Tena samayena buddho bhagavā sāvatthiyaṁ viharati jetavane anāthapiṇḍikassa ārāme.At one time the Buddha was staying at Sāvatthī in the Jeta Grove, Anāthapiṇḍika’s Monastery. Tena kho pana samayena chabbaggiyā bhikkhū uppathena gacchantā pathena gacchantassa dhammaṁ desenti …pe….At that time the monks from the group of six were walking next to the path while giving teachings to people walking on the path. …

“Na uppathena gacchanto pathena gacchantassa agilānassa dhammaṁ desessāmīti sikkhā karaṇīyā”ti.
desessāmīti → desissāmīti (bj)“‘I will not give a teaching while walking next to the path to anyone walking on the path who is not sick,’ this is how you should train.”

Na uppathena gacchantena pathena gacchantassa agilānassa dhammo desetabbo.One should not give a teaching while walking next to the path to anyone walking on the path who is not sick. Yo anādariyaṁ paṭicca uppathena gacchanto pathena gacchantassa agilānassa dhammaṁ deseti, āpatti dukkaṭassa.If a monk, out of disrespect, gives a teaching while walking next to the path to someone walking on the path who is not sick, 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.
