1At Sāvatthī. "Bhikkhus, did you hear an old jackal howling at the flush of dawn?"

"Yes, venerable sir."

"There may be some gratitude and thankfulness in that old jackal, but there is no gratitude and thankfulness in a certain person here claiming to be a follower of the Sakyan son. [n.377] Spk: This too is said with reference to the behaviour of Devadatta. Spk relates an anecdote about a jackal who had been rescued from a python by a farmer. When the python grabbed the farmer, the jackal, out of gratitude, went to the farmer's brothers and led them to the scene, thereby enabling them to rescue the farmer.

"Therefore, bhikkhus, you should train yourselves thus: ‘We will be grateful and thankful, and we will not overlook even the least favour done to us.’ Thus should you train yourselves."
