佛說處處經 1.44

1.44

佛言：「昔有一比丘，坐禪行道，佛弟難陀飲酒醉，數往來到其邊歌戲。比丘白佛言：『我欲避之去。』佛言：『不須，是難陀於今當得道迹。』佛即遣阿難往到其家，摩訶迦葉隨其後。舍利弗為說經，目揵連現神足，難陀便歡喜，即得道迹。佛說比丘行道，當但堅心者，何憂不得道？比丘聞佛說此語，歡喜意解便得阿羅漢。」

The Buddha said: "Formerly, there was a monk sitting in meditation and practicing the Way. The Buddha's younger brother Nanda was drunk with wine and repeatedly came to his side singing and jesting. The monk addressed the Buddha, saying: 'I wish to avoid him and leave.' The Buddha said: 'No need; this Nanda will now attain stream-entry.' The Buddha then sent Ānanda to his home, with Mahākāśyapa following behind him. Śāriputra explained the scriptures to him, and Maudgalyāyana displayed supernatural powers; Nanda then rejoiced and immediately attained stream-entry. The Buddha said that when a monk practices the Way, if he only keeps a steadfast mind, why worry that he will not attain the Way? Hearing the Buddha speak these words, the monk's mind opened in delight, and he attained arhatship."
