[3] His posthumous name was Ci'en Dashi (慈恩大師; 'Master Ci'en'), the Great Teacher of Cien Monastery, after the Daci'en Temple or Great Monastery of Compassionate Grace, which was located in Chang'an, the main capital of the Tang Dynasty.

According to biographies, he was sent to the imperial translation bureau headed by Xuanzang, from whom he later would learn Sanskrit, Abhidharma, and Yogācāra.

[4] Kuiji collaborated closely with Xuanzang on the Cheng weishi lun, a redacted translation of commentaries on Vasubandhu's Triṃśikā-vijñaptimātratā.

[4] Kuiji's commentaries on the former text, the Cheng weishi lun shuji, along with his original treatise on Yogācāra, the Dasheng Fayuan yilin chang (大乘法苑義林章; "Essays on the Forest of Meanings in the Mahāyāna Dharma Garden") became foundations of the Faxiang School, the dominant school of Yogācāra thought in East Asia.

[3] He is accordingly considered the founder of this school which differed notably from Paramārtha's earlier Chinese Yogācāra system.
