Udariyaṃ
Stomach contents
Udariyaṃ — the contents of the stomach, eighteenth item of the canonical list. Visuddhimagga VIII.122 spends an extended passage on the food in the process of being digested: 'whatever has been eaten, drunk, chewed, or licked is reduced in the stomach to a state like vomit, mixed with bile and phlegm'. This is the contemplation at its most direct; the meditator is asked to visualise the food they ate this morning in its present condition, neither metaphorically nor squeamishly. We render the rendered point at the navel landmark, the canonical centre of the digestive abdomen.
