Péi Xiū was a serious lay Buddhist practitioner: refused wine and meat as householder, composed numerous Buddhist writings, and sponsored the construction of the Mìyìn sì 密印寺 as a memorial to Guīshān Língyòu 溈山靈祐 (whose chief lay patron Péi was; see KR6q0075). His principal dharma-masters were the Chán master Huángbò Xīyùn 黃檗希運 (d. 850), of the Hóngzhōu 洪州 school, and the Huáyán/Chán-syncretist scholar Guīfēng Zōngmì 圭峯宗密 (780–841).
Works in the Kanripo corpus (as compiler / jí 集): KR6q0087 Huángbò shān Duànjì chánshī chuánxīn fǎyào 黃檗山斷際禪師傳心法要 (1 juan, T48 n2012A) and KR6q0088 Wǎnlíng lù 宛陵錄 (T48 n2012B) — compiled from his two periods of direct instruction under Xīyùn at Hóngzhōu’s Lóngxīng sì 龍興寺 (Huìchāng 2 = 842) and Xuānzhōu’s Kāiyuán sì 開元寺 (Dàzhōng 2 = 848), finalised in Dàzhōng 11 (857). Also separately authored the preface to Zōngmì’s Yuánjuè jīng commentary and the influential preface Chányuán zhūquánjí dūxù 禪源諸詮集都序.
Dates: Catalog-vs-external discrepancy. DILA A003624 gives 797–870, following the Fózǔ lìdài tōngzǎi (T49 n2036): “Xiántōng 11 zǎixiàng Péi Xiū hōng … hōng nián qīshí yǒu sì” (died Xiántōng 11 = 870, aged 74). CBDB 31999 gives 791–864, following the Xīn Tángshū / Jiù Tángshū (juan 182 / juan 177) Tang-history tradition. CBDB’s figure is the more externally-verified and is followed here; the Buddhist-chronicle 870 death-date represents a late corruption of the primary Tang-history record.
