Mahīśāsaka Vinaya
Bhikkhunī Vibhaṅga
Confession 190
Origin Story
At that time, the bhikkhunīs recited non-Buddhist magic. The lay people criticized them: “These people recite non-Buddhist magic, they don’t have the intention to seek the path.” … “I now lay down a precept for the bhikkhunīs, all as explained in ‘reciting texts on medical treatments’. From now on, this precept should be recited thus:
Final Ruling
‘If a bhikkhunī recites non-Buddhist magic, or teaches others to recite it, it’s a pācittiya.’”
Explanations
For a sikkhamānā and a sāmaṇerī, it’s a dukkaṭa.
