满、极边际或更无所作的状态。其核心要义随所论对象而异:就种性而言,是烦恼离系离垢而安乐成满;就止观而言,是奢摩他与毵钵舍那平等俱转,或特定观行已能令心远离相应烦恼;就菩萨道而言,是法云地中菩萨道及菩提资粮的最上成满;就声闻现观而言,则是无学位尽智、无生智及极解脱智的圆成。故「究竟」共同表示某一修行进程已经达到其最高边际,不再另求上位。

2. 主要阐述

第一,种性相分为不清净位、清净位、通达位与究竟位四位。究竟位以「安乐成满」为相,并超过三种变坏:老死等变坏、颠倒处变坏及清净退失变坏。其内涵是一切烦恼自性离系离垢,超过萨迦耶见以及以此为根本的诸恶见趣。此处的究竟着重烦恼根本断离后所得的不退坏与成满。

第二,在止观修习中,究竟具有可辨认的行相。修行者先得九相心住中的第九相心住,以圆满三摩地为依而修增上慧;由法观之力,道能任运而转、无须功用,毵钵舍那清净鲜白,并受奢摩他调柔摄持。奢摩他与毵钵舍那和合、平等俱转,称为「双运转道」之究竟。又修不净观、慈愍、缘性缘起、界差别、阿那波那念等时,面对能随顺贪、瞋、痴、慢、寻思及缠的境法,若心不趣入、不爱乐、不信解,安住于舍而深生厌逆,亦称「已得究竟」。前者侧重止观双运,后者侧重观行对治已经成办。

第三,菩萨十地以法云地为「最上成满菩萨住」。住此地时,诸菩萨道圆满,菩提资粮极善周备,并能领受有情难以领受的最极广大微妙法雨。其进程以三无数大劫说明:第一无数大劫超过胜解行住而证极欢喜住;第二无数大劫证无加行无功用无相住;第三无数大劫证最上成满菩萨住。菩萨至此已到究竟极边际,不再求其余上地,因而名为「得无上」。

第四,在谛现观体系中,入谛现观而如实了知四圣谛,称为智位;至无学地,如实了知「我已遍知、我已永断、我已作证、我已修习」,称为现观位。无学尽智、无生智所摄的一切极解脱智,名究竟智位;由无学极解脱智所引的正见,名究竟见位。从预流果直至究竟,其间一切学慧则摄于现观位。此一进程的终极归趣,是于无余依般涅槃界而般涅槃。

第五,论中又从所成功德说明六种究竟圆满,包括烦恼及习气无余离系、四种现法乐住、世间静虑解脱等持等至,以及名身、句身、文身随欲宣说正法等方面的究竟圆满。另说「始修业地究竟成满」:观行者于身念处中,以如实慧通达缘起、入四圣谛智,并生起厌患、离欲、解脱,即名究竟成满;至此一切自义已办,此后更无所作。

3. 不同部类与译本的表述差异

现有材料仅涉及瑜伽部《瑜伽师地论》(《瑜伽師地論》),未提供其他部类经典或同经异译,故不能据此列举跨部类、异译本之间的词语分歧。就本论内部而言,其表述随论域而变:种性相中称「究竟位」,以安乐成满、超过三种变坏为义;止观门中称「双运转道」或「已得究竟」;菩萨地中称「最上成满菩萨住」「究竟极边际」及「得无上」;现观门中分称「究竟智位」「究竟见位」;功德修满处则称「究竟圆满」或「究竟成满」。这些名称分别对应种性、观行、菩萨住、无学智慧与修习功德,并非原文中的同一套阶位名称。

4. 与相关概念的关系

「究竟位」与「无学地」相联时,着重尽智、无生智、极解脱智及其所引正见;与「无余依般涅槃界」相联时,表示究竟解脱的最终归趣。

它与「奢摩他」「毵钵舍那」的关系,是止与观在圆满三摩地及增上慧的基础上和合、平等俱转;因此止观双运是观行门中究竟的一种明确形态。

它与「法云地」的关系,是法云地被称为最上成满菩萨住,标志菩萨道及菩提资粮圆满,并已到不求其余上地的极边际。

它与「离系」「离垢」「离欲」「解脱」相通而侧重点有别:种性究竟强调烦恼自性离系离垢;六种圆满又兼举烦恼及习气无余离系;始修业地的究竟成满则依次表现为通达缘起、入四圣谛智、厌患、离欲与解脱。

5. 代表性原文引用

种性相之究竟,可概括为:「安乐成满」及「超过三种变坏」;其所断离者为「一切烦恼自性离系离垢」。

止观之究竟,原文以「奢摩他、毵钵舍那二种和合平等俱转」说明双运转道;对治成办时,则说「心不趣入、心不爱乐、心不信解、安住于舍、深生厌逆」。

菩萨地的极处称:「升进,证得究竟,从此不求其余上地,已到究竟极边际故,名得无上。」

无学现观的自证表述为:「我已遍知、我已永断、我已作证、我已修习。」

修行所作圆成,则以「一切自义皆已究竟,从此已后更无所作」表示其不可再增的完成状态。

瑜伽師地論T1579 · 瑜伽部

《瑜伽師地論》以「四位」架構安立修行階次,究竟位為其最極。論中明言:「復由四位、九相,應知種性相。何等四位?一、不清淨位,二、清淨位,三、通達位,四、究竟位。」 四位之中,不清淨位「於一切相等隨行故,譬如虛空」;清淨位「平等一味,及身心遠離」;通達位「隨順趣究竟」;究竟位則以「安樂成滿,及超過三種變壞」為其九相中之二相。 此處「種性相」被界定為「無學界相」,亦即究竟位所攝乃無學聖者之境界,非有學所能預。

究竟位之核心內涵,論以「超過」一詞反覆標示。所謂三種變壞——「一者、老死等變壞,二者、顛倒處變壞,三者、清淨退失變壞」——涵蓋生死流轉之根本苦患、邪見顛倒之迷謬、以及已得清淨復退失之虞;究竟位悉皆超過,無復退轉。論又就現法、後法二門廣說超過之事:現法中超過所作、非所作、所作加行、所作非加行、非所作加行五事;後法中超過能發起後有行、彼行、彼果生、依彼衰盛、修學期願受用、彼所依自體差別六事。 此中「超過」非僅暫伏,乃永離繫縛,與「一切煩惱自性離繫離垢」之通達位相銜接而更進一層——通達位已「超過薩迦耶見,及超過彼為根本諸惡見趣」,究竟位則連老死變壞、清淨退失亦悉超過,安樂圓滿成辦。

另一處論及漸次修行趣入究竟之歷程:行者「漸次修行,後後轉勝、轉增、轉上,修集諸緣,初自圓滿,依三摩地以為最後」,心得「清淨鮮白,無諸瑕穢,離隨煩惱,質直堪能,安住無動」。 此段以三摩地為修行最後所依,心達鮮白無動方為堪任入道之器。既得此心,復「獲得依四聖諦,為令遍知、永斷、作證、修習他音教授教誡」,由此「發生如理所引作意,及彼為先所有正見」,終能「於四聖諦入真現觀,圓滿解脫,於無餘依般涅槃界而般涅槃」。 此即究竟位之實證內容:以四聖諦之遍知、永斷、作證、修習為綱骨,以「真現觀」為能入之智,以「圓滿解脫」與「無餘依般涅槃界而般涅槃」為所證之果。

就術語形式而言,本論特用「究竟位」與「通達位」對舉,以「位」標階次;又以「種性相」統攝四位九相,將究竟位歸於「無學界相」。 論中不單說「究竟」為形容詞,而將之立為一獨立之「位」,與不清淨、清淨、通達三位並列,此為本論階次安立之獨特用語。又「安樂成滿」一語為本論描述究竟位果德之專有表述,強調非僅離苦,乃安樂之積極圓滿。 而「超過三種變壞」之說,以否定式(超過)界定究竟,亦為本論特色。

此位之修行核心,在於菩薩對佛所善成立之一切妙法作「總聚緣」——即以佛一切妙法為總聚之緣境。其下手處為「心根安法界」,意謂入第一義智,令心以慧安住於法界;心既安住法界,故此心名為「根」。其後復起觀行,「解念唯分別」,於念轉之處解知諸念唯是分別、非實有;其果則「速窮功德海」,能速達於佛果功德海之彼岸。

偈頌另標究竟位之成就相:「二聚界圓滿,果起依最上,世間得第一,說力成熟相」。二聚之界已得圓滿,果起依於最上,世間得為第一,乃「說力成熟」之相。

就時劫與階位言之,究竟位之成就須歷二僧祇劫——即第二、第三大劫阿僧祇——之修習;至「究竟修」位方「得受職」。受職已後,更「入彼金剛定,破諸分別盡」。此定之所以名「金剛」,在於「分別隨眠此能破故」——能破一切分別之隨眠,故以金剛喻其堅利能斷,此定因亦稱「金剛喻定」。

究竟位之究竟果相,復以偈頌詳顯之:「成就第一義,出離一切地,於他得尊極,解脫諸眾生,無盡等功德,現在皆具足,世見眾亦見,不見人天等」。其中「成就第一義」即「心根安法界」「入第一義智」之究竟果;「出離一切地」顯已超菩薩諸地;「於他得尊極」即「受職」之果;「解脫諸眾生」顯大悲之究竟;「無盡等功德現在皆具足」謂自他無盡功德一時具足;「世見眾亦見,不見人天等」明此位為世所共見,其深廣則非人天所能測。

綜觀此論,究竟位之論述可歸三端:一、以「總聚緣」「第一義智」「心根安法界」「解念唯分別」「速窮功德海」明其觀行與斷證之核心;二、以「二僧祇」「究竟修」「受職」「金剛定」「金剛喻定」「分別隨眠」標其時劫階位與破惑之歷程;三、以「成就第一義」「出離一切地」「於他得尊極」「解脫諸眾生」「無盡功德具足」明其究竟果相。

就術語特色而言,此論所用「金剛定」「金剛喻定」二名並用,前者就定體而立,後者就破惑力用而立;「受職」一詞為本論描述究竟位之專名,與其他經論或但云「成佛」「成正覺」者用詞不同,特指登正等覺位、堪紹佛職之莊嚴受命。
