法華玄論 9.114

9.114

答：前云化二乘名釋迦、化菩薩名舍那者，此一義耳。又雜化三乘為釋迦，純化菩薩名舍那，故無過也。

Answer: What was said earlier—that converting the two vehicles is named Śākyamuni, and converting bodhisattvas is named Rocana—is just one aspect. Furthermore, converting the three vehicles in a mixed manner is Śākyamuni, while converting bodhisattvas purely is named Rocana; therefore there is no fault.
