Definition
Emptiness (śūnyatā) is the central doctrine of Madhyamaka philosophy: all phenomena are empty of intrinsic nature (svabhāva, རང་བཞིན་). This does not mean non-existence. It means, rather, that nothing possesses independent, self-sustaining existence; everything arises dependently (pratītyasamutpāda). As Candrakīrti states in his commentary on MMK 24:7, the meaning of “dependent origination” is precisely the meaning of “emptiness” — yet the meaning of “non-existence” is not the meaning of “emptiness.”
The emptiness of emptiness (śūnyatāśūnyatā) is a necessary refinement. Emptiness itself is not a substantial, ultimately real property; it too is empty. This stops emptiness from hardening into a reified metaphysical view (dṛṣṭi), which is exactly what Nāgārjuna warns against in MMK 13:18.
Interpretations
Westerhoff’s “emptiness as conventional corrective”: Westerhoff in westerhoff-madhyamaka-2009 argues that the theory of emptiness is not an ultimately true description of mind-independent reality. Its purpose is to combat the wrong ascription of svabhāva to phenomena, working as a corrective for a mistaken cognition. His analogy: an empty pot does not normally need to be described as “free of white mice,” but if someone hallucinates mice on it, the negative description becomes useful. Without the error, the corrective is unnecessary. Emptiness therefore does not exist “from its own side,” and it is not causally produced together with its object (unlike the empty space in a cup). A mind not prone to superimposing svabhāva would have no need to conceive of objects as empty. This entails rejecting correspondence truth in favour of truth as warranted assertibility: there can be no “ultimate truth” describing how things really are independent of conceptual frameworks. Even emptiness is only conventionally true (pp. 44–45, 219–222). The position sits close to the Geluk mainstream, but it draws out implications that traditional commentators leave implicit.
Nihilist readings: A long line of interpreters has understood emptiness as equivalent to non-existence (abhāva), producing a nihilist reading of Madhyamaka. The line runs from non-Buddhist Indian critics (Uddyotakara, Kumārila, Śańkara) through Yogācāra critics (Asańga, Vasubandhu) to modern scholars (Burton, Wood, early de la Vallée Poussin). Westerhoff in westerhoff-nihilist-interpretation-2016 argues that the charge points to real features of the system but fails when it takes nihilism to entail denial of appearances, denial of efficacy, or moral nihilism.
Siderits’s three-options taxonomy and semantic non-dualism: In siderits-buddhism-philosophy-2007 Ch 9 (pp. 180–207), Mark Siderits sets out a systematic analytic taxonomy of the interpretive options that remain once Madhyamaka’s arguments are granted. There are three: (a) metaphysical nihilism, “ultimately nothing whatever exists”; (b) “reality is ineffable,” the view that what is ultimately real transcends conceptual capacity (Yogācāra adopts a variant); and (c) semantic non-dualism, the view that the very idea of an ultimate truth, in the Abhidharma correspondence-theoretic sense, is incoherent. Option (a) is blocked by Nāgārjuna’s own argument at MMK V.6–8 (“when the existent is not real, with respect to what will there come to be non-existence?”). Option (b) is blocked by MMK XIII.7–8, the purgative simile that “those for whom emptiness is a [metaphysical] view, they have been called incurable.” Option (c) is the only remaining live one, and it is positively supported by the emptiness-of-emptiness verses MMK XXII.11 and XXIV.18 (prajñaptir upādāya). The apparent paradox of “the ultimate truth is that there is no ultimate truth” dissolves once two senses are disambiguated: ultimate truth₁ is a fact that must be grasped to attain enlightenment; ultimate truth₂ is a statement corresponding to the ultimate, mind-independent nature of reality. The doctrine of emptiness then reads “the ultimate truth₁ is that there is no ultimate truth₂.” Conventional truth survives without correspondence-grounding through the analogy of paper currency taken off the gold standard: value (truth) derives from a role in human practices, not from backing by intrinsically natured items.
Semantic non-dualism is thus a fourth substantive reading, distinct from Tsongkhapa’s med dgag of bden grub, from Gorampa’s two-level ultimate, from Westerhoff’s deflationary antirealism, and from the early-Western deflationary line (Sprung 1979 / Kalupahana 1986 / Burton 1999). It comes closest to Sprung’s Wittgensteinian formula, “the higher truth, in so far as it is a theory, falls within the lower truth.” Unlike Sprung, though, it explicitly defeats both the nihilist and the ineffabilist readings through Nāgārjuna’s own arguments, rather than by a Wittgensteinian language-game move.
Burton’s nihilism argument: Burton in burton-emptiness-appraised-1999 provides the most sustained modern case for the nihilist reading. Understood in the Abhidharma context, he argues, the universal absence of svabhāva means that all entities are entirely conceptually constructed (prajñaptimātra). Conceptual construction requires both unconstructed material and an unconstructed constructor. Since Nāgārjuna denies any unconstructed existent, nothing can exist. Burton accepts that Nāgārjuna did not intend nihilism, but he argues that the philosophy entails it. He adds that even on a non-nihilist reading, Nāgārjuna’s equation of analysable existence with conceptually constructed existence amounts to “excessive ontological parsimony.” He grants that the dGe lugs pa solution (emptiness is true but does not truly exist) is “the most ingenious attempted solution,” but he does not engage it fully, because his method excludes later commentarial elaboration.
Candrakīrti’s position: In the Prasannapadā on MMK 18:7, Candrakīrti concedes an “essential identity” (vastutas tulyatā) between what the Mādhyamika and the nihilist say about what does not exist. He insists, however, on a vast epistemological and soteriological difference between the two proponents. His “theft” analogy makes the point: two men say the same thing (“he is a thief”), but one speaks from knowledge and the other from malice.
Garfield’s emptiness of emptiness: In garfield-fundamental-wisdom-1995, Garfield makes the emptiness of emptiness the architectural key to the whole MMK. He reads it as “harmonizing with Candrakīrti’s” interpretation, present already in the opening chapter on conditions and only made explicit at 24:18. Emptiness is “not a self-existent void standing behind a veil of illusion comprising conventional reality, but merely a characteristic of conventional reality.” His worked demonstration comes in the 24:18 commentary: analyse the emptiness of a table and “we find nothing at all but the table’s lack of inherent existence… the emptiness is dependent upon the table and is therefore itself empty, as is the emptiness of that emptiness, and so on, ad infinitum.” Madhyamaka nominalism renders the apparent regress harmless. “Conventional” functions ontologically, as a mode of subsistence, not as a logical negation-operator that would cancel itself, so the iteration never collapses into “really, things are non-empty.” This is what saves the system “from falling into metaphysical extravagance.” Emptiness is wholly negative (Ch XIII): “not an essence that things have instead of whatever essence… they were thought to have — rather, it is the total lack of essence.” It is also emphatically anti-nihilist, by way of the twin-distortion thesis (24:16): “nihilism about one kind of entity is typically paired with reification of another.” Reifying the conventional requires reading emptiness nihilistically; reifying emptiness requires nihilism about the phenomenal world. Garfield’s reading converges with Tsongkhapa’s śūnyatāśūnyatā (above) and with Candrakīrti’s, reached in the analytic register.
He states the architecture a year earlier, and as an explicit reading-method, in garfield-dependent-arising-1994. There the emptiness of emptiness is “in embryo” in MMK Ch 1, which is why Nāgārjuna opens with causation; one must read Ch 1 through Ch 24, holding the emptiness of emptiness in mind, for the negations to read as self-consuming rather than nihilistic. As he puts it, “it is one thing to argue for the emptiness of some phenomenon simpliciter and quite another to argue for that emptiness with the emptiness of emptiness in mind.” His worked example is the motion chapter (MMK 2): read alone it “can appear unrelentingly nihilistic,” but read with the emptiness of emptiness imported from Ch 24, motion is recovered as a merely conventional, dependent relation. One caution about his register: his heavy Tractatus gloss on the apophatic verses (18:9) sits close to Sprung’s reading, so he supports the self-consuming negation but not the anti-quietist guardrail against it.
Tsongkhapa’s emptiness and dependent origination (via Jinpa): In jinpa-tsongkhapa-qualms-1999, Jinpa reconstructs Tsongkhapa’s deepest move: dependent origination is the content (don) of emptiness. By denying the conventional world of dependent origination, the “no-thesis” proponents reject the heart of Prāsaṅgika philosophy. “The very fact of dependence is the highest proof of the absence of intrinsic being.” To hold otherwise is “like a god turning into a devil” (lha bdud tu bobs pa). Both nihilists and essentialists share one false equation: existence = intrinsic existence. If something does not exist by means of intrinsic being, they conclude that it does not exist at all. Tsongkhapa argues that this binary is itself the root error.
Tsongkhapa’s position (in his own words): In Illuminating the Intent, Tsongkhapa argues that all phenomena are empty of intrinsic existence in the sense that they are posited through mere conceptualisation, like a snake imputed on a rope. Nothing exists “in its own right” (rang ngos nas). But this emptiness does not negate conventional existence: unlike the rope-snake, conventional phenomena such as vases do exist and are capable of effective functions. The distinction turns on whether conventions remain essential for everyday transaction. Emptiness is the ultimate nature of entities such as sprouts, obtained by the rational cognition that realises how things really are, yet it is “not established through its own essence.” Tsongkhapa gives six synonyms for what is negated: “true existence,” “ultimate existence,” “absolute existence,” “existence by virtue of essential nature,” “existence through intrinsic characteristic,” and “intrinsic existence.” The Prāsaṅgika negates all six. (From tsongkhapa-illuminating-intent-1418, Ch 9 and Ch 11.)
Tsongkhapa’s emptiness of emptiness (Ch 19): Treating the sixteen emptinesses at MA 6.179–223, Tsongkhapa anchors the śūnyatāśūnyatā doctrine in a careful distinction between two senses of svabhāva drawn from MMK XV.2: (i) intrinsic nature as the essence by which things exist, which is categorically rejected; and (ii) intrinsic nature as the absence of intrinsic existence, that is, emptiness, which is “the only true nature things have” and which is accepted. The accepted second sense does not relapse into essentialism, because emptiness is itself a non-implicative negation and is itself empty of intrinsic existence: “though emptiness is the ultimate truth, paradoxically, it has no ultimate existence — hence the emptiness of emptiness.” This is Tsongkhapa’s primary-text answer to the regress objection, and to the gzhan stong (གཞན་སྟོང་) charge that any “true nature that survives analysis” is an Absolute under another name. His position is that what survives analysis is precisely the absence of what was analysed away, and that this absence does not function as a foundation in the way that would re-enter the regress. (From tsongkhapa-illuminating-intent-1418, Ch 19, with the explicit “even emptiness is a conventional existent, not an ultimate existent” formulation in Jinpa’s introduction.)
Zhentong reading (Dolpopa/Tāranātha): The zhentong tradition fundamentally redefines what “emptiness” means. For Dolpopa, emptiness is not the mere absence of intrinsic nature in all phenomena (self-emptiness, rang stong, རང་སྟོང་), but a positive, truly existent reality — the thoroughly established nature (yongs su grub pa) — that is empty only of what is other than itself (adventitious defilements, conventionalities). Tāranātha clarifies: “although [something] is empty or is an emptiness, it is not necessary that it be empty of its own entity.” Pristine wisdom is called “emptiness” because it is empty of all proliferations other than itself, not because it lacks its own nature. Other-emptiness is an affirming negative (ma yin dgag), not a non-affirming negative; it includes positives, since ultimate Buddha-qualities are integral to the ultimate (see dolpopa-mountain-doctrine-1333 470). Dolpopa has his own two-emptiness terms: self-emptiness is “empty-emptiness” (a phenomenon empty of its own entity, hence a conventionality), and other-emptiness is “non-empty-emptiness” (the ultimate, empty of the other two natures but not of itself), MD 213, 252, 301. He criticises the rangtong position — that even the ultimate is empty of its own nature — for falling into the extreme of non-existence by leaving nothing truly established. (dolpopa-mountain-doctrine-1333; concise synthesis at taranatha-essence-other-emptiness-2007.)
Śāntarakṣita and Mipham’s Yogācāra-Madhyamaka emptiness: Śāntarakṣita establishes emptiness through the “neither one nor many” argument: entities that are neither truly singular nor truly plural cannot possess intrinsic being — “they are like reflections” (v. 1). The distinctive move is that this emptiness is reached in two steps. First, external objects are shown to be mind’s projections (Cittamātra); then mind itself is shown to lack intrinsic nature (Madhyamaka). The result is an emptiness that is “free from constructs and elaborations,” the actual ultimate (v. 71), distinguished from the approximate ultimate where emptiness is still cognised conceptually. Mipham argues that both Svātantrika and Prāsaṅgika arrive at this same actual ultimate; the difference between them is pedagogical, not a difference in what emptiness ultimately is. (From shantarakshita-madhyamakalankara.)
The two no-selves “of one taste,” and emptiness with the essence of compassion (Nyingma, via the Norbu Ketaka): the commentary on Bodhicaryāvatāra 9.40–56 — Mipham’s reading transmitted through Khenpo Kunzang Pelden — gives the universal-emptiness extension in its sharpest traditional form (see kunzang-pelden-nectar-manjushri-2007). Against the śrāvaka claim that liberation comes through personal no-self alone, “there is no difference at all between these two assertions of emptiness: that of the personal No-Self and that of the phenomenal No-Self.” The person is imputed on the aggregates, the aggregate-wholes (body, pot) are imputed on their parts, and “the only difference… lies in the thing considered to be empty.” The wisdom that uproots affliction is the realisation of phenomenal emptiness, of which personal no-self is “a specific instance, a lesser category… like the relationship between the genus tree and the species juniper.” On this reading, śrāvaka arhats who refuse the phenomenal no-self retain a non-afflictive ignorance and are not finally liberated until they enter the Mahāyāna (cf. Mipham’s MA 1.8 minority reading at mipham-introduction-middle-way-2002 Supplementary Discussion, section 9). The same chapter frames emptiness soteriologically: following Atiśa, “when emptiness is realized… great compassion arises. Emptiness possesses the essence of compassion” (BCA 9.1; vv. 151–167). Emptiness is taught for compassion.
Gorampa’s two-level ultimate truth: Gorampa distinguishes the quasi-ultimate (rnam grangs pa) — emptiness as the endpoint of rational analysis, which he argues is actually a conventional truth, since it is conceptually constructed — from the real ultimate (don dam mtshan nyid pa), which is ineffable and accessible only through yogic gnosis. The emptiness cognised through philosophical reasoning is therefore not yet the real ultimate truth. Gorampa charges that Tsongkhapa’s treatment of emptiness as a conceptually apprehended non-affirming negation grasps at emptiness as an object, which is itself a form of nihilism — not because it denies too much, but because it has not gone beyond conceptual proliferation. The authentic Madhyamaka position negates all four koṭis of the catuṣkoṭi without qualification. (From gorampa-distinguishing-views-1469.)
Kalupahana’s pragmatic emptiness: For Kalupahana, emptiness is not a metaphysical doctrine at all. It is a “view” (dṛṣṭi), but a view that must be identified with “the empty” (idaṃ śūnyam), that is, with concrete dependently arisen phenomena. “All this is empty” (sarvam idaṃ śūnyam) always retains the demonstrative “this”; Nāgārjuna never makes the absolutist statement “all is empty” (sarvaṃ śūnyam). Emptiness means that phenomena lack the substantial existence (svabhāva) asserted by the Sarvāstivādins; it does not point to a transcendent truth or a linguistically inexpressible reality. Those “possessed of the view of emptiness” (MMK 13:8) are those who reify it into an Absolute, divorcing it from the concrete phenomena it characterises. Kalupahana argues that if emptiness were “ultimate reality,” Nāgārjuna would have devoted at least one chapter to explicating it and its epistemological basis; instead, the concept is always parasitic on the denial of substance in particular phenomena. This is a thoroughgoing deflationary reading: emptiness is the absence of metaphysics, not a special metaphysical insight. (From kalupahana-mmk-1986.)
Ninth Karmapa’s freedom from elaborations: For the Ninth Karmapa, emptiness is a mere conventional label given to phenomena’s lack of establishment in any extreme elaboration. “All phenomena from form through omniscience are, from the outset, not established whatsoever as any extreme elaboration such as existent, nonexistent, arisen, ceased, permanent, impermanent, empty, not empty, true, or false.” The Karmapa’s three stages of analysis structure the role of emptiness: at “slight analysis” it is essential to determine that phenomena are empty, but at “thorough analysis,” even emptiness is transcended, and freedom from elaborations (niṣprapañca, སྤྲོས་བྲལ་) is the genuine Middle Way. This treats emptiness explicitly as a pedagogical tool for the second stage, not as the final destination. The Karmapa criticises Tsongkhapa’s approach as “partial emptiness” (nyi tshe ba’i stong pa nyid): by isolating “true existence” as the target of refutation rather than phenomena themselves, Tsongkhapa misses what sentient beings actually cling to. Gendün Chöpel corroborates the point: “you need to refute the vase; you need to refute the pillar.” (From karmapa-feast-fortunate-1578.)
Gorampa’s “neither existent nor non-existent”: The negation of existence does not imply the acceptance of non-existence (yod min med min). This contrasts directly with Westerhoff’s “consistent nihilism,” which accepts certain nihilist entailments. Gorampa would likely classify Westerhoff’s approach as another form of the proliferative grasping he critiques in Tsongkhapa. (From gorampa-distinguishing-views-1469.)
Gorampa’s three-fold Yogācāra emptiness analysis (transmitted from Red mda’ ba): as part of his refutation of zhentong, Gorampa transmits the Mahāyāna-internal three-fold emptiness drawn from the last three works of Maitreya and the texts of Asaṅga and Vasubandhu: (1) the emptiness of own-characteristic of the parikalpita (imaginary); (2) the not-as-it-appears emptiness of the paratantra (dependent); and (3) the essence-emptiness of the pariniṣpanna (thoroughly established). His argument is that, even on Yogācāra’s own terms, Dolpopa’s gzhan stong fails. The paratantra should still be empty of own-characteristic, which Yogācāra denies, since for the Yogācāra the dependent “really exists as a substance, like the basis of an illusory manifestation.” So gzhan stong is not faithful even to its declared Yogācāra base. The argument cuts two ways: it shows that Dolpopa misreads Maitreya and Asaṅga, and it shows that the correct Yogācāra position retains a residue of true-grasping at the paratantra, which is what makes it Cittamātra rather than Madhyamaka in the first place. See Tathāgatagarbha for the structural counterpoint. (From gorampa-distinguishing-views-1469, section 2.)
Atiśa’s contemplative Madhyamaka emptiness: For Atiśa, all conventional realities are false projections of ignorance, “mere appearances” (snang ba tsam) without any real basis (avastuka). Unlike Śāntarakṣita and Kamalaśīla, who grant conventional reality a real basis in mental elements, Atiśa holds that even the basis of designation and the designating agent are dependent designations lacking substantial existence. Emptiness is not realised through valid cognition (pramāṇa): “The deluded whose vision is narrow say that emptiness is understood by [direct perception and inference]” (SDA v. 10). Rather, analytical reasoning dissolves itself in meditation, like fire consuming the sticks that produced it, leading to nonconceptual gnosis. At buddhahood, all appearances cease, wisdom included: “A Buddha does not have at all [a continuum of wisdom]. He is incomparable.” This was Atiśa’s most controversial position, opposed by his Yogācāra contemporaries and not fully understood by some of his own Tibetan disciples. (From apple-jewels-middle-way-2018.)
Shakya Chokden’s “grand unity” — self-emptiness AND other-emptiness: Shakya Chokden insists on the literal reading of self-emptiness: all phenomena are empty of themselves — a pot empty of the pot. He charges that Tsongkhapa’s version (phenomena empty of a separately identified object of negation, “true establishment”) is structurally identical to other-emptiness, since the basis of negation is empty of something other than itself. Shakya Chokden holds at once that the Niḥsvabhāvavāda self-emptiness reasoning is the most effective tool for severing conceptual proliferations, and that the Alīkākāravāda other-emptiness gives the better identification of what is actually experienced in meditative equipoise — non-dual primordial mind. He never abandoned self-emptiness for other-emptiness, but expanded his view of Madhyamaka to include both, in what amounts to a “polygamous marriage” to the two types of emptiness. His other-emptiness differs from Dolpopa’s: the dependent natures (dualistic consciousness) are the basis of emptiness, empty of the imaginary natures (apprehended and apprehender), and the result is the thoroughly established nature (primordial mind). For Dolpopa, by contrast, the thoroughly established nature itself is the basis, empty of the other two natures. (From komarovski-visions-unity-2011.)
Textual loci
- Early Pāli-canonical loci of suññatā (catalogued in chowdhury-nagarjuna-hermeneutics-2018): Cūḷa-suññata Sutta MN 121 — suññatā as meditative dwelling (suññatā-vihāra); Mahā-suññata Sutta — the world is empty of self or anything pertaining to a self (suññam idaṁ attena vā attaniyena vā); Āneñjasappāya Sutta MN 106 — suññāgāra, an “empty place” as the locus for mindful breathing; Mahāvedalla Sutta MN 43 — suññatā-cetovimutti, “release of mind through emptiness.” This pre-Madhyamaka stratum frames śūnyatā as a meditative-soteriological notion, not yet as the universal anti-substance argument it becomes in the MMK. Karunadasa (karunadasa-theravada-abhidhamma-2010 Introduction p. 8; Ch 1 p. 40) reads the same stratum doctrinally: the world is empty “of self or of anything pertaining to a self” (attena vā attaniyena vā suññaṃ), so that “empty” (suñña) and “non-self” (anattā) are “mutually convertible expressions” — licensing the restatement of sabbe dhammā anattā as sabbe dhammā suññā. On this Theravāda reading suññatā is anchored to anattā and does not, of itself, extend to a universal niḥsvabhāva of all phenomena.
