[265] At that time the Buddha, the Blessed One, was dwelling at Sāvatthī, in the Jetavana, Anāthapiṇḍika's park. Now at that time the bhikkhunī Thullanandā was learned, an eloquent reciter, confident, skilled at giving a talk on the Dhamma. Bhaddā Kāpilānī too was learned, an eloquent reciter, confident, skilled at giving a talk on the Dhamma, and was held in high esteem. People, thinking, "The lady Bhaddā Kāpilānī is learned, an eloquent reciter, confident, skilled at giving a talk on the Dhamma, and held in high esteem," would attend upon Bhaddā Kāpilānī first, and afterwards attend upon the bhikkhunī Thullanandā. The bhikkhunī Thullanandā, overcome by envy, thinking, "So these are the ones, it seems, who are of few wishes, contented, secluded, and unentangled — these who dwell abounding in persuading and abounding in hinting!" — walked up and down in front of Bhaddā Kāpilānī, and stood, and sat, and lay down, and recited, and had others recite, and performed her rehearsal.
Those bhikkhunīs who were of few wishes … criticized, complained, and spread it about: "How can the lady Thullanandā deliberately cause discomfort to the lady Bhaddā Kāpilānī?" …
"Is it true, bhikkhus, as they say, that the bhikkhunī Thullanandā deliberately causes discomfort to Bhaddā Kāpilānī?"
"It is true, Blessed One."
The Buddha, the Blessed One, rebuked them: "How, bhikkhus, can the bhikkhunī Thullanandā deliberately cause discomfort to Bhaddā Kāpilānī? This, bhikkhus, is not for the confidence of those without confidence …
"And thus, bhikkhus, let the bhikkhunīs recite this training rule:
"Should any bhikkhunī deliberately cause discomfort to a bhikkhunī, there is an offense of pācittiya."
