He lived in Macchikāsaṇḍa, in a monastery (the Ambāṭakārāma) provided by Citta. Citta used to invite Sudhamma to his house for meals. One day Sāriputta, at the head of several eminent monks, visited Macchikāsaṇḍa and stayed in the monastery. Citta heard Sāriputta teach (and became a Once-returner, says DhA), and, at the end of the discourse, invited him and the monks to his house the next day. He also invited Sudhamma, but because he had been invited after the others, Sudhamma refused to go. Early the next day he visited Citta’s house to see what offerings had been prepared, and after seeing them, remarked that one thing was missing: sesame cakes (tilasaṅgulikā). Then Citta rebuked him, comparing him to a crow, the offspring of a cock and a crow. Sudhamma left the house in anger, and going to Sāvatthi, reported the matter to the Buddha. The Buddha blamed Sudhamma and said that the Saṅgha should impose the paṭisārāṇīya-kamma on him. Sudhamma, thereupon, went to Macchikāsaṇḍa to ask pardon of Citta, but Citta would not forgive him. The Buddha then gave him a companion, and together they went to Citta, and Sudhamma again asked pardon for his fault. Citta pardoned him and asked to be pardoned himself (Vin.i.15-20; cf. DhA.ii.74 ff). Later Sudhamma became an Arahant. AA.i.210.
