Mahīśāsaka Vinaya
Bhikkhunī Vibhaṅga
Confession 202
Origin Story
At that time, the bhikkhunīs lay on their backs in a place where water dripped from the roof. The drops entered into their vaginas and sexual desire arose in their minds. Thereupon, they returned to lay life, or became non-Buddhist renunciates. 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 lies on her back in a place where water flows down, it’s a pācittiya.’”
Explanations
The remainder is as explained above.
