佛說觀佛三昧海經 9.31

9.31

爾時世尊放常光明照尼拘樓陀精舍及十方國，皆作金色，佛神力故令金色地分為二分，一一分中五百億佛，從下方界皆自踊出住立空中，合掌讚歎彌勒菩薩摩訶薩言：「善哉佛子！乃能憐愍未來眾生生末法者，勸請世尊說觀像相。」時諸化佛說此語已，踊身虛空作十八變。釋迦文佛即自微笑，笑時口中生大蓮華，其華有光如合百億日月星宿，眾宿月間百億化佛，結加趺坐坐師子床。

At that time, the Bhagavat emitted his constant light, illuminating the Nyagrodhārāma and the lands of the ten directions, turning them all golden. Through the Buddha's supernatural power, the golden ground was made to divide into two sections. In each section, fifty billion Buddhas all leaped forth on their own from the realms below and stood in the sky. Joining their palms, they praised the bodhisattva mahāsattva Maitreya, saying: "Excellent, Son of the Buddha! You are truly able to pity the sentient beings of the future who will be born in the Latter Dharma, and to request the Bhagavat to explain the characteristics of contemplating the image." After those transformation Buddhas had spoken these words, they leaped into the sky and performed the eighteen transformations. Śākyamuni Buddha then smiled. When he smiled, a great lotus flower was produced from his mouth, whose light was like the combination of ten billion suns, moons, stars, and lunar mansions. Between the lunar mansions and moons were ten billion transformation Buddhas, seated cross-legged on lion thrones.
