What This Concept Is About

You may have encountered expressions like 生生世世 (life after life) or 生生不已 (ceaseless arising) in Buddhist scriptures, and assumed that 生生 simply means the continuous flow of life, one rebirth after another. But the 生生 discussed here is another 生生 — one that is more fundamental, more abstract, and more vexing than 生生 in the sense of rebirth.

Here is how it arises.

Any 有為法 (saṃskṛta-dharma, conditioned phenomenon) — that is, anything that is produced and subject to arising and ceasing — is analyzed by Buddhism as having three basic characteristics at the moment it arises: 生 (utpāda, arising), 住 (sthiti, abiding), and 滅 (bhaṅga, ceasing). 生 means it has appeared; 住 means it persists; 滅 means it dissolves. These three are called the 有為三相 (the three characteristics of the conditioned).

Here is the problem. Are 生, 住, and 滅 themselves conditioned dharmas?

If they are, then 生 itself is also within arising and ceasing, and it too should have its own 生, 住, and 滅. But what about its 生? What is that "production of production" — namely, 生生 (jātijāti, "production of production")? Is it also a conditioned dharma? If so, it needs yet another "production of production of production" to produce it… and so on without end, never finding a first term.

This is a classic problem in Buddhist philosophy: the "infinite regress" problem. It is not merely a logical puzzle; it touches a fundamental question: when a thing is about to begin to exist, where does this "beginning" itself come from?

Within Buddhism, two major camps give diametrically opposed responses to this problem.

說一切有部 (Sarvāstivāda) — the school represented by the 《俱舍論》 (Abhidharmakośabhāṣya) — proposes this solution: to each of 生, 住, and 滅, assign a 隨相 (anulakṣaṇa, secondary characteristic). 生 is paired with 生生, 住 with 住住, 滅 with 滅滅 (in the Sarvāstivāda four-characteristic system, 異 (jarā, "decay") is paired with 異異, making four 本相 (mūla-lakṣaṇa, primary characteristics) and four secondary characteristics). 生生 means "the production of production" — it is the dharma that allows the primary characteristic 生 itself to arise.

The 《俱舍論》 states this very clearly: when one dharma arises, nine dharmas arise together with it — the dharma itself, the four primary characteristics (生, 住, 異, 滅), and the four secondary characteristics (生生, 住住, 異異, 滅滅). Among these, the primary 生 can produce the other eight dharmas, while the secondary 生生 can produce only the single dharma 生 among the primary characteristics. The treatise uses a simile to illustrate this difference in function: the primary 生 producing eight dharmas is like a hen that can hatch many chicks; 生生 producing only one dharma is like a hen that hatches but one chick. Both are real functions, differing only in breadth.

This leads to the core definitional statement of the 《俱舍論》: 「生能生所生,非離因緣合」— the function of the 生 characteristic lies in producing the dharmas that are produced, but this "ability to produce" is not self-subsistent; it is established only in dependence on the convergence of causes and conditions.

The 中觀 (Mādhyamaka) school — represented by the 《中論》 (Mūlamadhyamakakārikā) and the 《十二門論》 (Dvādaśamukhaśāstra) — fundamentally questions this solution. Nāgārjuna's refutation is extremely subtle, advancing on several levels.

On the first level, he attacks the direction of "mutual production." The Sarvāstivāda setup is: 生生 can produce the primary 生, and the primary 生 can also produce 生生 — the two produce each other. Nāgārjuna asks: if 生生 is produced from the primary 生, then as "that which is produced," how can it in turn produce the very 生 that produced it? That would be like a child who has not yet been born somehow being his own father. Conversely: since the primary 生 comes from 生生, on what grounds can it produce the 生生 that produced it? The verse says:

「若謂是生生,能生於本生;生生從本生,何能生本生?」 若谓是生生,能生于本生;生生从本生,何能生本生? *"If it is said that 生生 can produce the primary 生 — but 生生 arises from the primary 生; how can it produce the primary 生?"*

On the second level, he attacks via "not yet produced." Even setting aside the question of which produces which first, just ask: has 生生 itself arisen? If it has not yet arisen, it has no 自體 (svabhāva, self-nature); without self-nature, what does it use to produce the primary 生? The 《中論》 verse presses hard:

「若生生生時,能生於本生;生生尚未有,何能生本生?」 若生生生时,能生于本生;生生尚未有,何能生本生? *"If, while 生生 is being produced, it can produce the primary 生 — but 生生 does not yet exist; how can it produce the primary 生?"*

"While 生生 is being produced" — this seemingly subtle moment — is precisely the most incoherent: it is in the process of being produced, meaning it has not finished being produced; not finished, it has no complete self-nature; no self-nature, no capacity to produce. How can something not yet formed bring about something else?

The 《十二門論》 also records a rejoinder: the opponent offers the simile of a lamp. When a lamp is lit, it illuminates both itself and other things. Likewise, 生生, while being produced, can produce both itself and the primary 生. Nāgārjuna's reply is four characters: 是事不然 ("this is not so"). Why not? Because a lamp can illuminate itself and others precisely because the lamp and its light already exist simultaneously; but "生生 while being produced" means it has not yet completed itself — this is not the same as "the lamp has already been lit." The lamp illuminates because it has already ignited, not because it is "in the process of igniting"; if it has not yet ignited, it cannot even illuminate itself, let alone others.

On the third level, he summarizes into a dilemma: if every production requires yet another production to produce it, then we have infinite regress, never reaching a first term; if production does not require another production and can produce itself, then all dharmas should be able to produce themselves — but clearly this is not the case. A dilemma.

The Mādhyamaka conclusion is therefore: the mutual-production architecture of 生生 and the primary 生 does not hold. The characteristic 生 is not, as the Sarvāstivādins imagined, a real entity that can itself be produced by another 生.

The two schools differ in their commitments: the Sarvāstivādins want to uphold the reality of the three characteristics 生, 住, and 滅, and so posit 生生 to stop the regress; the Mādhyamikas want to refute the reality of the three characteristics, and so use the regress to break 生生. But on one point both sides agree: without 生生 to underwrite it, 生 itself cannot stand.

This seemingly hyper-technical debate actually concerns a very deep intuition: how does "beginning" itself begin?

A Walkthrough in Everyday Life

Let us pull the lens back from the treatises to everyday life.

Scene one: you set a goal for yourself.

"From tomorrow on, I will get up at six and go running every day." — This is a 生. A new habit, a new self-appointment, has arisen in you. This 生 itself also needs a 生生 to drive it — that is, the power that makes you "begin."

The question is: where does this 生生 come from?

You say: I have willpower. But doesn't willpower itself also need to be activated? You cannot first have willpower and then use it to activate willpower — in that case, the very act of activating your willpower would require yet another willpower to activate it… It is like trying to install a "start button" for yourself, but the button itself also needs to be pressed. You either have an infinite chain of buttons, or a button that does not need to be pressed — but then it would not be a button.

So in reality, when a goal collapses, it is not because you "lack willpower" — it is because the 生生 that would have activated willpower never arose. It is something more fundamental than willpower; it has no cause, no prior step; it is simply that one moment. If that moment does not come, everything after it is just spinning in neutral.

Scene two: scrolling on your phone.

You pick up your phone and open a short-video app. The first video appears. It hooks you; a second, a third… an hour passes. Which one is the 生 of "you started scrolling"?

Is it the moment of opening the app? Yes. But that moment of "opening the app" itself also needs a 生 — the impulse that made you "decide to open the app." That impulse also has its 生 — the one that made you "decide to decide"… At this point you realize that asking "what was the very first beginning" is much harder than asking "how long have you been scrolling."

Worse, you often feel "just one more and I'll stop" — this "stopping" is also a 生, and it too needs its 生生. And that 生生 never comes. It does not come because you do not want it to come; it does not come because "wanting it to come" is itself just another thought, and it too must be produced. The infinite-regress dilemma plays out for real in every "just one more."

Scene three: you tell someone a joke.

The punchline lands on the last line. But for the punchline to land, the setup must already be fully in place. You cannot deliver the punchline first and then set it up — that would not land. And you cannot wait until all the setup is complete and then "begin" to deliver the punchline — because the act of delivering requires a "now" in which to happen. Where does this "now" come from?

The question sounds absurd, but it is structurally identical to the 生生 dilemma: a process needs a starting point, and the starting point is not itself within the process. If you treat "delivering the punchline" as a process that needs preparation, then it too needs its own "delivering the punchline" — and you would be preparing forever, and it would never land. In fact, the moment the punchline lands is precisely the moment when you do not prepare the "delivering" but just deliver it — it does not need another "delivering" to push it.

This is where 生生 sits in life: it is not something that can be prepared, manufactured, or derived. It is that one moment of "coming directly." The more you try to find a cause for it, the less it comes; the less you look, the more it comes.

The most common place to misproject here is:

People often think 生生 is "the power that makes things begin" — such as resolve, motivation, willpower. But strictly by the definition in the treatises, 生生 is the production of 生 itself — it is second-order, not the first-order motive power itself. It is like resolving to go running — "making the resolution" is a thought, and it too must be produced. You cannot first "resolve to make a resolution" and then make the resolution. That moment of "directly having resolved" is 生生 — it has no cause; it is simply that one moment. You think it is your willpower at work, but willpower itself is only something that gets produced; the moment that actually produces it is precisely where willpower has no jurisdiction.

Why Contemporary People Need It

One: to recognize that "beginning" cannot be derived.

Contemporary people live in an era where everything must have a "cause," a "method," a "path." You ask "how do I start running," "how do I start writing," "how do I start changing," and the answers you get are always a pile of methods: start with five minutes, set a small goal first, first… Do these methods work? They work. But you will find that the more methods you use, the better you get at "preparing to begin" and the worse you get at "beginning." You hoard vast amounts of knowledge about "how to begin" and never begin.

The concept of 生生 tells you: beginning, structurally, cannot be driven by another "beginning." This is a logical impossibility, not a deficiency of method. What you need is not more "how to begin," but the recognition that "beginning" itself is uncaused, unconditional, unprepared — it can only come by itself. This recognition itself is a kind of liberation.

Two: to understand the predicament of self-reference.

The problem of 生生 is, in essence, the problem of self-reference: can a system explain its own origin? Can a thought think its own beginning?

Contemporary AI, algorithms, and systems theory keep hitting this wall. Can an AI model "improve itself"? Theoretically it can recurse, but each recursion requires an externally set objective function — that objective function is where 生生 sits: it is not generated by the system itself. Can an algorithm "self-initialize"? No — initialization must be performed externally. You cannot write code that says "I start myself," because the act of starting is not inside the code.

These contemporary technological predicaments are structurally identical to the logic of Nāgārjuna's refutation of 生生 two thousand years ago: a system cannot complete an account of its own origin within itself. What is distinctive about the Buddhist approach is that it does not try to solve this predicament; instead, by revealing its necessity, it points to a deeper insight: the starting point is not inside the system, and not outside the system either; rather… 生 itself is a phantom without self-nature.

Three: to loosen the fixation that everything needs a reason.

The ultimate conclusion of the 生生 debate — at least from the Mādhyamaka angle — is not "we need to find a 生生," but "we do not need 生生, because 生 itself is not substantially real." This conclusion is extremely radical, but also very healing.

We live in an age of over-rationalization. Everything must be given a reason. Love must have a reason, hatred must have a reason, choice must have a reason, existence must have a reason. But have you considered that the act of "giving a reason" itself also needs a reason? If it does not, then is it not itself a 生生? — a reason that needs no reason.

The wisdom of Buddhism is not to make you a person without reasons; it is to let you recognize: the most fundamental acts of life — arising, beginning, existing — need no reason. They are their own reason. This recognition is more direct than any project of "searching for the meaning of life."

Common Misreadings and Clarifications

Misreading one: "生生" means rebirth, life after life.

This is the most widespread and the most off-target misreading. In the treatises, 生生 is a strictly technical term, referring specifically to the secondary characteristic of the 生相 (utpāda-lakṣaṇa, characteristic of arising) — that is, the production of 生 itself. It is not about sentient beings being reborn life after life; it is about the structural question of how "arising" itself arises in the very instant any dharma arises. If you read the verses of the 《中論》 with "life after life" in mind, you will find them completely unintelligible.

Misreading two: "生生" means "endless cycling"; the scriptures are presenting a circular argument.

Some say that 生生 and the primary 生 producing each other is a circular argument, and the Buddhist texts themselves cannot get around it. This is inaccurate. Mutual production is precisely the opponent's position that the treatise sets up in order to refute it — it is not the treatise's own claim. The Sarvāstivādins set up mutual production to avoid infinity; the Mādhyamikas point out that mutual production itself is equivalent to infinity — because each "production" within the mutual relation still needs to explain how it itself is produced. A circular argument does not solve the problem; it merely hides it.

Misreading three: the Sarvāstivādins established 生生 simply in order to declare 生, 住, and 滅 to be substantially real.

This is only half right. The Sarvāstivādins do indeed hold that 生, 住, and 滅 are real dharmas, and therefore need secondary characteristics to mark the conditionedness of the primary characteristics themselves. But the 《俱舍論》's formulation is more nuanced: 「生能生所生,非離因緣合」— although the function of the 生 characteristic is real, it does not exist independently of causes and conditions. So the Sarvāstivāda position is not simply "生 is real"; it is "the function of 生 is a conditioned reality" — the function is real, but not separable from dependent origination. This differs from the stance of the 經部師 (Sautrāntikas), who hold that characteristics such as 生 are fundamentally empty, mere conventional designations.

Misreading four: the Mādhyamaka refutation of 生生 is meant to say "nothing exists."

This understands the Mādhyamaka "refutation" as nihilism. When Nāgārjuna refutes 生生, he refutes "生 has 自性 (svabhāva, self-nature)" — that is, that 生 can establish itself independently without depending on other conditions. He is not saying "there is no 生"; he is saying "生 is dependently originated, not self-natured." The result of the refutation is not "nothing" but 空 (śūnyatā, emptiness) — emptiness is not absence, but the absence of independent self-nature. When the lamp simile is refuted, it is not that "there is no lamp in the world"; it is that "the lamp's self-illumination and other-illumination cannot be established by the lamp as an isolated thing on its own."

Misreading five: understanding "生生" as "生生不息" (ceaseless production).

生生不息 is a term from the context of Chinese philosophy, referring to the cosmos ceaselessly creating and continuing. The 《周易》's 「生生之謂易」 speaks of the unceasing continuity of change. This is entirely different from the "secondary characteristic that allows the 生 characteristic to arise" in the Buddhist scriptures — that concept which is logically impossible to establish and is repeatedly refuted by Nāgārjuna. The former affirms the continuation of life; the latter reveals the self-grounding predicament of 生 itself. To conflate them is to treat "proof" and "disproof" as the same thing.


The concept of 生生, repeatedly analyzed and refuted layer by layer in the two treatises, points ultimately not to an answer but to an insight: 生 itself cannot ground itself. Every beginning, before it begins, has no "self" with which to begin; after it begins, it no longer needs to begin. That moment of "currently beginning" is precisely the place that is neither on this shore nor on the far shore.

Look at your life again with this lens: what you are doing right now, your existence at this moment, everything about you right now — their 生 does not need another 生 to drive them. They have simply arisen. You do not need to find a deeper reason for your own existence, because the very act of "looking for a reason" is itself an arising that needs no reason.

This is what 生生 ultimately tells you: that which you think needs to be explained is precisely what cannot be explained; and that which cannot be explained is precisely itself.

1. 定义与核心要义

「生生」(janmajanma)在《中論》与《十二門論》的相关论辩中,是有为法之「生」的复相或次生,并非泛指众生跨越生世而反复受生。两论皆先将一法生起时的结构分为七法,即法之自体与生、住、灭、生生、住住、灭灭;其中最初之生称「本生」,相对于本生而立的复相称「生生」。论辩所检验的核心,是本生与生生被设定为互相产生时,能否避免先后倒置、自体未成及无穷递推等困难。

2. 主要阐述

两论所述的基本设定相同:一法起时,七法同时成立;本生除自身外能生其余六法,生生则能生本生,而本生又能生生生。住住、灭灭与本住、本灭之间,也依此模式说明。立此结构的一方以本生与复相辗转相生,解释生、住、灭三相虽为有为法,却不必为每一相再无穷增立新相。

这一互生关系首先被概括为:生生所生者生于本生,本生所生者又还生于生生,因而二者各为对方的能生与所生。 随后的论难则从两个方向展开。

第一,若生生能生本生,生生自身既由本生而起,便须说明依本生而有者如何反过来产生本生;若否认本生能生生生,生生又失去自身的出生根据,更不能产生本生。

第二,若本生能生生生,而本生自身又须从生生而生,同样形成所依尚未成立却先产生能依者的困难。《中論》又说,生生本应生本生,但生生尚无自体,不能有生本生的作用;《十二門論》则着重指出,本生尚未生起,不能先产生生生,再由生生回头产生本生。

若将作用时点改为「生生正在生时」,困难仍未消除:正在生起的生生尚未成就自体,故不能产生本生;反过来,本生正在生时亦尚未有,不能产生生生。 《十二門論》还记载以灯为喻的答辩:如灯燃烧时能够自照、照他,生生亦可在生时自生并生本生;原文随即以「是事不然」否定此答,继续破斥其成立条件。

归结而言,若每一生又须由另一生使其生起,便形成无穷递推;若生不待他生而能自生,则一切法皆应自生,而原文判定事实并非如此。

3. 不同部类与译本的表述差异

《中論》与《十二門論》同属中观部,现有材料未呈现同经异译本,因而无异译词形可供对勘。两论术语与论证次序高度相近,但表述重点略有不同:

《中論》以「自體(一法)、生、住、滅、生生、住住、滅滅」列举七法,明确说「本生除自體,能生六法」,并以成组偈颂依次质难生生生本生、本生生生生,以及二者在「生時」能否起作用;其归纳又明言别有一生则堕无穷,无他生而自生则一切法皆应自生。

《十二門論》相应列作「法、生、住、灭、生生、住住、灭灭」,以「法」统摄所生法自身,并出现「生生生已」「是生生生时」等连续字形。依其所在论句,这些形式表示「生生」这一复相已经生起或正在生起,不是「生生世世」之义。该论另保存灯喻答辩及「是事不然」的驳语,使论辩形式更为显明。

两论均以「本生」称基本之生,以「生生」称其复相;材料中未见一论作「五阴」、另一论作「五蕴」一类实体不同而译名有别的情形。

4. 与相关概念的关系

「本生」是与生生最直接相对的概念:本生为最初或基本之生,生生为针对本生而设置的复相;二者的互生关系正是论难对象。 「住住」与「灭灭」分别是住、灭的复相,与生生共同构成七法中的三种复相;两论说明住、灭亦可依本生与生生的结构类推。

「生、住、灭」是有为法三相,生生不是三相之外另一个独立的轮回范畴,而是对生相再立的生相。「自体」或「法」则指七法结构中为诸相所表征的那一法;论中所谓生生尚未有自体,正用来否定它在自身未成时已有能生作用。 「无穷」是复相设置所欲避免、又在论难中重新显出的后果:若生须更生,层层追求其能生者,即无从终止。

5. 代表性原文引用

《中論》:「生生之所生,生於彼本生,本生之所生,還生於生生。」

《中論》:「若謂是生生,能生於本生;生生從本生,何能生本生?」

《中論》:「若謂是本生,能生於生生;本生從彼生,何能生生生?」

《中論》:「若生生生時,能生於本生;生生尚未有,何能生本生?」

《中論》:「若本生生時,能生於生生;本生尚未有,何能生生生?」

《十二門論》所存论述亦以生生与本生彼此相生为设定,并就「生生生已」「是生生生时」等情形审查其自体与生用是否成立。

阿毘達磨俱舍論T1558 · 毘曇部

《阿毘達磨俱舍論》以「四本相」與「四隨相」之對偶結構論述「生生」概念。本相即生、住、異、滅四種有為相,隨相則為生生、住住、異異、滅滅四者。論中明言:「諸行有為由四本相,本相有為由四隨相」,即一切有為法由本相標記其生滅流轉,而本相自身亦屬有為,復由隨相標記之。生生之定義,即「於九法內唯生本生」——當一法生起時,并其自體共有九法俱起(自體為一,本相四、隨相四共八),本相之「生」能生其餘八法,而隨相之「生生」唯能生本相中之「生」一法。論以雌雞為喻:「有生多子有唯生一」,本相生八法如雞生多子,生生唯生一法如雞唯生一子,二者力用有廣狹之別而同為實有功能。

此說之要旨在於化解「展轉無窮」之難:若本相亦是有為而需隨相標記,隨相復需隨相,則成無窮過。論以「四本四隨於八於一功能別故」答之——本相一一於八法有用,隨相一一於一法有用,功能既有分齊,隨相唯四即足,不須更立第五層相,故「無無窮失」。

論中又載經部師之質疑:「何緣如是分析虛空?非生等相有實法體如所分別。」經部師謂生等相無決定現量、比量或至教量證其實有,不應執為離法別有之實體。有部則引契經「有為之起亦可了知,盡及住異亦可了知」為據,並釋經意云:世尊為破愚夫於行相續執我我所,故說三有為相以顯相續體是有為、是緣生性,「非顯諸行一剎那中具有三相」。論更就相續義別釋:「諸行相續初起名生,終盡位中說名為滅,中間相續隨轉名住,此前後別名為住異。」此處以相續之前後分位說生住異滅,與剎那實有之分析互為表裏。

末以頌結:「生能生所生,非離因緣合。」明生相之作用在於生起所生之法,然此生用非離因緣和合而獨存,必待因緣具足方有能生所生之關係。

就術語形式言,本論固定使用「本相」與「隨相」一對名目,以「生生、住住、異異、滅滅」為隨相之全稱,以「四本四隨」為省稱,以「於八一有能」概括功能差別。此套術語為《俱舍論》有部義之特有表述。

中論T1564 · 中觀部

《中論》論「生生」,係於有為法三相(生、住、滅)之自我指涉難題中展開。論中先述敵宗之立:一法生時,通自體共七法俱生——一法、二生、三住、四滅、五生生、六住住、七滅滅;其中「本生」除自體外能生其餘六法,而「生生」能生本生,本生亦能生生生,以此互相生而謂三相雖屬有為卻不墮無窮。敵宗偈頌總括其旨:「生生之所生,生於彼本生,本生之所生,還生於生生」,即生生與本生展轉互生,構成封閉之生起鏈。

龍樹之破斥分數層進逼。第一層,就互生之方向質疑:若謂生生能生本生,則生生既從本生而出,云何反能生本生?長行釋云:生生從本生生,即不名從本生生者反生本生,因果方向相違。反向亦然:若謂本生能生生生,則本生既從生生生,云何能生生生?長行更詰:生生未有自體,何能生本生?是故本生不能生生生。第二層,就「生時」之剎那詰難:敵宗轉計生生正生之時(非先非後)能生本生;龍樹破云:「若生生生時,能生於本生;生生尚未有,何能生本生?」——生生於其自身正生之際尚未有體,無體則無能生之用。同理,本生生時亦尚未有,何能生生生。第三層,以無窮過收束:若生生時能生彼本生,則此「生」又復誰能生之? 互生之說既不能免無窮,則敵宗所許「非無窮」之旨自壞。

就術語形式言,《中論》以「生生」與「本生」對舉,為其獨特用詞。「本生」指有為法自體之正生(即三相中之「生」),「生生」指生此本生之第二層生;復有「住住」「滅滅」與之平行。此處「生生」非泛指相續世代之生,而是專指有為相自我生起之第二序概念,屬論辯語境下之技術術語。全段以偈頌與長行(青目釋)交替推進,偈立難題,長行逐句釋破,為《中論》觀三相品之典型論式。

十二門論T1568 · 中觀部

《十二門論》以「生生」與「本生」之互生關係為核心論題,在〈觀三相門〉中予以破斥。論中先述敵宗(有部)之立義:法生時,通自體七法共生——法、生、住、滅、生生、住住、滅滅;其中「本生」除自體外能生六法,而「生生」能生本生,本生還生生生,以此互生機制令三相雖是有為而不墮無窮。偈頌概括此互生結構為:「生生之所生,生於彼本生;本生之所生,還生於生生」。

龍樹菩薩之破斥分數層遞進。第一層,就互生之循環發難:若生生能生本生,而生生自身從本生而來,則生生何能反生本生?第二層,就單向生發發難:若謂生生能生本生而本生不生生生,則生生既無所從來,何能生本生?第三層,反向就本生發難:若謂本生能生彼生生,而本生從彼生生而來,則本生何能生生生?

第四層深入「未生」之難:生生之法應生本生,故名生生;然而本生實自未生,云何能生生生?若謂生生生時能生本生,則生生自體尚未生,不能生本生。偈頌重申:「是生生生時,或能生本生;生生尚未生,何能生本生?」 論文明言:「而是生生自體未生,不能生本生」。

第五層破燈喻:敵宗以「如燈然時,能自照亦照彼」為喻,謂生生生時能自生亦生彼本生。論主直斥「是事不然」,不許燈喻可成。

術語形式上,本論固定以「生生」與「本生」對舉,「本生」即有部所立四相中之「生相」本身,「生生」則為生相之生(使生相得以生起者)。七法並列時稱「生生」「住住」「滅滅」,皆以重字表示「使某相生起之生」,此為本論所據有部之特有術語結構。全論以歸謬法(prasaṅga)逐層追破互生、單生、未生、自生諸計,結論指向生生與本生之互生架構不能成立,有為三相非實有。
