Na bhuñjamānena sabbo hattho mukhe pakkhipitabbo.One should not put one’s whole hand in one’s mouth while eating. Yo anādariyaṁ paṭicca bhuñjamāno sabbaṁ hatthaṁ mukhe pakkhipati, āpatti dukkaṭassa.If a monk, out of disrespect, puts his whole hand in his mouth while eating, he commits an offense of wrong conduct.

Anāpatti—There is no offense: asañcicca …pe…if it is unintentional; ādikammikassāti.if he is the first offender.
