18.60

比丘問何緣。得須陀洹。而受此苦。笈多答曰。先身出家。眾僧坐禪其為維那。有一羅漢。居此惡病。搔刮作聲。維那語言。惡蟲食汝。而作此聲。即牽臂出言。汝入旃陀羅室去。阿羅漢語維那。汝當精進。莫往生死受苦。是維那即懺悔之。懺悔竟得須陀洹果。不復精進。今小兒是也。牽羅漢出。今生旃陀羅處。受此報也。比丘怖畏勤精進。即得阿羅漢果（出阿育王經第十卷）。

The monk asked, "Due to what cause did he attain srotāpanna yet suffer this misery?" Upagupta replied: "In a former life he left home. While the assembly of monks sat in meditation, he acted as the karmadāna. There was an arhat who suffered from this foul disease, scratching and scraping with a loud noise. The karmadāna said to him: 'Vile worms are devouring you that you make such noise!' He then seized his arm, dragged him out, and said: 'Go into a caṇḍāla's house!' The arhat said to the karmadāna: 'You should be vigorous; do not go on suffering bitter pain in birth and death!' This karmadāna immediately repented. After repenting, he attained the fruit of srotāpanna, but was no longer vigorous. The young boy today is he. Because he dragged the arhat out, he is now born in a caṇḍāla's dwelling, suffering this retribution." The monk, terrified, practiced diligent vigor and immediately attained the fruit of arhat.
