佛說觀佛三昧海經 8.14

8.14

「佛勅阿難：『汝告波斯匿王及諸比丘，各自遊戲。』波斯匿王白諸大德：『如來大慈欲化婬女，我等今者宜各遠去。』作是語已却行而退，唯此千二百五十比丘侍立佛後。佛告憍陳如：『將汝徒眾經行林中。』五百比丘大智舍利弗為眾上首，猶故合掌侍佛左右。佛告舍利弗：『汝亦隨意與諸論師論講所宜。』五百比丘隨舍利弗後至華林中，為波斯匿王更說四諦。唯阿難在，佛告阿難：『汝留坐具，汝亦宜去。』作是語已，是時世尊獨往女所。

“The Buddha instructed Ānanda: ‘Tell King Prasenajit and the monks to stroll about as they please.’ King Prasenajit said to the venerables: ‘The Tathāgata in his great compassion wishes to transform the courtesans; we should now all go far away.’ Having spoken thus, he backed away and withdrew, leaving only the one thousand two hundred and fifty monks standing in attendance behind the Buddha. The Buddha told Kauṇḍinya: ‘Lead your followers to engage in walking meditation in the grove.’ The five hundred monks, with the greatly wise Śāriputra as their leader, still joined their palms and attended upon the Buddha to his left and right. The Buddha told Śāriputra: ‘You too may go as you please and debate and discuss what is appropriate with the debate masters.’ The five hundred monks followed behind Śāriputra to the flower grove, where they further explained the Four Noble Truths for King Prasenajit. Only Ānanda remained. The Buddha told Ānanda: ‘Leave the sitting mat behind; you too should go.’ Having spoken these words, the Bhagavat then went alone to the place of the women.”
