Late-Táng (Tiānbǎo / Dà-lì-era) Buddhist scholar-monk of the Jīng Xīmíng dàochǎng 京西明道場 (the Xīmíngsì 西明寺 in Chángān, the major imperial Buddhist monastic centre). DILA-recorded placeOfOrigin: Jiànkāngjūn 建康軍 (modern Jiāngníng / Nánjīng region). Lifedates unrecorded; active in the late-Táng / mid-Táng decades. Important Yogācāra scholar known for two surviving works recovered from Dūnhuáng: a Vajracchedikā sub-commentary, Jīngāng bānruò jīng zhǐzàn 金剛般若經旨贊 (2 juan, KR6c0107, T85 no. 2735); and the Dàshèng bǎifǎ míngmén lùn shūjì 大乘百法明門論疏記 (Yogācāra). Tánkuàng’s work is one of the more substantial late-Táng Vajracchedikā commentaries to survive only via the Dūnhuáng cache rather than through canonical transmission, and is doctrinally aligned with the Xīmíngsì Yogācāra school descending through Yuáncè 圓測.
