佛說觀佛三昧海經 3.16

3.16

「二光上照無量世界，一一光間有一光臺，其色眾妙不可具名；一一光臺龕室無數；一一龕中，無量化佛結加趺坐，聲聞菩薩一切大眾，皆悉圍繞。過於上方無量世界，化為一佛，佛身高顯如須彌山，如是諸佛其數無量，皆出舌相亦復如是！

"Two rays of light shine upward on immeasurable worlds. Between each ray of light is a platform of light whose various marvellous colours cannot be fully described. Each platform of light has countless niches; in each niche, immeasurable transformation Buddhas sit cross-legged, completely surrounded by voice-hearers, bodhisattvas, and the entire assembly. Traversing immeasurable worlds above, they transform into a single Buddha whose body is tall and eminent like Mount Sumeru. The number of such Buddhas is immeasurable; they all extend the mark of their tongues in the same way!
