So I have heard. At one time the Buddha was staying near Sāvatthī in the stilt longhouse of Migāra’s mother in the Eastern Monastery, together with several well-known senior disciples, such as the venerables Sāriputta, Mahāmoggallāna, Mahākassapa, Mahākaccāna, Mahākoṭṭhita, Mahākappina, Mahācunda, Anuruddha, Revata, Ānanda, and others.

Now at that time the senior monks were advising and instructing the junior monks. Some senior monks instructed ten monks, while some instructed twenty, thirty, or forty. Being instructed by the senior monks, the junior monks realized a higher distinction than they had before.
