4 patidesaniya (verbally acknowledged violations)

Four patidesaniya are (monastic) violations which must be verbally acknowledged:

1. Accepting and eating food from an unrelated bhikkuni.

2. Accepting and eating food after a bhikkuni has instructed the donors on who to give what food, and none of the bhikkus rebuke the bhikkuni.

3. Accepting and eating food from a family that the sangha designates as "in training", that is, preparing to becoming arahants, unless if the monk is sick.

4. Accepting and eating food from a family living in a dangerous location, unless if the monk is sick.

(from the Vinaya Pitaka)
