Wùyuán 悟元 (Yīchū Wùyuán 一初悟元)
Mid-seventeenth-century Cáodòng 曹洞 Chán master of the 悟-generation, dharma-heir of Yuānhú Miàoyòng 鴛湖妙用 (1587–1642). Hào Yīchū 一初. One of three named dharma-heirs of Miàoyòng (with Yúnfēng Jūn 雲峰鈞 and Jièān Wùjìn 介菴悟進).
Mentioned throughout KR6q0416 juan 1 jīyuán 機緣 section as the master’s close attendant and interview-partner — several crucial gōngàn exchanges preserve Wùyuán’s name: “shī yī rì huàn Yīchū rù fāngzhàng … 師一日喚一初入方丈” (“one day the master summoned Yīchū into the abbot’s quarters”), including the “cāngtiān cāngtiān 蒼天蒼天” / “pāi xī yī xià biàn chū 拍膝一下便出” exchange, and the separate “jǔ quán … shī yì zhǎng 舉拳 … 師亦掌” exchange. Received the farewell transmission-verse “yán liú yī duàn shì, jìng wú tóu yǔ wěi, fù yǔ shī-zi-ér, xiàohǒu mǎn dàdì 沿流一段事竟無頭與尾付與師子兒哮吼滿大地” along with the co-heirs Yúnfēng Jūn and Jièān Wùjìn. Co-compiled the present yǔlù with Wùjìn.
Jointly with Wùjìn, carried Miàoyòng’s relics thousands of lǐ across war-torn Jiānán after the MíngQīng transition to return them to the Jiāxīng Xīngshànsì 興善寺 (Miàoyòng’s original tonsure temple) for final burial — an act of substantial filial-institutional service in the chaotic 1640s.
Native place, lay surname, and lifedates unrecovered.
