The Book of the Gradual Sayings
The Book of the Fives
Chapter XXI: Kimbila
Translated by E. M. Hare
 Thus have I heard:
Once the Exalted One dwelt near Sāvatthī;
and there he addressed the monks, saying:
'Yes, lord,' they replied;
and the Exalted One said:
Gruel. A thin porridge. Made by boiling oats, wheat or rye in water or milk.
"Monks, there are these five advantages from gruel.
It checks hunger,
keeps off thirst,
cleanses the bladder
and digests raw remnants of food.
Verily, monks, these are the five advantages of gruel.'
