This is how I have heard from the Blessed One. At one time the Blessed One was staying in the city of Rājagaha in the Bamboo park at the squirrels’ garden. Those days Mahākassapa Thero stayed in the Pipphali cave. He was very sick, in great pain and was severely ill. After a couple of days, he recovered from that sickness. One day he thought to himself, “I shall enter the village of Rājagaha to beg for food.”
At that time five hundred gods were eagerly preparing to go to Mahākassapa Thero in order to offer food to him. However, Mahākassapa Thero turned down those five hundred gods’ food. He wore his robe, took his bowl, double robe, and entered the village of Rājagaha for alms. He was walking in the street of very poor people who earned their living by weaving cloths. The Blessed One with his divine eye saw Mahākassapa Thero walking for alms in the street of very poor people who earned their living by weaving cloths.
Then, the Blessed One who realised the quality of detachment of Mahākassapa Thero, spoke the following inspired verse,
“The liberated one doesn’t feed others. Everybody knows his noble qualities. He is well restrained. He well established in the most essential, Nibbāna. He has destroyed all taints and eradicated defilements. Him I call a brāhmin.”
