What this concept is actually saying

In esoteric Buddhism (密教, *mìjiào* / Tantric Buddhism), the maṇḍala (曼荼羅) is not just an image you look at or a meditation diagram you visualize. It is a *total environment* — sound, color, body, space, deity, mantra, mudrā, function — organized into a single coherent system. The most fundamental cut through that system is "the Three Families" (三部, *sānbù*), also called the Buddha–Lotus–Vajra Three Families (佛蓮金剛三部, *fóliánjīngāng sānbù*).

The classical statement is short but carries everything. The *Mahāvairocana Sūtra Commentary* (《大日經遮那成佛經疏》, commonly 《大日經疏》) says:

"其三部者,謂阿、沙(娑)、嚩三字是也。" "The Three Families are the three syllables: A, Sa (Sha), and Va."

And immediately afterwards: "A is the Tathāgata Family (i.e., Buddha Family); Sa is the Lotus Family; Va is the Vajra Family."

This is not arbitrary. The maṇḍala's entire architecture — its deities, its spatial arrangement, its mantra sounds, its colors, its rituals — is structured *as if it were the unfolding of these three syllables*. The sound-shape of language and the visual-shape of sacred space are treated as the same organism.

The six-fold anatomy of each Family

What makes 三部 unusual is that it's not a single-axis classification. Each "Family" simultaneously answers six different questions, and the answers are correlated. So to understand 三部 properly, you cannot reduce it to "three categories of deities" — it is six categorizations that happen to coincide. Let's lay them out:

| Dimension | 佛部 Buddha Family | 蓮華部 Lotus Family | 金剛部 Vajra Family | |---|---|---|---| | Seed syllable (字種) | 阿 (*a*) | 娑 (*sa*) | 嚩 (*va*) | | Principal deity (本尊) | 毘盧遮那 Vairocana (如來法界之身, "the Dharmadhātu-body of the Tathāgata") | 觀世音 Avalokiteśvara (= 阿彌陀 Amitābha) | 金剛藏 Vajragarbha (= 釋迦 Śākyamuni) | | Color | White (白) | Yellow (黃) | Reddish-yellow (赤黃) | | Primary activity (事業) | 息災 *śāntika* — pacifying | 增益 *pauṣṭika* — enriching | 降伏 *abhicāruka* — subduing | | Body position for mudrā | Head (頭上) | Heart (心間) | Navel (臍間) | | Maṇḍala spatial locus | Center (center is Mahāvairocana = 阿字) | North | South |

The *Commentary on the Vajraśekhara* / 《密宗道次第廣論》(Tsongkhapa's great treatise on the graduated path of Mantra) confirms this across the board, then adds that this same structure shows up in daily practice: at the start of every sitting session, the practitioner forms the mudrā of whichever Family they are cultivating that day and recites its seed-syllable mantra; the Buddha-Family mudrā is held at the head, the Lotus-Family mudrā at the heart, the Vajra-Family mudrā at the navel. So the Six-fold anatomy isn't a scholarly abstraction — it's how your body, breath, attention, and sound are arranged on the cushion.

Three Names, One Body — and Why "Three" Here Is Not "Three" There

A first trap is the word "three" itself. Buddhism has many "threes," and 三部 is not one of the better-known ones.

The *Mahāvairocana Commentary* explicitly distinguishes 三部 from another "three" — the 三三昧耶 (Three Samayas), which are the Three Jewels (Buddha, Dharma, Sangha), the Three Bodies ( trikāya), and the Three Vehicles. These are conceptual triples; 三部 is a *ritual-iconographic* triple. Same number, totally different logic. They must not be confused.

A second trap is more textual. Tsongkhapa's treatise uses 蓮花部 (*liánhuā bù*, "flower" in the everyday Chinese sense) in its chapters on the *kriyā* (事部) and *caryā* (行部) levels of practice, but switches to 蓮華部 (*liánhuá bù*, "lotus" in the more literary/transliterating sense) in the chapters on *yoga* (瑜伽部). The *Mahāvairocana Commentary* uses both spellings within the same text. So if you read "蓮花部" in one commentary and "蓮華部" in another, you are not reading about two different things — you are reading the same Family under two scribal conventions of Tang/Chinese Buddhism.

A third, more substantive trap: in *yoga-level* practice, the system *expands*. The same treatise, when it reaches the higher *yoga* sections, speaks of 四品 (four grades) and 五部 (five families): Tathāgata/Tathāgata-Family = Vairocana lineage, Vajra Family = Acala lineage, Lotus Family = Amitābha lineage, Jewel Family (寶部, *Ratna-kula*) = Ratnasambhava lineage, and Action Family (羯磨部, *Karma-kula*). That five-Family structure is a different map of the same sacred cosmos, used for higher initiations. 三部 in the *kriyā*/*caryā* sense and 五部 in the *yoga* sense should not be mixed.

Why activities map onto syllables

Perhaps the deepest thing in the classical sources is the idea that the three activities (pacifying, enriching, subduing) and the three syllables (*a*, *sa*, *va*) are *the same thing seen from two angles*. The Commentary explains that each Family also "turns through a five-syllable wheel (五字輪)" appropriate to its meaning. The seed syllable is not a label for the activity; the seed syllable *is* the activity, in sound-form. This is why the maṇḍala's spatial layout — center, north, south — can be read off the syllable structure: A unfolds in the center, Sa unfolds in the north, Va unfolds in the south, and from these unfold the entire iconographic world of deities.

So 三部 is best understood as a resonance-grammar: sound resonates into color, color resonates into body-region, body-region resonates into function, function resonates into spatial direction, and all of them resonate into the specific deities who embody that function most purely. It's a way of saying "spiritual work is not a single undifferentiated 'meditation' — it has shapes, and the shapes are coordinated across every dimension of the practitioner."


Life walk-through: the Three Families in an ordinary week

Imagine three scenes from a contemporary life. None of them is exotic — that's the point. The system was built to organize *practice*, but the patterns it describes are already there in how a person actually moves through difficulty, growth, and decisive action. The mistake would be to import the *ritual forms* of 三部 (mudrās, mantras, altar arrangements) where they don't belong; the right move is to *recognize* the three modes of being that 三部 was designed to formalize.

Scene 1 — Wednesday evening, 10:47 p.m. (息災 / Pacifying — Buddha Family)

You've had three back-to-back difficult meetings. A colleague implied your work was derivative. A client threatened to cancel a contract. You got an email about a family member's illness. Your jaw has been clenched since lunch. You're lying in bed and your thoughts are *running*. Not creating — running. The question here is not "what should I do?" The question is "how do I *stop burning*?"

This is the *kriyā*-sense of 息災: not "make a problem go away" (that's a folk-magic reading), but *settle the disturbance*. The Buddha Family's color is white, its body-position is the head, its syllable is *a* — the most "open," most "released" of the consonants, the vowel that asks nothing. The maṇḍala center is Vairocana, the "Dharmadhātu-body," which classical sources describe as the body's *settled ground*. The mode this Family formalizes is: *clarity above the chest, breath softening the head and shoulders, attention held at the crown where everything quiets down*. In contemporary terms: it's the half-hour you spend doing nothing before you sleep, the long shower, the phone call where you don't try to fix the other person, the moment you look at the ceiling and let the day's weight diffuse. The classical instruction "佛部印置頭上" — "the Buddha-Family mudrā is placed at the head" — is not asking you to imagine a white Buddha hovering over your scalp. It's pointing at a fact of human experience: *settling* happens from the top down. The forehead softens, the eyes release, the jaw unclenches, and only then does the heart follow. That's the Buddha-Family direction in your own nervous system.

The popular mistake here is to read 息災 as "doing a calming ritual to make external things calm down." The classical sources are clearer: 息災 is something done *to one's own continuum*, with external calming understood as a consequence of internal settling, not a deal struck with a deity.

Scene 2 — Saturday morning (增益 / Enriching — Lotus Family)

You've started learning a new instrument. The first week is wonderful and also humbling. You can play one clean phrase and then everything falls apart. You have to deliberately *not* compare yourself to the YouTube tutorial. The instrument is in your lap, your hand is making small mistakes, and yet something is — slowly, slowly — growing. You can feel the difference between "I am forcing this" and "I am letting this open." This is *pauṣṭika*: enrichment.

The Lotus Family's color is yellow (the color of ripening grain, of late morning light), its body-position is the heart, its syllable is *sa* — the soft consonant, the one that opens and gives. The principal deity is Avalokiteśvara, who is identified with Amitābha, the Buddha of boundless light. In the maṇḍala, this Family sits to the north. *Enrichment* is not acquisition; it's opening. The heart-position matters: the Lotus Family is not a chest-out acquisition mode, it's a *heart-front* mode — you hold the new thing *in front of your chest*, you don't strain toward it, you don't grip it. The mantra-form matches the function: *sa* in Sanskrit is a sibilant that opens the mouth and gives air without effort.

The contemporary mistake here is to read 增益 as "manifest more stuff — more money, more followers, more luck." The classical sources tie 增益 to *genuine growth*, which in human terms means the kind of slow opening where you stop forcing. The lotus doesn't hustle — it opens because that's what a lotus does in clean water. The Family was named for a flower that emerges from mud without being stained by it. The activity is growth *without grasping*.

Scene 3 — Sunday afternoon, deciding to leave (降伏 / Subduing — Vajra Family)

A friend has been borrowing money from you for two years and never paying back. Every conversation ends with another excuse. You love this person and you also know, with a clarity that has no anger in it, that continuing to lend is harming you. You need to *cut*. Not angrily. Not punitively. *Decisively*.

This is the *abhicāruka* mode: 降伏. The Vajra Family's color is reddish-yellow (fire-color), its body-position is the navel (the hara, the body's center of gravity and action), its syllable is *va* — the labial consonant that closes the lips and stops the breath. The principal deity is Vajragarbha, identified with Śākyamuni — the Buddha who *acted*, who left the palace, who sat under the tree, who walked into the fire at the end. The maṇḍala places this Family in the south, the direction of fire and midday. In classical sources the Vajra Family's function is *cutting through what cannot be pacified and what cannot be grown through*. The body-position matters here too: the navel is where action lives. The decision to end a pattern is not a head-thought and not a heart-feeling; it's a *gut* event. The syllable *va* literally closes the mouth — a sound-form of refusing to keep speaking the old story.

The contemporary mistake here is severe and common: people read 降伏 as "destroy enemies" and hear a license for aggression. The classical sources are emphatic that 降伏 is *subduing*, not *attacking*. What gets subdued is usually one's *own* obstruction — addiction, cowardice, the inability to say no, the habit of staying in a damaging situation out of misplaced compassion. The Vajra Family's compassion is not the soft compassion of the Lotus Family; it is the compassion of a surgeon, which is the same compassion as a gardener pruning — it cuts because it loves the living thing more than it loves the branch.

The walk-through summarized

Three ordinary moments, three different shapes of engagement:

- The night you cannot sleep → settle from the head down (Buddha Family / 息災 / white / Vairocana / center) - The morning you are learning something → open from the heart forward (Lotus Family / 增益 / yellow / Avalokiteśvara-Amitābha / north) - The afternoon you must decide → act from the navel, decisively (Vajra Family / 降伏 / red-yellow / Vajragarbha-Śākyamuni / south)

The classical system is more elaborate than this — it adds mudrās, mantras, maṇḍala installations, and initiatory transmissions. But the shapes of response it formalizes are already there in a contemporary life. To walk through them is to recognize that "spirituality" is not one thing — it has at least these three modes, and pretending otherwise leaves a person exhausted, because they will try to *gain clarity* (a head-move) when what is needed is *growth* (a heart-move), or try to *grow* (a heart-move) when what is needed is *cutting* (a navel-move).


Why a contemporary person benefits from knowing this

A person living in a high-stimulation environment — constant pings, constant news, constant demands on attention — is implicitly being trained to treat every moment as if it requires the same response. The Vajra-Family logic ("decide now, cut now") gets applied to situations that actually need settling (息災). The Lotus-Family logic ("open, grow, let it ripen") gets applied to situations that actually need a clean boundary (降伏). The Buddha-Family logic ("cool it, quiet it, let it be") gets applied to situations that actually need active cultivation (增益). The result is exhaustion and a kind of low-grade spiritual confusion — *why isn't this working?* — when the answer is that you have been using the wrong Family.

This is not a phenomenon unique to our era. The *Mahāvairocana Commentary* already lists the three activities (息、增、伏) as the four "common actions" (with 敬愛 *anurakti*, attraction, sometimes added) and warns that the *color* of any single activity must be matched to its Family. The insight is older than the smartphone; the smartphone just makes the mismatch more frequent.

There is a deeper reason, though, that has nothing to do with efficiency. The Three Families teach that the sacred is multi-form. A meditative tradition that recognized only one mode of spiritual response — only 息災, only quiet — would be impoverished. A tradition that recognized only 降伏 — only fierce cutting — would be brutal. The Three Families are a refusal of monochromatic spirituality. They say: there are at least three valid shapes of encounter with reality, and a serious practitioner has access to all three, knows which one the situation calls for, and can shift between them without rupturing continuity.

This is also where the syllable-structure (*a-sa-va*) does work that no doctrine-quote can do. Sound precedes thought. The way *a* opens, *sa* exhales, and *va* closes is *in* the body before it is in the head. Even if a contemporary reader never takes mantra initiation, even if they never build a maṇḍala, the recognition that *settling*, *opening*, and *cutting* are three different *bodily-motional* modes — not three different *ideas* — is itself a useful piece of self-knowledge. Many contemporary therapies, bodywork traditions, and contemplative disciplines have rediscovered this under different names. 三部 is one of the older, more rigorously systematized versions of the recognition.


Common misreadings and clarifications

1. "Three Families = Three Buddhas standing in a row." This is the iconographic misreading, encouraged by pictures of maṇḍalas that look like three clusters of figures. The Three Families are not three people; they are six-fold resonances. A Family is a *configuration* of syllable, color, deity, function, body-position, and spatial-direction. Reduce it to "a Buddha" and you've collapsed five dimensions into one.

2. "息災 = 'Make my problem go away.'" Folk-magic reading. The classical sources describe 息災 as a *settling* performed on the practitioner's own continuum, which may have secondary effects on circumstances, but is not a transactional request. The same goes for 增益 (enrichment is not a wish for more stuff) and 降伏 (subduing is not cursing enemies).

3. "降伏 means violence / destruction / cursing." This is the most damaging misreading, and it is widespread in popular Tantric culture online. The classical *Commentary on the Vajraśekhara* is careful: 降伏 is "subduing," and within each of the three Families, all three activities (息, 增, 伏) can be performed — but only with the Family's own color and form. A Buddha-Family 降伏 still looks white; a Lotus-Family 降伏 still looks yellow. The fierceness is *formally contained*. In life-walk terms: a clean "no" spoken from the navel is a Vajra-Family act; a cruel "no" spoken from contempt is not 降伏, it is unintegrated aggression, and the system does not bless it.

4. "Three Families = the Three Jewels (Buddha, Dharma, Sangha)." Same number, different concept. The Three Jewels are objects of refuge; the Three Families are configurations of practice. The *Mahāvairocana Commentary* explicitly distinguishes the two and warns that the names overlap but the contents do not.

5. "Three Families = the Three Bodies (trikāya)." Same caution. Dharma-body, Reward-body, Manifestation-body are ontological categories about the Buddha's mode of being; the Three Families are ritual-functional categories about how the practitioner arranges body-sound-color-space.

6. "Buddha Family = 'good and gentle,' Vajra Family = 'bad and fierce.'" This is a moral misreading. Each Family is a *complete* spiritual grammar; each can perform all four actions (with appropriate color shifts); none is the "evil" Family. The Vajra Family is called *vajra* (diamond/thunderbolt) because of its unbreakable clarity, not because it is wrathful. Wrathful deities in the maṇḍala are a specialization within the system, not a feature of the Family itself.

7. "蓮花部 and 蓮華部 are different things." In the materials used here, they are the same Family under two different scribal conventions. *Liánhuā* (蓮花) is the everyday word for "flower"; *liánhuá* (蓮華) is the literary/transliterating form used for the Sanskrit *padma* (lotus). Tsongkhapa's treatise uses the first spelling in its lower-level sections and the second in its higher-level sections. The *Mahāvairocana Commentary* uses both. If you encounter the spellings in two different texts, do not assume you are reading about two different deities.

8. "Three Families and Five Families are interchangeable." No. The Five-Family system (五部: Tathāgata, Vajra, Lotus, Jewel, Action) appears in the *yoga*-level sections of the same treatise and is a *differentiation* of the same sacred cosmos for higher initiations. It includes additional deities (Ratnasambhava for the Jewel Family, Amoghasiddhi for the Action Family) and additional lineage mappings (Acala for Vajra, Amitābha for Lotus). Using "Five Families" terminology inside a Three-Family ritual, or vice versa, would be a category error — like using the names of rooms on the second floor while you are still on the first.

9. "The color rules are rigid." The *Commentary* explicitly says: "亦隨一部中自有三事分別,如佛部中自有息災、增益、降伏也." Within a single Family, all three activities occur, and the color shifts to match the activity, not the Family. The Family-color is the *default resting state*; the activity-color is the *working state*. The system is not a fixed paint-by-numbers.


A closing observation

What the Three Families ultimately teach is that a maṇḍala is not an image but a *grammar*, and a practitioner is not a single instrument but an orchestra. The head knows how to settle, the heart knows how to open, the navel knows how to act. A serious life is one in which all three are kept alive and the right one is allowed to lead at the right moment — not because a ritual manual says so, but because the syllables *a*, *sa*, and *va* — open, exhale, close — are already the music the body has always been quietly making. The classical Chinese and Tibetan commentators built an extraordinarily elaborate system on top of this recognition. But the recognition itself does not require their elaborations. It requires only that you notice, the next time you lie awake, or learn something new, or have to say no, *where* in your body the response is trying to live — and whether you are letting it.

定义与核心要义

「三部」为密教曼荼罗之根本分类,指佛部、莲华部、金刚部之三分,亦总称「佛莲金刚三部」,简称「三部」。三部各有本尊、印契、密咒、真言字种、颜色、事业(息灾、增益、降伏)及曼荼罗方位之配属,为密教修行建置之核心架构。

主要阐述

《密宗道次第广论》将「三部」主要置于事部、行部之修法建置中加以阐述。本论以事部四种总续——《妙臂问经》、《秘密总续》、《苏悉地经》、《后静虑经》——统摄三部共同教法。《妙臂问经》分别论述佛、莲花、金刚三部之天神、财神、世间六道种姓、密咒、事业差别及承事方便;《秘密总续》说三部三千五百大曼陀罗及绘画、灌顶等通用仪轨;《苏悉地经》显说三部共同之修咒仪轨、事业仪轨、护摩法及所护三昧耶;《后静虑经》则明六种静虑及护持命力等支分。三部非仅名目之分类,乃借以统摄灌顶、三昧耶、承事、念诵、事业与成就等修道内容。

在日常行持中,修行者每日初座、早晨起床及其余座首,随所修之部结该部三昧耶印并诵密咒。三部各有相应印相与安置处:佛部印置头上,莲花部印置心间,金刚部印置脐间。尊胜等属佛部,观自在等属莲花部,金刚摧坏等属金刚部。供物加持时依次以三部咒加持;守护自身时,则以如来等三部一切业咒缚护上空诸天,此总咒称「三部总咒」。

《大毘卢遮那成佛经疏》(即《大日经疏》)则从字轮、本尊、颜色、事业及曼荼罗方位等多角度立论。本疏以三字表三部:阿字是如来部(即佛部),娑字是莲华部,嚩字是金刚部;又明每部随五字轮而转,随义相应之相。三部各配本尊与色:毘卢遮那是佛部,即如来法界之身,白色;观世音(阿弥陀佛)是莲华部,黄色;金刚藏(释迦牟尼)是金刚部,赤黄色。三部各摄一事:佛部为息灾用白,莲华部为增益用黄,金刚部为降伏用杂色;然一部之中亦可自有息、增、伏之别,唯随本法转色。

三部各有自部曼荼罗。本疏云「今此中随三部各各别有也」,如莲华部坛以观音为主;又从莲花部数起,莲花为初,金刚为第二部。曼荼罗方位之配对:坛中心是大日如来(同阿字),北边置莲华及诸眷属(同娑字),南边置执金刚及诸眷属(同嚩字)。阿字更生四字为大悲胎藏之叶,嚩字转生多字而称为「轮」,三部之曼荼罗组织寓于语言结构之中。

不同部类与译本的表述差异

一、「佛部」异称:《大日经疏》以「如来部」为佛部之异称,云「阿字是如来部」;《密宗道次第广论》亦称「如来部」,并言「如来等三部的一切业咒」。两部论疏互通此二名。

二、「莲花部」与「莲华部」之别:《密宗道次第广论》正文于事部、行部脉络用「莲花部」,而于瑜伽部论四品、五部之脉络改用「莲华部」(莲华部为弥陀种姓)。《大日经疏》则通作「莲华部」,又云「莲花部」「莲花为初即金刚为第二部也」,于同一疏中花、华二字并见。

三、三部与四品、五部之区分:《密宗道次第广论》于瑜伽部另立四品、五部之建置——如来及如来部为毘卢遮那种姓,金刚部为不动种姓,莲华部为弥陀种姓,宝部为宝生种姓,并论及羯磨部。此与事行部之佛、莲花、金刚三部分类不同,不应混称。

与相关概念之关系

《大日经疏》另说「三三昧耶」之佛法僧三宝、三身、三乘之三,虽同以「三」立名,却系另一组概念,与此处「三部」(佛莲金)所立之三应各别理解,不可混淆。

代表性原文引用

一、《大日经疏》:「其三部者,谓阿、沙(娑)、嚩三字是也。」「阿字是如来部,娑字是莲华部,嚩字是金刚部。」「大略有三部:毘卢遮那是佛部,即是如来法界之身,白色;次观世音是阿弥陀佛也,其身黄色;次金刚藏,即是释迦牟尼,其身赤黄色。」「佛部一向是息灾用白……莲华部一向是增益用,其色黄……金刚部一向是降伏用,其色杂也。」「今此中随三部各各别有也。」「前者坛法中心是大日如来,即同此中阿字。北边置莲华及诸眷属皆在一处,即是此中之娑字。南边置执金刚及诸眷属,即是此中之嚩字。」(以上见)

二、《密宗道次第广论》:事行部脉络用「莲花部」,瑜伽部脉络用「莲华部」;云「如其次第即三部咒」,并立如来等三部总咒以守护自身;又于瑜伽部云:如来及如来部为毘卢遮那种姓,金刚部为不动种姓,莲华部为弥陀种姓,宝部为宝生种姓。(以上见)

密宗道次第廣論B0068 · 藏傳論典部

《密宗道次第廣論》論「三部」,主要置於事部、行部的修法建置中,明稱為「佛、蓮花、金剛三部」,亦簡稱「佛蓮金剛三部」或「三部」。其中「佛部」又見作「如來部」;「蓮花部」的「花」字是本論正文所用字形,而非「蓮華部」。這些正是本論用以標示三部的術語形式。

本論以事部四種總續說明三部共同教法。《妙臂問經》分別論述佛、蓮花、金剛三部的天神、財神、世間六道種姓、密咒、事業差別及承事方便等;《秘密總續》則說佛、蓮、金剛三部三千五百大曼陀羅,以及繪畫、灌頂等通用儀軌,側重成熟法器之類;《蘇悉地經》顯說三部共同的修咒儀軌、事業儀軌、護摩法及所護三昧耶;《後靜慮經》所明六種靜慮及護持命力等支分,也被判為三部所共。因此,本論不是只作名目分類,而是藉三部統攝灌頂、三昧耶、承事、念誦、事業與成就等修道內容。

在具體行持中,修行者每日初座、早晨起床及其餘座首,隨所修之部結該部三昧耶印並誦密咒。三部各有相應印相與安置處:佛部印置頭上,蓮花部印置心間,金剛部印置臍間;尊勝等屬佛部,觀自在等屬蓮花部,金剛摧壞等屬金剛部。此處以本尊類別、印契、密咒及身體部位的配合,呈現三部在日常修持中的實際差別。

供物加持與守護儀軌亦依三部配列。加持供物時,本論依次列舉三種咒,明言「如其次第即三部咒」;守護自身時,又列如來等三部的一切業咒,並說縛護上空諸天所用者為「三部總咒」。由此可見,「三部」既各有部別咒法,也有共同適用的總咒與通軌;「如來部」在此即是佛部的另一名稱。

本論另於瑜伽部說四品與五部:如來及如來部為毘盧遮那種姓,金剛部為不動種姓,蓮華部為彌陀種姓,寶部為寶生種姓,並論及羯磨部。此處正文改用「蓮華部」,且所論是瑜伽部的四品、五部建置,不應與事行部的佛、蓮花、金剛三部混稱;兩種術語與分類在本論中各有其所屬脈絡。

大毘盧遮那成佛經疏(大日經疏)T1796 · 經疏部

本疏論「三部」,以佛部、蓮華部、金剛部三者為密教曼荼羅根本分類,茲述其要:

一、以三字表三部。本疏明言「其三部者,謂阿、沙(娑)、嚩三字是也」,又云「阿字是如來部,娑字是蓮華部,嚩字是金剛部」,使三部各有音聲表字。復說「每三部隨五字輪而轉,隨義相應之相」,以字輪展轉攝三部之義。

二、三部配三尊與三色。本疏云「大略有三部:毘盧遮那是佛部,即是如來法界之身,白色;次觀世音是阿彌陀佛也,其身黃色;次金剛藏,即是釋迦牟尼,其身赤黃色」。其中「如來部」亦稱「佛部」,二名互通,乃本部異稱之一例。

三、三部配三事。本疏云「佛部一向是息災用白……蓮華部一向是增益用,其色黃……金剛部一向是降伏用,其色雜也」,以部攝事而色隨之。復說「亦隨一部中自有三事分別,如佛部中自有息災、增益、降伏也」,明一部之中可有息、增、伏之別,唯依本法轉色而已。

四、三部各別有曼荼羅。本疏云「今此中隨三部各各別有也」,明三部各有自部壇法,如蓮華部壇以觀音為主,餘兩部可例知。又云「從蓮花部數之,蓮花為初即金剛為第二部也」。

五、三部與曼荼羅方位、字輪之配對。本疏云「前者壇法中心是大日如來,即同此中阿字。北邊置蓮華及諸眷屬皆在一處,即是此中之娑字。南邊置執金剛及諸眷屬,即是此中之嚩字」。從阿字更生四字為大悲胎藏之葉,從嚩字轉生多字而稱為「輪」,顯示三部之曼荼羅組織寓於語言結構之中。

末應區辨:本疏另說「三三昧耶」之佛法僧三寶、三身、三乘之三,雖同以「三」立名,卻係另一組概念,與此處「三部」(佛蓮金)所立之三,應各別理解。
