At one time the Buddha was staying at Sāvatthī in the Jeta Grove, Anāthapiṇḍika’s Monastery. At that time a number of nuns who had completed the rainy-season residence in a village monastery went to Sāvatthī. The nuns there asked them, “Venerables, where did you spend the rains residence? Where did you invite the Sangha of monks for correction?” “We didn’t invite the Sangha of monks for correction.” The nuns of few desires complained and criticized them, “How could nuns who have completed the rains residence not invite the Sangha of monks for correction?” … “Is it true, monks, that nuns didn’t do this?” “It’s true, sir.” The Buddha rebuked them … “How could nuns not do this? This will affect people’s confidence …” … “And, monks, the nuns should recite this training rule like this:

Final ruling ‘If a nun who has completed the rainy-season residence does not invite correction from both Sanghas in regard to three things—what has been seen, heard, or suspected—she commits an offense entailing confession.’”

Definitions A: whoever … Nun: … The nun who has been given the full ordination in unanimity by both Sanghas through a legal procedure consisting of one motion and three announcements that is irreversible and fit to stand—this sort of nun is meant in this case.
