One day the Buddha visited a monastery. While he was there he came across a chamber where a monk lay in great pain caused by a loathsome disease. Although there were many other monks at the monastery, not one of them was concerned about their sick brother. The Buddha, beholding this woeful situation, began to look after the suffering man. He called Ananda and together they bathed the monk, changed his dirty bed and eased his pain.
Then the Buddha admonished the monks of the monastery for their neglect and encouraged them to nurse the sick and care for the suffering. He concluded by saying, “Whosoever serves the sick and suffering, serves me.”
This is the same story told by Christians in Matthew 25:34-40:
“Then the King will say to those on his right, ‘Come, you who are blessed by my Father; take your inheritance, the kingdom prepared for you since the creation of the world. For I was hungry and you gave me something to eat, I was thirsty and you gave me something to drink, I was a stranger and you invited me in, I needed clothes and you clothed me, I was sick and you looked after me, I was in prison and you came to visit me.’
‘“Then the righteous will answer him, ‘Lord, when did we see you hungry and feed you, or thirsty and give you something to drink? 38 When did we see you a stranger and invite you in, or needing clothes and clothe you? When did we see you sick or in prison and go to visit you?’
“The King will reply, ‘Truly I tell you, whatever you did for one of the least of these brothers and sisters of mine, you did for me.’”
