Mahāsaṅghika Vinaya

Bhikkhunī Pakiṇṇaka

Pakiṇṇaka 15

The Buddha was staying in Sāvatthī. At that time, bhikkhunīs went to the women’s bathing place to wash their menstrual cloths. The women were upset and said: “These renunciates are staining the water red like this.” For this reason the bhikkhunīs went and informed … The Buddha said: “From now on, it’s no longer allowed to wash a menstrual cloth at the women’s bathing place. If (a bhikkhunī) washes one, she breaks a minor vinaya rule.” This is called the rule on washing menstrual cloth at the women’s place.
