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

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

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

“When overcome by greed 
beings go to a bad place. 
Having rightly understood that greed, 
the discerning give it up. 
Once they’ve given it up, 
they never return to this world.”

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