Northern–Southern-Sòng-period Buddhist scholar-monk, granted the imperial honorific Guāngyán Wújì dàshī 光嚴無際大師 (“Wújì, Master of Splendid Adornment”) and styled in the bibliographic catalogues simply Wújì 無際 (“the Boundless”). Biographical details and lifedates not preserved; the floruit given here (c. 1100–1180) reflects the late-Northern-Sòng / early-Southern-Sòng commentarial environment in which his attested works were composed.
普觀’s principal surviving work is the Lánpén jīng shū huìgǔ tōngjīn jì 蘭盆經疏會古通今記 (X373) — a sub-commentary on Yúlánpén jīng shū 盂蘭盆經疏 (T1792) by 宗密. The preface to that work characterizes the project as a critical synthesis (“會古通今” — “harmonising the ancient and penetrating the present”) of the prior sub-commentary tradition: the Yányìnjì of Bìbǎo Zhīhán 碧寶尊者 (the so-called “Stone-wall School”, 石壁), the Xīnchāo 新鈔 of Gūshān Zhìyuán 孤山智圓 (964–1027), and 元照’s contemporaneous Xīnjì 新記 (X372). The work’s preface remarks that it tries to reconcile what 普觀 sees as the exegetical excesses of all three preceding sub-commentaries.
