妙法蓮華經玄義 4.138

4.138

一、隨信行位者，是鈍根人，入見道之名也。非自智力，憑他生解。是人在方便道，先雖有信，以未習真，信不名行。行以進趣為義。從得苦忍真明，十五剎那進趣見真，故名隨信行位也。

1. The stage of follower by faith is the designation for a person of dull faculties who enters the path of seeing. Not relying on their own intellectual power, they produce understanding through another. When this person was on the path of expedient means, although they had faith beforehand, because they had not yet practiced the real, faith was not called practice. Practice has the meaning of progressing forward. From attaining the true radiance of patience regarding suffering, progressing for fifteen kṣaṇas to see the real, this is called the stage of follower by faith.
