Thus it was said by the Blessed One, said by the Arahant, I have heard:

“Bhikkhus, abandon one thing; I am your guarantor for non-returning. What one thing? Bhikkhus, abandon contempt (ungratefulness); I am your guarantor for non-returning.”

The Blessed One spoke this matter. Therefore, it is said thus:

“When overcome by contempt or ungratefulness, beings go to a bad destination; Completely comprehending contempt and ungratefulness, those with insight abandon it; Having abandoned it, they do not come again, to this world at any time.”

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