Mahīśāsaka Vinaya
Bhikkhunī Vibhaṅga
Confession 182
Origin Story
At that time, the bhikkhunīs sat facing lay people and taught dhamma with their bodies leaning close to each other, as if they were having a romantic talk. From this, defiled attachment arose in their minds. Thereupon, they returned to lay life, or became non-Buddhist renunciates. The lay people criticized them. When the senior bhikkhunīs heard it, they criticized them in all kinds of ways, … “I now lay down a precept for the bhikkhunīs, as explained above. From now on, this precept should be recited thus:
Final Ruling
‘If a bhikkhunī sits facing a lay person and teaches dhamma with their bodies leaning closely towards each other, it’s a pācittiya.’”
Explanations
For a sikkhamānā and a sāmaṇerī, it’s a dukkaṭa.
