宋高僧傳 4.9

4.9

釋普光，未知何許人也。明敏為性，爰擇其木，請事三藏奘師。勤恪之心，同列靡及。至於智解，可譬循環，聞少證多，奘師默許。末參傳譯，頭角特高左右，三藏之美，光有功焉。初，奘嫌古翻《俱舍》，義多缺然，躬得梵本再譯真文，乃密授光，多是記憶西印薩婆多師口義。光因著疏解判。一云其疏至圓暉略之為十卷，如漢之有沲歟？又甞隨奘往玉華宮譯《大般若經》，厥功出乎裨贊也，時號大乘光。觀夫奘自貞觀十九年創譯，記麟德元年，終于玉華宮，凡二十載，總出大小乘經律論七十五部一千三百三十五卷，十分七八是光筆受，或謂嘉光、普光也。若驗從辯機同參譯務，即普光是也。

Shi Puguang—it is unknown where he was from. He was bright and perceptive by nature; selecting his roost, he requested to serve Tripiṭaka Master Xuanzang. In his diligence and reverence, none of his peers could match him. As for his intellectual comprehension, it could be likened to an endless ring: he heard little yet realized much, which Master Xuanzang tacitly approved. Later he took part in the translation work, standing out head and shoulders above those around him; for the Tripiṭaka Master's excellence, Puguang truly contributed merit. Earlier, Xuanzang disliked the older translations of the Abhidharmakośa for their many deficiencies in meaning, and having personally obtained the Sanskrit text, he retranslated the authentic words. He then secretly transmitted them to Puguang, mostly consisting of his recollection of the oral explanations of Sarvāstivāda masters of Western India. Puguang consequently composed a commentary to explain and analyze them. One account says that his commentary was later abridged by Yuanhui into ten fascicles, just like the Han River branching into the Tuo. He also once accompanied Xuanzang to Yuhua Palace to translate the Mahāprajñāpāramitā Sūtra, where his contribution lay in assisting and supporting; he was called "Mahāyāna Guang" at the time. Consider that from the nineteenth year of the Zhenguan era when he began translating until the first year of the Linde era when he passed away at Yuhua Palace, Xuanzang produced over twenty years seventy-five works of Mahāyāna and Hīnayāna sūtras, vinaya, and śāstras in one thousand three hundred and thirty-five fascicles; seven or eight tenths of these were transcribed by Guang's brush, who was variously called Jiaguang or Puguang. If one checks who participated in the translation work alongside Bianji, it was indeed Puguang.
