Chapter 3. The relations between tathāgatagarbha, consciousness-only, and Madhyamaka¶

The previous two chapters set out the scriptural foundations of tathāgatagarbha (7.1) and its most systematic treatise (7.2). The present chapter addresses the more complex question of its relationship to the contemporary Madhyamaka and consciousness-only traditions. The question is whether they have substantive philosophical differences or merely express the same thing in different ways. It also concerns how their respective thinkers approached the relationship through rejection, absorption, or attempted synthesis.

The relationship already involved clear tensions within Indian Buddhism. After these teachings entered China, translation and interpretation recast the question in distinctive ways, eventually producing syntheses absent from the Indian texts.

1. The origins of the problem: three discourses in uneasy coexistence¶

Placing the core claims of the discourses alongside one another makes their tensions clearer:

All three discourses operate within Mahāyāna and claim compatibility with emptiness, yet their accounts of liberation differ markedly in structure. Madhyamaka describes liberation as cognitive, involving thorough insight into truth and the cessation of conceptual proliferation. Consciousness-only describes a transformation that reverses the character of consciousness. Tathāgatagarbha thought describes a disclosure, removing obscurations to reveal what was already there. The differences are more than rhetorical. They presuppose different metaphysical accounts of what sentient beings in saṃsāra actually are.

2. Tathāgatagarbha and Madhyamaka: two ways of conducting the dialogue¶

Madhyamaka's misgivings about tathāgatagarbha

Madhyamaka, especially Candrakīrti's Prāsaṅgika Madhyamaka, poses the sharpest philosophical challenge to tathāgatagarbha. Candrakīrti's Prāsaṅgika requires that no dharma, including consciousness, serve as a real foundation for anything, even on the strength of "dependently arisen existence" (Chapter 5 of Essay 6). Tathāgatagarbha thought claims that tathāgatagarbha is originally pure and is the source of the Buddha's qualities. Within the Prāsaṅgika framework, this already supplies something with a positive foundation in reality, even if that thing is said to be empty.

Gelug Prāsaṅgika Madhyamaka handles the problem by incorporating the entire discourse of tathāgatagarbha into emptiness. Tathāgatagarbha is simply a positive way of speaking about emptiness, with no independent content beyond it. To say that sentient beings inherently possess tathāgatagarbha is equivalent to saying that their minds have always lacked intrinsic nature and are empty. Practice consists in thoroughly seeing this emptiness. On this reading, tathāgatagarbha is a poetic expression of emptiness, not an independent metaphysical claim.¹

Does this approach succeed?

If tathāgatagarbha is merely another name for emptiness, the meaning of "nonempty tathāgatagarbha," the qualities of Buddha-nature, becomes a problem. Emptiness is negative, while "nonempty tathāgatagarbha" is affirmative. The latter claims that tathāgatagarbha inherently possesses the Buddha's qualities, a claim with no basis in a strictly Prāsaṅgika position. Incorporating nonempty tathāgatagarbha into emptiness as well makes the Buddha's qualities conventionally designated and without intrinsic nature. Yet the claim that tathāgatagarbha inherently possesses those qualities then becomes difficult to understand. Can something conventionally designated "inherently possess" something else that is also conventionally designated?

Nāgārjuna and tathāgatagarbha: a group of disputed texts

A group of works traditionally attributed to Nāgārjuna, including the Dharmadhātustava (Praise of the Dharmadhātu), has a distinctly tathāgatagarbha character. These texts praise the all-pervading purity of the dharmadhātu, suchness, and tathāgatagarbha, in a style quite different from the Mūlamadhyamakakārikā's use of reductio arguments to dismantle attachments.

Modern scholarship is divided. Some scholars regard the texts as possibly pseudonymous works or as representing another aspect of Nāgārjuna's thought. Others hold that Nāgārjuna did offer affirmative accounts of tathāgatagarbha under the names of dharmadhātu and suchness outside the Mūlamadhyamakakārikā.² Whatever their authorship, the texts show that Madhyamaka and tathāgatagarbha discourses in India were not wholly mutually exclusive. They also influenced one another and coexisted to a considerable degree.

The approach of Candrakīrti's tradition

In his commentaries, Candrakīrti explicitly rejects the consciousness-only position that consciousness has positive reality at some level. Likewise, he keeps his distance from tathāgatagarbha's claim to be "nonempty." Within his framework, any assertion of positive reality, even "original purity," becomes another attachment to intrinsic nature. Candrakīrti does not discuss tathāgatagarbha specifically, but the logic of his position excludes every positive claim in tathāgatagarbha discourse that goes beyond emptiness.

3. Tathāgatagarbha and consciousness-only: the equation in the Laṅkāvatāra Sūtra¶

The Laṅkāvatāra Sūtra's strategy

As noted in Chapter 7.1, the Laṅkāvatāra Sūtra explicitly equates tathāgatagarbha with storehouse consciousness. The equation involves a clever strategy. Incorporating tathāgatagarbha into the consciousness-only system gives it a relatively mature philosophical vocabulary for describing how it operates.

The storehouse consciousness is already a concept with an elaborate theory behind it. It is the repository of seeds, the bearer of karmic maturation, and the basis of the stream of consciousness. To equate tathāgatagarbha with the storehouse consciousness is to say that the underlying consciousness, originally pure and bearing the qualities of Buddha-nature, is precisely the storehouse consciousness. Viewed from its contaminated aspect, it is a repository of seeds of the afflictions; viewed from its uncontaminated aspect, it is tathāgatagarbha, the basis for the manifestation of pure nature.

The internal difficulty of this equation

Yet the equation creates a serious philosophical problem. Within the consciousness-only system, storehouse consciousness is a neutral concept with a somewhat negative character. It is the foundation of saṃsāra and carries contaminated seeds. Manas grasps it as "I," and it forms the deepest level of the mechanism of afflictions. Tathāgatagarbha, by contrast, is a positive concept. It is originally pure, the seat of Buddha-nature, and the basis of liberation. The two are almost opposite in their functional orientation.

The Laṅkāvatāra Sūtra acknowledges the tension by giving storehouse consciousness (tathāgatagarbha) two aspects. Its contaminated aspect is the basis of saṃsāra, and its pure aspect is tathāgatagarbha, the foundation of Buddha-nature. The difficulty is how both can coexist in a single consciousness. Their coexistence brings back the tathāgatagarbha tradition's question of how defilement is possible in what is originally pure. Consciousness-only terminology has merely reformulated the problem. The sūtra itself already states the cost of this tension. Under defilement, direct realization is not possible, so ordinary deluded people and non-Buddhists take tathāgatagarbha for a creator or a self. The text anticipates the very point that later "Critical Buddhism" would persistently pursue.³

Immaculate consciousness (amala-vijñāna): Paramārtha's ninth consciousness

As mentioned in Chapter 6.1, Paramārtha (499 to 569) set apart the pure aspect of storehouse consciousness when translating consciousness-only texts. He established it as "immaculate consciousness" (amala-vijñāna), a ninth consciousness corresponding to tathāgatagarbha. No direct source for this move can be found in Indian consciousness-only literature. It was Paramārtha's creative interpretation of the fusion of tathāgatagarbha and consciousness-only thought.⁴

Paramārtha's structure:

Top: immaculate consciousness (ninth) = tathāgatagarbha = pure intrinsic nature. Middle: storehouse consciousness (eighth), the defiled basis of consciousness, carrying seeds of the afflictions. Bottom: the first seven, active consciousnesses—producing karma, perfuming, and continued transmigration. Right: transformation of the basis complete; tathāgatagarbha realized. The arrows run from top to middle to bottom. The separate arrow from the top to the right is labelled “fully revealed at liberation.”

The structure attempts to resolve the tension between the contaminated character of storehouse consciousness and the purity of tathāgatagarbha. It sets apart the pure aspect as a ninth consciousness and leaves storehouse consciousness to perform only contaminated functions. Tathāgatagarbha (immaculate consciousness) is fully revealed only at liberation.

The problem with this proposal is that establishing a separate "pure consciousness" as an underlying level within the consciousness-only system still gives something a positive foundation in reality. Madhyamaka's criticism of consciousness as conceived by the consciousness-only school, especially Candrakīrti's, applies equally to this ninth consciousness. Paramārtha's creative interpretation found no continuing lineage in India itself, but had a profound influence in China. It became an important precursor to the framework of the Awakening of Mahāyāna Faith.

4. The Awakening of Mahāyāna Faith: a Chinese synthesis¶

The Awakening of Mahāyāna Faith (Mahāyāna-śraddhotpāda-śāstra) is one of the most influential "treatises" in all of Chinese Buddhism, and a key text for understanding how the fusion of tathāgatagarbha and consciousness-only evolved in China.

The question of authorship

Chinese Buddhist tradition attributes the work to Aśvaghoṣa, who lived approximately in the first to second centuries. Modern scholarship almost unanimously regards it as a Chinese composition dating to approximately the sixth century, possibly produced within Paramārtha's circle or under his direct influence. Several reasons support this view. No Sanskrit text survives today. An old account says that the Sanskrit text used by Śikṣānanda was a back-translation from Chinese made by Xuanzang at the request of Indian monks, as recorded in Daoxuan's Continued Biographies of Eminent Monks. The account is itself questionable and in any case cannot establish an independent Indian source. The text's conceptual structure and terminology do not match Indian literature. They correspond precisely to the discussion of a tathāgatagarbha and consciousness-only synthesis that emerged in China after Paramārtha's translations.⁵

The position of this book is that the Awakening of Mahāyāna Faith is a Chinese composition, not a translation of an Indian original. Its philosophical value should be understood in that context. It does not belong to the internal development of Indian Buddhism. Chinese thinkers independently developed this philosophical synthesis after assimilating tathāgatagarbha and consciousness-only materials transmitted from India. Recognizing its origin does not diminish its value, but it should not be cited as a representative of the Indian tradition.

One mind, two gates: the structure

The core framework of the Awakening of Faith is "one mind opening into two gates":

The "one mind" is the tathāgatagarbha mind, the origin of all dharmas. It has a gate of suchness, its static, absolute, pure aspect, and a gate of arising and ceasing. The latter is its dynamic aspect that responds to conditions, in which defilement and purity coexist.⁵

The philosophical intent of this structure is to integrate the pure nature of tathāgatagarbha (the gate of suchness) and the activity of the storehouse consciousness (the gate of arising and ceasing) into a unified system. It seeks to explain how delusion (saṃsāra) and awakening (liberation) both spring from the "one mind," and how one moves from the obscuration of ignorance (avidyā) toward "acquired awakening."

Original awakening and acquired awakening

Another central pair of concepts in the Awakening of Faith is original awakening and acquired awakening.

Original awakening means that the mind of a sentient being is already awakened in its nature. The pure aspect of tathāgatagarbha is precisely original awakening. It is an awakened nature that has always been present, rather than a potential.

Acquired awakening means the awakening that gradually unfolds through practice. Practice brings it into ever closer accord with "original awakening," the awakened nature already present. When acquired awakening finally accords completely with original awakening, ultimate awakening occurs. The original and the acquired become one.

The framework gives practice the role of recognizing awakening rather than creating it, since original awakening is already there. The awareness unfolding through practice (acquired awakening) gradually recognizes and accords with its already existing, originally awakened nature (original awakening).

The philosophical problems of the Awakening of Faith

The synthesis proposed by the Awakening of Faith has drawn criticism from three perspectives:

From the Madhyamaka standpoint, the "tathāgatagarbha mind" of the gate of suchness is described as an originally pure, permanent, unchanging "essence." It comes very close to ātman. However one explains it, a "permanent, unchanging essence" must be negated under Madhyamaka's thoroughgoing analysis of emptiness.

From the consciousness-only standpoint, Xuanzang's Faxiang school firmly rejects the framework of the Awakening of Faith. It regards the text as confusing the levels at which consciousness operates. The claim that all sentient beings inherently possess an awakened nature also directly conflicts with the consciousness-only doctrine of the "five lineages." Under that doctrine, different capacities carry different possibilities of attaining Buddhahood.

Viewed from early Buddhism, the claim of "original awakening," that sentient beings are already awakened, differs fundamentally from the position that awakening results from effort in practice. Why does an already awakened being remain in saṃsāra? The Awakening of Faith answers that it is obscured by ignorance. But the answer leaves the origin of ignorance unexplained, since it does not explain how an originally awakened mind can become obscured. The problem is exactly the tathāgatagarbha tradition's old question of how defilement is possible in what is originally pure.⁶ The compatibility of original awakening with practice must be distinguished here from the origin of ignorance. Tiantai gives a direct answer to the former. In the "six identities," "identity" acknowledges what is inherently present, while "six" orders the stages. The two aspects coexist on distinct levels (Chapter 7.4). The origin of ignorance falls outside the scope of the six identities and remains an unresolved question within the framework of the Awakening of Faith.

5. The overall relationship among the three discourses¶

The relationship of tathāgatagarbha to Madhyamaka and consciousness-only can be drawn together in a single diagram:

The Laṅkāvatāra Sūtra identifies tathāgatagarbha with the storehouse consciousness. The chapter also presents a Madhyamaka critique of positive claims about an intrinsically pure ground. The Chinese source diagram places Paramārtha, his ninth consciousness, and the development of the Awakening of Faith in China in that order. The connecting lines do not establish transmission lineages.

The diagram shows no progression from problem to solution. It describes an open process that begins from a shared starting point, Prajñāpāramitā emptiness. The traditions repeatedly diverge, criticize one another, and attempt syntheses that produce further tensions.

6. In India and in China¶

In India

Philosophical discussion in the Indian tathāgatagarbha tradition took place mainly within the consciousness-only framework, through the equation made in the Laṅkāvatāra Sūtra. Prāsaṅgika Madhyamaka largely bypassed tathāgatagarbha's positive claims or incorporated them into emptiness. India produced no major thinker who systematically integrated all three discourses. Śāntarakṣita came closest, but his synthesis was chiefly of Madhyamaka and consciousness-only; tathāgatagarbha remained in the background rather than the foreground.

In India, tathāgatagarbha remained one voice within the larger body of scriptural literature and never formed an independent philosophical school. It lacked a commentarial tradition and scholastic teaching of its own, and did not develop the elaborate internal debates found in Abhidharma or consciousness-only.²

In China

After tathāgatagarbha entered China, the situation was almost the reverse. It became central to Chinese Buddhism through the Awakening of Faith and the Nirvāṇa Sūtra's universal declaration that all sentient beings possess Buddha-nature. Tiantai and Huayan also each developed doctrinal systems centered on tathāgatagarbha.

China had no tradition of Candrakīrti-style Prāsaṅgika Madhyamaka to subject tathāgatagarbha to rigorous philosophical criticism; the influence of the Madhyamaka Three Treatise school was limited. Consciousness-only, or the Faxiang school, directly conflicted with tathāgatagarbha over the five lineages, but its Chinese transmission soon declined.

In the absence of strong internal criticism, tathāgatagarbha thought in China developed into a relatively coherent framework with quite blurred philosophical boundaries. The mind's original purity, the all-pervasiveness of Buddha-nature, and original awakening acquired far greater influence in China than in India. These concepts profoundly shaped Chan's formulation "see one's nature and become a Buddha," Tiantai's doctrine of inherent inclusion, and Huayan's dependent origination from tathāgatagarbha. Essay 10 discusses these doctrines in detail.

7. This book's assessment¶

Tathāgatagarbha is an independent philosophical impulse that cannot be fully absorbed into either Madhyamaka or consciousness-only.

Incorporating tathāgatagarbha into Madhyamaka as "a positive expression of emptiness" is the most philosophically rigorous approach. In effect, however, it eliminates tathāgatagarbha's independent content. "Nonempty tathāgatagarbha" can no longer be taken seriously, and all the tradition's positive claims about inherently present qualities of Buddha-nature are removed. The result is too far from the original intent of tathāgatagarbha texts and their traditional usage.

Incorporating tathāgatagarbha into consciousness-only as "the pure aspect of storehouse consciousness" has been more effective historically. It gives tathāgatagarbha a philosophical vocabulary for describing its operations. Yet it merely reformulates the fundamental tension. The coexistence of contaminated and pure aspects within a single consciousness remains unresolved.

The philosophical problems of tathāgatagarbha have still received no fully satisfactory answer.

None of the syntheses discussed in this section truly resolves the contradictions between purity and defilement, original awakening and saṃsāra, or inherently possessed Buddha-nature qualities and the necessity of practice. They only accommodate and reformulate them to varying degrees. The third received a separate, systematic answer in China, in Tiantai's classification of stages through the six identities (Chapter 7.4). The answer addresses only the compatibility of inherent possession with practice and realization. The first two contradictions fall outside its scope, and this section's judgment remains valid for them.

Yet the question raised by tathāgatagarbha is real.

Tathāgatagarbha asks what guarantee at the level of existence makes liberation possible. If everything is empty and conventionally designated, what is practice directed toward? Madhyamaka and consciousness-only each leave gaps in their accounts of liberation. Tathāgatagarbha fills the gap with "the pure Buddha-nature that was already there." The philosophical attempt has a real motivation, even though it brings new difficulties.
