佛說佛名經 19.11

19.11

佛告舍利弗：「復有人過彼若干微塵分佛國土為一步，如是速疾神通，行東方世界無量無邊劫下一微塵，東方盡如是微塵。若著微塵及不著者，下至水際上至有頂滿中微塵。如是南方乃至十方，下至水際上至有頂滿中微塵。舍利弗！於意云何？彼微塵可知數不？」

The Buddha said to Śāriputra: “Suppose there were another person who traversed as many Buddha-lands as those parts of subtle particles of dust in a single step, and with such swift supernatural power traveled through the worlds of the eastern direction, depositing one subtle particle of dust after immeasurable and boundless kalpas, until all such subtle particles of dust were exhausted in the eastern direction. Whether holding a subtle particle of dust or not, from down at the water boundary up to the Summit of Existence, it was entirely filled with subtle particles of dust. In the same way, from the southern direction throughout the ten directions, down to the water boundary and up to the Summit of Existence, it was entirely filled with subtle particles of dust. Śāriputra, what do you think? Could those subtle particles of dust be known in number?”
