These five arhats were the first members of the Noble Sangha, the "community of enlightened beings" with the Buddha as teacher and guide.
While the Buddha was staying in the Deer Park at Isipatana, a suburb of Varanasi (Benares), a rich young man, an ordinary householder from the neighborhood named Yasa, came to see him.
- [The ordination of Yasa was one of the scenes of the Buddha's life to be sculptured in the Relic Chamber of the Mahā Stūpa (Mhv.xxx.79). And according to the Anguttara Nikaya Commentary (AA.i.218f), Sujātā Senānīdhītā (the woman who gave Siddhartha a meal of rich food that restored him back to health just before his enlightenment) was Yasa's mother. She became a stream winner after listening to the Buddha's sermon.]
The Buddha had a mission for them. Now that they had learned the teaching and reached the goal, he sent them out to teach others so that those who were ready to hear the Dharma might give ear and practice it and thereby be saved from all trouble and distress.
Monks like you are the proper kind of monks to spread abroad this Dharma among all the peoples and places of the world.” [It may well be that they were not limiting their mission to this planet or "island" (dipa) but taking it much farther abroad.] More
