Chapter 4 Mahāyāna and the Early Schools¶

The preceding chapters have clarified the origins, scriptures, and ideal of Mahāyāna. This chapter draws them together by asking what relationship Mahāyāna had with the schools that preceded and coexisted with it. Was it a rupture that started over, or a new form developed within the traditions of the schools? Mahāyāna's own rhetoric favors the former: it disparages opponents as an "inferior vehicle" and claims to be a higher vehicle. The historical evidence in 4.1 favors the latter: Mahāyāna grew within the schools and shared their Vinayas. This book separates the relationship into several dimensions.

1. Continuity: Development from within the Schools¶

We begin with continuity.

Institutionally, Mahāyāna remained within the schools. As 4.1 explained, Mahāyāna had no independent ordination lineage and did not split from the Saṅgha. A Mahāyāna monk was ordained according to the rules of a particular school, lived under its Vinaya, and shared a monastery with non-Mahāyāna monks. Institutionally, Mahāyāna was a current that attached itself to and grew within the existing schools, not a nineteenth or twentieth school beside them.²³

Doctrinally, Mahāyāna drew its most forceful moves from existing threads. Emptiness pushes not-self, dependent arising, and the middle way between existence and nonexistence in the Kaccānagotta Sutta (1.5) to their conclusion, denying intrinsic nature even to "dharmas." The bodhisattva ideal continues an idea already familiar to the schools. The Buddha's practices over his former lives before awakening were called bodhisattva practice. Both Sarvāstivādins and Mahāsāṃghikas discussed the Buddha's bodhisattva stage. Mahāyāna generalized this "path to buddhahood" from one person into a route that anyone could vow to follow.

The line that understood the Buddha as transcending historical limitations especially deserves detail. The Mahāsāṃghikas developed a view called Lokottaravāda, the "supramundane doctrine." The Buddha's body was uncontaminated by worldly taints; eating, sleeping, traveling, and other activities were only illusory appearances manifested for beings. The true Buddha always remained in meditative equipoise (samādhi), knew all things, and transcended temporal limitations. The Caitikas, a Mahāsāṃghika branch, pushed the line further, maintaining that the Buddha's life in the Sahā world was itself only an expedient display, while in reality he taught eternally in a higher buddha land.⁵ This shows clear conceptual continuity with the eternal, non-abiding Buddha of the Lotus and Amitābha's enduring teaching in the Amitābha Sūtra. Chapter 4.3 already identified the Mahāsāṃghikas as an important background to Mahāyāna; the Lokottaravāda supplies the most concrete thread.

Mahāyāna was therefore not a new religion created outside the early schools. Premises or traces of many central Mahāyāna ideas can be found within them.

2. A Misunderstanding That Must Be Corrected: Mahāyāna Is Not the Mahāsāṃghika School¶

The previous section traced Mahāyāna ideas such as a supramundane Buddha to the Mahāsāṃghikas. Popular accounts consequently often identify Mahāyāna directly with the Mahāsāṃghika school, treating the school as Mahāyāna's predecessor or Mahāyāna as its continuation. The equation fails in both directions and requires explicit correction.

First is a category mistake. As 2.3 and 4.1 explained positively, Mahāyāna was an intellectual current across the schools, attached to multiple Vinaya lineages. A monk sympathetic to Mahāyāna might be ordained under the Sarvāstivāda, Mahāsāṃghika, or another Vinaya. The Mahāsāṃghika, by contrast, was a school with an independent ordination lineage, and the great majority of its monks did not practice Mahāyāna. One was an intellectual movement and the other a Vinaya lineage; they existed on different levels and cannot be identical. Inheriting ideas does not entail institutional identity.

Stronger counterevidence comes from the fate of the Mahāsāṃghikas themselves. The school and Mahāyāna followed two historical trajectories that never fully overlapped. The Mahāsāṃghikas remained an independent Vinaya lineage until the end of Indian Buddhism; they did not transform into Mahāyāna at some point. Their longevity is itself often misunderstood. The common impression is that they disappeared early, but the process was far longer. In the early fifth century Faxian obtained a copy of the Mahāsāṃghika Vinaya at Pāṭaliputra, brought it to China, and translated it. In the seventh century Xuanzang recorded the prevalence of the Lokottaravāda branch around Bamiyan; the Mahāvastu is the only complete Vinaya-related work to survive from this line. At the end of the seventh century Yijing still counted the Mahāsāṃghikas among the four great schools of India, with lineages in Magadha and elsewhere. Recently recovered Bamiyan manuscripts in the Schøyen Collection confirm that Lokottaravāda literature survived into the seventh and eighth centuries.⁶ The most remarkable datum is that Atiśa (982–1054) himself received Mahāsāṃghika ordination.⁷ The lineage therefore survived at least into the eleventh century, almost as long as Indian Buddhism. It vanished not through doctrinal refutation or defeat by another school, but with Indian Buddhism as a whole. Only three full-ordination lineages survive globally today—the Theravāda, Dharmaguptaka, and Mūlasarvāstivāda⁸—and no Mahāsāṃghika Vinaya lineage remains.

The conclusion is firm. The Mahāsāṃghikas did not merge into Mahāyāna; they continued independently for more than a millennium and ultimately disappeared with Indian Buddhism. Confusing them with Mahāyāna misconstrues Mahāyāna's cross-school character and erases the Mahāsāṃghikas' own complete history. Mahāyāna adopted several intellectual threads from them—Lokottaravāda and the intrinsic purity of mind, repeatedly noted in this book—but borrowing a thread is not identity. That is the boundary this section preserves.

3. Discontinuity: New Texts, Ideals, and Institutions¶

Continuity does not mean that Mahāyāna merely repeated old teachings. Several features were genuinely new.

A large body of new scriptures appeared: Prajñāpāramitā, the Lotus, and others discussed in 4.1 and 4.2. They were absent from the early Āgamas and carried new claims: all dharmas are empty, undermining at its foundation the intrinsic nature painstakingly constructed by Abhidharma; the bodhisattva path is the universal destination rather than the concern of a small number of people; buddhas and pure lands are cosmic. Mahāyāna also redefined the criterion for "the Buddha's word" (4.1): "what is well spoken is the Buddha's word." Most conspicuously, it created a new division of self and other: it disparaged opponents as an "inferior vehicle" and called itself the "great vehicle." The schools themselves had never divided Buddhism this way. The strongly evaluative binary was a Mahāyāna invention.

One institutional creation was genuinely new: the bodhisattva precepts (bodhisattvasīla). The monastic rules of the different schools rested on Vinaya collections with rules, formal procedures, and traceable historical origins. Mahāyāna established a separate form of ordination centered on taking the aspiration to awakening and shifting the object of discipline from rules established by others toward one's promise to beings. In India, the Yogācāra Yogācārabhūmi contains a relatively reliable system of bodhisattva precepts: the three collections of pure precepts—restraint, gathering wholesome dharmas, and benefiting sentient beings. In East Asia, the more influential source was the Brahmā's Net Sūtra. Its ten major and forty-eight minor precepts became important to Chinese monastic ordination. Scholars, however, almost unanimously regard the scripture as a Chinese apocryphon, similar to the Śūraṅgama: it has no corresponding Sanskrit manuscript or Tibetan translation, and its style closely matches the Chinese Buddhist setting.⁹ East Asian monastics receive both Vinaya-based monastic precepts and bodhisattva precepts from the Brahmā's Net, two parallel tracks that form a distinct product of Chinese Buddhist institutions and did not exist in India.

At one end, then, stand shared institutions and numerous inherited premises. At the other are new scriptures, goals, criteria, polemical attitudes, and an additional ordination system. The general question "rupture or continuation?" is too coarse; the answer must be given dimension by dimension.

4. Direct Doubts within India: The Dispute over Whether Mahāyāna Is the Buddha's Word¶

Popular accounts often omit a historical fact: in India some Buddhists stated openly and directly that "Mahāyāna is not the Buddha's word."

The doubts did not come from other religions outside Buddhism but from colleagues within the same Saṅgha. Xuanzang recorded such controversies during his seventh-century journey. In monasteries throughout India, Mahāyāna and non-Mahāyāna monks lived together, and the latter commonly reserved judgment about the authority of Mahāyāna scriptures. Yijing (635–713) offers an even more dispassionate report in his Record of Buddhist Practices Sent Home from the Southern Sea. He states explicitly that in the Indian, South Asian, and Southeast Asian communities he observed, most monastics did not define themselves as "Mahāyāna" or "non-Mahāyāna" but by the school of their Vinaya ordination, such as Sarvāstivāda or Vibhajyavāda. "Mahāyāna" meant an inclination toward particular scriptures and forms of practice, not an independent ordination group.¹⁰ This exactly agrees with 4.1's account of Mahāyāna as a cross-school current.

The doubts left direct traces within Mahāyāna literature. The opening of chapter 2 of the Mahāyānasūtrālaṃkāra, "Establishing the Teaching," states: "Some doubt that this Mahāyāna was spoken by the Buddha. How then can its qualities be obtained? I shall now resolve their web of doubt and establish that Mahāyāna truly is the Buddha's word."¹¹ The verses are traditionally attributed to Maitreya and recorded by Asaṅga, and the work is among the central theoretical texts of Yogācāra. That it made "establishing that Mahāyāna truly is the Buddha's word" the leading task of its second chapter shows that even within Mahāyāna's own systematic writings, the problem of authority was treated as a challenge requiring a direct answer, not a premise that could be ignored. The critics were prominent enough that leading Mahāyāna theorists could not disregard them.

Bhāviveka, around 500–570, also records the philosophical form of the challenge. Some contemporaries rejected Madhyamaka arguments on the ground that Mahāyāna scriptures were not the Buddha's word, forcing him to address the objection within philosophical works.¹² Chapter 4.1 listed the Mahāyāna responses—what is well spoken is the Buddha's word, the Dharma body continually teaches, and scripture may be received in meditative revelation. The point here is simply that the debate itself shows that "is Mahāyāna Buddhism?" was not self-evident in India. It was a position requiring argument and remained contested in actual monastic environments.

The situation in China differed. When Buddhism reached China, the distinction between Mahāyāna and non-Mahāyāna did not present itself as two groups living in the same monastery under the same Vinaya. Large bodies of scripture arrived alongside one another, and Chinese monks encountered a relatively flat textual library without living "non-Mahāyāna monks" under the same roof as a comparison. Chinese traditions later organized the internal relationships of this library through classifications of teachings—Tiantai's five periods and eight teachings, Huayan's five teachings, and Yogācāra's three periods—rather than institutional division. Chinese Buddhism consequently accepted Mahāyāna authority more readily than did its actual Indian environment and engaged less often in substantive self-questioning over whether those texts were the Buddha's word.¹³

5. Distinguishing the Dimensions¶

This table gives the book's answer to the old question. Mahāyāna remained institutionally within the schools, yet developed in new directions in scripture, doctrine, and self-positioning and then placed itself above them. Imagining it as "another kind of Buddhism" standing beside the schools, or projecting two opposing camps back to the beginning, is largely a later construction, especially one influenced by Mahāyāna classifications. For centuries in actual monasteries, practitioners inclined and not inclined toward Mahāyāna lived under the same roof.⁴

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

6. The "Three Turnings" and Competing Classifications: How Mahāyāna Located the Earlier Teachings¶

How did Mahāyāna itself handle its relationship with earlier teachings? It classified the teachings, ranking all doctrines and assigning each a place. The best-known arrangement is the "three turnings of the Dharma wheel" associated with the Saṃdhinirmocana Sūtra:¹

This ordering expresses the self-positioning of Yogācāra. It lowers the liberation-path teachings to a preliminary stage, classifies the Prajñāpāramitā doctrine that "everything is empty" as higher but not final because it can be misunderstood as annihilationist, and treats the three-nature theory of consciousness-only as the final answer.

Madhyamaka does not accept this framework. For Madhyamaka, Prajñāpāramitā emptiness is definitive and needs no third turning to supersede it. The Yogācāra distinction among the imagined, dependent, and perfected natures is precisely what Madhyamaka criticizes. Madhyamaka regards it as establishing a new real entity—the perfected nature—and therefore as insufficiently thorough. The two schools' dispute over which is definitive runs through later Indian Buddhist philosophy; see Part VI.

Tiantai offers another arrangement. The Chinese Tiantai tradition, founded by Zhiyi (538–597), rejects the three-turning structure and teaches "five periods and eight teachings." It divides the Buddha's lifetime of teaching chronologically into the Avataṃsaka, Āgama, Vaipulya, Prajñāpāramitā, and Lotus–Nirvāṇa periods, treating the Lotus Sūtra and Mahāparinirvāṇa Sūtra as most ultimate. The Lotus's "one vehicle" gathers the other vehicles and alone constitutes the final definitive teaching. In Tiantai, Prajñāpāramitā belongs to the fourth period and still awaits completion by the Lotus, while the Saṃdhinirmocana line of Yogācāra is assigned somewhere within the Vaipulya or Prajñāpāramitā period and is not ultimate. This differs entirely from the three turnings.¹⁴

The existence of these classifications is itself evidence. There was never a unified answer to how Mahāyāna should place the schools or rank traditions within Mahāyāna; each line devised an arrangement according to its own philosophy. This confirms the conclusion of 4.1: Mahāyāna was not a unified movement. Its internal doctrinal differences are as deep as its differences with the early schools.

Once the hierarchy of classification is removed, one conclusion can be affirmed that agrees with the line of argument in this book. Historically, the relationship between Mahāyāna "emptiness" and the metaphysics of the schools was a path formed under internal and external pressures. To describe it simply as a "correction" makes the historical relation too neat.

Two layers should be distinguished. First, the difficulty of Abhidharma arose precisely from its own metaphysical demands. Once it accepted "continuity without a self," it had to explain what continues and how karmic results flow. Dharmas, intrinsic nature, and the existence of the three times were successively established; once metaphysics began, it proliferated according to its own logic (Part III). Second, the Mūlamadhyamakakārikā responds to the difficulty in an unusual way: it completes its own metaphysical project by attacking every metaphysics. It does not establish "X is what truly exists" in place of Sarvāstivāda intrinsic nature, but systematically demonstrates that no claim that "X possesses intrinsic nature" is coherent. Its position consists in the universal negation of assertions of intrinsic nature. In this sense Madhyamaka is another response emerging after the difficulty of Abhidharma metaphysics. It arose because of that difficulty but did not continue in the direction of adding still more carriers.

7. Mahāyāna and the Schools: General Assessment¶

To summarize: Mahāyāna was institutionally contained within the schools; in its texts and rhetoric it was new and discontinuous; in doctrine it both inherited—continuing not-self, dependent arising, and Mahāsāṃghika themes—and broke through, rejecting intrinsic nature and universalizing the bodhisattva path. It was neither a different religion appearing from nowhere nor a simple continuation of old teachings. It was a new form that developed within the traditions of the schools and then claimed superiority over them. Its path of emptiness offered a historical answer generated by the difficulty of the schools' metaphysics, not a simple corrective prescription. The image of two armies, "Mahāyāna against Hīnayāna," is largely a retrospective construction and is not used in this book.

The next step is to examine the two great projects that turned Mahāyāna into systematic philosophy. Part V begins with Nāgārjuna's Madhyamaka and asks how it forged Prajñāpāramitā "emptiness" into a rigorous discipline of dismantling attachment. Part VI then turns to Yogācāra consciousness-only and the alternative path it developed from the claim that "the three realms are mind-only."
