Dàojìng 道鏡 (Tang, fl. mid–late 7th c.)
A Tang Pure Land monk known principally for the Niànfó jìng 念佛鏡 KR6p0045 (T47N1966), composed jointly with 善道 Shàndào (note: a different person from 善導 Shàndǎo, although the names are easily confused). Lifedates not preserved. The Taishō colophon assigns the work to “Dàojìng (collected) and Shàndào (jointly collected)” (道鏡集 善道共集). The DILA Buddhist Studies Person Authority lists Dàojìng under id A001297.
The CANWWW catalogue entry for T47N1966 (div31.xml) classes Dàojìng’s role as unknown (resp ‘unknown’) with Shàndào as 共集 (“co-compiler”), reflecting the textual uncertainty about the precise division of authorial responsibility. The text is one of a number of Tang Pure Land popularising manuals; its dating is not securely fixed but the doctrinal content suggests a late-Tang or early Sòng provenance.
He is otherwise undocumented in the standard biographical literature. He is not the same person as the famous Tang Pure Land patriarch 善導 Shàndǎo (613–681), nor as the Yuán Buddhist scholar Dàojìng 道鏡 (different character: 道徑, in some sources).
