[842] Origin at Sāvatthī. Now at that time the group-of-six bhikkhus, while eating, put the whole hand into the mouth. …
"'While eating, I will not put the whole hand into the mouth' — thus the training is to be undertaken."
The whole hand is not to be put into the mouth by one who is eating. Whoever, out of disrespect, while eating puts the whole hand into the mouth: an offence of wrong-doing (dukkaṭa).
There is no offence: if it is unintentional; if he is unmindful; if he does not know; if he is ill; in emergencies; if he is mad; if he is the first offender.
