31.17

新菩薩藏經。諸佛成就不思議智故。能行知諸風雨相。知世有火風。名烏盧博迦。眾生諸有覺受。皆由此風之所動搖。此風輪量高三拘盧舍（拘盧舍。此云一鼓聲問。準雜寶藏經。五里為一拘盧舍。毘曇論。八拘盧舍為一由旬。即智論中品由旬。當四十里也）於此風上虛空之中。復有風起。名贍薄迦。此風輪量高十由旬（云云）。如是次第輪上六萬八千拘胝風輪之相。悉能了知。最上風輪名周遍上界。為水輪之所依止。其水量高六十八百千由旬。為大地之所依止。其地量高六十八千由旬。是地量表。有一三千大千世界。

The New Bodhisattvapiṭaka-sūtra [says]: 'Because the buddhas have accomplished inconceivable gnosis, they are able in their course to know all the characteristics of wind and rain. They know that in the world there is a fiery wind named *Urubhaga [?]. All sensations and feelings of sentient beings are stirred by this wind. The height of this wind disc is three krośas. (A krośa is translated here as the hearing distance of a drum beat. According to the Za baozang jing, five li make one krośa. The Abhidharma treatises state that eight krośas make one yojana, which corresponds to the medium-grade yojana in the Dazhidu lun, equivalent to forty li.) In the empty space above this wind, another wind arises, named *Jambaka [?]. The height of this wind disc is ten yojanas (and so forth).' In this manner, one can fully know in succession the characteristics of the sixty-eight thousand koṭi wind discs above the discs. The uppermost wind disc is named Universally Pervading the Upper Realm, which serves as the support for the water disc. The height of that water is sixty-eight hundred thousand [i.e., 6,800,000] yojanas, which serves as the support for the great earth. The height of that earth is sixty-eight thousand [i.e., 68,000] yojanas. On the surface of this earth is one great trichiliocosm.
