法華義疏 8.298

8.298

「諸比丘」下，第二、明能化得益。所以明能化得益者，為擊下根人也。明我聞《法華》遂進成佛，汝聞《法華》云何乃退作聲聞，一何可愍耶？

From "Monks" onwards is the second [part], explaining that those capable of transforming obtained benefit. Why is it explained that those capable of transforming obtained benefit? It is to spur on persons of dull faculties. It clarifies: "I heard the Lotus Sūtra and thereupon advanced to become a buddha; how is it that you heard the Lotus Sūtra and yet regressed to become śrāvakas? How truly pitiable!"
