Monks’ rules and their analysis
Monks’ Training (Sekhiya) 2
… in Anāthapiṇḍika’s monastery. Now at that time the group of six monks put on the upper robe hanging down in front and behind … “…
‘I will put on the upper robe all round me,’ is a training to be observed.”
The upper robe should be put on all round one having made both edges level. Whoever out of disrespect puts on an upper robe hanging down in front or behind, there is an offence of wrong-doing.
There is no offence … if he is the first wrong-doer.
