Jingying Huiyuan (Chinese: 淨影慧遠, "Huiyuan of Jingying Temple", Japanese: Jōyō Eon; c. 523–592) was an eminent Chinese Buddhist scholar-monk of the Dilun branch of Chinese Yogācāra. He was a prolific commentator who wrote various commentaries on key Mahayana Sutras. He was the first Chinese author to write commentaries on the Pure Land Sutras (which still survive) and his commentary on the Contemplation Sutra influenced later Pure Land Buddhist figures like Daochuo and Shandao. Like later Pure Land figures, Huiyuan taught that even ordinary people could attain birth in the Pure Land through recitation of the Buddha Amitabha's name (nianfo).
Huiyuan's philosophy is a synthesis of Yogācāra and buddha-nature thought. He also advanced the doctrines of essence-function and the "dependent origination of the tathāgatagarbha" (Ch: 如來藏緣起, pinyin: rulaizang yuanqi), which holds that buddha-nature is the essence of both nirvāṇa and saṃsāra, both of which were seen as its "functions" (yong). Huiyuan synthesized this teaching with the Yogacara mind-only philosophy, identifying buddha-nature with the fundamental consciousness (ālāyavijñāna). Huiyuan's metaphysics was influential on later Huayan authors, like Fazang.
