“Is it true, as is said, monks, that nuns neither … nor ask for exhortation?”

“It is true, lord.”

The enlightened one, the lord, rebuked them, saying:

“How, monks, can nuns neither … nor ask for exhortation? It is not, monks, for pleasing those who are not (yet) pleased … this rule of training:

“Every half month a nun should desire two things from the Order of monks: the asking as to (the date of) the Observance day and the approaching for exhortation. For her who transgresses this, there is an offence of expiation.”

Every half month means: every Observance day.

Observance day means: the two Observance days, that on the fourteenth day and that on the fifteenth day.

Exhortation means: the eight important rules.
