佛說觀佛三昧海經 7.13

7.13

「爾時世尊！放項金光化作一萬八千諸大化佛，一一化佛復放光明，如此項光亦復化作一萬八千諸大化佛，佛佛相次滿虛空中，如鴈王翔往至彼國，始到國界王出奉迎為佛作禮。

"At that time, the Bhagavat emitted golden light from his nape, which transformed into eighteen thousand great transformation Buddhas. Each transformation Buddha in turn emitted light, and this light from their napes likewise transformed into eighteen thousand great transformation Buddhas. Buddha following upon Buddha, they filled the open sky, soaring like king geese as they proceeded to that kingdom. Just as he reached the border of the realm, the king came out to receive him and paid homage to the Buddha.
