This article investigates the Jingjiao text Zhixuan anle jing, composed by Jingjing (fl. late 8th to early 9th century) under the Tang dynasty. Focusing on the contact between Jingjing and his contemporary Prajña (fl. late 8th to early 9th century), a Buddhist translator, it compares the Zhixuan anle jing and Prajña’s Dasheng bensheng xindi guan jing in terms of their shared imagery, suggesting that Jingjing’s text may have been composed after the production of the Dasheng bensheng xindi guan jing in 811 CE, yet before the suppression of Buddhism started in 843. This article also provides a transcription of the Zhixuan anle jing based on photographs of the manuscripts and the author’s punctuated version. In this way, it offers a new understanding of Jingjing’s obscure life and his contact with Buddhism.

本文考察了唐代京京（约八世纪末至九世纪初）所著的经教文本《知玄安乐经》。重点关注晶晶与同时代佛教翻译家般若（ 8世纪末9世纪初）之间的接触，将《智选安乐经》与般若的《大生本生心地观经》的共同意象进行比较，表明晶晶的文本可能是在公元 811 年《大圣本圣新地观经》问世之后，但在 843 年镇压佛教之前。本文还提供了《至玄安乐经》的抄本基于手稿的照片和作者的标点版本。从而让人们对晶晶默默无闻的一生以及他与佛教的接触有了新的认识。
