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.
