Tōnglǐ Dàshī Héngcè 通理大師恒策 (1049–1098), zì Yìnghǎi 應海, was a senior monk of the Yúnjū sì 雲居寺 on Fángshān 房山 (south-west of present-day Beijing) and the principal director of the late-eleventh-century phase of the Fángshān stone-sūtra engraving project under Liáo Dàozōng 道宗 (r. 1055–1101). His lifedates and major biographical data are preserved in Fángshān-stone inscriptions, especially the Liáo Yúnjūsì xù mìzàng shíjīng tǎjì 遼雲居寺續祕藏石經塔記 (1117), which records that under his supervision more than 4,000 stone slabs were engraved with scripture and devotional liturgies, and that the engraved canon-stones were stored in a newly excavated cave on the Fángshān ridge sealed shortly after his death. He compiled and edited several short devotional and liturgical pieces that are preserved among the Fángshān-canon stones, including the Jīngāng lǐ yī běn 金剛禮一本 (KR6i0552; F12 no. 546).
He is to be carefully distinguished from the Qīng-dynasty Huáyán scholar-monk 通理 Dátiān Tōnglǐ 達天通理 (1701–1782), with whom he shares the fǎhào “Tōnglǐ” but otherwise nothing.
