The Discourse on Quarrelsome Speech
1079.
"Do not, monks, engage in quarrelsome speech -
'You do not understand this Teaching and discipline, I understand this Teaching and discipline.
How could you understand this Teaching and discipline!
You are practising wrongly, I am practising rightly.
What I say is consistent, what you say is inconsistent.
What should have been said first you said last, what should have been said last you said first.
What you have thought out for so long has been turned inside out.
Your doctrine has been refuted, go and free yourself from your doctrine.
You are proven wrong, disentangle yourself if you can.'
What is the reason for this?
This talk, monks, is not connected with benefit, is not fundamental to the holy life, does not lead to disenchantment, to dispassion, to cessation, to peace, to direct knowledge, to highest enlightenment, to Nibbāna.
"But when speaking, monks, you should speak 'This is suffering'; you should speak 'This is the origin of suffering'; you should speak 'This is the cessation of suffering'; you should speak 'This is the practice leading to the cessation of suffering.' Etc. exertion is to be done." The ninth.
