「若比丘尼，受他請，食前食後行到諸家，不近白餘比丘尼，除因緣。波逸提。因緣者，衣時，是名因緣。

"If a bhikṣuṇī, having accepted an invitation from another, goes to visit various households before or after the meal without informing a nearby bhikṣuṇī, except on an appropriate occasion, it is a pāyattika. An appropriate occasion is the robe-making season; this is called an appropriate occasion.
