As an important contribution to East Asian Yogācāra, Xuanzang composed the "Cheng Weishi Lun", or "Discourse on the Establishment of Consciousness Only." This work is framed around Vasubandhu's "Triṃśikā-vijñaptimātratā", or "Thirty Verses on Consciousness Only." In his commentary, Xuanzang upheld Dharmapāla's commentary on this work as being the correct one, and provided his own explanations of these as well as other views. This work was composed at the behest of Xuanzang's disciple Kuījī (632–682), and became a central work of East Asian Yogācāra. Xuanzang also promoted devotional meditative practices toward Maitreya. Xuanzang's disciple Kuiji wrote a number of important commentaries on Yogācāra texts and further developed the influence of this doctrine in China. He was recognized by later adherents as the first true patriarch of the school.
