Monks’ rules and their analysis
Monks’ Training (Sekhiya) 43
‘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.
