佛說觀佛三昧海經 4.44

4.44

「億億光照西南方，乃至西南方無量世界，至彼界已其光如雨，似雜色珠，一一珠中出百億光；一一光合成寶臺；一一臺角有十二須彌山；一一須彌山龕室無量；一一龕中有無量化佛；一一化佛有無量菩薩以為眷屬，是眾化佛及化菩薩，亦皆讚歎說十善法。如是觀者名為正觀，若異觀者名為邪觀。」

"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."
