The Discourse about Kassapa

Thus I heard: At one time the Gracious One was dwelling near Rājagaha, in Bamboo Wood, at the Squirrels’ Feeding Place. Then at that time venerable Mahākassapa was dwelling in the Pepper Cave, and was afflicted, suffering, and very sick.
Then venerable Mahākassapa at another time arose from that affliction. Then this occured to venerable Mahākassapa when he arose from that affliction: “Well now, I should enter Rājagaha for alms.”
Then at that time five hundred devatās were ready and eager to offer almsfood to venerable Mahākassapa. But venerable Mahākassapa, after refusing those five hundred devatās, having dressed in the morning time, after picking up his bowl and robe, entered Rājagaha for alms, going to the poor streets, to the wretched streets, to the weaver’s streets.
The Gracious One saw venerable Mahākassapa walking for alms in Rājagaha, going to the poor streets, to the wretched streets, to the weaver’s streets. Then the Gracious One, having understood the significance of it, on that occasion uttered this exalted utterance:

“Not nourishing another, well-known, controlled, established in the essential,
With pollutants destroyed, rid of faults: him I call a brāhmaṇa.”
