Qīnguāng 親光 (Skt. Bandhuprabha, “Kindred-of-Light”; conventionally fl. mid-seventh century, circa 580–670 CE), Indian Yogācāra master, contemporary of 玄奘 Xuánzàng at Nālandā. The transliterated form 般徒鉢羅婆 (Bāntúbōluōpó) is occasionally encountered. Bandhuprabha was a senior member of the Yogācāra teaching circle at Nālandā in the period of Xuánzàng’s residence and is conventionally identified as the principal author of the KR6i0589 Buddhabhūmi-vyākhyāna (Fódì jīng lùn 佛地經論, T26 no. 1530) — though Xuánzàng’s signature line Qīnguāng púsà děng zào 親光菩薩等造 (“composed by Bandhuprabha and others”) indicates a multi-authored upadeśa compilation rather than a single-author work.
His other identifications in the Yogācāra-doctrinal record are less secure; he is sometimes connected to the Buddhabhūmi-pañcaka (the closely related Yogācāra five-cognitions doctrine) as developed by Sthiramati and others, but the textual evidence is fragmentary. The Sanskrit name is preserved in inscriptional Sanskrit material from the Pāla-period Nālandā corpus. The DILA Buddhist Person Authority is A002089 (Bandhuprabha). Lifedates uncertain; the conventional bracket circa 580–670 reflects his evident contemporaneity with Xuánzàng’s mid-seventh-century Nālandā residence.
Works in the Kanripo corpus: KR6i0589 Fódì jīng lùn (T26 n1530, in Xuánzàng’s translation, 649 CE).
