The King Pasenadi of Kosala dined off a tubful of rice. Then the King, replete and puffing, went to see the Blessed One, saluted him and sat down to one side. And the Blessed One, observing how he was replete and puffing, at once uttered this verse:
Those who always dwell in mindfulness,
Observing measure in the food they eat,
Find that their discomfort grows the less.
Aging gently, life for them is long.
Now just then Prince Sudassana was standing behind the king. And the king said to him:
"Come, my dear Sudassana, learn this verse from the Blessed One and recite it to me when you bring me my dinner, and I will arrange for you to be paid a daily allowance of a hundred pence in perpetuity."
"Very well, Your Majesty," said Sudassana [and did as he was told.]
After that the king made it a rule to eat no more than a quarter of a tubful of rice. Thus it came about that on a later occasion King Pasenadi, his body in good shape, stroked his healthy limbs and fervently exclaimed: "Truly the Blessed One has doubly shown compassion for my welfare, both in this life and in the life to come!"
