2.9

舍利弗。於汝意云何。彼佛何故號阿彌陀。舍利弗。彼佛光明無量。照十方國。無所障礙。是故號為阿彌陀。又舍利弗。彼佛壽命。及其人民。無量無邊阿僧祇劫。故名阿彌陀。舍利弗。阿彌陀佛成佛已來。於今十劫。又舍利弗。彼佛有無量無邊聲聞弟子。皆阿羅漢。非是算數之所能知。諸菩薩亦如是舍利弗。彼佛國土。成就如是功德莊嚴。

"Śāriputra, what do you think? For what reason is that Buddha named Amitābha? Śāriputra, that Buddha's light is immeasurable, illuminating the lands of the ten directions without any obstruction; therefore he is named Amitābha. Moreover, Śāriputra, the lifespan of that Buddha and his people lasts for immeasurable and boundless asaṃkhyeya-kalpas; therefore he is named Amitābha. Śāriputra, since Amitābha Buddha attained buddhahood, it has now been ten kalpas. Moreover, Śāriputra, that Buddha has immeasurable and boundless śrāvaka disciples, all of whom are arhats, beyond the ability of calculation to know; and so it is with the bodhisattvas. Śāriputra, that Buddha-land is accomplished with such virtues and adornments as these.
