Cheng Weishi Lun

The Cheng Weishi Lun (Chinese: 成唯識論; pinyin: Chéng wéishì lùn), or Discourse on the Perfection of Consciousness-only is a comprehensive discourse on the central teachings of Yogacara, framed around Vasubandhu's seminal Yogacara work Triṃśikā-vijñaptimātratā ("Thirty Verses on Consciousness-only"). It was written by the Chinese monk Xuanzang in the 7th century CE. It is sometimes referred to as Vijñaptimātratāsiddhi, its equivalent name in the Sanskrit language.
