Asanga in the context of "Hossō"

East Asian Yogācāra refers to the Mahayana Buddhist traditions in East Asia which developed out of the Indian Buddhist Yogācāra (lit. "yogic practice") systems (also known as Vijñānavāda, "the doctrine of consciousness" or Cittamātra, "mind-only"). In East Asian Buddhism, this school of Buddhist idealism was known as the "Consciousness-Only school" (traditional Chinese: 唯識宗; ; pinyin: Wéishí-zōng; Japanese pronunciation: Yuishiki-shū; Korean: 유식종).

The 4th-century brothers, Asaṅga and Vasubandhu, are considered the classic founders of Indian Yogacara school. The East Asian tradition developed through the work of numerous Buddhist thinkers working in Chinese. They include Bodhiruci, Ratnamati, Huiguang, Paramārtha, Jingying Huiyuan, Zhiyan, Xuanzang and his students Kuiji, Woncheuk and Dōshō.

The Aṣṭasāhasrikā Prajñāpāramitā Sūtra (Sanskrit: अष्टसाहस्रिका प्रज्ञापारमिता सूत्र; English: The Perfection of Wisdom in Eight Thousand [Lines]) is a Mahāyāna Buddhist sūtra in the category of Prajñāpāramitā sūtra literature. The sūtra's manuscript witnesses date to at least c. 184 BCE – c. 46 BCE, making it among the oldest Buddhist manuscripts in existence. The sūtra forms the basis for the expansion and development of the Prajñāpāramitā sūtra literature. In terms of its influence in the development of Buddhist philosophical thought, P.L. Vaidya writes that "all Buddhist writers from Nāgārjuna, Āryadeva, Maitreyanātha, Asaṅga, Vasubandhu, Dignāga, down to Haribhadra concentrated their energies in interpreting Aṣṭasāhasrikā only," making it of great significance in the development of Madhyāmaka and Yogācāra thought.

The sūtra deals with a number of topics, but is primarily concerned with the conduct of a bodhisattva, the realisation and attainment of the Perfection of Wisdom as one of the Six Perfections, the realisation of thusness (tathātā), the attainment of irreversibility on the path to buddhahood (avaivartika), non-conceptualisation and abandonment of views, as well as the worldly and spiritual benefit of worshipping the sūtra.

The Mahayana sutras are Buddhist texts that are accepted as canonical and authentic buddhavacana in Mahayana Buddhist sanghas. These include three types of sutras: Those spoken by the Buddha; those spoken through the Buddha's blessings; and those spoken through mandate. They are largely preserved in Sanskrit manuscripts, and in translations such as the Tibetan Buddhist canon, and Chinese Buddhist canon. Several hundred Mahāyāna sutras survive in Sanskrit, Tibetan and Chinese translations. The Buddhist scholar Asanga classified the Mahāyāna sūtras as part of the Bodhisattva Tripiṭaka, a collection of texts meant for bodhisattvas.

Buddhists consider the most important Mahayana sutras to be the spoken teachings of Shakyamuni Buddha. These were quickly recorded one year following his Mahaparinirvana, when the Buddha's main attendant Ananda recited these Sutras in their entirety at the First Buddhist Council, where they were recorded. At that Council, two other attendants recited two other classifications of the Buddha's teachings. Other Mahāyāna sūtras are presented as being taught by masters such as bodhisattvas like Mañjuśrī and Avalokiteśvara. There are various reasons that Indian Mahāyāna Buddhists give to explain why some Sutras appeared at later times. One such reason is that they had been hidden away in the land of the Nāgas (snake deities, dragons) until the proper time for their dissemination arrived. They are also sometimes called Vaipulya ("extensive") sūtras by earlier sources.

Vasubandhu (traditional Chinese: 世親; ; pinyin: Shìqīn; Tibetan: དབྱིག་གཉེན་ Wylie: dbyig gnyen; fl. 4th to 5th century CE) was an influential Indian Buddhist monk and scholar. He was a philosopher who wrote commentary on the Abhidharma, from the perspectives of the Sarvastivada and Sautrāntika schools. After his conversion to Mahayana Buddhism, along with his half-brother, Asanga, he was also one of the main founders of the Yogacara school.

Vasubandhu's Abhidharmakośakārikā ("Commentary on the Treasury of the Abhidharma") is widely used in Tibetan and East Asian Buddhism, as the major source for non-Mahayana Abhidharma philosophy. His philosophical verse works set forth the standard for the Indian Yogacara metaphysics of "appearance only" (vijñapti-mātra), which has been described as a form of "epistemological idealism", phenomenology and close to Immanuel Kant's transcendental idealism. Apart from this, he wrote several commentaries, works on logic, argumentation and devotional poetry.

Maitreya-nātha (c. 270–350 CE) is a name whose use was pioneered by Buddhist scholars Erich Frauwallner, Giuseppe Tucci, and Hakuju Ui to distinguish one of the three founders of the Yogācāra school of Buddhist philosophy, along with Asanga and Vasubandhu. Some scholars believe this Maitreya to be a historical person in India who authored various Yogācāra texts known as the Maitreya corpus. The traditions themselves have held that it is referring to the bodhisattva Maitreya, the future buddha.
