法華文句記 9.197

9.197

故知本地三身，即諸經諸身之喉，如衣之襟、諸根之目，如屐之蒵。「蒵」字從草，出《風俗通》。故知今明本迹，不與諸經諸師同也。

Therefore, we know that the three bodies of the ground of origin are the throat of all bodies in all sūtras, like the collar of a robe, the eyes of the sense faculties, or the thong of a sandal. The character 'xi' (蒵) takes the grass radical and appears in the Fengsu Tong. Therefore, we know that the present clarification of origin and traces is not the same as that of other sūtras and other masters.
