Definition
The Two Truths (satyadvaya) doctrine distinguishes between conventional truth (saṃvṛtisatya) and ultimate truth (paramārthasatya). In Madhyamaka, conventional truth is the world of appearances, language, and everyday transactions; ultimate truth is emptiness (śūnyatā) — the absence of intrinsic nature in all phenomena. The two truths are not two separate domains but two ways of understanding the same reality. As Nāgārjuna states in MMK 24:8-10, those who do not understand the distinction between the two truths do not understand the profound truth in the Buddha’s teaching.

| Tsongkhapa | ”Each phenomenon has two natures — an ultimate and a conventional — found by two distinct cognitive processes; not ‘a single nature that is in fact two truths in virtue of the two perspectives’” (Ocean Ch 24 p. 406). At MA 6.23 the same point is articulated as “two natures, identical in nature with distinct conceptual identities” (like produced / impermanent) — these are not in tension: the 1407–08 Ocean and the 1418 Illuminating the Intent formulations are doctrinally continuous, with Ocean the sharper anti-subject-side statement. Ultimate truth is obtained by rational cognition of suchness but “not established through its own essence.” It IS an object of knowledge. The division is exhaustive: no third truth possible. The wiki’s lone explicit “object-side two truths” voice. | Ocean of Reasoning Ch 24; Illuminating the Intent on MA 6.23 | Tsongkhapa |
| Gorampa | Two levels of ultimate truth: quasi-ultimate (rnam grangs pa’i don dam bden pa / don dam pa rjes mthun pa) = the four-extremes-negation reached stepwise by rational analysis, ultimate vis-à-vis a truth-grasping mind but conventional vis-à-vis the equipoise of āryans; real ultimate (don dam mtshan nyid pa) = the simultaneous (cig char du) elimination of all four extremes in non-dual āryan equipoise, where even the appellation “ultimate” is withdrawn. Now primary-grounded at and .1.2. | Distinguishing the Views , .1.2 | Gorampa |
| Dolpopa | Ultimate truth = truly existent thoroughly established nature (tathāgatagarbha, dharmadhātu, self-arisen pristine wisdom); conventional truth = imputational and other-powered natures, empty of own entity. Ultimate truly exists; conventional does not. The two truths are “different… not the same entity… [yet] not different entities” (MD 405) — a categorial separation, not aspects of one reality. Three-natures framework as key. | dolpopa-mountain-doctrine-1333 (Mountain Doctrine 342, 405, now primary) | Dolpopa |
| Tāranātha | Follows Dolpopa; distinguishes “Ordinary Middle Way” (rangtong — ultimate is mere negation) from “Great Middle Way” (zhentong — ultimate truly exists). The Ordinary Middle Way’s error is denying the true existence of ultimate truth. | Essence of Other-Emptiness | Tāranātha |
| Candrakīrti | Conventional things accepted “just as they are known in the world” without ultimate-level analysis; ultimate truth is emptiness understood through dependent origination. | Madhyamakāvatāra, Prasannapadā | |
| Mabja | Two truths depend on “two cognitive perspectives” (twelfth-century Tibetan, pre-polarisation): saṃvṛti is “true as the object of a conventional, deluded mind”; paramārtha is “true as the object of an ultimate mind and rational cognition.” The “vessel for water” image on MMK 24:10: “just as one who wishes for water needs a vessel, it is indeed necessary to teach the relative for there to be a realization of the ultimate.” Pre-Tsongkhapa Tibetan voice on the cognitive-perspective construal — sits structurally between the later object-side (Tsongkhapa) and subject-side (Sakya / Kagyü / Nyingma) readings. | Ornament of Reason Ch 24 commentary on MMK 24:8–10 | Mabja |
| Atiśa (Kadampa) | Ultimate reality is one, undifferentiated, beyond all conceptuality — not realised by valid cognition (pramāṇa). Conventional reality is a false projection of ignorance: “mere appearances” (snang ba tsam) without any real basis. Two types of conventional: mistaken (optical illusions, bad doctrines) and correct (dependent arisings that have causal efficacy when unexamined). Buddhas have no mind or wisdom-continuum — fully fused with dharmadhātu. No pramāṇa for ultimate; reasoning dissolves itself like fire consuming the sticks that produced it. | Satyadvayāvatāra (vv. 1–9); Madhyamakopadeśa; General Explanation | Atiśa |
| Kalupahana | Two truths are NON-hierarchical: saṃvṛti = convention (moral, social, linguistic — not merely language); paramārtha = “ultimate fruit/consequence” (pragmatic, not metaphysical). Neither sublates the other. No indication of “two truths with different standing as higher and lower.” | Philosophy of the Middle Way (1986) | Kalupahana |
| Karunadasa (Theravāda) | Theravāda sammuti-sacca / paramattha-sacca are NON-hierarchical — “two ways of presenting what accords with actuality,” not two degrees of truth; neither sublates the other (both amusā, only true). Etymology load-bearing: Pāli sammuti (“convention,” from man) ≠ Sanskrit saṃvṛti (“concealment,” from vṛ), so the Mahāyāna’s saṃvṛti term “clearly indicates” a hierarchy the Theravāda lacks. The distinction is an Abhidhammic innovation drawn out of the suttas (Aṅguttara nītattha/neyyattha; Saṅgīti Sutta sammuti-ñāṇa/paricchede-ñāṇa). Same etymological move as Kalupahana, from the Abhidhamma side. | The Theravāda Abhidhamma (2010) Ch 3 | Karunadasa |
| Śāntarakṣita / Mipham | Conventional truth analysed through Cittamātra (external objects refuted as mind’s projections); ultimate truth through Madhyamaka (mind itself lacks intrinsic nature). Approximate ultimate (rnam grangs pa’i don dam) = emptiness as conceptually cognised; actual ultimate (rnam grangs ma yin pa’i don dam) = beyond all conceptual elaboration. Both Svātantrika and Prāsaṅgika converge on the actual ultimate. | Madhyamakālaṅkāra (vv. 70–71, 92) | Śāntarakṣita, Mipham |
| Ninth Karmapa (Kagyü) | Two truths are neither the same nor different — beyond all elaborations of sameness or difference. Distinction drawn from the perceiving subject’s side: ultimate truth = what is seen by enlightened beings; relative truth = what is seen by ordinary beings. Even the ultimate truth, when presented as a dichotomous opposite to the relative, is itself a relative truth. Emptiness is a pedagogical tool, not a reified ultimate. Three stages: no analysis (conventions accepted), slight analysis (emptiness), thorough analysis (freedom from elaborations). | Feast for the Fortunate (on MA 6.23) | Ninth Karmapa |
| Dzongsar Khyentse (contemporary Khyentse lineage) | Two truths must be drawn subjectively (from the side of the cognising subject’s defect or wisdom) and never objectively (from the side of the object’s intrinsic existence). All non-Madhyamaka schools commit the object-side error. Four admissible bases for the subjective division (mind, pratītyasamutpāda, sūtra contents, knowledge) are interchangeable. | Madhyamakāvatāra commentary on MA 6.23 (1996–2000 Chanteloube teachings) | Dzongsar Khyentse |
| Siderits (analytic) | Two senses of “ultimate truth”: ultimate truth₁ = a fact that must be grasped to attain enlightenment; ultimate truth₂ = a statement that corresponds to the ultimate nature of mind-independent reality. The doctrine of emptiness says “the ultimate truth₁ is that there is no ultimate truth₂.” Only conventional truth survives, understood as semantic anti-realism (truth as warranted assertibility within useful conventions). Disambiguated satyadvaya device reconstructed in analytic-philosophy idiom; structurally close to Tsongkhapa’s bden grub qualifier but derived independently. | Buddhism as Philosophy Ch 9 (pp. 202–203) | Siderits |
| Garfield (analytic, Prāsaṅgika-Geluk) | The two truths are “Nāgārjuna’s greatest philosophical contribution,” introduced as distinct (24:8) but later identified: there is “no difference in entity” between the conventional and the ultimate; “to see them this way is precisely not to see them as conventional. To see that they are merely conventional… is thereby to see them as empty.” The identity holds because emptiness is empty (24:18). The conventional is not “less true,” and understanding the ultimate “is completely dependent upon understanding conventional truth.” Declares the reading “never conflicts directly with… Candrakīrti.” A modern identity-of-the-two-truths-via-emptiness-of-emptiness reading; lands on the inseparability side, with the Tractatus register flagged as a tension. | The Fundamental Wisdom of the Middle Way Ch XXIV | Garfield |
| Shakya Chokden (Sakya) | Conventional existence = nonexistence; if something exists it must be true (bden). No actual (go chod) ultimate truth was taught in Niḥsvabhāvavāda texts — their emptiness is a “mere metaphorical ultimate” (rnam grangs pa’i don dam). The actual ultimate truth is non-dual primordial mind (ye shes), taught in the third dharmacakra texts. Ultimate reality is an impermanent phenomenon. Two valid types of Madhyamaka ultimate: Niḥsvabhāvavāda’s self-emptiness (view determined by reasoning) and Alīkākāravāda’s other-emptiness (view experienced in meditation) — both lead to the same direct experience. | Profound Thunder, Rain of Ambrosia (via Komarovski 2011) | Shakya Chokden |
Textual loci
- MMK 24:8-10 — the locus classicus; understanding the two truths is necessary for understanding the Buddha’s teaching. Now primary-grounded in Candrakīrti’s Prasannapadā commentary via sprung-lucid-exposition-1979 Translation Ch XVIII (pp. 230–232): Candrakīrti glosses saṃvṛti etymologically as “utterly obscured” by ignorance and as social convention (“the world of ordinary language and of transactions between individuals”); renders MMK 24:10 with the image of ordinary language as “a container for someone who wants water” — the receptacle that carries the water of wisdom
- MMK 24:7 — Candrakīrti’s commentary: “dependent origination” = “emptiness” but “non-existence” ≠ “emptiness.” Now primary-grounded via sprung-lucid-exposition-1979 (p. 234): “śūnyatā has the same meaning as dependent arising; the meaning of non-existence is not the meaning of absence of being”
- MMK 24:18 — pratītyasamutpāda = śūnyatā = prajñaptir upādāya = madhyama pratipad. Now primary-grounded via sprung-lucid-exposition-1979 (p. 238). The translation of prajñaptir upādāya is itself a contested move at this kāriká: Sprung’s Wittgensteinian “non-cognitive guiding notion” rendering vs the Yogācāra-Madhyamaka basis-of-designation reading
- Madhyamakāvatāra 6.23-28 — Candrakīrti’s exposition of the two truths
- Bodhicaryāvatāra 9.2 and 9.106 — Śāntideva’s two-truths exposition, now primary-grounded from the Nyingma side via kunzang-pelden-nectar-manjushri-2007 (ch. 9 following Mipham’s Norbu Ketaka). BCA 9.2 commentary gives two methods of positing the two truths: by examination of ultimate status (appearing mode / abiding mode) and by examination of relative status (whether appearance matches reality for a cognising subject — a subject-side construal). BCA 9.106 commentary supplies the strongest framework-as-pedagogy statement in the wiki’s primary materials: “the system of the two truths is propounded solely for didactic purposes, as an entry to the path. On the ultimate level, the division into two truths has no place.” (object/subject side) and / (Two Truths as method) evidence
- Satyadvayavibhańga (Jñānagarbha) — Indian treatise devoted entirely to the two truths
- Vigrahavyāvartanī v. 28 — Nāgārjuna self-quoting MMK 24:10: “We do not speak without assenting to the conventional truth … Not having had recourse to the conventional, the absolute is not taught. Without having approached the absolute, liberation is not reached.” The self-referential defence of the thesis of universal emptiness against the Naiyāyika dilemma turns on the Two Truths structure. Now primary-grounded via westerhoff-vigrahavyavartani-2010. Direct evidence that the framework is not optional even at the meta-level of defending Madhyamaka against critics. Nāgārjuna explicitly states that all philosophical debate must take place at the conventional level
- Śūnyatāsaptati v. 44 — the most explicit Two Truths hermeneutical statement in Nāgārjuna’s surviving corpus: “Whatever is said by the Buddha has the two truths as its chief underlying thought; it is hard to understand and must be interpreted in this light. When the Buddha says ‘existence’ his chief underlying thought is conventional existence; when he says ‘non-existence’ his chief underlying thought is non-inherent existence.” Direct disambiguation of the Buddha’s “exists” / “does not exist” sayings into conventional existence vs non-inherent existence. Generalises MMK 24:8–10 from a doctrinal claim about the centrality of the Two Truths to a positive interpretive instruction covering the Buddha’s entire teaching. Strongest available Indian primary-text witness for ‘s framework-as-interpretive-necessity claim. Now primary-grounded via komito-seventy-stanzas-1987. Śūnyatāsaptati v. 1 sets the Two Truths register at the outset (the Buddha’s own categorial vocabulary is saṃvṛti-level usage) and v. 70 supplies Nāgārjuna’s own diagnosis of why the nihilist misreading recurs (“Those who do not understand … are frightened by this teaching”)
- Vigrahavyāvartanī v. 70 — close parallel of MMK 24:14: “For whom there is emptiness, there are all things. For whom there is no emptiness there is nothing whatsoever.” Glossed by Nāgārjuna’s own autocommentary as: emptiness = dependent origination = the four noble truths = the path = the three jewels. The Two Truths structure is the precondition of the Buddhist path, not a threat to it
- Āryadeva’s Catuḥśataka — the Two Truths as architecture, not just doctrine. The Four Hundred Verses is organised in two halves: chapters I–VIII on conventional truth and the path (the means), IX–XVI on ultimate truth and the analysis of emptiness, with chapter VIII the explicit pedagogical hinge (the conventional must be correctly understood before the ultimate can be taught). The framework is thus built into the organisation of a treatise by Nāgārjuna’s immediate disciple — direct evidence it is not a later commentarial imposition (, ). Candrakīrti’s Catuḥśatakaṭīkā nonetheless criticises Dharmapāla for treating the two halves as “two distinct parts,” insisting the two truths are interconnected — so the structure witnesses the inseparability of the truths, framework-as-pedagogy rather than a two-level filing system. Primary-grounded via aryadeva-four-hundred-sonam-2008
Interpretations
Gorampa’s two-level ultimate truth (now primary-grounded at Gorampa and .1.2): Gorampa distinguishes between (a) the quasi-ultimate (rnam grangs pa’i don dam bden pa / don dam pa rjes mthun pa), which is the freedom-from-the-four-extremes that is the direct object of stepwise rational analysis but which is, “compared to the stainless equipoise of āryans, only a conventional truth”; and (b) the real ultimate (don dam mtshan nyid pa), reached only when the four extremes are eliminated simultaneously (cig char du), the realised reality and the realising mind do not appear as two, and the appellation “ultimate truth” is itself withdrawn — “at that time, there is no apprehension whatsoever of the fact, this is the ultimate truth.” This means that even the emptiness cognised through philosophical reasoning is not yet the real ultimate truth — it is its rjes mthun, “analogue.” This directly challenges Tsongkhapa’s position that emptiness as a non-affirming negation is the proper object of inferential cognition and the genuine ultimate. Translator’s note 386 records that the rnam grangs pa / mtshan nyid pa terminology has its origin in Indian Svātantrika texts (Jñānagarbha) — Gorampa repurposes Svātantrika terminology for a Prāsaṅgika reading. (From gorampa-distinguishing-views-1469)
Tsongkhapa’s position (in his own words, MMK-anchored): tsongkhapa-ocean-of-reasoning-1408 Ch 24 (p. 406) supplies Tsongkhapa’s most explicit object-side primary statement: “Each of the internal and external phenomena has two natures: an ultimate and a conventional nature. The sprout, for instance, has a nature that is found by a rational cognitive process … and a nature that is found by a conventional cognitive process. The former nature is the ultimate truth of the sprout; the latter nature is the conventional truth of the sprout. … But this does not show that a single nature is in fact two truths in virtue of the two perspectives of the former and latter cognitive processes.” Same Ch 24 develops the etymologies (saṃvṛti read three ways: concealment by ignorance, mutual dependence, signifier-nominal-convention; paramārtha as “fact-and-supremeness” rather than as the object of the wisdom of equipoise, against Bhāviveka). Cf. the parallel articulation at MA 6.23 in Illuminating the Intent: “two natures — conventional and ultimate — identical in nature but with distinct conceptual identities” (like “being produced” and “being impermanent”). The 1407–08 Ocean statement is the sharper anti-subject-side formulation; the 1418 MA-anchored statement is the more reconciliatory formulation. Crucially, ultimate truth IS an object of knowledge; ultimate is “not established through its own essence” (the pre-emption of the “grasping at emptiness” objection). Within conventional, veridical (unimpaired senses) vs distorted (impaired senses) is drawn only from the worldly perspective, not the ārya perspective. (From tsongkhapa-ocean-of-reasoning-1408 Ch 24 and tsongkhapa-illuminating-intent-1418 Ch 11)
Tsongkhapa’s bivalence defence — “no third truth”: Tsongkhapa explicitly defends the exhaustiveness of the two-truths division at MA 6.23 against critics (later including Mipham and the Ninth Karmapa) who treat the division as a pedagogical convention beyond which a third option lies. He argues by direct opposition: “deceptive” and “nondeceptive” are mutually exclusive predicates that admit no third term, citing Kamalaśīla’s Madhyamakāloka on direct opposites — once one is eliminated, the other is established by exclusion. He extends this to defend bivalent reasoning generally within Prāsaṅgika (“whether something does or does not exist,” “whether it is one or many”) against those who claim Prāsaṅgika rejects all direct opposites. The Meditation on the Definite Revelation of Suchness is cited verbatim: “There is the conventional and likewise the ultimate; there is never such a thing as a third truth.” (From tsongkhapa-illuminating-intent-1418, Ch 11)
Tsongkhapa’s three criteria for conventional existence: Conventional cognition (tha snyad pa’i shes pa) — what Candrakīrti calls “unexamined cognition” (ma dpyad pa’i shes pa) — is the kind of cognition that engages its objects within the context of how they appear, without analysing whether the appearance corresponds to actual mode of existence. It occurs in everyone whether or not their minds have been exposed to philosophical systems. To be conventionally existent, on Tsongkhapa’s account, a fact must satisfy three criteria: (1) it is acknowledged within conventional cognition; (2) it is not invalidated by another conventional valid cognition; (3) it is not invalidated by analysis probing the ultimate nature of reality. This is Tsongkhapa’s positive content for “deferring to the world” — not abdication to cowherds but appeal to the unanalysed perspective shared by reflective philosophers and ordinary persons alike. The three criteria are the primary-text basis for distinguishing his “robust conventional existence” from the rope-snake (which fails criterion 2) and from intrinsic existence (which fails criterion 3). (From tsongkhapa-illuminating-intent-1418, Ch 11, on MA 6.25–28)
Tsongkhapa on the buddha’s single gnosis with two modes (Ch 25): The two-truths division as defined at MA 6.23 holds in general but admits a special case at buddhahood. Tsongkhapa argues — against the position that a buddha’s gnosis perceives only emptiness and that conventional perception is reserved for trainees — that a buddha possesses a single gnosis with two distinct modes of knowing defined by its two distinct objects (the way things really are, ji lta ba; and things in their diversity, ji snyed pa). At buddhahood the alternation between equipoise and post-equipoise ceases; the buddha continuously abides in equipoise on emptiness and yet perceives all of conventional reality without dualistic delusion. The cost of denying this, Tsongkhapa argues, is that the buddha would no longer be omniscient — the ten powers, defined in terms of knowledge of specific facts, would become incoherent. He concedes this is “a formidable but crucial challenge for Madhyamaka” rather than a free-standing claim, and explicitly rebukes “those who say that in this system there is no nonconceptual gnosis realising the ultimate truth” as denigrating the supreme realisation of the āryas. (From tsongkhapa-illuminating-intent-1418, Ch 25, on MA 11.10–17)
Gorampa’s critique of Tsongkhapa: Gorampa charges that this grasps at emptiness as a conceptual object, failing to transcend proliferation. The real ultimate is ineffable and beyond inferential cognition. (From gorampa-distinguishing-views-1469)
Gorampa’s verse-level reductio of Tsongkhapa on MA 6.23 (now primary-grounded at gorampa-removal-wrong-views pp. 173–175 [Tib. 113–115]): Beyond the thematic charge of “grasping at emptiness,” Gorampa attacks Tsongkhapa’s “single nature with distinct conceptual identities” reading directly at MA 6.23 in five steps: (1) the single-nature thesis entails that “the nature found by a delusive perception is the nature found by an authentic perception”; (2) it entails that the cognitive procedures of the two truths are indistinguishable; (3) it entails that the meditative balance of the holy perceives the very basis found by delusive perception; (4) it makes the bden grub qualifier necessary — Gorampa derives Tsongkhapa’s central methodological move as a cost of the underlying error rather than as its solution; (5) Nāgārjuna’s Bodhicittavivaraṇa “produced/impermanent” analogy that Tsongkhapa cites in fact epitomises the non-existence of separate natures, not the existence of a single nature — the Centrist Consequentialist accepts neither. Re-anchored at MA 6.29 [Tib. 125, p. 188]: “This text [MA] also negates that the two truths are a single nature” — Candrakīrti’s own hairs/bell-metal image at MA VI.29 cited as primary witness against Tsongkhapa. This is the wiki’s strongest verse-level case for the paper claim that Tibetan disagreements are sophisticated and within the shared hermeneutical framework.
Dolpopa’s inversion (via Gorampa’s critique): Dolpopa identifies ultimate truth with truly existent Buddha-nature, reversing the standard Madhyamaka understanding. Gorampa classifies this as eternalism. (From gorampa-distinguishing-views-1469)
Zhentong Two Truths (via sympathetic Jonang account): In Tāranātha’s presentation, the conventional includes all imputational and other-powered natures — the entirety of apprehended-object and apprehending-subject. The ultimate is the thoroughly established nature: self-arisen pristine wisdom, tathāgatagarbha, dharmadhātu. The critical move is that the ultimate truly exists — it withstands analysis by the reasoning of dependent-arising and the lack of being one or many. Dolpopa’s Mountain Doctrine argues that if something is not ultimately true, it is not suitable as an ultimate truth — and therefore ultimate truth is ultimately true and conventionally untrue, while conventional truth is conventionally true and ultimately untrue. This is a strict asymmetry, unlike the rangtong positions where the two truths are aspects of the same reality. The “Ordinary Middle Way” errs by extending the negation of true existence even to the ultimate, leaving nothing truly established — which Dolpopa regards as falling into the extreme of non-existence. (Now primary-grounded at dolpopa-mountain-doctrine-1333 342, 405; “existing in the dispositional mode of subsistence” is what ultimately existing means, MD 225; concise synthesis at taranatha-essence-other-emptiness-2007, pp. 57–58.)
