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

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

That is what the Buddha said. On this it is said:

“Those who know the all as all, 
are not attracted to anything. 
They completely understand all, 
and have risen above all suffering.”

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