This collection includes the Vada-Vidhi, a work on logic; the Pancaskandhakaprakarana, which deals with the 'aggregates' making up 'personality', the karmasiddhiprakarana, which attacks many features of earlier Buddhist psychology, the Vimsatika and Trimsika, which take Buddhist psychology into hitherto unexplored areas; the Madhyanta-vibhagabhasya, books of Mahayana realization: and the Tri-svabhav-nirdesa, which shows a way for ridding consciousness of ensnaring mental constructions.
Vasubandhu (Sanskrit: वसुबन्धु; traditional Chinese: 世親; pinyin: Shìqīn; Tibetan: དབྱིག་གཉེན་, Wylie: dbyig gnyen) (fl. 4th century) was an Indian Buddhist monk and, along with his putative half-brother Asanga, one of the main founders of the Indian Yogācāra school.
Vasubandhu is one of the most influential figures in the entire history of Buddhism, and is held to have introduced formal logic to the Buddhist epistemological tradition. In the Jodo Shinshu branch of Buddhism, he is considered the Second Patriarch; in Zen, the 21st Patriarch.
