Sēngqié 僧伽 (628–710), known as Sìzhōu Dàshèng 泗州大聖 (“Great Sage of Sìzhōu”) and Zhèngshèng Dàshī 證聖大師, was a Central Asian (Hé 何 / Sogdian, by the Sòng gāosēng zhuàn) monk who arrived in China in the Lóngshuò era (661–663) and settled at Línhuái 臨淮 in Sìzhōu (modern Xūyí 盱眙, Jiāngsū), where he founded the Pǔguāng wáng sì 普光王寺. He gained imperial patronage under Zhōngzōng 中宗, who summoned him to Cháng’ān in 708 and built the Jiànfú sì 薦福寺 cloister for him. He died in 710 and was given the posthumous title Pǔzhào míngjué dàshī 普照明覺大師 in 712 by Ruìzōng 睿宗. From the late Tang onward he was identified as a manifestation (huàshēn 化身) of Avalokiteśvara 觀音 / Guānyīn, with a flourishing cult centred on his stūpa at Sìzhōu and on his portable image; his miraculous biographies are preserved in Sòng gāosēng zhuàn 18 (T2061), Fózǔ tǒngjì (T2035), and Shénsēng zhuàn (T2064). In the apocryphal KR6u0057 Sēngqié héshàng yù rù nièpán shuō liù dù jīng 僧伽和尚欲入涅槃說六度經 his teaching is framed as a parinirvāṇa-discourse delivered before retiring to a “transformation citadel” (huàchéng 化城) east of the sea, prophesying the survival of devotees who keep the six rules.
