Vasubandhu (Sanskrit: वसुबन्दु; traditional Chinese: 世親; pinyin: Shìqīn; Tibetan: དབྱིག་གཉེན་, Wylie: dbyig gnyen) (fl. 4th c.) was an Indian Buddhist monk, and along with his half-brother Asanga, one of the main founders of the Indian Yogācāra school. However, some scholars consider Vasubandhu to be two distinct people. Vasubandhu is one of the most influential figures in the entire history of Buddhism. In the Jodo Shinshu branch of Buddhism, he is considered the Second Patriarch. In Zen, he is the 21st Patriarch.
