Nuns’ rules and their analysis
Nuns’ Expiation (Pācittiya) 14
… at Sāvatthī in the Jeta Grove in Anāthapiṇḍika’s monastery. Now at that time the nun Thullanandā, stood together with and talked with a man, the one with the other, on a carriage road and in a cul-de-sac and at cross-roads, and she whispered in his ear and she dismissed the nun who was her companion. Those who were modest nuns … spread it about, saying:
“How can the lady Thullanandā stand together with … at cross-roads, and whisper in his ear and dismiss the nun who is her companion?” …
“Is it true, as is said, monks, that the nun Thullanandā stood together with … and dismissed the nun who is her companion?”
“It is true, lord.”
The enlightened one, the lord, rebuked them, saying:
“Whatever nun should stand together with or should talk with a man, the one with the other, on a carriage road or in a cul-de-sac or at cross-roads or should whisper in his ear or should dismiss the nun who is her companion, there is an offence of expiation.”
Cul-de-sac means: they depart by that (way) by which they entered.
Cross-roads means: it is called a place where four roads meet.
Man means: a human man, not a yakkha, not a departed one, not an animal; one who is learned, competent to stand, to talk.
Together with means: together.
The one with the other means: there is a man as well as a nun.
Should stand together with means: … offence of expiation.
Or should talk with means: … offence of expiation.
Or should whisper in his ear means: if she talks close into a man’s ear, there is an offence of expiation.
Or should dismiss the nun who is her companion means: if, desiring to indulge in bad habits, she then dismisses the nun who is her companion, there is an offence of wrong-doing. In leaving the region of sight or the region of hearing, there is an offence of wrong-doing. When she has left, there, is an offence of expiation. If she stands or talks, having left (the space of) a reach of the hand, there is an offence of wrong-doing. If she stands together with or talks with a yakkha or a departed one or a eunuch or an animal in human form, there is an offence of wrong-doing.
There is no offence if some learned friend comes to be (present); if, not wishing for a private place she stands or talks thinking about something else; if, not wishing to indulge in bad habits, she dismisses the nun who is her companion if there is something to be done; if she is mad, if she is the first wrong-doer.
