10.24

第四辨出現中文分有三，初明一世界中或有多劫無佛或有一劫有多佛出，二彼彼已下明十方世界有無量佛，第三決定無有一佛土中下明一世界中無二佛出意。

Fourth, in distinguishing manifestation, the text is divided into three: first, it explains that within one world-realm there may be many kalpas without a Buddha, or within one kalpa there may be many Buddhas appearing; second, from 'in those respective [directions]' onward, it explains that in the world-realms of the ten directions there are immeasurable Buddhas; third, from 'it is definitive that in no single Buddha-land' onward, it explains the intent behind there not being two Buddhas appearing in one world-realm.
