Asanga (4th Century)

Three Brothers from the Same Brahmin Family

Tradition places Asanga’s birth in Puruṣapura, today Peshawar in Pakistan, then the capital of the kingdom of Gandhāra, in a Brahmin family^[23]. Dates vary considerably among modern authors—from the mid-3rd to the 5th century—but several key reference syntheses favor the range c. 300–390, placing Asanga in the 4th century — while others, such as the Britannica, place him in the 5th century, and the Universalis between the 4th and 6th centuries^{[24] [25]}. The Tibetan testimony of historian Buton Rinchen Drub (1290–1364), however, locates the birth of the two brothers in central India rather than Gandhāra—a divergence reported by the consulted WPEN synthesis, which does not decide between the two locations^[26].

Asanga was the eldest of three brothers, all of whom became monks. The youngest, Vasubandhu, would become the second great Yogācāra master; the role of the third brother, sometimes named Viriñcivatsa in tradition, remains marginal in the sources^[27]. According to a tradition reported by some authors, Asanga’s father was of the kshatriya caste while Vasubandhu’s father was Brahmin—making the two brothers maternal half-brothers rather than full siblings^[28]. This genealogical detail, unevenly transmitted across sources, does not change the essential fact: the two men grew up and were educated together in Puruṣapura before taking doctrinally divergent, then convergent, paths.

Training in the Mahīśāsaka School and Doubt Regarding Emptiness

Having become a monk, Asanga received his initial training in a Hīnayāna school—according to the Chinese pilgrim Xuanzang, he first belonged to the Mahīśāsaka school before turning to the Mahāyāna; other sources mention an initial affiliation with the Mūlasarvāstivādin school^[29]. This training gave him a deep technical mastery of abhidharma—the scholastic analysis of psychic and material phenomena—which he retained and reworked throughout his life, even after his conversion to the Great Vehicle.

According to biographical tradition, Asanga then spent many years in solitary meditation and study, seeking to deepen his understanding of the doctrine of emptiness (śūnyatā) without achieving the intellectual and spiritual satisfaction he sought^[30]. It was this prolonged dissatisfaction that, according to the traditional account, led him to the most famous episode of his life: the encounter with Maitreya.

The Account of Paramārtha and Xuanzang

The oldest and most detailed account of this episode comes from the Chinese monk Paramārtha (499–569), one of the great translators and transmitters of Yogācāra in China, in his biography of Vasubandhu^[31]. According to this account, Asanga used his meditative powers (siddhi) to ascend by night to the heaven of Tuṣita and there receive from Maitreya the teaching of the Great Vehicle, notably on emptiness and on texts that would become the doctrinal core of Yogācāra^[32].

A century later, the Chinese pilgrim Xuanzang (602–664), who himself studied the Yogācāra tradition in India before bringing it back and spreading it in China, confirms this episode in his travelogue, the Records of the Western Regions:

“At night, he ascended to the bodhisattva Maitreya in the Tuṣita heaven to learn the Yogācārabhūmi-śāstra, the Mahāyāna-sūtra-alaṃkāra-śāstra, the Madhyānta-vibhāga-śāstra, and other texts.” — Xuanzang, Records of the Western Regions (Da Tang Xiyu Ji), 7th century, English trans. Rongxi (1996); working French translation^[33]

Xuanzang geographically situates this episode near Ayodhyā: it is in the section of his account devoted to the country of Ayodhyā that he reports having seen, “in a great mango grove five or six li to the southwest of the city, an old monastery” where “the bodhisattva Asaṅga received his instructions and guided the common people” — English text checked against the Rongxi translation^[34]. The account adds that Asanga then taught the doctrine he received by night during the day, before a growing assembly of disciples.

The Historians’ Debate: Human Teacher or Mystical Vision?

Modern Yogācāra specialists are divided on the exact nature of this encounter. Part of the scholarship, including Austrian Indologist Erich Frauwallner, considers Maitreya—often called Maitreyanātha in this role, distinct from the future eponymous Buddha—to have been a historical human teacher active around 270–350, of whom Asanga was a disciple before developing and systematizing his teaching^[35]. Other researchers reject this euhemeristic reading and view the traditional account as describing a visionary meditation experience, with Maitreya playing the role of a tutelary deity (iṣṭa-devatā) rather than a flesh-and-blood teacher^[36].

This debate remains unresolved: no independent source today can verify the historical existence of a “Maitreyanātha” distinct from the celestial bodhisattva. What is more firmly established, however, is that tradition—both Chinese and Tibetan—consistently attributes to Maitreya the ultimate authorship of a foundational corpus of texts that Asanga then transmitted, commented on, and developed—hence the established expression of the “five treatises of Maitreya,” discussed further below.

Cittamātra and vijñaptimātra: "nothing but representation"

The very name of the school indicates its method: Yogācāra, "the practice (ācāra) of yoga," designates a path to salvation based on meditative discipline rather than mere speculation^[37]. But the school is also known by two other names that summarize its central philosophical thesis: Vijñānavāda, the "doctrine of consciousness," and Cittamātra, "nothing but thought" — or, in a more precise formula used by some texts, vijñaptimātra, "nothing but representation"^[38].

The central thesis, developed from earlier sources such as the Saṃdhinirmocana-sūtra, holds that the objects we believe we perceive in the external world have no independent existence apart from the mind that perceives them: they are representations (vijñapti) produced by consciousness itself, not things existing by themselves outside it^[39]. According to the synthesis given by the Encyclopédie Universalis, for this school, "absolute reality is nothing other than thought"; the teaching leads the practitioner, through meditation, to make "thought think itself" and "see itself" and "know itself with discernment"^[40]. From this perspective, the perceptions of an awakened man, a mentally ill person, a dreamer, or a yogin in deep absorption have, from a strictly epistemological point of view, the same value: they are all constructions of consciousness^[41].

The ālayavijñāna, the storehouse consciousness

The most original and systematically developed concept by Asanga is that of ālayavijñāna, the "storehouse consciousness" or "repository consciousness"^[42]. This eighth form of consciousness — added to the six classical sensory consciousnesses and the mental consciousness — serves as a continuous support where the traces of all past actions are deposited in the form of "seeds" (bīja), and from which future experiences sprout in return. The Mahāyānasaṃgraha itself, in its first chapter, presents the ālayavijñāna, following an ancient sūtra, as the beginningless support common to all phenomena and the foundation of every destiny up to nirvana; Asanga then explains this name of "storehouse" by a reciprocal cause-to-fruit relation between this consciousness and the defiled phenomena of beings who are reborn (working paraphrase based on the Lamotte translation, given as such and not as a verified quotation)^[43]. This storehouse consciousness thus accounts, without resorting to a permanent substantial self, for the continuity from one existence to another through the cycle of rebirths — one of the classical problems that any Buddhist school faithful to the doctrine of non-self (anātman) had to solve^[44]. For the general doctrine of non-self, karma, and rebirth in Buddhism, see the dedicated article: Buddhism.

The three natures according to the trisvabhāva

To explain the exact status of this "consciousness alone" and its relation to the appearances of the world, Yogācāra develops the doctrine of the three natures (trisvabhāva), which distinguishes three levels of reality of phenomena^[45]:

This framework is not a mere scholastic exercise: it allows the Yogācāra school to respond to the accusation, notably from proponents of the Madhyamaka, that denying any external reality amounts to nihilism incompatible with the Buddhist doctrine of emptiness. For Asanga and his successors, it is not the existence of the dependent mental flow (paratantra) that is denied, but only the false superimposition of independent substantial objects on this flow — emptiness consisting precisely in the absence, within the real flow of phenomena, of the subject-object duality that the unenlightened mind projects there^[46].

The Yogācārabhūmi-śāstra: Compilation or Single Treatise?

The largest text traditionally attributed to Asanga is the Yogācārabhūmi-śāstra, "Treatise on the Stages of Yoga Practice," a monumental encyclopedia covering the stages of the bodhisattva's spiritual path^[47]. Modern philological research, identifying several textual layers of different styles and periods within the work, now mostly considers it a compilation gathering contributions from multiple authors over an extended period, rather than a text composed in one go by a single hand^[48]. This does not exclude that Asanga personally participated in its compilation or final redaction, but it calls for caution in attributing the entire text solely to him^[49][50].

The Mahāyānasaṃgraha, the Sum of the Great Vehicle

The work whose attribution to Asanga enjoys the broadest scholarly consensus is the Mahāyānasaṃgraha — the "Sum of the Great Vehicle" — a systematic exposition in ten chapters of the fundamental theses of Yogācāra, considered his masterwork^[51]. The original Sanskrit text is lost, but the work survives in a Tibetan translation and in four successive Chinese translations, including that by Xuanzang himself^[52]. It was the Belgian Indologist Étienne Lamotte (1903–1983), professor at the University of Louvain, who established the critical edition of reference in a Western language, with a Tibetan translation and commentary comparing the Chinese versions, published in two volumes by the Oriental Institute of Louvain in 1938 and reissued in 1973^[53]. Nearly a century after its first publication, this edition remains the essential tool for French-language research on classical Yogācāra.

The Abhidharmasamuccaya and Disputed Commentaries

The Abhidharmasamuccaya, a brief systematic summary of Mahāyāna Abhidharma doctrines preserved in Sanskrit, completes the core of works unanimously attributed to Asanga^[54]. Two other texts are sometimes attributed to him — a verse compilation commenting on the Vajracchedikā (Diamond Sutra), the Kārikāsaptati, and a commentary on the Saṃdhinirmocana-sūtra — but these attributions, less firmly established, do not enjoy general acceptance among contemporary scholars^[55].

The Five Treatises of Maitreya: A Disputed Attribution

The Tibetan tradition groups under the name of the "five treatises of Maitreya" a set of texts that Asanga is said to have received in Tuṣita and transmitted to the human world: the Mahāyānasūtrālaṃkāra, the Madhyāntavibhāga, the Dharmadharmatāvibhāga, the Abhisamayālaṃkāra, and the Ratnagotravibhāga^[56]. However, several of these attributions are seriously questioned by modern research, according to the consulted encyclopedic synthesis: the very formula of the "five works of Maitreya" is reportedly attested in Sanskrit sources only from the 11th century, which calls for particular caution regarding the actual antiquity of this grouping^[57]. The Abhisamayālaṃkāra, absent from the Chinese tradition, is attributed by some scholars to an Indian author other than Maitreya, while the Ratnagotravibhāga is, according to the Chinese tradition itself, the work of an author other than Maitreya — an antiquity and unity of attribution that modern research, still according to this synthesis, judges unlikely before the 11th century (exact references of the works cited by the synthesis not re-verified)^[58]. Only two texts in the group — the Mahāyānasūtrālaṃkāra and the Madhyāntavibhāga — enjoy a relatively broader consensus regarding an authentic, direct or indirect, link with the teaching received by Asanga.

This philological caution does not diminish the historical importance of the corpus: whether these texts are, in whole or in part, Asanga’s own work, his formulation of a received teaching, or the work of later disciples placed under Maitreya’s authority according to a common practice in Indian literature, they together constitute the doctrinal foundation on which the entire classical Yogācāra school was built.

Having become a renowned sarvāstivādin monk and author of the Abhidharmakośa — a major scholastic summa of non-Mahāyāna Buddhism — Vasubandhu openly criticized his elder brother’s work. According to the traditional account reported by Paramārtha, Vasubandhu, upon discovering the scope of the Yogācārabhūmi compiled by Asanga, exclaimed:

“Alas, Asanga, withdrawn in the forest, practiced meditation for twelve years [...] ; he founded a system so difficult and so heavy that a single elephant could carry it.” — Vasubandhu, cited by Paramārtha, Biography of Master Vasubandhu (Po-seou-p'an-teou fa-che tchouan), 6th century^[59]

Alarmed by his brother’s hostility toward Mahāyāna and concerned for his spiritual future, Asanga is said to have feigned illness to draw Vasubandhu to his bedside, seizing the opportunity to explain in detail the doctrine of the Great Vehicle^[60]. According to Xuanzang, the actual conversion took place at Ayodhyā, where Vasubandhu, having asked his brother to expound the Mahāyāna teaching, immediately recognized its superiority^[61]. Having himself become one of the greatest Yogācāra scholars, Vasubandhu produced major commentaries on his brother’s works and on the treatises of Maitreya — his life, his own doctrine (notably the Viṃśatikā and the Triṃśikā), and the chronological puzzle posed by the theory, now abandoned by research, of “two Vasubandhus” formulated by Erich Frauwallner, will be the subject of a dedicated article: Vasubandhu^[62].

According to the Tibetan historian Tāranātha (1575-1634), author of a History of Buddhism in India which remains one of the main late sources on this period, Asanga founded, in chapter 22 of this work, a vihāra in a forest called Veluvana — variant Piluvana in some editions — where he taught the Mahāyāna doctrine to eight disciples learned in the moral vows and the sūtras, a place that became famous as the Dharmāṅkura-vihāra and where he put the five treatises of Maitreya into written form^[63]. This Veluvana is not the famous Bamboo Grove of Rājagṛha offered to the Buddha by King Bimbisāra: the translator’s note identifies it, following Xuanzang, as a place east of Ayodhyā, in a mango grove^[64]. The figure of “twenty-five monasteries,” repeated by some modern syntheses, appears in no passage of Tāranātha’s work and is therefore removed here.

The Tibetan tradition also counts Asanga among the “seventeen great masters/scholars of Nālandā” (paṇḍita), a pantheon of major doctrinal authorities associated with the prestigious monastic university of Nālandā, in Magadha, one of the greatest centers of Buddhist study in ancient Asia^[65]. This late association, more honorary than historically documented in Asanga’s case — Nālandā itself having been founded only in the 5th century —, nonetheless attests to the central place that later tradition has recognized for him in the transmission of institutional Buddhist knowledge.

The thought of Asanga and Vasubandhu experienced a particularly rich second life in China, where it was transmitted from the 6th century by Paramārtha, then systematized and spread in the 7th century by Xuanzang himself, after his own study sojourn in India, giving rise to the Chinese school Faxiang (“characteristics of dharmas”), which in turn influenced Japanese Buddhism under the name Hossō^[66]. In Tibet, where the five treatises of Maitreya and the major works of Asanga and Vasubandhu have been the subject of extensive translation, commentary, and monastic teaching since the 11th century, the Cittamatra tradition remains today one of the four great schools of Buddhist philosophy studied in the classical monastic curriculum, alongside Madhyamaka, Sautrāntika, and Vaibhāṣika^[67].

A Correct Intuition: The Instability of the World and the Primacy of Interior Experience

The Second Vatican Council, in its declaration Nostra Aetate, acknowledges that Buddhism, “in its various forms,” perceives “the radical insufficiency of this changing world” and teaches “a way by which men, with a devout and trusting heart, may acquire the state of perfect liberation”^[68]. This recognition applies with particular force to the school founded by Asanga: the meticulous analysis that Yogācāra makes of the mechanisms of perception, desire, and attachment shows a genuine lucidity about the instability and constructed nature of our representations of the world, and the meditative discipline it proposes to purify the mind of its false projections resonates, on a strictly ascetic level, with the Christian emphasis on guarding the heart and inner purification. A Catholic has no reason to disdain the psychological sophistication and analytical rigor of Asanga’s corpus on this precise point — the Church, in the same paragraph of Nostra Aetate, “rejects nothing that is true and holy in these religions”^[69].

A Decisive Divergence: The Real World Created, Not a Mere Representation

The most radical divergence, however, concerns the very status of the world. For Yogācāra, as summarized by the Encyclopédie Universalis, “absolute reality is nothing other than thought” — the objects of the external world have, strictly speaking, no existence independent of the consciousness that represents them^[70]. Catholic faith, by contrast, affirms from its very first article of faith that God has really created a material world distinct from Himself and endowed with its own consistency: “I believe in God, the Father almighty, creator of heaven and earth.” The world is not a projection of human consciousness, nor even an emanation of divine consciousness devoid of real otherness: it is a gift, distinct from its Creator, whose own reality — matter, causality, time, space — is not an illusion to be dissolved by meditation but a good work to be contemplated, known, and cultivated (Gn 1:31). On this precise point, the Catholic doctrine of creation stands in direct opposition to cittamātra idealism: to know, for the Catholic tradition, is to intellectually grasp something that really exists outside the knowing mind, not to construct or project this reality by the very act of knowing.

The ālayavijñāna versus the Created Spiritual Soul

The concept of ālayavijñāna deserves particular attention because it addresses, in its own way, a real difficulty: how to account for the continuity of existence, memory, and moral responsibility without recognizing a permanent substantial self — the doctrine of non-self (anātman) forbids this in principle? Asanga answers with an impersonal flow of “seeds” that are transmitted without ever constituting a stable subject^[71].

Catholic faith answers the same requirement — to account for personal identity and continuity — by a radically different path: the affirmation of a spiritual soul, immaterial, immortal, and personally created by God for each human being:

“The Church teaches that each spiritual soul is immediately created by God — it is not ‘produced’ by the parents — and that it is immortal: it does not perish when it separates from the body at death, and it will be reunited with the body at the final resurrection.” — Catechism of the Catholic Church, §366^[72]

Where ālayavijñāna dissolves the question of the subject into an endless causal flow of impersonal seeds, Catholic doctrine of the spiritual soul maintains that there exists, in each person, a subject truly one and permanent, willed and created by God as such, called to the resurrection of the body and not to extinction or final dissolution into a flow of consciousness. The dignity of the human person — the foundation of all Catholic morality and law — rests precisely on this affirmation of a stable and responsible subject, which the logic of Buddhist non-self, however refined in its treatment of psychological continuity, ultimately cannot ground in the same way.

Nirvana and Beatific Vision: Extinction or Personal Communion?

The ultimate goal proposed by Yogācāra — as by Buddhism as a whole — is the cessation of suffering and the escape from the cycle of rebirths through the realization of emptiness, the mind coming to “see” and “know” itself at the end of the meditative path^[73]. This goal remains, in its deepest structure, an impersonal fulfillment: it is not a meeting between two persons, but the dissolution of illusions that obstruct the correct knowledge of the emptiness of all phenomena, including the subject itself. The ultimate destiny promised by the Catholic faith is of a completely different nature: a personal communion with a God who is Himself personal, in the face-to-face vision:

“Those who die in God’s grace and friendship, and are perfectly purified, live forever with Christ. They are forever like God, because they see Him ‘as He is’ (1 Jn 3:2), face to face.” — Catechism of the Catholic Church, §1023^[74]

This “beatific vision” is by no means the dissolution of a subject into an impersonal flow of purified consciousness: on the contrary, it presupposes two truly distinct persons — the created soul and the Creator God — united in an act of knowledge and love that neither suppresses, but rather elevates both to the highest point of their possible relationship. For the broader Catholic critique of non-self, karma, and the cycle of rebirths, developed for all of Buddhism, see Buddhism and why reincarnation is a false belief.
