Dutiyasiṅgāla sutta: A Jackal (2nd)

At Sāvatthī.

“Mendicants, did you hear an old jackal howling at the crack of dawn?”

“Yes, sir.”

“There might be some gratitude and thankfulness in that old jackal, but there is none in a certain person here who claims to follow the Sakyan.

So you should train like this: ‘We will be grateful and thankful. We won’t forget even a small thing done for us.’ That’s how you should train.”
