法華義疏 7.217

7.217

上已通之。又迦葉善吉異口同音，迦葉說偈即善吉說也。又《智度論》云「《波若》有二種：一、獨為菩薩說；二、三乘共說」。《大品》則是共說，迦葉雖復無言，而猶是善吉類，故得言迦葉說。

This was already resolved above. Furthermore, Kāśyapa and Shanji spoke with one voice through different mouths; Kāśyapa speaking the verses is precisely Shanji speaking them. Moreover, the Dazhidulun states: "Prajñā has two kinds: first, taught solely for bodhisattvas; second, taught in common for the three vehicles." The Pañcaviṃśatisāhasrikā Prajñāpāramitā Sūtra is indeed the common teaching. Although Kāśyapa did not speak, he still belonged to the same class as Shanji; thus it can be said that Kāśyapa spoke.
