佛說觀佛三昧海經 4.44

4.44

"Hundreds of millions of rays shine toward the southwest, reaching as far as immeasurable worlds in the southwest. Having reached those worlds, their rays fall like rain, resembling multi-colored jewels. From each jewel emerge tens of billions of rays; each ray combines to form a jeweled terrace; at each corner of the terraces are twelve Mount Sumerus; within each Mount Sumeru are immeasurable niche-shrines; in each niche are immeasurable transformation Buddhas; and each transformation Buddha has immeasurable bodhisattvas as their retinue. These multitudes of transformation Buddhas and transformation bodhisattvas also praise and preach the teachings on the ten wholesome deeds. Practicing such contemplation is called right contemplation. If one contemplates otherwise, it is called wrong contemplation."
