What This Concept Is About
"有無二邊" (the two extremes of existence and non-existence) are the two extremes posited by the Madhyamaka (中觀) tradition of Buddhism regarding "misapprehending the true meaning of all dharmas." On one side is reification into existence (增益為實有, samāropa) —grasping at things that arise through dependent origination and lack fixed self-nature, insisting "it is inherently thus, it is eternally thus, it has an intrinsically real essence." On the other side is negation into total non-existence or non-being (損減為全無, apavāda) —sweeping away everything that arises from causes and conditions as "originally nothing at all; everything is illusion; even karma and its results are false." The two sides grasp in different ways, but both are forms of "fixation" (定)—pinning down flowing, condition-arisen phenomena with a fixed judgment at some location.
These two extremes are not isolated; they naturally slide into two deeper worldviews. Grasping at existence leads to falling into the view of eternalism (常見, śāśvatadṛṣṭi) —believing there is some eternal, unchanging entity. Grasping at total non-existence leads to falling into the view of annihilationism (斷見, ucchedadṛṣṭi) —believing everything ultimately comes to nothing, and even karma, cultivation, and liberation from suffering have no real meaning. The line in the *Mūlamadhyamakakārikā* (*中論*, T1564) that has been quoted again and again by later generations makes this connection very clear: 「定有則着常，定無則着斷。是故有智者，不應着有无。」 *"Fixation on existence leads to attachment to eternalism; fixation on non-existence leads to attachment to annihilationism. Therefore, the wise should not attach to existence or non-existence."* The single word "定" (fixation) is the key to this concept—it does not mean we cannot speak of "existence" or "non-existence" at the conventional level, but rather that we should not turn them into ultimate, decisive judgments.
The most common pitfall in understanding this concept is interpreting "transcending the two extremes" as "finding a middle value between existence and non-existence." This is precisely what the *Illuminating the Intent of the Madhyamakāvatāra* (*入中論善顯密意疏*) specifically warns against—you cannot, because you have refuted existence and refuted non-existence, then establish a separate, really-existing "middle way" or "middle ground." That "really-existing middle" is itself a third extreme view. The middle way is not an entity; it is the state of freedom from attachment disclosed by selflessness (無自性), emptiness (空), and conventional designation (假名施設) . The *Mūlamadhyamakakārikā* states clearly: 「離有無二邊，故名為中道」—"Because it is free from the two extremes of existence and non-existence, it is called the middle way." The middle way is the *result* of "being free from," not something "established."
Next, we must clarify the precise relationship between "emptiness" (空性, śūnyatā) and the two extremes. Correctly penetrating emptiness is precisely simultaneously not falling into either extreme: on the one hand, "not falling into the extreme of negating the conventional"—one does not deny that karma and its results can be established like reflections, simply because dharmas lack self-nature; on the other hand, "not falling into the extreme of reifying the ultimate"—one does not reify the ultimate truth, thinking there is an eternal emptiness-essence behind "emptiness." Mistaking emptiness as "all dharmas are totally non-existent" or "entirely non-being"—this is not penetrating emptiness; this is grasping emptiness as an annihilationist wrong view. The *Illuminating the Intent of the Madhyamakāvatāra* directly judges such false conceptualization as a wrong view (邪見). In other words, "emptiness is also empty" (空亦復空)—emptiness itself should not be grasped at as something substantially real.
The *Illuminating the Intent of the Madhyamakāvatāra* gathers the entire meaning of the middle way into one extremely concise statement: 「二諦俱無自性故，彼等非斷亦非常。」*"Because both the two truths lack self-nature, they are neither annihilation nor eternalism."* Both the conventional truth (世俗諦, saṃvṛti-satya) and the ultimate truth (勝義諦, paramārtha-satya) lack self-nature, but this "lacking self-nature" does not equal "total non-existence"—therefore it cannot be judged as annihilation; nor, because it has a level that can be cognized and expressed, can it be grasped as eternally abiding. This is the core tension of the middle way's meaning, and also the reason why the concept of the two extremes of existence and non-existence is so profound.
The *Mūlamadhyamakakārikā* also contains a subtler investigation—it divides extreme views into four propositions: "the extreme of existence" (有邊), "the extreme of non-existence" (無邊), "both the extreme of existence and non-existence" (亦有邊亦無邊), and "neither the extreme of existence nor non-existence" (非有邊非無邊). These four judgments are not independently established concepts, but are established relative to each other (相待而立) —"non-existence" is called "non-existence" precisely because it is opposed to "existence"; just as "short" is short because there is "long" opposed to it. Once the composite item "both existence and non-existence" is refuted, the "neither existence nor non-existence" that depends on it also loses its basis of relative dependence. This fourfold investigation tells us: grasping at extremes is itself a crystallization of a thought-structure, and every link in that structure depends on other links to be established—no single item is self-sufficiently real.
Finally, one frequently overlooked distinction must be remembered: the *Illuminating the Intent of the Madhyamakāvatāra* reminds us that the "permanence" and "annihilation" refuted here are "the permanence and annihilation that are the danger-zone of what is to be abandoned (所治品險處之常斷) "—permanence and annihilation as the dangerous extremes of extreme views. This differs from "permanence" and "annihilation" in ordinary contexts: unconditioned dharmas (無為法, asaṃskṛta-dharma) are called permanent; an arhat has cut off the continuum of birth-and-death. These are not within the scope of what is refuted here. When we say "grasping at existence falls into the eternalist view," what is refuted is the decisive grasp of dharmas as substantially existent, not every concept that happens to carry the word "permanent."
Walking Through It in Everyday Life
Let us walk through concrete scenarios one by one, to see how the two extremes of existence and non-existence recur repeatedly in contemporary life.
Scenario One: After a breakup, the other person has read your messages and not replied.
In the first week, you might grasp at "existence"—"He must still have feelings for me, he's just not ready yet, I'll wait for him." You solidify a relationship that has already changed with conditions, where both parties' feelings have already shifted, into "he essentially still loves me"—this is reification into existence, judging a flowing condition-arisen relationship as an unchanging entity.
After a few weeks, with friends all saying "he's not worth it," you might suddenly flip to the other side—grasping at "non-existence"—"My entire relationship was fake, he was deceiving me from start to finish, and I never really loved him either; everything is meaningless." You sweep the attachment that really occurred, the time you shared, your own growth, all into "total non-existence"—this is negation into total non-existence.
Both extremes cause suffering. The first makes people stuck, unwilling to let go; the second makes people nihilize everything and unable to see why they are in pain. If you can relax a little on both sides—neither solidifying the other person into "an essence that will love me forever," nor judging the entire experience as "all illusion"—you begin to approach the middle way's way of seeing: his closeness then was real, his distance now is also real; these are all changes in conditions. You do not need to pin it down with "definitely exists" or "definitely does not exist."
Where people most often map it wrong: thinking the "middle way" means "he loves me halfway, he doesn't love me halfway"—this turns the middle way into "compromise" or "middle value." The *Mūlamadhyamakakārikā* precisely warns against additionally grasping a substantially real middle. The middle way is not the mathematical average of "taking half from each side," but the loosening of the grasping at both extremes themselves.
Scenario Two: Anxiety about a child's future.
Parents often slide into the "existence" extreme here: "My child must get into a good school, must find stable work, must marry and have children—this is 'the life he ought to have.'" Presupposing a "correct, substantially real" template for a living, constantly condition-changing life—this is reification into existence.
When anxiety reaches its peak, they flip to the "non-existence" extreme: "Anyway, effort is useless; the times are changing so fast, planning anything is meaningless; the child can do whatever he wants." Sweeping karma, dependent origination, and the power of education entirely into "total non-existence"—this is negation into total non-existence.
The middle way's seeing is: the child is a life that arises from causes and conditions, without fixed self-nature. The conditions of education, the conditions of family affection, his own conditions—all are operating, but there is no "what he must become" that is substantially real. What we can do is to do our best to plant good causes and conditions in each present moment, but we need not and cannot lock in the concrete appearance of the result. This is neither indulgence nor control; it is seeing truthfully that every causal factor is operating, but no single factor can guarantee an eternally unchanging result.
Scenario Three: Self-evaluation—"I am not good enough."
Many people grasp the "existence" extreme—solidifying a single mistake or a low period into "I just can't do anything; my essence is failure." The "I" here is made into an entity with fixed self-nature, and this entity is assigned the eternal label of "failure."
But there is also an inverted "non-existence" grasping—a kind of spiritualized self-dissolution: "I am actually nothing at all; there is no real self; everything is empty, so making mistakes doesn't matter, effort doesn't matter either." This is a typical case of mistaking emptiness for "total non-existence"—understanding "dharmas lack self-nature" as "even basic responsibility and agency can be discarded." This is precisely the wrong view warned against in the *Illuminating the Intent of the Madhyamakāvatāra*: falsely conceptualizing conditioned dharmas as non-existent (妄計諸行非有).
The middle way's seeing is: there is no "fixed, unchanging, eternally failing self," but this does not mean present choices are unreal or unimportant. Karma and its results are established like reflections—the level of reality where you can see, take responsibility for, and change things cannot be swept away by a single phrase "everything is empty."
Scenario Four: Reactions to social events—witnessing injustice.
Some people slide into the "existence" extreme—"This world is just bad; its essence is depraved; human nature is inherently evil; the world will never get better." Solidifying a condition-arisen, changeable social state into an entity that is "essentially thus"—this is eternalist grasping, carrying deep despair.
Others slide into the "non-existence" extreme—"Anyway, everything is the same; doing anything is meaningless; pursuing fairness and justice is also illusion; individuals cannot change anything at all." Sweeping the power of karma and dependent origination, the possibility of accumulated action by countless individuals, entirely into "total non-existence"—this is annihilationist nihilism.
The middle way's seeing is: this era is indeed full of injustice, but "full of injustice" is not its eternal essence; individual action is indeed limited, but "limited" is not "totally nonexistent." You can do, in each present moment, what your conditions make possible. This "doing" is real. Whether the result reaches the "good" you expected is not something you can lock down with "definitely exists" or "definitely does not exist."
Scenario Five: Two extremes regarding "practice" and "spirituality."
Some people grasp "existence"—making a particular state, enlightenment, or supernatural power into a substantially real goal, thinking "I must reach that state; that is what is real." This solidifies practice into an entity to be arrived at.
Others grasp "non-existence"—"Since everything is empty, practice and not practicing are the same; anyway, there is no real liberation to be obtained; pursuing liberation itself is attachment." This is a typical case of understanding emptiness as "total non-existence." The *Illuminating the Intent of the Madhyamakāvatāra* directly judges this "false conceptualization of conditioned dharmas as non-existent" as a wrong view.
The middle way is: practice is not about arriving at a substantially real "state of enlightenment," but this does not mean no real transformation can occur. The lessening of afflictions, the growth of wisdom, the sharpening of awareness of others' suffering—these are real functions arising from causes and conditions, not illusions. But neither is there an eternal, substantially real "perfect state" waiting there for you to arrive at.
Why Contemporary People Need It
The first reason: both extremes—existence and non-existence—are intensifying in contemporary life.
On the one hand, the pressure of the "existence" extreme is unprecedented. The entire consumer culture and personal-brand culture constantly tell us: you need a fixed, presentable, quantifiable "authentic self"—your personality test results, your professional title, your social media image, your life narrative. This demand that "I must be a really-existing thing" naturally slides into reification into existence. And when this "really-existing self" is threatened—unemployment, breakup, health problems—the suffering becomes especially acute, because it is not just an event occurring, but the "collapse" of the entity "I."
On the other hand, the temptation of the "non-existence" extreme is unprecedentedly widespread. In information overload, in the loss of a sense of meaning, in the burnout of "having seen everything," "everything is empty, pursuing anything is meaningless" becomes an attitude that is extremely easy to slide into. Various versions of nihilism, cynicism, and certain variants of "Buddhist-style" detachment—if examined closely, many are misreadings of emptiness, hearing "dharmas lack self-nature" as "nothing matters."
The concept of the two extremes of existence and non-existence provides a framework for dismantling both pressures simultaneously: your self is not substantially real, but you are not "nothing at all"; the world is not eternally fixed, but neither is it entirely illusory. The precision of this tension is what makes this concept especially valuable in the contemporary context.
The second reason: what we need is not "compromise," but seeing the structure.
In contemporary culture, many people hear "middle way" and think it means "each side steps back a bit," "rational balance," "don't be extreme." This is a flattened reading of the middle way. The middle way in the *Mūlamadhyamakakārikā* is not compromise; it is a seeing of the grasping structure itself—the ability to see that "fixation on existence" and "fixation on non-existence" are two faces of the same grasping mechanism, different expressions of the same impulse to pin down what is flowing. Once you see this structure, you are not "finding a balance point between two extremes," but loosening the impulse to "fix" itself. This is a qualitative change, not a quantitative one.
The third reason: the contemporary fragility of causality.
The *Illuminating the Intent of the Madhyamakāvatāra* repeatedly emphasizes the danger of "negating the conventional extreme" (損減世俗邊)—that is, denying karma and its results, denying causality. In the contemporary world, the very concept of causality is under assault from many directions: the randomness of algorithms, the popular misreading of quantum indeterminacy, probabilistic thinking diluting "necessary outcomes," and various "law of attraction" success philosophies distorting karma into "think it and it will happen"—all of these make "causality is real" difficult to say. But the Madhyamaka has never denied causality; what it says is: causality is real at the level of dependent origination (the conventional truth), but causality itself has no eternal, unchanging self-nature (the ultimate truth). Whether one can, while acknowledging "everything lacks self-nature," avoid sliding into "karma is also false"—this is one of the most urgent applications of the concept of the two extremes of existence and non-existence in the contemporary world.
Common Misreadings and Clarifications
Misreading One: Thinking "transcending the two extremes" means "compromise" or "balance."
Clarification: The middle way is not an average, not "he is half right and I am half wrong," not a mild relativism. It is the loosening of the act of "fixation" itself—no longer attempting to pin down condition-arisen things with an ultimate judgment. The *Illuminating the Intent of the Madhyamakāvatāra* specifically warns: one must not establish a substantially real "middle." That "really-existing middle" is itself a third extreme view.
Misreading Two: Thinking "emptiness" means "nothing at all."
Clarification: This is the wrong view repeatedly warned against in the *Illuminating the Intent of the Madhyamakāvatāra*. Understanding emptiness as "all dharmas are totally nonexistent" or "entirely non-being," and using this to deny causality, deny karma and its results, deny the real function of practice—this is grasping emptiness as annihilation, not penetrating emptiness. The treatise states clearly that although the words "non-existence" (無) and "non-being" (非有) differ, the "aspect of non-existence" they take as object is no different; false conceptualization of conditioned dharmas as non-existent is judged as a wrong view. The correct expression of emptiness should be "emptiness is also empty" (空亦復空)—emptiness itself should not be grasped at as something substantially real.
Misreading Three: Thinking the refutation of "permanence" and "annihilation" applies to all contexts.
Clarification: The *Illuminating the Intent of the Madhyamakāvatāra* reminds us that the "permanence" and "annihilation" refuted here are "the permanence and annihilation that are the danger-zone of what is to be abandoned"—the danger-zone of extreme views. This is not the same as unconditioned dharmas being called permanent, or an arhat cutting off the continuum of birth-and-death, in ordinary contexts. When readers encounter the words "permanent" (常) and "annihilation" (斷) in texts, they must judge from context whether they are being used in the sense of "extreme views," so as not to mistake everyday usages of "permanent" and "annihilation" as the objects of refutation here.
Misreading Four: Thinking "dharmas lack self-nature" means "everything is unreal."
Clarification: "Dharmas lack self-nature" means dharmas have no eternal, unchanging, independently self-existing essence—not that dharmas' functions at the conventional level are false. The "emptiness is also empty" in the *Mūlamadhyamakakārikā* means that emptiness itself is also without self-nature, and therefore cannot be reified; but the causality, karmic retribution, and dependent origination of the conventional truth are a reality "established like reflections" (如影像般成立)—this layer of reality cannot be swept away by the single phrase "lack self-nature." 「二諦俱無自性故，彼等非斷亦非常」—both truths lack self-nature, but this does not mean both truths are annihilation.
Misreading Five: Thinking that understanding the two extremes of existence and non-existence equals enlightenment.
Clarification: The two extremes of existence and non-existence is a conceptual framework, an analytical tool for dismantling erroneous grasping. Understanding its conceptual structure is still a long way from actually loosening the grasping at "fixation on existence" and "fixation on non-existence" in the present moment of each thought. Conceptually understanding "one should not attach to existence or non-existence" is one thing; whether, in the midst of a breakup, unemployment, or the loss of a loved one, one can actually avoid falling into "total non-existence" or "it will be like this forever"—that is an entirely different matter. This is also why this concept is connected with "cultivation" and "penetration" in both treatises—it is a guide for actual practice, not an endpoint of knowledge.
Misreading Six: Treating the "middle way" as a specific philosophical position.
Clarification: The middle way is not "the Buddhist position is right, other positions are wrong," nor is it "Madhyamaka is superior to other schools." It is the dismantling of the structure of "grasping at extremes" itself—any thought system, as long as it turns its central claim into an ultimate judgment of "definitely exists" or "definitely does not exist," falls within the scope of this analysis. Madhyamaka's attitude toward itself is the same—"emptiness is also empty"; the "emptiness" spoken of by Madhyamaka should not itself be grasped at as something substantially real.
Finally, what should be said is this: the concept of the two extremes of existence and non-existence sounds like an abstract philosophical topic, but it actually points to the two most common slides our minds make when facing the world in each present moment—either desperately clinging, or utterly letting go. The training of the middle way is not about finding a clever balance between the two, but about cultivating a way of seeing: what you cling to and what you let go of are neither what you think they are. This seeing is not read from books; it is accumulated by recognizing and loosening, one by one, each moment when a thought of "definitely exists" or "definitely does not exist" arises. This concept is only a map, not the journey itself. But without a good map, the journey is hard to go far.
