法華經義記 8.15

8.15

「是菩薩眾中有四導師」下，正開發敘中本有二，從此下是第二明踊出菩薩與佛問答有四，即成四段，可解也。

"In this assembly of bodhisattvas there were four leaders" down: originally there were two within the direct narrative of emergence; from here down is the second, clarifying that there are four questions and answers between the springing-up bodhisattvas and the Buddha, which form four sections and can be understood.
