This was said by the Buddha, the Perfected One: that is what I heard.

“Mendicants, without directly knowing and completely understanding conceit, without dispassion for it and giving it up, you can’t end suffering. By directly knowing and completely understanding conceit, having dispassion for it and giving it up, you can end suffering.”

The Buddha spoke this matter. On this it is said:

“These folk are caught up in conceit, 
tied by conceit, delighting in existence. 
Not completely understanding conceit, 
they return in future lives.

Those who have given up conceit, 
freed in the ending of conceit, 
vanquishers of the tie of conceit, 
have risen above all suffering.”

This too is a matter that was spoken by the Blessed One: that is what I heard.
