仁王護國般若經疏 4.13

4.13

問：界外實無眾生耶？答：聖教不同，有無異說。此經則云界外無眾生，餘經則有。《法華》云「餘國作佛，三百由旬外權置化城。」《淨名》云「上方界分度如四十二恒佛土，有佛名香積。」若界外無人，豈容三界內上方更有爾許佛土耶？故知亦有。

Question: Are there truly no sentient beings outside the realms? Answer: The sacred teachings differ, with diverging accounts of existence and nonexistence. This sūtra says that outside the realms there are no sentient beings, while other sūtras say there are. The Lotus Sūtra says: "Achieving buddhahood in other lands, three hundred yojanas away, provisionally establishing a conjured city." The Vimalakīrti Sūtra says: "In the upper regions, across as many buddha-lands as forty-two Ganges sands, there is a buddha named Fragrance Accumulated (Gandhahastin)." If outside the realms there were no persons, how could there possibly be so many buddha-lands further in the upper regions within the three realms? Therefore we know that they also exist.
