What this concept is saying

The Three Contemplations—三觀 (*sānguān*, “three contemplations”)—are the Tiantai teachings of:

- 空觀 (*kōngguān*), contemplation of emptiness; - 假觀 (*jiǎguān*), contemplation of provisional existence; - 中觀 (*zhōngguān*), contemplation of the middle.

In the Perfect Teaching of Tiantai, these are not three theories about reality, nor three lenses that take turns replacing one another. They are three inseparable dimensions of a single act of clear seeing: 一心三觀 (*yīxīn sānguān*), “the Three Contemplations in one mind.”

Their scriptural-philosophical basis is Nāgārjuna’s famous verse in the *Mūlamadhyamakakārikā*, preserved in Kumārajīva’s Chinese *Zhong lun* (《中論》):

「眾因緣生法,我說即是無;亦為是假名,亦是中道義。」

A commonly transmitted variant begins 「因緣所生法,我說即是空」. The essential sequence is the same: what arises through causes and conditions is empty; it is provisionally designated; and this is the meaning of the middle way. Tiantai condenses this into 即空、即假、即中—“immediately empty, immediately provisional, immediately middle.” The “threefold identity” is a distinctly Tiantai way of unfolding the verse; it should not be confused with merely quoting Nāgārjuna word for word. The received Chinese text can be checked in the [CBETA edition of the *Zhong lun*](https://cbetaonline.dila.edu.tw/zh/T1564).

To understand the Three Contemplations, begin with something ordinary: a harsh message from a colleague. The message appears on a screen; the body tightens; the thought arises, “They do not respect me”; anger begins preparing a reply. Tiantai does not ask us simply to declare all of this unreal. It asks us to see the event completely.

1. 空觀: contemplation of emptiness

Contemplation of emptiness sees that every phenomenon is 因緣所生 (*yīnyuán suǒshēng*), arisen through causes and conditions, and therefore has no fixed, independent 自性 (*zìxìng*, intrinsic nature).

The message is not an independently existing “insult” containing a permanent essence of hostility. Its meaning depends on language, tone, earlier exchanges, workplace hierarchy, the sender’s condition, one’s memories, present fatigue, expectations, and the interpretive act occurring now. Anger, too, is not an indivisible thing or a permanent self. It arises through contact, feeling, recognition, habit, bodily activation, and repeated mental narration.

To contemplate emptiness is therefore not to think, “Nothing happened,” or “My feelings are fake.” It is to see that neither the event, the emotion, nor the offended “me” exists by itself or possesses an unchanging core.

The classical name “from the provisional into emptiness” does not mean that an actually self-existing world is subsequently erased. One begins from things as conventionally experienced and penetrates their lack of independent nature. This loosens 見思惑—the delusions bound up with distorted views and grasping thought—and is associated with 一切智 (*yīqiè zhì*, wisdom concerning emptiness or universality).

But stopping here creates a danger. “Empty” can become a new object of attachment: nothing matters, distinctions are arbitrary, suffering is only an illusion, responsibility is unnecessary. Tiantai therefore insists that genuine emptiness cannot be severed from the next contemplation.

2. 假觀: contemplation of provisional existence

假 (*jiǎ*) here does not simply mean “fake.” It means that things exist through conditions, relations, functions, and designation rather than through an isolated essence. “Provisional” is closer than “false,” provided we do not hear “provisional” as “unimportant.”

Precisely because things lack a fixed nature, they can arise, change, affect one another, and be transformed. Medicine can relieve pain; an apology can repair trust; cruel speech can injure; institutions can distribute advantage and hardship; habits can be cultivated or interrupted. None has an independent essence, yet none is causally negligible.

Contemplation of the provisional thus restores all the distinctions that a shallow understanding of emptiness may flatten. It notices which words were used, what power relations are present, what response would be helpful, what another person may be able to hear, and what consequences different actions are likely to produce.

This is called “from emptiness into the provisional.” Having seen that no thing is fixed, the bodhisattva returns fully to the world of differences without being imprisoned by them. This contemplation is associated with 道種智 (*dàozhǒng zhì*), knowledge of the many kinds of paths, circumstances, capacities, and appropriate means. Liberation is not merely freedom from one’s own conceptual fixation; it becomes the ability to meet particular beings in particular conditions.

This is why 假觀 cannot be reduced to “positive thinking,” social convention, or the assertion that ordinary appearances are simply real after all. It is an empty provisionality: functional and distinguishable, but never self-grounded.

3. 中觀: contemplation of the middle

The middle is not a compromise between “things exist” and “things do not exist,” as though Buddhism were choosing a moderate quantity of existence. Nor is it a hidden absolute standing behind the empty and provisional worlds.

中觀 sees that the very same dependently arisen phenomenon is empty of intrinsic nature and provisionally operative. Its emptiness does not cancel its functioning; its functioning does not establish an intrinsic essence. To see this without falling into either reification or nihilism is the middle.

Thus, the message is empty: no fixed insult, fixed anger, or fixed self can be found. It is provisional: words were sent, habits were triggered, relationships are affected, and a response will have consequences. It is middle: these are not two layers pasted together but two inseparable truths of the one event.

The middle therefore does not mean hovering above life in detached neutrality. It is unobstructed involvement—responding carefully without turning oneself, the other person, or the conflict into a permanent entity.

This contemplation is associated with 一切種智 (*yīqièzhǒng zhì*), the comprehensive wisdom traditionally attributed to buddhahood. In the Tiantai account, it breaks the most fundamental 無明 (*wúmíng*, ignorance): not merely ignorance of a fact, but the deep tendency to divide reality into rigidly self-existing opposites.

Three, yet one

Some teachings present a pedagogical sequence: from provisional existence into emptiness, from emptiness back into provisional existence, and through both into the middle. The *Pusa yingluo benye jing* (《菩薩瓔珞本業經》), as quoted in both the *Fahua xuanyi* and the *Mohe zhiguan*, names these the “Contemplation of the Two Truths,” the “Contemplation of Equality,” and the “Contemplation of the Middle Way’s Supreme Meaning.” The first two serve as approaches to the third.

Tiantai’s Perfect Teaching does not deny the usefulness of that exposition. It denies that perfected contemplation consists of three mutually separate attainments. Zhiyi’s *Mohe zhiguan* (《摩訶止觀》) states:

「一空一切空,無假中而不空,總空觀;一假一切假,無空中而不假,總假觀;一中一切中,無空假而不中,總中觀。」

When emptiness is correctly contemplated, the provisional and middle are already present within it. When provisional existence is correctly contemplated, emptiness and the middle are present. When the middle is contemplated, it does not leave emptiness and provisional existence behind.

The text compares this to three eyes on the single face of Maheśvara: genuinely three, yet not three separate faces. It also employs a temporal analogy: arising suggests provisional presence, cessation suggests emptiness, and abiding suggests neither simple existence nor simple nonexistence—yet these distinctions concern one moment, not three unrelated realities. Every analogy has limits, but each is meant to protect the same point: “three” must not destroy unity, and “one” must not erase discernible dimensions.

This is also why the Perfect Teaching is described as accessible from the beginning. One does not first spend years manufacturing emptiness, later restore the world, and finally add a middle that reconciles them. Even a beginner’s contemplation is oriented toward all three, though the beginner’s realization is not thereby equal to a buddha’s. Tiantai’s doctrine of 六即 (*liùjí*, “six identities”) guards this distinction: buddhahood is present as principle and direction without allowing an inexperienced practitioner to claim completed realization.

The Three Contemplations are therefore situated at the heart of the liberation path. They move practice through three inseparable freedoms:

- freedom from taking persons and things as fixed; - freedom to engage their concrete differences compassionately; - freedom from dividing emptiness and compassionate activity into rival truths.

The *Fahua xuanyi* (《妙法蓮華經玄義》) summarizes their mutual inclusion:

「一法即三法,三法即一法;一智即三智,三智即一智。智即是境,境即是智,融通無礙。」

The contemplated reality and the wisdom contemplating it are not ultimately two sealed-off substances. As fixation relaxes, the world disclosed by contemplation and the wisdom that knows it become mutually unobstructed.

A walkthrough in everyday life

Imagine that your partner has seen your message but has not replied for several hours. You are tired after work, and the phone is already in your hand.

First comes the unexamined story: “They are ignoring me. I am no longer important to them.” The mind treats “being ignored” as a property residing inside the unread conversation and treats “the rejected me” as a stable person to whom this is happening. It then searches old conversations for evidence, checks online status, and drafts a cold reply.

Now walk through the event according to the classical meanings of the Three Contemplations.

Empty contemplation: Examine what is actually arising through conditions.

There is a screen image, a remembered expectation, bodily unease, an unpleasant feeling, recognition of a familiar pattern, and an interpretation. The interpretation depends on past experiences, fatigue, attachment, notification design, uncertainty, and lack of information. Your partner’s silence may depend on work, illness, distraction, avoidance, loss of battery, emotional hesitation, or many conditions you do not know.

The point is not to replace the painful story with a cheerful guess. Both “They hate me” and “Everything is certainly fine” exceed the available conditions. Empty contemplation sees that “rejection” has not appeared as an independent essence. Anxiety is also conditioned: real as an experience, but neither permanent nor identical with “who I am.”

The common mapping error is to say, “The relationship is empty, so it does not matter.” That is not 空觀; it is nihilistic dismissal. Emptiness removes imagined self-existence, not causal consequence or lived pain.

Provisional contemplation: Attend carefully to functioning distinctions.

Although no fixed rejection can be found, there is still a particular relationship with a particular history. Perhaps delayed replies have previously signaled withdrawal. Perhaps your partner has explicitly asked for uninterrupted work time. Perhaps you tend to seek reassurance when exhausted. These distinctions matter.

You can now choose a skillful response: wait, regulate the body, send a simple check-in, state a need without accusation, or arrange a later conversation. Different people and circumstances require different means. A caring response is not generated by the abstract formula “everything is empty”; it requires knowledge of conditions.

The common mapping error is to equate 假 with deception: “The relationship is only fake.” In fact, its provisionality is what allows it to be nurtured, damaged, repaired, or transformed. If it possessed an unchangeable essence, no practice could alter it.

Middle contemplation: Do not split insight from relationship.

See the event as simultaneously ungraspable and consequential. There is no independently existing rejection to seize, yet the anxiety and relationship call for care. You need not absolutize the story in order to take the pain seriously. You need not deny the pain in order to avoid absolutizing it.

A middle-way response might be: “I notice I’m becoming anxious because I haven’t heard from you. When you have space, could you let me know whether everything is all right?” The exact wording is not itself 中觀. It is only an example of conduct that may flow from seeing both emptiness and provisional conditions. The contemplation lies in the quality of seeing, not in adopting a special communication script.

The common mapping error is to think the middle means “both sides are equally right” or “never take a position.” If abuse, danger, or exploitation is present, provisional discernment may require a firm boundary or immediate protection. Emptiness does not erase ethical differences, and the middle does not turn moral clarity into passivity.

The same walkthrough applies while commuting or scrolling a feed. An inflammatory post is empty of a self-existing meaning because it depends on editing, algorithms, prior beliefs, attention, and context. It is provisionally potent because it can direct anger, advertising revenue, votes, and treatment of other people. The middle sees both at once, allowing one neither to be captured by the post nor to dismiss its effects.

Algorithmic language can illuminate part of this process: what appears on a screen is shaped by many hidden conditions, and repeated engagement alters what appears next. But this is an analogy, not an equivalence. Dependent arising is not merely computational causation, mind is not established to be nothing more than an algorithm, and contemporary neuroscience has not “proved” Tiantai doctrine. Scientific models investigate measurable mechanisms; the Three Contemplations address the structure of grasping, knowledge, ethical response, and liberation. Their questions overlap at points but are not interchangeable.

Why contemporary people need it

Contemporary life repeatedly pushes the mind toward two extremes.

One extreme is reification. A diagnosis becomes “what I am.” A political label becomes the whole person. A failed project becomes proof of permanent inadequacy. A recommendation system repeatedly presents one preference until it feels like an essential identity. Empty contemplation interrupts this solidification: all these formations arose through conditions and can change when conditions change.

The other extreme is dismissal. “Everything is constructed” becomes an excuse not to care. Online speech is treated as unreal even when it reorganizes actual behavior. Structural injustice is reduced to individual perception. Spiritual language is used to bypass grief, fear, accountability, or conflict. Provisional contemplation interrupts this evasion: conditioned things have conditioned effects.

Middle contemplation prevents the remedy from becoming another disease. It does not let emptiness harden into nihilism, or practical concern harden into essentialism. One can act decisively while knowing that actor, opponent, action, and outcome are not fixed substances.

This is especially important for the bodhisattva path. Personal release from compulsive grasping corresponds to the liberating force of emptiness. Returning to the innumerable differences among beings corresponds to the provisional and to skillful means. Refusing to divide wisdom from compassion corresponds to the middle. In this sense, the Three Contemplations show how insight becomes service without losing its freedom.

They also belong with 止觀 (*zhǐguān*, calming and contemplation). The *Mohe zhiguan* correlates three modes of calming with the Three Contemplations:

- 體真止, resting through realization of the true, corresponds to emptiness; - 隨緣方便止, calming that follows conditions through skillful means, corresponds to the provisional; - 息二邊止, calming that brings the two extremes to rest, corresponds to the middle.

止 is not blank suppression, and 觀 is not endless analysis. Calming prevents the mind from being swept away; contemplation makes the character of the event clear. Tiantai describes these as causes, with the corresponding forms of wisdom as fruits. Yet in the Perfect Teaching, these causes and fruits are internally integrated rather than sealed into isolated compartments.

The tradition even applies the Three Contemplations to ethical discipline. Empty contemplation undermines the grasping and distorted views from which violations arise. Provisional contemplation discerns the countless conditions, needs, and consequences relevant to conduct. Middle contemplation addresses fundamental ignorance and prevents ethics from collapsing either into rigid rule-worship or into “nothing ultimately matters.”

Nor is the practice confined to formal seated meditation. The *Fahua xuanyi* applies “empty, provisional, and middle” even to sound. A car horn, a child crying, praise from a manager, or a notification tone can become the field of contemplation: conditioned and ungraspable, conventionally distinct and effective, and therefore middle. The object is not a special mystical substance. Every sensory encounter can disclose the three truths.

Common misunderstandings and clarifications

“Empty, provisional, and middle are three stages that must always be completed in order.”

They can be taught sequentially, and the sequential account has real pedagogical value. The classical formula speaks of entering emptiness from the provisional, returning from emptiness to the provisional, and entering the supreme meaning of the middle. But Tiantai distinguishes this from the fully “perfect” meaning. If the three remain merely successive and separate, one has, in the terminology of the *Mohe zhiguan*, “gained the separate but lost the perfect.” In 一心三觀, each contemplation includes the other two.

“Emptiness means that nothing exists.”

Emptiness means absence of independent intrinsic nature. It does not mean sheer nonexistence. A flame depends on fuel, oxygen, temperature, and countless other conditions; its lack of independence does not prevent it from burning a hand. Indeed, dependence explains both its appearance and its capacity to change.

“The provisional is an illusion that wise people should ignore.”

假 means conditioned and designated existence, not mere hallucination. Names, roles, promises, laws, bodies, and relationships lack self-nature, but they organize experience and produce effects. The bodhisattva’s compassionate work takes place precisely among these provisional differences.

“The middle is a third reality between emptiness and existence.”

That would turn the middle into another essence. The middle is the non-obstruction of emptiness and provisional existence: dependent arising is empty, and emptiness is manifest precisely as dependent arising. It is not a metaphysical substance hiding behind appearances.

“The middle means moderation in every practical decision.”

Not necessarily. The Buddhist middle way avoids false ontological extremes; it does not require choosing the midpoint between every pair of opinions. Compassion may sometimes be gentle and sometimes severe; ethical clarity may require refusing one side outright. What makes a response “middle” is freedom from reification and nihilism, not numerical compromise.

“If all three are present from the first moment, beginners are already fully awakened.”

The orientation of perfect contemplation is complete, but the practitioner’s realization may be shallow, unstable, or mainly conceptual. This is why the *Fahua xuanyi* pairs the Three Contemplations with the teaching of the Six Identities. Zhiyi warns:

「若欲免貧窮,當勤三觀;欲免上慢,當聞六即。」

Without contemplation, one remains spiritually “poor”: doctrine has not become lived insight. Without hearing the distinctions represented by the Six Identities, one may become arrogant and mistake an intellectual glimpse for buddhahood. Study and inward contemplation correct one another.

“Three Contemplations means thinking three sentences about every experience.”

Deliberately thinking “empty, provisional, middle” can be a useful beginning, but the mature practice is not mechanical labeling. It is a transformation in how phenomena are known. One no longer instinctively turns conditions into substances, emptiness into negation, or distinctions into permanent divisions.

“Tiantai is simply restating Madhyamaka.”

Tiantai receives the decisive inspiration from the *Zhong lun* verse, but its formulation of the Three Truths, their mutual identity, their coordination with contemplation, calming, the three wisdoms, the three eyes, and its classification of teachings belongs to Tiantai’s own systematic development. Intellectual honesty requires preserving both the Indian source and the distinctiveness of the Chinese Tiantai interpretation.

“Insight into emptiness makes learning doctrine unnecessary.”

Tiantai explicitly rejects the split between inward contemplation and responsible hearing. Experience without doctrinal discrimination easily becomes self-confirming; doctrine without practice becomes stored vocabulary. “Cultivating inward contemplation” produces the wealth of Dharma, while “rightly trusting what is heard” restrains spiritual conceit.

Ultimately, the Three Contemplations are not a way of making reality more complicated. They reveal why our ordinary alternatives are too simple. We assume that something must either be solidly real or completely nonexistent; that compassion must either cling or withdraw; that liberation must either escape the world or be swallowed by it.

Tiantai answers: because phenomena are dependently arisen, they are empty; because they are empty, they can appear and function provisionally; because emptiness and provisional functioning are inseparable, they are middle. To realize this is not to leave everyday life behind. It is to meet each message, body, sound, conflict, and relationship without imprisoning it in an essence—and without abandoning it to indifference.

定义与核心要义

三观者,空观、假观、中观也。天台圆教以《中论》「因缘所生法,即空、即假、即中」为宗本,立三观为一心圆具、不可思议之观法,非次第别立,而是一念中圆照三谛无碍。

主要阐述

一、三观之名义与因果配属。《妙法莲华经玄义》与《摩诃止观》同引《璎珞经》立三观名:从假入空名「二谛观」,从空入假名「平等观」,二观为方便道,得入中道第一义谛观。 《玄义》进一步以观为因、智为果:用从假入空观为因,得一切智果;用从空入假观为因,得道种智果;用中观为因,得一切种智果。并申明「别则观因智果」,观属因位,智属果位。 《摩诃止观》亦以三止三观为因,三眼三智为果:慧眼开见第一义、一切智成(真体);法眼开破障通无知、道种智成(俗体);佛眼开照无不遍、一切种智成(中道体)。

二、圆融互即之旨。《玄义》明言:「有漏即是因缘生法,即空、即假、即中;无漏亦即假、即中;非漏非无漏亦即空、即假。一法即三法,三法即一法;一智即三智,三智即一智。智即是境,境即是智,融通无碍。」引《释论》「三智一心中得」,谓「无前无后,为向人说,令易解故,作三智名说耳」。 《摩诃止观》以「摩醯首罗面上三目,虽三目而是一面」为喻,又云「一空一切空,无假中而不空,总空观;一假一切假,无空中而不假,总假观;一中一切中,无空假而不中,总中观」,是为「不可思议一心三观」。又以「生、住、灭、异」喻三谛:生喻假有,灭喻空无,住喻非空非有,三谛不同而秖一念。

三、三观之对治与遍历。《玄义》谓「若欲免贫穷,当勤三观;欲免上慢,当闻六即」,以三观对治偏闻之失,「修心内观,则有法财;正信外闻,无复上慢」,观与闻不可偏废。 又于声尘处明「即空即假即中」,谓耳根利者闻声即解因缘,「声即非声,非声亦声,非声非非声」,显示三观非仅坐禅所观之境,而是遍于六尘一切法之观法。 《摩诃止观》以观心为枢要:「观名佛知,止名佛见,于念念中止观现前,即众生开佛知见」;又以三观持戒:即空观灭见思之非,即假观灭尘沙之非,即中观灭无明之非。

四、别圆之判。《玄义》以麁妙判三观高下:藏通两佛虽有一切种智之名而「不破别惑,此智不成故不用」;别教「三智别异,果教未融」为麁;唯圆三智「因圆果圆,因妙果妙,谛妙智妙,正直舍方便,但说无上道」为妙。 《摩诃止观》辨云:若三种逦迤各各有异,「得别失圆」;若「虽三而一、虽一而三不相妨碍」,三种皆空以言思道断、皆假以但有名字、皆中以即是实相,「但以空为名即具假中,悟空即悟假中」,此为圆意。

五、圆顿初心。《摩诃止观》以「三铁」为喻:一铁种烧方利,一铁古珠即利,显圆教初心即修三观,不待二观成。 又明「圆顿止观相」:以止缘谛,则一谛而三谛;以谛系止,则一止而三止,一念具三相。

不同部类与译本的表述差异

一、三观立名。两部同引《璎珞经》作「二谛观」「平等观」「中道第一义谛观」; 《摩诃止观》另立三止名「体真止」「随缘方便止」「息二边止」,自言「此三止名虽未见经论,映望三观,随义立名」。 《玄义》则直呼「空观」「假观」「中观」与《璎珞》名并用。

二、判教用语。《玄义》以「麁妙」判摄诸教三观之优劣; 《摩诃止观》以「得别失圆」与「圆意」对举,以「虽三而一、虽一而三不相妨碍」为圆教判准。

三、独特配对。《摩诃止观》以「观为佛知、止为佛见」之配对独见此经; 又以「慧眼、法眼、佛眼」配「真体、俗体、中道体」,与三止三观一一相应。 《玄义》以三观配三智为因果结构,并以「六即」与三观并举对治偏失,此为《玄义》独有。

四、圆顿譬喻。《摩诃止观》以三铁喻、生住灭异喻显圆顿初心即修三观; 此等譬喻不见于《玄义》。

与相关概念的关系

一、三观与三智。三观为因,三智为果。从假入空观成一切智,从空入假观成道种智,中观成一切种智。 圆教则三智一心中得,无前无后。

二、三观与三止。《摩诃止观》立三止映望三观:体真止映空观,随缘方便止映假观,息二边止映中观。每止各具三义——止息、停止、非止止;前三成次三,后一具前三。

三、三观与三谛。三观所观之境即三谛。《摩诃止观》云「以止缘谛,则一谛而三谛;以谛系止,则一止而三止」,境观不二。

四、三观与六即。《玄义》以三观与六即并举:三观对治偏闻之贫穷,六即对治偏观之上慢,「修心内观,则有法财;正信外闻,无复上慢」。

五、三观与持戒。《摩诃止观》以三观持理戒,空假中各分三品判阶差:即空下声闻上通教菩萨;即假下三藏菩萨上别教菩萨;即中下别教菩萨上佛。

瑜伽師地論T1579 · 瑜伽部

此部論中所提及之「三觀」,乃以「於內、於外、於內外」三種觀境之分判為其核心義涵,與天台宗所謂「空觀、假觀、中觀」之三觀體系有所不同。論中以「住循三觀」一語貫串全段,旨在說明觀行者觀察身、受、心、法之三種面向。

所謂三觀者,據論文明示,其結構為內、外、內外三重觀境。此三觀之觀察對象涵蓋身、受、心、法四者,而原文特就身觀之三種分判詳加敷演,再推及受、心、法三觀。

第一層區別以「自、他、有情數身色」為準:緣根所攝、有執有受之色為內身觀;緣非根所攝、無執無受之色為外身觀;緣非根所攝、有執有受之色為內外身觀。

第二層區別以「定地、不定地;輕安、麁重」為準:自內定地輕安俱行色為內身觀;自內不定地麁重俱行色為外身觀;他輕安俱行、麁重俱行色為內外身觀。

第三層區別以「能造大種、所造色」為準:內能造大種色為內身觀;外能造大種色為外身觀;依能造大種色所生根境所攝造色為內外身觀。

第四層區別以「有識身、無識身」為準:有識身內色為內身觀;無識身有情數青瘀等位色為外身觀;無識身色於過去時有識性、有識身色於未來時無識性之相似法性、平等法性為內外身觀。

第五層區別以「自、他身相」為準:自中身髮毛爪齒等相為內身觀;他中身髮毛爪齒等相為外身觀;內外表身變異、不變異青瘀等相及相似法性、平等法性為內外身觀。

每一層區別之後,論皆重申「如是若緣依前三色所生受、心、法為境,隨其所應,當知即是住循三觀」,明三觀之觀境於身、受、心、法四者皆得成立,而以身觀為其根本所依。

綜觀全段,此論所言之「三觀」,乃以內外之分判為其核心結構。其獨特處在於將三觀與四念處之觀察相結合,以身觀為根本,並就「自他」、「內外」、「定不定」、「輕安麁重」、「有識無識」等不同面向,層層辨析內外觀境之別,最終歸結於受、心、法之三觀亦隨其所應而立。論中以「住循」二字標明觀行安住之相,以「相似法性、平等法性」點出內外觀境相通之理。

妙法蓮華經玄義T1716 · 經疏部

《妙法蓮華經玄義》論「三觀」(空觀、假觀、中觀),主要見於兩處脈絡:一者以三觀對治偏聞偏觀之病,二者以三觀遍歷六塵六入而觀解一切法。

第一,三觀與聞慧之雙修。智顗強調「聞、慧兼修,義、觀雙舉」,明偏廢之失:若「視聽馳散,如風中燈,照物不了」,但貴耳入口出、都不治心,是「由其不習觀也」;若觀心之人「謂即心而是,已則均佛」,都不尋經論,則「由不習聞也」。故結云:「若欲免貧窮,當勤三觀;欲免上慢,當聞六即。」此處三觀與「六即」對舉——三觀為修心工夫,六即為信解位次,二者相須,缺一不可。其言「修心內觀,則有法財;正信外聞,無復上慢」,正是此義。

第二,三觀遍歷六塵之觀法。於釋「經」義時,智顗以六塵六入皆可為「經」,並一一以三觀觀之。其觀聲塵云:「知脣舌、牙齒皆不可得。聲即非聲,非聲亦聲,非聲非非聲,聲為教、行、義本。」此乃典型之三重格式:先以空義破執,次以假義施設,終以中義雙照非有非無。釋字亦云:「非字非非字,雙照字非字。不可說非不可說,不可見非不可見。」於一色一聲皆「以三義織之,後用三觀結之」,即先以聞教三義分別,再以三觀總結歸於實相。此即下文「一切世間治生產業,皆與實相不相違背」之觀行落實。

第三,獨特術語與格式。此中所用三觀之表述,並非將空觀、假觀、中觀各別施設,而是以「即空即假即中」之圓融語式呈現,並以「即X即非X、非X亦X、非X非非X」之三句為觀法之骨架。所觀之境遍至色、聲、香、味、觸及內外入等「一塵一切塵」,故名「以三觀結之」——以三觀作為一切觀解之總收結。此乃智顗於本疏獨特發揮之觀法形式。

《妙法蓮華經文句》論三觀,明確使用「空觀、假觀、中觀」及「一心三觀」等語。三觀既可分別施設,又相即相攝:「三觀即三不退」,而「一心三觀」即「一心三不退」;又說觀一心即三心、三心即一心,一界即一切界,顯示三觀於一心中旋轉無礙,並非彼此割裂的三種觀法。

就所觀境與所得智慧而言,空觀觀十法界但有名字語言,配「辭無礙辯」;假觀觀心具十法界法,配「法無礙辯」;中觀觀十法界皆入實相,配「義無礙辯」。三觀又分別對應真諦、俗諦與中道第一義諦;其中中觀亦稱普聞三諦。至於智慧彼岸,空觀到一切智彼岸,假觀到道種智彼岸,中觀到一切種智彼岸。

三觀亦被用來說明修行中的不退、惑障與度生:空觀轉位不退法輪,假觀轉行不退法輪,中觀轉念不退法輪;空觀度四住百千眾生,假觀度塵沙百千眾生,中觀度無明百千眾生。又以空觀、假觀、中觀分別受法緣慈、眾生緣慈、無緣慈所薰,並分別入通佛慧、別佛慧、圓佛慧。原文明言「一心三觀有無量德」,所列僅為略說。

在觀行次第的表述上,《妙法蓮華經文句》說「觀空不住空,出假不住假,而入中不住中」,並以「雙照二諦」說其不休息;又稱「入空是自在觀,入中是大自在觀」。中觀尤以中道正觀、實相與廣博之性為其表述,如「中觀觀心,心即實相」,以及「中道正觀其性廣博」。

三觀還被廣泛用作觀心釋義:三觀妙慧能淨五住煩惱、免二死熱沙;三觀是修因,因喻蓮華;觀音聲即空、即假、即中,隨順三諦即是讚佛。又說三觀即中道而生法喜,顯示其術語常與「三諦」「中道」「實相」「觀心」連用。

對三觀整體結構的另一核心說明,是以「不思議三諦境」與「不思議三觀」相應:中道觀智觀十法界境,既明中道,又雙照二邊;「常樂觀如是等法」被解作三諦等法,並總結為不思議三觀。譬喻說法時,又以空觀如擣、假觀如篩、中觀如合,並指出三觀各不離戒、定、慧。

用詞方面,本書所用標準術語即「空觀」「假觀」「中觀」,合稱「三觀」,統攝時稱「一心三觀」;相關觀行亦表作「入空」「出假」「入中」,而不是以部類、經號或其他名稱替代。《妙法蓮華經文句》並常以「三觀三智」「三諦」「中道觀智」等複合語說明其境智關係。
