Wei-shih san-shih lun sung; the Trim!/sika^ Vijn~aptima^trata^siddhih! （Thirty Verses on Consciousness-only; 1 fasc.， by Vasubandhu 世亲， trans. Xuanzang 玄奘. A representative work by Vasubandhu which is one of the most important texts for the establishment of Yoga^ca^ra doctrine， wherein the most important principles heretofore explained by Maitreya 弥勒 and Asan%ga 无著 are skillfully and economically re-explained from the standpoint of the transformation of consciousness （识转变， vijn~a^na-parin~a^ma） in a short thirty verses. Since Vasubandhu passed away without having ever written explanatory commentary on these verses， succeeding generations of scholars engaged in extensive debate over their interpretation， to the extent that various schools of Yoga^ca^ra developed. Among these interpretations， it was that by Dharmapa^la 护法 which came to be taken as orthodox. This commentary by Dharmapa^la formed the major content of the Vijn~aptima^trata^siddhi-/sa^stra， which was translated into Chinese by Xuanzang 玄奘 as the Cheng weishi lun 成唯识论， in turn an important text in the formation of the Chinese Faxiang school 法相宗.
