Ān-huì 安慧 (Skt. Sthiramati “Fixed Wisdom”; also transcribed 悉地羅末底 Xī-dì-luó-mò-dǐ; also written 安惠; DILA A000371; c. late 5th–early 6th century CE) was an Indian Yogācāra philosopher of the post-Vasubandhu generation, active in Valabhī (伐臘毗國) in western India. The Chéngyùshí lùn shùjì 成唯識論述記 (by 窺基) records that Sthiramati was a student of Guṇamati 德慧 and a predecessor of 護法 (Dharmapāla, 530–561 CE). He is listed among the ten major commentators on Vasubandhu’s Triṃśikā (《唯識三十頌》) in the Chinese Yogācāra tradition.
His principal works include a commentary on the Triṃśikā (《唯識三十頌釋論》), commentaries on various Vasubandhu Yogācāra treatises, and the Abhidharmakośa-ṭīkā-tattvārtha, a commentary on Vasubandhu’s Abhidharmakośa preserved in Chinese as 俱舍論實義疏 (KR6l0030, T1561) and in Tibetan in the Tengyur (Tōhoku 4122). Works in the Kanripo corpus: KR6l0030 俱舍論實義疏 (T1561) and KR6v0008 Ēpídámó jùshèlùn shíyì shū 阿毗達磨俱舍論實義疏 — the complete fascicle-three Beijing-Library Dūnhuáng witness recovered in 1995, supplementing the Pelliot-derived T1561 excerpt.
