Why a Buddha's Eighteen Distinctive Dharmas and Four Analytical Knowledges Are the Completeness and Unobstructedness of the "Function" of Mastery, Not Superpowers Acquired Beyond the Severing of Defilements and the Turning into Wisdom

中文主題：如來十八不共法與四無礙解——佛之十八不共四無礙何以是自在之「用」之圓滿與無礙，而非斷惑成智之外別得之超能力

I. The Question

Part 4 sets down the buddha-fruit's "function of mastery." The prior paper (P05) took the first two of the Avataṃsaka's "Tathāgata's masterful function" cluster — the ten powers and four fearlessnesses — and established them as "knowledge-powers" and "the fearlessness disclosed by the completeness of wisdom-and-severance," both the already-established mastery turned toward beings as function, not superpowers acquired beyond severing the defilements and turning into wisdom. This paper takes up the baton and the remaining two of the same cluster — the eighteen distinctive dharmas and the four analytical knowledges — and asks the same question: a Buddha's eighteen distinctive dharmas and four analytical knowledges — what are they?

The question presses because of an imagination this series has broken five times over, yet which recurs at each new topic. The series has repeatedly broken the picture that "the buddha-fruit's virtues are something acquired beyond the severing of defilements": the exhaustion of taints is mastery (the Arhat division); the ten epithets are a signature, not acquired virtues (P01); the fruit-level is not the causal-level brightened (P02); the three bodies are one mastery's manifestation, not three Buddhas (P03); the four wisdoms are turned from the eight consciousnesses, not acquired spiritual cognitions (P04); the ten powers are knowledge-powers and the four fearlessnesses the fearlessness of completeness, not acquired superpowers (P05). Arrived at the "eighteen distinctive dharmas" and "four analytical knowledges," the same temptation recurs in the guise of "one more batch added": to suppose that, beyond the four wisdoms, ten powers, and four fearlessnesses, a Buddha further trains up "eighteen capacities possessed by a Buddha alone" and "four kinds of eloquence-power" — as if, after name, body, wisdom, powers, and fearlessnesses, a Buddha went elsewhere to fetch a "sixth batch of treasures."

This paper holds the picture still misplaced, and holds that the establishment of these two most clearly shows "function" to be not "acquired." First, the eighteen distinctive dharmas are not eighteen capacities a Buddha acquires, but the "self-benefiting completeness" aspect of the already-established mastery. Looking at the full list (§II), not one of the eighteen is "one newly acquired capacity"; all are aspects of "non- · following · unobstructed": the three "non-lapses" of action (body · speech · mindfulness without lapse), the six "non-diminutions" (zeal · vigor · mindfulness · wisdom · liberation · the knowing-and-seeing of liberation), the three actions "following wisdom," and the three-times knowledge "unobstructed." "Non-lapse," "non-diminution" are privative terms — not "acquiring a non-lapse," but "in the already-complete three actions and six dharmas, no further lapse or diminution"; "following wisdom" is a term of conformity — not "acquiring a wisdom-following capacity," but "the already-established three actions all turn following the already-established wisdom"; "the three-times knowledge unobstructed" is precisely the prior paper's ten powers (the all-kinds wisdom's knowing-as-it-is across ten domains) said, with respect to the three times, as "unhindered." So the eighteen distinctive dharmas are the same mastery (the four wisdoms · the virtue of severance) disclosed under "non-lapse · non-diminution · following wisdom · unobstructed" — the aspect of completeness, not eighteen things added beyond completeness. Second, the four analytical knowledges are not four kinds of eloquence a Buddha acquires, but the "other-benefiting unobstructedness" aspect of the same mastery. The four unobstructed knowings of meaning, dharma, expression, and eloquence the treatise closes as "penetrating these four matters without impediment is called unobstructed knowing" — the unobstructed being "penetration without impediment"; the four analytical knowledges are the aspect of the "unobstructed" knowing (the prior paper's ten-powers / three-times-unobstructed knowing) expounding and delivering beings before the assembly. They are the already-established mastery's "speaking" turned toward beings without impediment, not four capacities acquired apart from speaking.

This carries forward the Attainment axis's one constant frame, and, with the prior paper, fills one heading. This series holds the buddha-fruit's virtues all to be aspects of "turning / severing / manifesting," not things "acquired from outside": name (the ten epithets) · body (the three bodies) · wisdom (the four wisdoms) all so; the prior paper supplied the first half of the "function" heading (the ten powers and four fearlessnesses). This paper supplies the latter half: the eighteen distinctive dharmas are the "function" in its self-benefiting completeness aspect, the four analytical knowledges the "function" in its other-benefiting unobstructedness aspect. So the axis's frame has all four headings complete — name · body · wisdom · function — and the "function" heading is jointly established by the four dharmas of Part 4 (P05 · P06): the ten powers · four fearlessnesses · eighteen distinctive dharmas · four analytical knowledges, which the Avataṃsaka's verse lists together and names outright "the Tathāgata's masterful function." And this division's keynote of "unobstructed mastery" (apratihata) is densest in this paper: the eighteen distinctive dharmas' last three, "the wisdom knowing the three times unobstructed," and the four analytical knowledges' "four unobstructed knowings" — the word "unobstructed" enters the names of the fruition-virtues in two places, the keynote self-disclosing.

This paper rests, as before, on the Dazhidu lun (the treatise pivot) and the eighty-fascicle Avataṃsaka (the verse witness of their joint listing). The argument runs in three moves (§III): the eighteen distinctive dharmas are the aspect of self-benefiting completeness ("non- · following · unobstructed"), not eighteen acquired capacities (3.1); the four analytical knowledges are the aspect of other-benefiting unobstructedness (exposition penetrating without impediment), i.e. "unobstructedness" turned toward beings as exposition (3.2); the eighteen distinctive dharmas and four analytical knowledges, with the ten powers and four fearlessnesses, fill the "function" heading — the eighteen distinctive dharmas disclosing function's completeness, the four analytical knowledges its opening-out, the import of both being to deliver beings (3.3). Section IV cuts the interdisciplinary convergence (rationale in §VI). Section V offers middle-way corrections and marks two adjudications reserved to the author (the discrimination of "distinctive," and the stage-and-knowing assignment of the four analytical knowledges). Section VI concludes and hands the marks and signs (the form-body's mastery-signature) to P07, the great compassion and all-kinds wisdom to P08, the Tathāgata's ten masteries and permanence-bliss-self-purity to P09, and the ultimate non-abiding nirvāṇa to P10.

II. The Canonical Basis

2.1 The eighteen distinctive dharmas in full: aspects of "non- · following · unobstructed," and the discrimination of "distinctive"

The treatise pivot for the eighteen distinctive dharmas is in the Dazhidu lun, fascicle 26, the "Exposition of the Eighteen Distinctive Dharmas." The treatise lists them one by one:

十八不共法者：一者、諸佛身無失，二者、口無失，三者、念無失；四者、無異想，五者、無不定心，六者、無不知已捨；七者、欲無減，八者、精進無減，九者、念無減，十者、慧無減，十一者、解脫無減，十二者、解脫知見無減；十三者、一切身業隨智慧行，十四者、一切口業隨智慧行，十五者、一切意業隨智慧行；十六者、智慧知過去世無礙，十七者、智慧知未來世無礙，十八者、智慧知現在世無礙。¹

"The eighteen distinctive dharmas: first, the buddhas' bodily action without lapse; second, speech without lapse; third, mindfulness without lapse; fourth, no errant ideation; fifth, no unconcentrated mind; sixth, no inattentive equanimity; seventh, zeal without diminution; eighth, vigor without diminution; ninth, mindfulness without diminution; tenth, wisdom without diminution; eleventh, liberation without diminution; twelfth, the knowing-and-seeing of liberation without diminution; thirteenth, all bodily action following wisdom; fourteenth, all verbal action following wisdom; fifteenth, all mental action following wisdom; sixteenth, the wisdom knowing the past unobstructed; seventeenth, the wisdom knowing the future unobstructed; eighteenth, the wisdom knowing the present unobstructed."

The eighteen are well ordered, falling into groups: (1) the three non-lapses (body · speech · mindfulness without lapse); (2) no errant ideation · no unconcentrated mind · no inattentive equanimity (the three marks of a mind free of scattering and admixture); (3) the six non-diminutions (zeal · vigor · mindfulness · wisdom · liberation · the knowing-and-seeing of liberation); (4) the three actions following wisdom (bodily, verbal, mental action all turning following wisdom); (5) the three-times knowledge unobstructed (the wisdom knowing past · future · present unobstructed). Especially to be marked: not one of the eighteen is "one newly acquired capacity"; all are terms of privation (non-lapse · non-diminution), of conformity (following wisdom), and of non-hindrance (unobstructed). "Non-lapse" is not the acquiring of "a capacity of not lapsing," but that in the buddhas' already-complete three actions of body, speech, and mindfulness no further fault is to be found; "non-diminution" is not the acquiring of "a capacity of not diminishing," but that in the already-possessed six dharmas of zeal, vigor, mindfulness, wisdom, liberation, and the knowing-and-seeing of liberation there is ever no regress or decline; "following wisdom" is not the acquiring of "a wisdom-following capacity," but that the buddha's three actions all turn following the already-established wisdom (the four wisdoms, P04), no action escaping wisdom; and the sixteenth through eighteenth, "the wisdom knowing the three times unobstructed," are precisely the prior paper's ten powers (the all-kinds wisdom's knowing-as-it-is across ten domains) said, with respect to the three times, as "unhindered" — "unobstructed" entering the names of the distinctive dharmas, the same brushstroke as the "unobstructed knowing of the divine eye · of past lives" within the ten powers (P05, §2.1): the buddha's knowing is distinctive precisely in being "unhindered." So the eighteen distinctive dharmas are the same buddha-ground's virtue of wisdom and virtue of severance, disclosed under the four aspects of "non-lapse · non-diminution · following wisdom · unobstructed" as self-benefiting completeness.

The treatise further raises a self-set question to discriminate the sense of "distinctive" — why these eighteen alone are named "distinctive":

問曰：是三十六法，皆是佛法，何以故獨以十八為「不共」？答曰：前十八中，聲聞、辟支佛有分，於後十八中無分。²

"Question: These thirty-six dharmas are all dharmas of a Buddha; why are only the eighteen taken as 'distinctive'? Answer: In the former eighteen the śrāvaka and pratyekabuddha have a share; in the latter eighteen they have no share."

The treatise-master discriminates by "former eighteen / latter eighteen": in the latter eighteen (these eighteen distinctive dharmas) the śrāvaka and pratyekabuddha have no share, and so these alone are named "distinctive" (not shared with the two vehicles). This discrimination is recorded here as the treatise's own statement; what it establishes is "the buddha-ground's distinctive fruition-virtues" — the sense that only the buddha-fruit completely possesses these eighteen dharmas. It must be marked with all seriousness: the precise extent of this "distinctiveness" (where exactly the two vehicles have a share and where they have none), its relation to the bodhisattva's causal level, and the convergence of "distinctive" with this series' bodhisattva-division frame of "heteromorphic, not hierarchically superior" (異質而非高下), are all major cross-axis adjudications; this paper records the treatise without adjudicating in the author's stead, leaving all of it to the author and to cross-axis convergence (see §V, Correction 2). This paper takes from it only the one sense: the eighteen distinctive dharmas are the aspect of the buddha-ground's completeness (showing them to be fruit-level complete, not acquired capacities).

2.2 The four analytical knowledges in full: penetration without impediment is called "unobstructed knowing"

The treatise establishment of the four analytical knowledges is in the Dazhidu lun, fascicle 25 (at the close of the chapter on the four fearlessnesses, continuing with the four unobstructed knowings). The treatise lists the four of meaning, dharma, expression, and eloquence, expounding them with "earth" as its example:

「四無礙智」者：義無礙智、法無礙智、辭無礙智、樂說無礙智。「義無礙智」者……此中地堅相是「義」，地名字是「法」，以言語說地是「辭」，於三種智中樂說自在是「樂說」；於此四事中通達無滯，是名「無礙智」。³

"The 'four unobstructed knowings': the unobstructed knowing of meaning, the unobstructed knowing of dharma, the unobstructed knowing of expression, the unobstructed knowing of eloquence. As for the unobstructed knowing of meaning… Here earth's solid mark is the 'meaning,' earth's name is the 'dharma,' speaking of earth in language is the 'expression,' and mastery in expounding among the three knowings is 'eloquence'; penetrating these four matters without impediment is called 'unobstructed knowing.'"

The four analytical knowledges (catur-pratisaṃvid) are the four unobstructed knowings of meaning, dharma, expression, and eloquence. The treatise's example of "earth" is most plain: earth's solid mark (the meaning signified) is what the unobstructed knowing of meaning bears upon; earth's name (the signifying name) is what the unobstructed knowing of dharma bears upon; the speaking of this earth in language (the expressing speech) is what the unobstructed knowing of expression bears upon; and the masterful, responsive expounding among the former three knowings is the unobstructed knowing of eloquence. The treatise closes, "penetrating these four matters without impediment is called unobstructed knowing" — the precise gloss of "unobstructed" being "penetration without impediment": penetrating the four matters of meaning, dharma, expression, and eloquence without any impediment. So the four analytical knowledges are not four kinds of eloquence-power acquired separately, but the aspect, when the "unobstructed" knowing (the prior paper's ten-powers / three-times-unobstructed knowing) teaches and delivers beings, of penetrating without impediment the four matters of the meaning signified, the dharma signifying, the speech expressing, and the responsive eloquence. The Chinese rendering "the unobstructed knowing of eloquence" (樂說無礙) is what other treatises commonly call "the unobstructedness of eloquence" (辯無礙) — a small difference of rendering, the referent one.

The treatise further marks that the four unobstructed knowings differ in the stage on which they rest and the knowing they comprise, recorded here as follows:

第一、第四無礙智，在九地中；第二、第三無礙智，在欲界及梵天上。第二、第三無礙：世智。第一：十智。第四：九智。⁴

"The first and fourth unobstructed knowings are within the nine stages; the second and third unobstructed knowings are in the desire realm and the Brahmā heavens. The second and third unobstructed: worldly knowing. The first: the ten knowings. The fourth: the nine knowings."

The treatise marks that the first (meaning) and fourth (eloquence) unobstructed knowings are within the nine stages, the second (dharma) and third (expression) in the desire realm and the Brahmā heavens; and, as to the knowing comprised, the second and third are worldly knowing, the first comprises the ten knowings, the fourth the nine knowings. This is the treatise's stage-and-knowing statement about the four unobstructed knowings, recorded for its detail. Yet the treatises variously hold the four analytical knowledges' resting-stage, comprised knowing, and subject-object assignment (and this passage expounds the four analytical knowledges in their general sense, inclusive of the causal level, while the buddha-ground's perfection of the four has its own establishment); this paper records the Dazhidu lun's own text without harmonizing among the several positions in the author's stead, and puts no verdict on the boundary between "causal-level four analytical knowledges" and "buddha-ground four analytical knowledges" (see §V, Correction 3). This paper takes from it only the one sense: the substance of the unobstructed knowings is the "unobstructedness" of "penetration without impediment" — precisely this division's keynote of "unobstructed mastery" turned toward beings in exposition.

2.3 The import of their joint listing: the eighteen distinctive dharmas, with the ten powers and fearlessnesses, are "the Tathāgata's masterful function"

When the eighteen distinctive dharmas are listed together with the ten powers and four fearlessnesses, the eighty-fascicle Avataṃsaka, in a verse of fascicle 14, comprises them outright as "the Tathāgata's masterful function" (the prior paper cited this verse to establish the import of the ten powers and four fearlessnesses; this paper cites it again to establish the import of the eighteen distinctive dharmas):

如來十力無所畏，及以十八不共法，所有無量諸功德，悉以示現度眾生。記心教誡及神足，悉是如來自在用，彼諸大士皆示現，能使眾生盡調伏。⁵

"The Tathāgata's ten powers and fearlessnesses, together with the eighteen distinctive dharmas, and all the measureless virtues — all are manifested to deliver beings. Knowing-minds, instructing, and the supernormal feet — all are the Tathāgata's masterful function; those great beings all manifest them, able to bring beings wholly to be tamed."

The verse lists the four — "the ten powers · fearlessnesses · eighteen distinctive dharmas · measureless virtues" — together, and their function is "all manifested to deliver beings"; it further marks "knowing-minds, instructing, the supernormal feet… all the Tathāgata's masterful function." The four characters "the Tathāgata's mastery" present themselves on the face of the scripture: the eighteen distinctive dharmas (with the ten powers and four fearlessnesses) are not an isolated inventory of capacities, but the "function" of "the Tathāgata's mastery," the import of whose operation is "to deliver beings," "to bring beings wholly to be tamed." The eighteen distinctive dharmas disclose this function's self-benefiting completeness (non-lapse, non-diminution, following wisdom, unobstructed, so that the beings transformed are not led astray); the four analytical knowledges disclose its other-benefiting unobstructedness (penetration without impediment, so that the expounding is unobstructed) — the four dharmas being the function of one and the same mastery; the prior paper took two (the ten powers and four fearlessnesses), this paper takes the remaining two (the eighteen distinctive dharmas and four analytical knowledges), and Part 4 is thereby complete in its joint listing.

III. The Core Argument

Section II has set out three things: the eighteen distinctive dharmas in full, their aspect throughout being "non- · following · unobstructed," and the discrimination of "distinctive" establishing the buddha-ground's fruition-virtues (2.1); the four analytical knowledges in full, penetration without impediment called "unobstructed knowing" (2.2); the import of their joint listing as "the Tathāgata's masterful function," to deliver beings (2.3). This section establishes the thesis: the eighteen distinctive dharmas and four analytical knowledges are not superpowers acquired beyond severing the defilements and turning into wisdom, but the already-established mastery turned toward beings as the completeness and opening-out of function. In three layers — the eighteen distinctive dharmas the aspect of self-benefiting completeness; the four analytical knowledges the aspect of other-benefiting unobstructedness; the two, with the ten powers and four fearlessnesses, filling the "function" heading.

3.1 The eighteen distinctive dharmas are the aspect of self-benefiting completeness ("non- · following · unobstructed"), not eighteen acquired capacities

Break first the "acquired superpower" reading. It pictures "becoming a Buddha and attaining the eighteen distinctive dharmas" thus: beyond the four wisdoms, ten powers, and four fearlessnesses, a Buddha trains up eighteen further lofty capacities possessed by a Buddha alone — as if the prior virtues were one batch and the eighteen distinctive dharmas another batch moved in. But the treatise does not say so. Looking at the full list (2.1), not one of the eighteen is "a capacity positively acquired"; all are aspects of "non- · following · unobstructed": the three non-lapses, the six non-diminutions, the three actions following wisdom, the three-times knowledge unobstructed.

First, "non-lapse" and "non-diminution" are privative terms, not the establishing of a new capacity. "Bodily action without lapse · speech without lapse · mindfulness without lapse" does not mean a Buddha acquires three "powers of not lapsing," but that in the Buddha's already-complete three actions (the doings of body, speech, and mind) no further fault is to be found — the aspect, upon what is already established, of "seeking a lapse and finding none," just as the prior paper's four fearlessnesses are the aspect of "seeing not the slightest mark of fear" (seeking a mark to be feared and finding none). So too "the six non-diminutions": in the six dharmas of zeal, vigor, mindfulness, wisdom, liberation, and the knowing-and-seeing of liberation, a Buddha ever has no regress or decline — not the acquiring of "six powers of not diminishing," but the aspect, of the already-possessed six dharmas, of "admitting no decrease." What the privative term negates is precisely "lapse" and "diminution"; what it discloses is the unbroken completeness of the already-established virtues, not a thing added beyond completeness.

Second, "following wisdom" is a term of conformity, not a separately running capacity. "All bodily · verbal · mental action following wisdom" does not mean a Buddha acquires "a power of making the three actions follow wisdom," but that the Buddha's three actions all turn following the already-established wisdom (the four wisdoms, P04), no action escaping wisdom, no doing not comprised by wisdom. This is the prior paper's extension: the four wisdoms being the Tathāgata's cognitive structure, the Buddha's three actions are without exception pervaded by this cognition — "following wisdom" being the aspect of the three actions wholly comprised by wisdom, not a capacity established apart from wisdom.

Third, "the three-times knowledge unobstructed" is a term of non-hindrance, precisely the ten powers' extension. "The wisdom knowing the past · future · present unobstructed" is the prior paper's ten powers (the all-kinds wisdom's knowing-as-it-is across ten domains) said, with respect to the three times, as "unhindered" — the past-lives power knowing the past, the divine-eye power knowing the future stations of birth, the exhaustion-of-taints and other knowings knowing the present, all "unobstructed." "Unobstructed" enters the names of the distinctive dharmas, the same brushstroke as the "unobstructed knowing of the divine eye · of past lives" within the ten powers (P05, §2.1): the buddha's wisdom is distinctive precisely in being "unhindered." This "unobstructed" is this division's keynote (apratihata) self-disclosing in the three-times knowledge.

So the eighteen distinctive dharmas are the same buddha-ground's virtue of wisdom and virtue of severance, disclosed under the four aspects of "non-lapse · non-diminution · following wisdom · unobstructed" as self-benefiting completeness, not eighteen capacities added beyond self-benefit. This carries forward the Attainment axis's constant frame: the freedom of exhaustion is the aspect of exhaustion, the ten epithets a signature, the three bodies a manifestation, the four wisdoms turned, the ten powers wisdom's knowing-as-it-is, the eighteen distinctive dharmas the virtues' non-lapse-non-diminution-unobstructed — one and the same frame, not one of them "acquired."

3.2 The four analytical knowledges are the aspect of other-benefiting unobstructedness (exposition penetrating without impediment): "unobstructedness" turned toward beings

The second layer establishes the provenance of the four analytical knowledges. The four analytical knowledges, too, are not four kinds of eloquence-power a Buddha acquires beyond wisdom-and-severance, but the "other-benefiting unobstructedness" aspect of the same mastery — the aspect, when the "unobstructed" knowing teaches and delivers beings, of penetrating without impediment the four matters of meaning, dharma, expression, and eloquence. The proof is in the treatise's closing (2.2): "penetrating these four matters without impediment is called unobstructed knowing" — the unobstructed being "penetration without impediment." The substance of the four analytical knowledges is precisely "penetration without impediment," not four capacities separately possessed.

This "unobstructedness" is this division's keynote, "unobstructed mastery" (apratihata), turned toward beings in exposition. The prior paper's two other-benefiting fearlessnesses (declaring what obstructs the path · declaring the path to the end of suffering) already showed the Buddha's fearlessness in "speaking"; this paper's four analytical knowledges open out, within that "speaking," four unobstructed knowings: the meaning signified penetrated without impediment (meaning), the dharma signifying penetrated without impediment (dharma), the speech expressing penetrated without impediment (expression), the responsive masterful expounding penetrated without impediment (eloquence). It is the same function of "teaching and delivering beings": said with respect to its being "unchallengeable," it is the four fearlessnesses; said with respect to its "penetration without impediment," it is the four analytical knowledges. And this is the extension of the prior paper's observation wisdom, "well observing the particular and common marks of dharmas, turning unobstructed," "in the great assembly… teaching and resolving doubts" (P04): the observation wisdom's "turning unobstructed" opened out toward beings as speech is the four unobstructed knowings. So the four analytical knowledges are not four capacities acquired apart from speaking, but the aspect of the already-established mastery (wisdom) turned toward beings in "speaking" with penetration without impediment.

Especially to be marked: the name of the four analytical knowledges enters with "unobstructed" (無礙); and the fourth, "the unobstructed knowing of eloquence," further bears "mastery" (the treatise: "mastery in expounding among the three knowings is eloquence"). This division's keynote of "unobstructed mastery" (無礙自在) is, in the name of this fruition-virtue, nearly present on the face of the words — the four analytical knowledges being an "unobstructed" and "masterful" expounding. So the four analytical knowledges most directly show this paper's frame: function is the aspect of mastery turned toward beings; the four analytical knowledges are precisely this mastery expounding to beings in the manner of "unobstructedness."

3.3 The eighteen distinctive dharmas and four analytical knowledges, with the ten powers and four fearlessnesses, fill the "function" heading: completeness and opening-out, the import being to deliver beings

The third layer gathers up in import. The eighteen distinctive dharmas and four analytical knowledges, taken together with the prior paper's ten powers and four fearlessnesses, are the full breadth of the already-established mastery (name · body · wisdom) turned toward beings as "function." The Avataṃsaka's verse lists the ten powers · fearlessnesses · eighteen distinctive dharmas together and names them outright "the Tathāgata's masterful function" (2.3), their import "all manifested to deliver beings." The four dharmas of Part 4 (P05 · P06) — the ten powers · four fearlessnesses · eighteen distinctive dharmas · four analytical knowledges — thereby together fill the axis's frame in its "function" heading.

Among the four, two aspects of "function" appear: function's "completeness" and function's "opening-out." The ten powers (wisdom's knowing-as-it-is) and the eighteen distinctive dharmas (the virtues' non-lapse, non-diminution, following wisdom, unobstructed) disclose function's "completeness" — a Buddha's virtue of wisdom fully bright, the three actions of discipline-concentration-wisdom without lapse or diminution, the three actions following wisdom, the three-times knowledge unobstructed: the aspect of mastery's "self-benefit complete"; and only because self-benefit is complete does its deliverance of beings not err, not regress, not run dry. The four fearlessnesses (the lion's roar of seeing not the slightest mark of fear) and the four analytical knowledges (the exposition of penetration without impediment) disclose function's "opening-out" — a Buddha's teaching unchallengeable, the four of meaning-dharma-expression-eloquence penetrated without impediment: the aspect of mastery's "other-benefit unobstructed"; and only because other-benefit is unobstructed is its deliverance of beings all-pervading, unobstructed, responsive. Completeness is why the function can be relied upon; opening-out is why the function reaches things. Both are the function of one and the same mastery, not two affairs.

So the axis's frame has all four headings complete — name (the readable aspect, P01) · body (the visible aspect, P03) · wisdom (the cognitive aspect, P04) · function (the world-facing, being-delivering aspect, Part 4, P05 · P06). All four are disclosures of one buddha-fruit mastery, not four batches of things acquired apart from the mastery. And this division's keynote of "unobstructed mastery" is densest in the "function" heading: the ten powers' "unobstructed knowing of the divine eye · of past lives," the eighteen distinctive dharmas' "three-times knowledge unobstructed," the four analytical knowledges' "four unobstructed knowings" — "unobstructed" entering the names of the buddha-virtues three times over. A Buddha's mastery, in its function's completeness and opening-out, takes "unobstructedness" as its aspect throughout: knowing unobstructed (the ten powers · the three-times knowledge unobstructed), challenging unobstructed (the four fearlessnesses, unchallengeable), speaking unobstructed (the four analytical knowledges, penetration without impediment). This ultimate sense — that "unobstructed function necessarily turns toward beings" (not abiding in nirvāṇa while ever raising the function of benefiting others) — is gathered up by this division's closing paper, P10.

✅ Doctrinally sound: taken together, the three layers support "the eighteen distinctive dharmas and four analytical knowledges are not superpowers acquired beyond severing the defilements and turning into wisdom, but the already-established mastery turned toward beings as the completeness and opening-out of function" — the eighteen distinctive dharmas are the aspect of self-benefiting completeness (the three non-lapses · six non-diminutions · three actions following wisdom · three-times knowledge unobstructed, all aspects of "non- · following · unobstructed," not eighteen acquired capacities; the discrimination of "distinctive" establishing the buddha-ground's fruition-virtues); the four analytical knowledges are the aspect of other-benefiting unobstructedness (the four unobstructed knowings of meaning-dharma-expression-eloquence · "penetration without impediment is called unobstructed knowing" · "unobstructedness" turned toward beings in exposition); the two, with the ten powers and four fearlessnesses, fill the "function" heading (the Avataṃsaka names them outright "the Tathāgata's masterful function" · completeness and opening-out · the import to deliver beings · the division's keynote "unobstructed" entering the buddha-virtues' names three times). The discrimination of "distinctive" is recorded without adjudicating in the author's stead, its precise discrimination from the two vehicles and bodhisattvas, and its convergence with the bodhisattva division's "heteromorphic, not hierarchically superior" frame, reserved to the author (§V, Correction 2); the stage-and-knowing assignment of the four analytical knowledges is recorded without harmonizing (§V, Correction 3); the marks and signs are handed to P07, the great compassion and all-kinds wisdom to P08.

IV. Interdisciplinary Convergence

(This paper deliberately omits the interdisciplinary-convergence section; the rationale is given in §VI. The aspect of the "four analytical knowledges" might seem comparable to the modern notion of "communicative competence," to rhetoric's eloquence, or to translation studies' three layers of "meaning / name / expression" — the unobstructed knowing of meaning resembling semantic penetration, of dharma terminological precision, of expression fluent delivery, of eloquence on-the-spot oratory. Yet that is dominated by "expressive skill acquired within a particular context," only superficially like this paper's sense that "the four analytical knowledges take the all-kinds wisdom's 'penetration without impediment' as their substance (penetrating every meaning · dharma · expression, no one of them not penetrated; not a context-bounded technique)." Communicative skill can be limited by domain, language, or audience; a Buddha's four analytical knowledges take "penetration without impediment," the "unobstructedness" of no dharma not penetrated, as their aspect. The one is a relative expressive ability, the other the necessity of "no impediment." To force the convergence would falsely cast "the all-knowing's unobstructed exposition" as "pragmatic technique," and so it is better left out. The eighteen distinctive dharmas' "non-lapse · non-diminution," likewise, is not well compared to psychology's "stability of expert performance" or "skill automaticity" — that is the relative stability of proficiency, this the necessity of an already-complete virtue "seeking a lapse or diminution and finding none"; the reasoning is the same as the prior paper's refusal, and is not belabored.)

V. Middle-Way Corrections

This section clears away one common misreading bearing on the thesis, and plainly marks two adjudications reserved to the author.

❌ Misreading 1: "The eighteen distinctive dharmas / four analytical knowledges = eighteen capacities possessed by a Buddha alone plus four kinds of eloquence-power a Buddha trains up beyond the four wisdoms, ten powers, and four fearlessnesses (a sixth batch of treasures after name, body, wisdom, powers, and fearlessnesses)." This the paper breaks in full. Not one of the eighteen distinctive dharmas is "a capacity positively acquired"; all are aspects of "non- · following · unobstructed": the three non-lapses · six non-diminutions (privative terms, disclosing the already-established virtues' unbroken completeness, not the acquiring of "powers of not lapsing or diminishing"), the three actions following wisdom (a term of conformity, disclosing the three actions as wholly comprised by the already-established wisdom, not the acquiring of a "wisdom-following capacity"), the three-times knowledge unobstructed (a term of non-hindrance, the ten powers' extension to the three times) (3.1). The substance of the four analytical knowledges is the "unobstructedness" of "penetration without impediment," the aspect of the "unobstructed" knowing expounding before the assembly, not four kinds of eloquence acquired apart from speaking (3.2). To picture becoming a Buddha and attaining these two as "moving in eighteen capacities and four eloquences after the prior virtues" is to fall into just this error.

⚠️ Correction 2 (the buddha-ground's distinctiveness · not a cross-axis ranking; the discrimination recorded, the adjudication reserved): the Dazhidu lun discriminates "distinctive" by "in the latter eighteen the śrāvaka and pratyekabuddha have no share"; this paper records it to establish "the buddha-ground's distinctive fruition-virtues" (the fruit-level completely possesses these eighteen dharmas), and puts no verdict on cross-axis high and low. The treatise says "in the former eighteen the śrāvaka and pratyekabuddha have a share; in the latter eighteen they have no share" (2.1). What this discrimination establishes is this division's constant sense of "the fruit-level differs from the causal-level" — the fruition-statement that "only the buddha-fruit completely possesses these eighteen distinctive dharmas"; this is the buddha-fruit's aspect of completeness, not a cross-axis verdict of high and low. The further adjudications it involves — the precise extent of "distinctiveness" (how exactly the two vehicles' "share" in the former eighteen and "no share" in the latter eighteen are to be bounded), the difference between the bodhisattva's causal level and the buddha-fruit in these eighteen, the convergence of "distinctive" with this series' bodhisattva-division frame of "heteromorphic, not hierarchically superior" (異質而非高下), and the treatise-master's "thirty-six dharmas / former eighteen / latter eighteen" schema together with the variant splittings of the eighteen distinctive dharmas across the schools (the Sarvāstivāda and the Mahāyāna) — are all major cross-axis adjudications; this paper records the treatise without adjudicating in the author's stead, leaving all of it to the author and to cross-axis convergence. This paper takes only the one sense: the eighteen distinctive dharmas are the aspect of the buddha-ground's completeness (showing them fruit-level complete, not acquired capacities).

⚠️ Correction 3 (the four analytical knowledges' stage-and-knowing assignment · the causal-level / buddha-ground boundary recorded without adjudicating; variant renderings marked): First, the Dazhidu lun's marking of the four unobstructed knowings' resting-stage and comprised knowing ("the first and fourth within the nine stages, the second and third in the desire realm and the Brahmā heavens; the second and third worldly knowing, the first the ten knowings, the fourth the nine knowings," 2.2) is the treatise's stage-and-knowing statement about the four analytical knowledges in their general sense (inclusive of the causal level), while the buddha-ground's perfection of the four has its own establishment; the treatises variously hold the four's resting-stage, comprised knowing, and subject-object assignment, and this paper records the Dazhidu lun's own text without harmonizing among the positions in the author's stead, and puts no verdict on the causal-level / buddha-ground boundary. Second, the Chinese rendering "the unobstructed knowing of eloquence" (樂說無礙) is what the treatises commonly call "the unobstructedness of eloquence" (辯無礙) — a variant rendering, the referent one; and the small difference between rendering catur-pratisaṃvid's component as "knowing" (智) and as "analytical knowledge / unobstructed understanding" (無礙解) is likewise marked, not unfolded.

VI. Conclusion

Essential restatement. The Tathāgata's eighteen distinctive dharmas and four analytical knowledges are not superpowers a Buddha acquires beyond severing the defilements and turning into wisdom (the four wisdoms) and beyond the ten powers and four fearlessnesses, but the already-established mastery turned toward beings as the completeness and opening-out of "function." Three layers support this: the eighteen distinctive dharmas are the aspect of self-benefiting completeness — the three non-lapses · six non-diminutions · three actions following wisdom · three-times knowledge unobstructed, all aspects of "non-(lapse/diminution) · following (wisdom) · unobstructedness," the privatives disclosing the already-established virtues unbroken, the conformity disclosing the three actions wholly comprised by wisdom, the unobstructed being the ten powers' extension to the three times, not eighteen acquired capacities (3.1); the four analytical knowledges are the aspect of other-benefiting unobstructedness — the four unobstructed knowings of meaning · dharma · expression · eloquence, their substance the "unobstructedness" of "penetration without impediment," the aspect of the "unobstructed" knowing (the observation wisdom · the speaking of the four fearlessnesses) expounding before the assembly, not four eloquences acquired apart from speaking (3.2); the two, with the ten powers and four fearlessnesses, fill the "function" heading — the Avataṃsaka naming them outright "the Tathāgata's masterful function," the ten powers and eighteen distinctive dharmas disclosing function's "completeness" (self-benefit complete, so the deliverance of beings does not err), the four fearlessnesses and four analytical knowledges disclosing its "opening-out" (other-benefit unobstructed, so the deliverance of beings is without impediment): name · body · wisdom · function all one mastery's "turning / severing / manifesting / functioning," not acquired from outside; and this division's keynote of "unobstructed mastery" is most plainly marked in the names "the three-times knowledge unobstructed · the four unobstructed knowings" (3.3).

Guidance for practice. This paper corrects, for the practitioner, the thought of "seeking, beyond the four wisdoms, ten powers, and four fearlessnesses, the magical powers and eloquence of the eighteen distinctive dharmas and four analytical knowledges." One bound for the buddha-fruit pictures the fruition-virtues as things to be "got" batch by batch — having got the four wisdoms, then the ten powers and four fearlessnesses, then the eighteen distinctive dharmas and four analytical knowledges — and so, beyond the transformation of the basis, seeks a separate "virtue-getting" work for each batch. This paper is the remedy: the eighteen distinctive dharmas are not eighteen outwardly-gettable capacities, but the aspect of the already-complete three actions and six dharmas as "without lapse, without diminution," of the three actions as "following wisdom," of the three-times knowledge as "unobstructed" — that is, "the virtues being complete, lapse and diminution are of themselves absent; wisdom being bright, the three actions of themselves follow; wisdom being all-pervading, the three times are of themselves unobstructed," not eighteen things moved in beyond the virtues; and the four analytical knowledges still less an outwardly-forgeable eloquence, but the aspect of "penetration without impediment" — wisdom being penetrating, the speaking is of itself unimpeded. What the practitioner is to do, then, is not "to seek the distinctive dharmas and unobstructed knowings apart from the transformation of the basis," but still "to turn the defiled into the pure" (carrying on from P04 · P05: severing the two hindrances, turning the eight consciousnesses, perfecting the four wisdoms) — wisdom-and-severance once full, non-lapse and non-diminution are of themselves the aspect of the already-complete, following-wisdom and unobstructed of themselves the aspect of the three actions, penetration without impediment of itself the aspect of the exposition, as a mirror once bright reflects all without exception and clearly without exception, no flawless reflecting and no unimpeded imaging sought apart from the mirror. Especially to be kept in mind: to chase batch by batch after "gettable distinctive dharmas" and "forgeable eloquence" is to seek with the mind of "acquiring," and turns into a new bond; only complete the work of turning the defiled into the pure, and the completeness and opening-out are of themselves its function.

Open questions. First, this paper cuts the Section IV interdisciplinary convergence (the four analytical knowledges and "communicative competence," the eighteen distinctive dharmas' non-lapse-non-diminution and "stability of expert performance," are only superficially alike). Second, the Dazhidu lun's discrimination of "distinctive" (in the latter eighteen the śrāvaka and pratyekabuddha have no share) and the adjudications it involves — the precise extent of "distinctiveness," whether the two vehicles and the bodhisattva's causal level have a share in these eighteen, the convergence with the bodhisattva division's "heteromorphic, not hierarchically superior" frame, the schools' variant splittings of the eighteen distinctive dharmas — are reserved to the author and to cross-axis convergence; this paper records without adjudicating in the author's stead. Third, the four analytical knowledges' stage-and-knowing assignment, and the boundary between the causal-level and buddha-ground four analytical knowledges, this paper records from the Dazhidu lun's own text without harmonizing. Fourth, Part 4 (P05 · P06) having filled the "function" heading with its four dharmas (the ten powers · four fearlessnesses · eighteen distinctive dharmas · four analytical knowledges), the remaining buddha-virtues are handed on in order: the thirty-two marks and eighty signs (the form-body's mastery-signature) to TATHAGATA-P07; the great loving-kindness and compassion and the all-kinds wisdom (function in its full breadth toward beings · the great compassion on which the eloquence of the four analytical knowledges rests) to P08; the Tathāgata's ten masteries and permanence-bliss-self-purity (the fruit-level's ten masteries · the four nirvāṇic virtues) to P09; and the ultimate sense that "mastery's function necessarily turns toward beings, not abiding in nirvāṇa while ever raising the benefiting of others" (the non-abiding nirvāṇa) is gathered up by this division's closing paper, P10. Further, the great compassion on which the four analytical knowledges' "eloquence" rests (expounding without impediment for the sake of beings), together with the "for the sake of beings" function pointed to by the prior paper's two other-benefiting fearlessnesses, is concluded at P08 and P10.

★ TATHAGATA-P05, "The Ten Powers and the Four Fearlessnesses" (same Part · the baton passed): P05 took the first two of the Avataṃsaka's "Tathāgata's masterful function" cluster (the ten powers · four fearlessnesses), establishing them as "knowledge-powers" and "the fearlessness disclosed by the completeness of wisdom-and-severance"; this paper takes the remaining two (the eighteen distinctive dharmas · four analytical knowledges), establishing the eighteen distinctive dharmas as the aspect of self-benefiting completeness and the four analytical knowledges as the aspect of other-benefiting unobstructedness. The four dharmas of Part 4 (P05 · P06) together fill the axis's "function" heading — the ten powers and eighteen distinctive dharmas disclosing function's "completeness," the four fearlessnesses and four analytical knowledges its "opening-out."
★ TATHAGATA-P04, "Turning Consciousness into Wisdom" (the source of function): P04 set the four wisdoms as the Tathāgata's cognitive structure. This paper's "three actions following wisdom" is the three actions wholly comprised by the four wisdoms; the "four analytical knowledges" is the observation wisdom's "turning unobstructed · teaching and resolving doubts" opened out toward beings; the "three-times knowledge unobstructed" is the all-kinds wisdom (accomplished by the four wisdoms) said as unhindered across the three times — the eighteen distinctive dharmas and four analytical knowledges all the function of the four wisdoms, not acquired apart from them.
★ TATHAGATA-P01, "The Ground Where Naming Is Full" · P02, "Two Sets of Ten Masteries" · P03, "Mastery Appearing as Three Bodies" (the frame): this paper carries forward the Attainment axis's constant frame — name (the ten epithets, P01) · body (the three bodies, P03) · wisdom (the four wisdoms, P04) · function (the ten powers, four fearlessnesses, eighteen distinctive dharmas, four analytical knowledges, Part 4) are all one buddha-fruit mastery's "turning / severing / manifesting / functioning," not acquired from outside; P02's judgment that the fruit-level is not the causal-level brightened is confirmed in "the eighteen distinctive dharmas as the buddha-ground's distinctive fruition-virtues" (only the fruit-level completely possesses these eighteen).
TATHAGATA-P08, "Great Loving-Kindness and Compassion, and the All-Kinds Wisdom" (forthcoming · function in full breadth): the great compassion on which this paper's four analytical knowledges' "eloquence" rests (expounding without impediment for the sake of beings), and the import of function as "all manifested to deliver beings," are gathered up in their full breadth at P08, in the great compassion and all-kinds wisdom.
TATHAGATA-P10, "The Ultimate Non-Abiding Nirvāṇa: The Terminus of Both Axes" (closing the division): this paper's ultimate sense — that "unobstructed function necessarily turns toward beings, not abiding in nirvāṇa while ever raising the benefiting of others" — is gathered up at P10; the non-abiding nirvāṇa's "not abiding in nirvāṇa" is precisely the ground on which the function of the eighteen distinctive dharmas and four analytical knowledges is ever raised, concluded there.

Kumārajīva. Listing the eighteen distinctive dharmas one by one: the three non-lapses (body · speech · mindfulness); no errant ideation · no unconcentrated mind · no inattentive equanimity; the six non-diminutions (zeal · vigor · mindfulness · wisdom · liberation · the knowing-and-seeing of liberation); the three actions following wisdom (body · speech · mind); the three-times knowledge unobstructed (past · future · present). Their aspect throughout is "non- · following · unobstructed." CBETA-collated. ↩
Dazhidu lun, fascicle 26 ("Exposition of the Eighteen Distinctive Dharmas"), T25n1509_p0247b19. The treatise-master raises a self-set question to discriminate the sense of "distinctive": in the latter eighteen dharmas the śrāvaka and pratyekabuddha have no share, hence these alone are named "distinctive." This paper records the treatise's plain sense to establish the buddha-ground's distinctive fruition-virtues; the precise discrimination from the two vehicles and bodhisattvas is reserved to the author (see §V, Correction 2). ↩
Dazhidu lun, fascicle 25 (at the close of the chapter on the four fearlessnesses, continuing with the four unobstructed knowings), T25n1509_p0246a22. Listing the four unobstructed knowings of meaning · dharma · expression · eloquence, with "earth" as the example (its solid mark is the meaning · its name is the dharma · the speaking of it is the expression · mastery in expounding among the three knowings is eloquence), closing "penetrating these four matters without impediment is called unobstructed knowing." The Chinese "the unobstructed knowing of eloquence" (樂說無礙) is what is commonly called "the unobstructedness of eloquence" (辯無礙). ↩
Dazhidu lun, fascicle 25 (in the chapter on the first matters), T25n1509_p0246b13. Marking the four unobstructed knowings' resting-stage and comprised knowing: the first (meaning) and fourth (eloquence) within the nine stages, the second (dharma) and third (expression) in the desire realm and the Brahmā heavens; the second and third worldly knowing, the first comprising the ten knowings, the fourth the nine knowings. This paper records the treatise's own text; the variant positions of the treatises and the causal-level / buddha-ground boundary are not harmonized in the author's stead (see §V, Correction 3). ↩
Mahāvaipulya-buddhāvataṃsaka-sūtra (eighty-fascicle Avataṃsaka), fascicle 14 (verse), T10n0279_p0075a06. Trans. Śikṣānanda. The verse lists "the Tathāgata's ten powers · fearlessnesses · eighteen distinctive dharmas · measureless virtues" together, "all manifested to deliver beings," and marks "knowing-minds, instructing, the supernormal feet… all the Tathāgata's masterful function" — the words "the Tathāgata's mastery" (如來自在) present on the face of the scripture. The prior paper (P05, ⁵) cited this verse to establish the import of the ten powers and four fearlessnesses; this paper cites it again to establish the import of the eighteen distinctive dharmas (same fascicle, same locus, T10n0279_p0075a06). ↩ ↩²
