Vasubandhu

Vasubandhu (; Tibetan: དབྱིག་གཉེན་ ; 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 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.

Vasubandhu is one of the most influential thinkers in the Indian Buddhist philosophical tradition. Because of their association with Nalanda university, Vasubandhu and Asanga are amongst the so-called Seventeen Nalanda Masters. In Jōdo Shinshū, he is considered the Second Patriarch; in Chan Buddhism, he is the 21st Patriarch. Provided by Wikipedia
