Early-Yuán nèidān 內丹 author from Mǐn 閩 (Fújiàn 福建), zì Shénfèng 神鳳, hào Xuáncháozǐ 玄巢子 (Master of the Mysterious Nest); his preface signs himself “Wǔfú Xuáncháozǐ Lín Yuán Shénfèng” 五福玄巢子林轅神鳳, suggesting he hailed from Wǔfú 五福 (location unidentified, in Fújiàn). Author of [[KR5a0253|Gǔshén piān 谷神篇]] (DZ 252), a two-juan popular treatise on inner alchemy, preface dated Dàdé 大德 jiǎchén 甲辰 (1304), printed by his patron Zhào Sīxuán 趙思玄 (zì Cóngshàn 從善, hào Sīxuán 思玄) of Línchuān 臨川 in 1315. Lín Yuán traces his line back to Hán Xiāoyáo 韓逍遙 (known through a quotation from his Nèizhǐ tōngxuán bìjué 內指通玄祕訣 in [[KR5c1005|DZ 1005 Zhōuyì cāntóng qì fāhuī]] 1.11b) and identifies his immediate teacher as a certain Yùzǐ Lǘ’ān 玉子閭菴, a disciple of Lúán Yùjūn 蘆菴郁君. The Gǔshén piān mixes nèidān discourse with references to liturgical Daoism — the Běidǒu jīng 北斗經, Hùnyuán fúshuǐ 混元符水 — and shows no Quánzhēn affiliation. No CBDB record found; lifedates not recoverable.
