Vasubandhu

Two careers, one philosopher

The traditional biography of Vasubandhu — preserved most carefully in Paramārtha's sixth-century Chinese Life and reconstructed cautiously by twentieth-century scholarship — describes a single figure who in the fourth or fifth century CE composed two substantially different philosophical corpora separated by a religious conversion. In the early career he wrote the Abhidharmakośa — Treasury of Higher Doctrine — a verse compendium of the Sarvāstivāda school's Abhidharma analysis of mind, matter, and the path, accompanied by his own commentary (bhāṣya) in which he criticised the Sarvāstivāda from a Sautrāntika standpoint. The text became the canonical Abhidharma textbook of subsequent East Asian and Tibetan monastic training; it is still memorised in the Tibetan shedra curriculum and remains the principal reference work for post-Nikāya Buddhist scholastic philosophy. In the later career — by the tradition's account, after his elder half-brother Asaṅga converted him to the Mahāyāna§ — he produced the short, dense treatises that founded the Yogācāra§ school as a fully articulated philosophical system: Viṃśatikā (The Twenty Verses), Triṃśikā (The Thirty Verses), Trisvabhāva-nirdeśa (The Treatise on the Three Natures), and the commentary on Maitreya's Madhyāntavibhāga. Modern philological scholarship — particularly Erich Frauwallner's mid-twentieth-century work — proposed that the two corpora are the work of two distinct people who shared a name; the consensus has since drifted back, with caution, toward the traditional single-figure attribution, with the dating uncertain to within a century.

What Yogācāra claims

The Yogācāra§ school — the Practice of Yoga school, also called Cittamātra (Mind-Only) and Vijñānavāda (the doctrine of consciousness) — argued that what we ordinarily take to be external, mind-independent objects are more parsimoniously analysed as configurations of consciousness itself. The argument is not the cruder claim that nothing exists outside the mind; it is the technical claim that the appearance of subject-object duality in cognition is a constructive artefact of how consciousness operates, and that the felt distinction between a perceiver inside and a world outside is generated within the cognitive process rather than encountered prior to it. Vasubandhu's Twenty Verses defends this against realist objections; the Thirty Verses lays out the school's positive psychology — the eight consciousnesses (aṣṭa-vijñāna) culminating in the ālayavijñāna or storehouse consciousness, the substrate that carries karmic seeds (bīja) between moments and lifetimes, and in which the apparent self of the manas (the seventh consciousness, the self-grasping faculty) takes root. The Three Natures treatise then maps the relation between the parikalpita (the imagined or constructed nature), paratantra (the dependent or causally arising nature), and pariniṣpanna (the perfected or ultimate nature) — the school's account of how ordinary experience and awakening relate.

Vasubandhu and Nāgārjuna

The Yogācāra and the Madhyamaka — Nāgārjuna's§ school — are the two principal philosophical streams of Mahāyāna§ Buddhism, and the question of whether they teach the same thing in different idioms or two different things has organised post-canonical Buddhist philosophy for sixteen centuries. The Madhyamaka§ emphasises emptiness§ — the lack of intrinsic nature in any phenomenon — as the operative analysis; the Yogācāra emphasises the constructive activity of consciousness as the operative analysis. The Tibetan tradition's main reconciliation, the Yogācāra-Svātantrika-Mādhyamaka synthesis of Śāntarakṣita in the eighth century, treats them as compatible levels: the Yogācāra account of mind is correct as a conventional analysis; the Madhyamaka emptiness applies to the consciousness Yogācāra analyses as well as to its objects. The East Asian inheritance — the Tiantai§ and Tendai§ schools — went further and folded Yogācāra categories into a Buddha-nature framework that became one of the philosophical engines of Zen§, particularly in the way the storehouse consciousness was rethought as the empty, luminous ground rather than as a karmic substrate.

Where the lineage shows in the index

Vasubandhu's own treatises are not in this index — the Abhidharmakośa and the Triṃśikā are translated, but their English editions are scholarly rather than the contemporary teaching titles the index principally collects. What the index does carry is the downstream weight of his work in three distinct registers. *The Awakening of Faith in the Mahāyāna*↗, traditionally attributed to Aśvaghoṣa but in the form circulated in the East Asian tradition almost certainly composed in sixth-century China by an author working inside the Yogācāra inheritance, is the single text most responsible for the transmission of the ālayavijñāna doctrine and its Buddha-nature§ reading into the Chan, Zen§, and Korean Sŏn lineages — a text the index carries in the Hakeda translation. Junjirō Takakusu's *The Essentials of Buddhist Philosophy*↗, the principal twentieth-century survey of the East Asian doctrinal schools, devotes substantial sections to Yogācāra (under its East Asian name Hossō) and to the consequences of Vasubandhu's Triṃśikā for the later schools. Thich Nhat Hanh on emptiness, signlessness, and aimlessness↗ translates Yogācāra's storehouse-consciousness doctrine into Plum Village idiom under the seeds in the store consciousness image; his teaching on how true Buddhist instruction takes us directly to ultimate truth↗ extends the same psychology from the vijñaptimātratā analysis into the lived register of practice today. Both Pema Chödrön's *When Things Fall Apart*↗ and her course on awakening compassion↗ operate inside the Yogācāra-influenced Tibetan inheritance — the school's psychology of how the manas grasps at a self is, in modified form, what the bodhicitta and tonglen practices the course teaches are designed to address.

What he isn't

Vasubandhu is not, despite the way Cittamātra can read in casual exposition, a Buddhist idealist in the European-philosophical sense — the claim is not that the external world is unreal because the mind is the only reality, but that the subject-object structure in which the question real versus unreal is ordinarily posed is itself a constructive artefact. The distinction matters because the Yogācāra account is compatible with what the Madhyamaka would call empty dependent arising; the two schools are debating which analytical apparatus best captures the same phenomenology, not whether minds or objects exist. Nor is the ālayavijñāna a soul or a self in the sense the anātman§ doctrine rules out: it is a karmic continuant that itself lacks intrinsic nature, and the school's later development — particularly under Tiantai§ influence — treats the storehouse precisely as the ground that disappears when the self-grasping faculty does. And Vasubandhu was not the school's founder in the way Nāgārjuna founded Madhyamaka; the systematic articulation of Yogācāra began with his elder brother Asaṅga and the Bhūmi-class scriptures Asaṅga transmitted, and Vasubandhu's distinctive contribution is the philosophical compression and the Triṃśikā's thirty-verse summary that became the school's portable textbook.
