Monks’ rules and their analysis

Monks’ Training (Sekhiya) 49

… in Anāthapiṇḍika’s monastery. Now at that time the group of six monks ate putting out their tongues … “…

‘I will not eat putting out the tongue,’ is a training to be observed.”

One should not eat putting out the tongue … offence of wrong-doing.

There is no offence if it is unintentional … if he is the first wrong-doer.
