This was said by the Blessed One, said by the Arahant, as I have heard:

"Bhikkhus, abandon one thing; I am your guarantor for non-returning. What one thing? Bhikkhus, abandon greed; I am your guarantor for non-returning.

The Blessed One spoke on this matter. In this regard, it is said:

"Overcome by greed, through which, beings go to an unfortunate destination; Completely comprehending that greed, those seeing clearly abandon it; Having abandoned it, they do not return, to this world at any time."

This matter too was spoken by the Blessed One, as I have heard.
