The Weishi ershi lun; Vim!/satika^ vijn~apti-ma^trata^-siddhih!， Vimsatika^-vr!tti （Twenty Verses on Consciousness-only）. T 1590.31.74-77. By Vasubandhu 世亲， translated in 661 by Xuanzang 玄奘. There are also translations by Prajn~a^ruci （唯识论） and Parama^rtha （大乘唯识论）. This was one of Vasubandhu's most philosophically important Yoga^ca^ra works， which refutes the realism of the non-Buddhist and pre-Maha^ya^na schools. Hamilton translated Xuanzang's version and Kuiji's commentary （述记）. Translations not from Chinese include Anacker （1984） and Kochumuttom （1982）.
