1.54

昔西域傳法羅漢優波笈多。將一弟子。乞食至旃陀羅舍。有旃陀羅子。得須陀洹果。身有惡病。一切身體為蟲所食。口氣臭穢。弟子問言。何緣須陀洹人而受此報。笈多答言。此人先世出家。其為維那時眾中有一羅漢。居此惡病。搔刮作聲。維那語。蟲食汝而作此聲。即牽臂出言。汝入旃陀羅室去。羅漢語言。汝當精進。莫往來生死受苦。於是維那即便懺悔。悔竟得須陀洹果。今此小兒是也。

Anciently, in the Western Regions, the arhat Upagupta, who transmitted the Dharma, was leading a disciple begging for alms and arrived at the house of a caṇḍāla. There was a son of the caṇḍāla who had attained the fruit of a srotaāpanna, yet had a terrible disease: his entire body was devoured by worms, and his breath was foul and fetid. The disciple asked, "For what reason does a srotaāpanna suffer this retribution?" Upagupta replied, "In a past life, this man entered the monastic life. When he was serving as the karmadāna, there was an arhat in the assembly who suffered from this terrible disease and was making scratching noises. The karmadāna said, 'Are worms eating you that you make such noises?' He then grabbed his arm, dragged him outside, and said, 'Go into the quarters of the caṇḍālas!' The arhat said to him, 'You should be diligent; do not wander back and forth in saṃsāra and suffer torment.' Thereupon, the karmadāna immediately repented. Having repented, he attained the fruit of a srotaāpanna. It is this child today."
