大方便佛報恩經 1.34

1.34

時，娑婆世界即變清淨，無諸山藪、大小諸山、江河池湖、溪㵎溝壑。其中眾生尋光見佛，歡喜合掌，頭頂禮敬，心生戀慕，目不暫捨。爾時世尊即攝光明，遶身七匝，還從頂入。尊者阿難觀察眾心，亦咸皆有疑。欲顯發如來方便密行故，并欲為未來一切眾生開其慧眼故；欲令一切眾生渡渴愛海，得至彼岸，永得安樂故；欲令眾生念識父母師長重恩故，即從座起，整衣服，偏袒右肩，胡跪合掌，而白佛言：「世尊！阿難事佛已來，未曾見佛笑。笑必有意。願佛示之，願佛說之，斷除如是大眾疑網。」

At that time, the Sahā world was immediately transformed and became pure, free of marshes, mountains great and small, rivers, ponds, lakes, streams, ravines, and gullies. The sentient beings therein, following the light, saw the Buddha; rejoicing, they joined their palms, bowed their heads in homage, and conceived deep affection and yearning, not turning their eyes away even for a moment. At that time, the Bhagavat gathered in the radiance; it circled his body seven times and returned to enter the crown of his head. The Venerable Ānanda, observing the minds of the assembly, saw that they all harbored doubts. Wishing to reveal the Tathāgata's secret practices of upāya, and also wishing to open the eye of wisdom for all future sentient beings; wishing to cause all sentient beings to cross the ocean of thirsting craving, reach the other shore, and attain eternal peace and joy; and wishing to cause sentient beings to be mindful of and recognize the weighty kindness of their parents, teachers, and elders, he immediately arose from his seat, straightened his robes, bared his right shoulder, knelt with both knees on the ground, joined his palms, and said to the Buddha: "Bhagavat! Ever since Ānanda served the Buddha, he has never seen the Buddha smile. A smile must have a purpose. May the Buddha show it, may the Buddha explain it, and resolve the web of doubts of this great assembly!"
