Seng-zhao cited, in his writing "Chuyuimakitsukyo (Vimalak?rti Sutra commentary)," the idea of "Honmatsu," which had been referred to by Wang Bi of Wei, and other scholars replaced the word "所以迹" with "本" (hon) and defined it (hon) as an unfathomable nirvana (enlightenment) achieved by Bodhisattva and "迹" (jaku) as a means to enlighten people, as used by Bodhisattva.
僧肇は『注維摩詰経』で、魏の王弼（おうひつ）などが用いた“本末”の思想を引用し、“所以迹”を“本”と言い換えて、“本”を菩薩の不可思議なる解脱（悟りの内容）とし、“迹”を菩薩が衆生を教化するために示現した方便という意味で使用した。
