[313] A bhikkhu who, having approached the bhikkhunīs' dwelling, exhorts bhikkhunīs falls into two offenses (āpatti): while he is exhorting, there is an offense of wrong-doing (dukkaṭa) in the act of undertaking; when the exhortation is completed, there is an offense entailing expiation (pācittiya).
