Zōngjiān 宗堅 (仝 “together”)
Mid-seventeenth-century Línjì Chán monk, dharma-heir of Sōngshān Yězhú Fúhuì 嵩山野竹福慧 in the Pòshān / Yuánliáo / Shānhuī / Fúhuì Yúnnán mission sub-line. Co-editor (with 宗上 Zōngshàng) of KR6q0438 《嵩山野竹禪師錄》 (Jiāxīng Canon J29 B224).
The 仝 character in “宗堅仝” in the catalog-meta is a Chinese “together / same” marker (= 同) indicating “Zōngjiān together [with]” — i.e., the co-editor tag rather than part of the fǎhuì. The name proper is Zōngjiān 宗堅.
Native place, lay surname, and lifedates unrecovered.
