Cullavagga - First Khandhaka: Chapter 33

33.

cases in which it is according to law, the six permissive cases in which it can
be carried out if the Samgha likes, and the eighteen divisions of the right

and 5, reading 'Ukkhepaniya-kamma for not renouncing a sinful doctrine,' instead
of 'Tagganiya-kamma. ]
