「『眾寶國土一一界上有五百億寶樓閣。』」眾寶國者，總召彼土也。一一界者，準《小本》即池岸上，經云「四邊階道上有樓閣」等。二、諸天作樂。

"‘In each region of this land of many jewels, there are fifty billion jeweled multi-storied pavilions.’" "Land of many jewels" is a comprehensive reference to that realm. "Each region," according to the Smaller Sūtra, refers to the banks of the ponds; the sūtra states: "Above the stepped pathways on the four sides are multi-storied pavilions," and so forth. Second, the devas making music.
