Míngdé 明得 (sobriquets Yuè-tíng 月亭 “Moon-Pavilion” and Qiān-sōng 千松 “Thousand-Pines”; DILA Authority A008323; 1531 – 13 February 1588) was a Ming-period Tiāntái 天台 monk and exegete. Lay surname Zhōu 周; native of Wū-chéng 烏程 (modern Húzhōu, Zhèjiāng). He took the tonsure at thirteen at the Cí-shàn-ān 慈善菴 in the Shuāng-lín 雙林 district under the master Zhēn-xiáng 真祥, and studied first the Yogic-Tantric (yújiā 瑜珈) tradition. After unsuccessful study under Bǎi-chuān Hǎi 百川海, he became the dharma-heir (法嗣) of Wàn-sōng Huì-lín 萬松慧林 (1482–1557; whence his second sobriquet Qiān-sōng), who instructed him in the Śūraṅgama-sūtra. The decisive moment of his awakening, according to the Míng gāosēng zhuàn (T2062), came when he reached the line “the original nature being pure, how do mountains, rivers and the great earth suddenly arise?” (清淨本然云何忽生山河大地).
He spent three years in solitary retreat on the Líng-xiāo Peak 凌霄峰 of Mt. Jīngshān 徑山, then moved to the Chuán-yī-ān 傳衣菴 there, where he lectured on the Śūraṅgama. Subsequently he taught at the Líng-yǐn-sì 靈隱寺, presided over the Yuán-zhèng-sì 圓證寺, and was invited by Lù-gōng of Wǔtái 五臺陸公 to lecture on the Avataṃsaka at the Dōng-chán-sì 東禪寺 in Xiùshuǐ 秀水 (Jiāxīng). He died at fifty-eight in the first month of Wàn-lì 16 (= 17 January 1588 lunar / 13 February 1588 Gregorian); his stūpa is at Mt. Jīngshān.
Within the Kanripo corpus he is represented by the four ancillary Tiāntái treatises on the Suvarṇaprabhāsa in Xuzangjing Vol. 20: the Jīn-guāngmíng jīng xuán-yì kē 金光明經玄義科 (KR6i0310) and Jīn-guāngmíng jīng wén-jù kē 金光明經文句科 (KR6i0312) — outline tables of contents — and the two huì-běn 會本 collations Jīn-guāngmíng jīng xuán-yì shíyí jì huì-běn (KR6i0311) and Jīn-guāngmíng jīng wén-jù wén-jù-jì huì-běn (KR6i0313). His disciples include Zhēn-jiè 真界 and Zhēn-jué 真覺.
