Asaṅga (Sanskrit: असङ्ग, Tibetan: ཐོགས་མེད།, Wylie: thogs med, traditional Chinese: 無著; ; pinyin: Wúzhuó; Romaji: Mujaku) (fl. 4th century C.E.) was one of the most important spiritual figures of Mahayana Buddhism and the founder of the Yogachara school.[1][2][3] Traditionally, he and his half-brother Vasubandhu are regarded as the major classical Indian Sanskrit exponents of Mahayana Abhidharma, Vijñanavada (awareness only; also called Vijñaptivāda, the doctrine of ideas or percepts, and Vijñaptimātratā-vāda, the doctrine of 'mere representation)) thought and Mahayana teachings on the bodhisattva path. He is also traditionally considered as one of the seventeen Nalanda masters who taught at the monastery which is located in modern-day Bihar.[4]
Vasubandhu (traditional Chinese: 世親; ; pinyin: Shìqīn; Tibetan: དབྱིག་གཉེན་ Wylie: dbyig gnyen; fl. 4th to 5th century CE) was an influential Buddhist monk and scholar from Gandhara. 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.
