Kyō’i 恭畏 — Early-Edo Japanese Shingon scholar-monk of the Daigo Sanbō-in 醍醐三寶院 lineage, active in the Kan’ei era (1624–1644). His monastic sobriquet Kongōshō 金剛生 (“Vajra-Begotten”) appears in the colophon of his sole surviving work in the Taishō, the Gisho-ron 僞書論 (KR6t0215, T78n2509), which he composed and transmitted to his disciple Gyōshin 堯辰 on Kan’ei 6 (1629), 9th month, auspicious day.
The Gisho-ron is a thirteen-article polemic identifying spurious works (僞書) within the Shingon transmission, exposing pseudepigraphic colophons and fabricated lineages — among them the Sanchi-shū 三旰集, Hōshittadaranikyō 寶悉陀羅尼經, Sansenji 三千事, Honji-ge 本地偈, the Rokugatsu-shō 六月抄, the Bekki 別記 (also called Eiryaku-shō 永暦抄), the Sekishitsu 石室, the Tōji ichi-chōja hōmu clause, and various manuscripts ascribed to Kenshin 憲深, Jōken 成賢, and others. His method is text-critical and forensic: comparing dates, titles, and lineage-records against the established Daigo-ji kechi-myaku 嫡嫡相承血脈 (定海→實運→勝賢→成賢), and exposing chronological impossibilities (e.g., Kenshin would have been six years old at the date of a colophon allegedly composed by him in Kenkyū 8 = 1197).
He explicitly identifies his polemic as a defense against bōryū 傍流 (collateral) lineages — those without the legitimate Daigo Sanbō-in kechi-myaku — who mistake spurious works for authentic transmissions.
