The Buddha finds Anuruddha, Nandiya, and Kimbila living in exemplary harmony—goodwill in body, speech, and mind; shared duties; noble silence; and an all-night Dhamma discussion every fifth day. They can enter the four jhānas and the formless attainments at will, culminating in the exhaustion of the mental defilements from having seen with wisdom.

When the Buddha fails to achieve reconciliation among quarrelsome bhikkhus at Kosambi, he withdraws into solitude and later encounters an inspiring community of monks devoted to liberation. He teaches them the path of inner purification based on his own practice prior to full awakening—discerning and abandoning eleven subtle impurities of mind, developing collectedness in three ways, and realizing unshakable liberation.
