Because "Ikuo-roku" describes, 'The monk asked why Daigen bosatsu was putting his hand against the bridge of his nose, and the master answered that 行船全在樞梢人,' temples of the Soto sect enshrine the guardian god of temple gates referred to as Shoho Shichiro as "Shoho Shichiro Daigen shuri bosatsu," deeming him to be the same god as or earthly manifestation of him, based on the theory of Honji suijaku (Shinto and Buddhist syncretism).
『育王録』に「僧問。大権菩薩因甚以手加頞。師云。行船全在樞梢人」とあることから、曹洞宗の寺院が招宝七郎と称して山門守護の神とするものをこれを同体、あるいは本地垂迹と見たてて、招宝七郎大権修理菩薩として祀る。
