Musāvādasikkhāpada

Vinayapiṭaka · Bhikkhu Vibhaṅga (2) · Vol. 2 · Section 208

[208] A fully ordained one (upasampanna), desiring to insult a fully ordained one, desiring to disparage him, desiring to humiliate him, addresses one of high standing with reference to the high — [addressing] a Gotama, a Moggallāna, a Kaccāyana, a Vāseṭṭha — saying, "You are a Gotama! You are a Moggallāna! You are a Kaccāyana! You are a Vāseṭṭha!": for each utterance there is an offence of pācittiya.
