Vinaya Pitaka - Monastic Rules
Bhikkhu Vibhanga - Sekhiya 43: Not to speak with a full mouth.
- Translated from the Pali by I.B. Horner.
… in Anāthapiṇḍika’s monastery. Now at that time the group of six monks talked with a mouthful in the mouth … " …
‘I will not talk with a mouthful in the mouth,’ is a training to be observed."
One should not talk with a mouthful in the mouth. Whoever out of disrespect talks with a mouthful in the mouth, there is an offence of wrong-doing.
There is no offence if it is unintentional … if he is the first wrong-doer.
