Chapter 4. Mahāyāna and the schools¶

The first three chapters have examined Mahāyāna's origins, scriptures, and ideal. This chapter draws them together by examining its relationship with the schools that preceded it and continued alongside it. Mahāyāna's own presentation favors an account of rupture and separate origins, disparaging the other side as "Hīnayāna" and claiming to be a higher vehicle. The historical facts in 4.1 favor an account of development within the schools' traditions. Mahāyāna grew within them and shared their disciplinary codes. The present book examines the relationship along several distinct dimensions.

1. Continuity: development from within the schools¶

Consider continuity first.

Institutionally, Mahāyāna remained within the schools. As 4.1 explained, Mahāyāna had no independent ordination lineage and did not split from the saṅgha. Mahāyāna monks received ordination in a school, lived by its Vinaya, and shared monasteries with non-Mahāyāna monks. Institutionally, it was an intellectual movement living off and growing within existing schools, not a nineteenth or twentieth school alongside them.^{1 2}

Mahāyāna drew its strongest doctrinal challenges from older lines of thought. Emptiness pushes not-self, dependent origination, and the middle way beyond existence and nonexistence in the Kātyāyana Discourse (1.5) to their limit, until the intrinsic nature of "dharmas" is also denied. The bodhisattva ideal continues a conception already familiar to the schools. Its layers in the discourse collection must first be distinguished. The most common use of "bodhisattva" appears in an autobiographical formula: "before my awakening, while I was still a bodhisattva." Here it means Gautama before awakening in this very life. Strictly speaking, it denotes an earlier phase, not a previous birth (4.3). The layer of practice across successive lives emerges only through identification with past lives and later literature of predictions. This is the layer inherited by the schools: both Sarvāstivāda and Mahāsāṃghika discussed the Buddha's bodhisattva stage. Mahāyāna generalized this "path to Buddhahood" from the Buddha alone into a path that anyone could vow to follow.

The line of thought that understands the Buddha as transcending historical limits deserves particular detail. Mahāsāṃghika developed a conception called supramundane doctrine (lokottaravāda). The Buddha's body is unstained by worldly contaminants; eating, sleeping, traveling, and similar actions are only illusory appearances manifested in response to beings. The true Buddha always remains in concentration (samādhi), knows everything, and has a form body, powers, and lifespan without limit. The Caitika school of the Andhra region and its Eastern and Western Mountain offshoots were especially ardent supporters of this view.³ There is clear conceptual continuity with the Lotus's "Buddha who abides forever without extinction" and Amitābha's eternal teaching in the Amitābha Sūtra. In 2.3, the present book already identified Mahāsāṃghika as an important part of Mahāyāna's background; supramundane doctrine supplies the most concrete connection.

Mahāyāna was therefore not a new religion founded apart from the schools' traditions. Premises or antecedents for many of its central ideas can be found within them.

2. Mahāyāna is not Mahāsāṃghika: from popular confusion to a named hypothesis¶

The previous section traced Mahāyāna antecedents such as supramundane doctrine to Mahāsāṃghika. Turning this connection into an identity is common in popular accounts and has also been formally proposed in scholarship. Chapter 4.1 registered it as a named hypothesis. In the nineteenth century, Kern, Waddell, and Rhys Davids argued that Mahāyāna sūtras originated in the Mahāsāṃghika branch. The hypothesis was abandoned in the late twentieth century and recently revived by Karashima Seishi through evidence concerning the names Ajita and Maitreya. Mainstream scholarship still rejects it. The collection edited by Harrison and Silk's extended review provide textual responses. The editors of the Kanaganahalli inscriptions and subsequent specialized research address the site's school affiliations through inscriptional evidence. This section does not retrace the philological path of 4.1. It adds two bodies of evidence not used there: one concerning ordination lineages, the other the duration of Mahāsāṃghika's own survival. Each is independent and does not require first settling the school origins of particular scriptures.

The first is a category error at the level of ordination lineage. Earlier discussions (2.3 and 4.1) explained the distinction positively. Mahāyāna was an intellectual movement across schools, living off several disciplinary lineages. Monks inclined toward Mahāyāna could receive Sarvāstivāda, Mahāsāṃghika, or other ordination. Mahāsāṃghika, by contrast, was a school with an independent ordination lineage, the great majority of whose monks did not practice Mahāyāna. One is a movement of thought, the other a disciplinary lineage. They do not belong to the same level and cannot simply be equated. Continuity in ideas does not establish institutional identity.

The second counterargument comes from Mahāsāṃghika's own fate. Mahāsāṃghika as a school and Mahāyāna followed two historical courses that did not coincide. The school persisted as an independent disciplinary lineage until the end of Indian Buddhism; it did not turn into Mahāyāna at some particular point. Its fate is itself often misunderstood. The common impression is that Mahāsāṃghika vanished early, but its disappearance took much longer than usually imagined. In the early fifth century, Faxian still copied the Mahāsāṃghika Vinaya at Pāṭaliputra and brought it back for translation in China. In the seventh century, Xuanzang recorded the prevalence around Bamiyan of the Lokottaravāda branch of Mahāsāṃghika. The Mahāvastu is the only complete Vinaya work of this branch to survive. As late as the end of the seventh century, Yijing still listed Mahāsāṃghika among India's four major schools, with lineages remaining in Magadha and elsewhere. Recently studied Bamiyan manuscripts in the Schøyen Collection also confirm the survival of Lokottaravāda literature into the seventh and eighth centuries.⁴ A particularly striking datum is that Atiśa (982 to 1054) received precisely Mahāsāṃghika ordination.⁵ This means that the lineage survived at least into the eleventh century, nearly as long as Indian Buddhism itself. Its disappearance came with the collapse of Indian Buddhism as a whole, not through doctrinal refutation or defeat by another school within the saṅgha. Only three bhikṣu ordination lineages survive worldwide today: Theravāda, Dharmaguptaka, and Mūlasarvāstivāda.⁶ None continues the Mahāsāṃghika lineage.

The evidence therefore establishes that Mahāsāṃghika did not merge into Mahāyāna. It remained an independent school for more than a thousand years and ultimately perished with Indian Buddhism. Confusing the two misunderstands Mahāyāna's character as a movement across schools and erases Mahāsāṃghika's complete history. Mahāyāna drew on several Mahāsāṃghika ideas, including supramundane doctrine and the original purity of mind, as the present book has repeatedly stated. But drawing on ideas differs from sharing an identity; this section maintains that boundary. Its two bodies of evidence complement the philological discussion in 4.1. There the question concerned the school origins of certain scriptures; here the evidence concerns ordination lineages and survival dates. Different kinds of evidence lead to the same conclusion.

3. Discontinuity: new texts, ideals, and institutions¶

Mahāyāna also introduced new elements; it did more than repeat older teachings.

An entire body of scriptures, including Prajñāpāramitā and the Lotus, was new (4.1 and 4.2). Absent from the schools' early Āgamas, they brought new claims. The emptiness of all dharmas shook the foundations of the intrinsic nature so painstakingly established by Abhidharma. The bodhisattva path became a universal goal, extending beyond the concern of a few, and Buddhas and pure lands acquired a cosmic scope. Also new was the redefinition of the criterion for "the Buddha's word" as "what is well spoken is the Buddha's word" (4.1). Most conspicuous was a previously absent division between self and other, disparaging the other side as "Hīnayāna" and calling oneself "Mahāyāna." This strongly evaluative dichotomy was Mahāyāna's invention. The schools did not divide themselves this way.

The bodhisattva precepts (bodhisattvasīla) were a further institutional innovation. The schools' bhikṣu and bhikṣuṇī precepts rest on the Vinaya collections, with rules, procedures for formal acts, and identifiable historical sources. Bodhisattva precepts constitute a separate Mahāyāna ordination system. At ordination one arouses bodhicitta and makes vows, shifting what one undertakes to uphold from rules formulated by others to one's own promises to beings. In India, Yogācāra's Yogācārabhūmi contains a system of bodhisattva precepts, the three collections of pure precepts: restraining misconduct, cultivating good qualities, and benefiting sentient beings. It is a relatively reliable Indian source. In East Asia, the more influential text is the Brahmā's Net Sūtra, whose ten major and forty-eight minor precepts became an important source for Chinese monastic ordination. Scholars almost unanimously identify it as a Chinese apocryphal composition, much like the Śūraṃgama: no corresponding Sanskrit or Tibetan text survives, and its style closely fits the context of Chinese Buddhism.⁷ East Asian monastics receive both the Vinaya's bhikṣu precepts and the Brahmā's Net bodhisattva precepts. This parallel system is a distinctive product of Chinese Buddhist institutions, absent from India.

Thus, on one side stand shared institutions and many inherited premises; on the other stand new scriptures, goals, criteria, and polemical positions, together with a new ordination system, the bodhisattva precepts. "Rupture or continuity" is itself too broad a question. The answer must distinguish dimensions.

4. Direct challenges within India: the dispute over Mahāyāna as the Buddha's word¶

People in India explicitly and directly said that "Mahāyāna is not the Buddha's word." Popular accounts often skip this historical fact.

This challenge came not from other religions outside Mahāyāna but from colleagues within the same monastic community. During his seventh-century travels west, Xuanzang recorded such disputes. Mahāyāna and non-Mahāyāna monks shared monasteries throughout India, and reservations among the latter about the authority of Mahāyāna scriptures were not unusual. In his Record of Buddhist Practices Sent Home from the Southern Seas, Yijing (635 to 713) gives a cooler observational account than Xuanzang. He explicitly writes that most monastics in the Indian communities he saw, including South and Southeast Asia, defined themselves not as "Mahāyāna" or "non-Mahāyāna," but by their disciplinary school affiliations, such as Sarvāstivāda or Vibhajyavāda. "Mahāyāna" designated an inclination toward particular scriptures and forms of practice, not an independent ordination community.⁸ This precisely matches the account of "Mahāyāna as an intellectual movement across schools" in 4.1.

The challenge left direct traces within Mahāyāna literature. Chapter 2 of the Mahāyānasūtrālaṃkāra, "Establishing the Teaching," opens explicitly: "Some doubt that this Mahāyāna was spoken by the Buddha: how, then, can these virtues be attained? I shall now cut through their net of doubt and establish that Mahāyāna truly is the Buddha's word."⁹ Usually attributed to Maitreya as composer of the verses and Asaṅga as recorder, this treatise is among Yogācāra's central theoretical texts. Making "establishing that Mahāyāna truly is the Buddha's word" the primary task of its second chapter shows that even Mahāyāna's own systematic works recognized its authority as a challenge requiring a direct answer, not a premise that could be passed over. The presence of doubters had become too substantial for mainstream Mahāyāna thinkers to ignore.

Bhāviveka (c. 500 to 570) also records direct challenges to Mahāyāna authority at the philosophical level. He notes that some contemporaries rejected Madhyamaka arguments because "Mahāyāna sūtras are not the Buddha's word," requiring him to address the challenge specifically in philosophical writing.¹⁰ The Mahāyāna responses were listed in 4.1: what is well spoken is the Buddha's word, the dharmakāya always teaches, and teachings are received in meditation. The dispute itself shows that Mahāyāna's status as Buddhism was no self-evident matter in India. It required argument and faced continuing challenges in actual monastic life.

The situation in China differed. When Buddhism entered China, the distinction between "Mahāyāna" and "non-Mahāyāna" did not take the form of shared monasteries and a common Vinaya. Many scriptures arrived together, confronting Chinese monks with a body of texts presented on a relatively level plane. Monks who rejected Mahāyāna did exist. During the Yuanjia era of the Liu Song, Zhu Fadu permitted the reading of only Hīnayāna scriptures, and several monasteries in the capital and nuns in the eastern regions adopted his practice. Earlier, Huidao had doubted the Large Prajñāpāramitā, and Tanle had rejected the Lotus. They were dismissed as misguided students, however, and did not become an equal counterpart to Mahāyāna sharing monasteries and discipline.¹¹ China subsequently organized the internal relations of this body of texts through classifications of teachings rather than institutional divisions. These included Tiantai's five periods and eight teachings, Huayan's five teachings, and consciousness-only thought's three periods.¹² The question "Is this the Buddha's word?" was not absent in China; its subject changed. Cataloguers asked whether a scripture had a demonstrable origin to the west. If it could be shown to have been translated from a foreign original, it was treated as the Buddha's word, whether Mahāyāna or Hīnayāna. The continuing Indian dispute over whether Mahāyāna itself was the Buddha's word remained marginal in China.¹³

5. Distinguishing the dimensions¶

This table gives the book's answer to the old question. Mahāyāna remained institutionally within the schools while making new developments in texts, doctrine, and self-definition, then placing itself above them. Imagining it as "another Buddhism" alongside the schools, or as one of two opposing camps from the start, is largely a later retrospective construction, especially under the influence of Mahāyāna classifications of teachings. In actual monasteries, practitioners inclined toward Mahāyāna and those who were not lived under the same roof for centuries.¹⁴

(For the geography of Mahāyāna's rise and coexistence with the schools, see the map in 4.1.)

6. The "three turnings of the Dharma wheel" and competing classifications: how Mahāyāna places the schools¶

Mahāyāna handles its relationship with older teachings through doctrinal classification, ranking all teachings and assigning each tradition a place. The best-known scheme is the "three turnings of the Dharma wheel," from the Saṃdhinirmocana Sūtra tradition.¹⁵

This ordering expresses Yogācāra's own position. It reduces the teachings of the path to liberation to an initial stage and ranks Prajñāpāramitā's "all is empty" as higher but not ultimate, because it can be misunderstood as "nihilistic emptiness." It finally presents consciousness-only thought's three-nature doctrine as the final answer.

Madhyamaka does not accept this framework. For Madhyamaka, Prajñāpāramitā emptiness is definitive and needs no "third turning" to surpass it. Yogācāra distinguishes the scope of emptiness through the three natures, the imagined, dependent, and perfected. Madhyamaka seeks to refute precisely that distinction. It holds that Yogācāra has thereby established another real existent, the perfected nature, and has failed to carry its analysis through. Their dispute over which teaching is definitive runs throughout late Indian Buddhist philosophy (see Essay 6).

Tiantai classifies teachings differently. Chinese Tiantai does not adopt the three-turning framework. It divides the Buddha's lifetime of teaching into five periods according to the sequence of his instruction: Avataṃsaka, Deer Park (the four Āgamas), Vaipulya, Prajñāpāramitā, and Lotus–Nirvāṇa. It treats the Lotus Sūtra and Mahāparinirvāṇa Sūtra as the highest and ultimate teachings. The Lotus's "one vehicle," which incorporates all vehicles, is the final definitive teaching. For Tiantai, Prajñāpāramitā belongs to the fourth period and still awaits completion by the Lotus. The Vaipulya period includes the Laṅkāvatāra, associated with Yogācāra, but does not classify it as ultimate. This differs completely from the three-turning sequence.¹⁶

The existence of doctrinal classification is itself a clue. There has never been a single answer to how Mahāyāna should place the schools' teachings or rank its own internal traditions. Each lineage devises its arrangement according to its philosophical position. This also confirms the judgment in 4.1: Mahāyāna was not a unified movement. Its internal doctrinal divisions were as deep as those in its relationship with the schools.

Beneath these disputes over rank, however, one point can be established in continuity with the book's earlier argument. Historically, the relationship between Mahāyāna emptiness and the schools' metaphysics developed in response to internal and external pressures. Describing that historical relationship as "correcting a deviation" makes it excessively tidy.

Two levels deserve emphasis. First, the schools' Abhidharma impasse arose precisely from its own metaphysical needs. Once "not-self yet continuity" is accepted, one must answer what continues and how karma and its results continue. Dharmas, intrinsic nature, and real existence in the three times are then established one by one (Essay 3). Once metaphysics begins, it proliferates according to its own logic. Second, the Mūlamadhyamakakārikā responds to this impasse in a distinctive way. It accomplishes its own metaphysics by attacking all metaphysics. It does not establish "what truly exists is X" as a replacement for Sarvāstivāda intrinsic nature, but systematically demonstrates that any claim that "X has intrinsic nature" is inconsistent. The comprehensive rejection of all assertions of intrinsic nature is its standpoint. This is not one metaphysics replacing another, but a position establishing itself by denying all metaphysics. In this respect, Madhyamaka is another response emerging after the schools' metaphysical impasse. It arises because of that impasse, but does not continue the search by adding further bearers.

7. Mahāyāna and the schools: an overall assessment¶

The preceding sections show that Mahāyāna remained institutionally within the schools while introducing new texts and asserting rupture through its rhetoric. In doctrine it both inherited earlier ideas and broke new ground. It inherits not-self, dependent origination, and Mahāsāṃghika lines of thought while rejecting intrinsic nature and advancing the bodhisattva path of universal salvation. It is neither another religion appearing from nowhere nor a simple continuation of older teachings. It is a new form developed within the schools' traditions that then claims superiority over them. Its strand of emptiness is likewise a historical response emerging from the schools' metaphysical impasse, not a simple corrective prescription. The picture of "Mahāyāna against Hīnayāna" as two armies facing off is largely retrospective; the present book does not follow it.

We now turn to the two great undertakings that made Mahāyāna a systematic philosophy. Essay 5 first examines Nāgārjuna's Madhyamaka and how it forges Prajñāpāramitā "emptiness" into a rigorous discipline for dismantling attachment. Essay 6 then examines Yogācāra consciousness-only thought and how it develops another path from "the three realms as mind only."
