法華義疏 7.29

7.29

界外受生。如《釋論》及《勝鬘經》皆云羅漢三界外受反易生，直往十信菩薩則在界內受生。

They are reborn outside the realms. As the Commentary (Mahāprajñāpāramitopadeśa) and the Śrīmālādevī Sūtra both state, arhats undergo transformation-birth outside the three realms, whereas direct-advancing bodhisattvas of the ten faiths are reborn inside the realms.
