The poem treats the plainest things, a meal of peas, pork and boiled beef, as a kind of worship. The speaker says "we come close to the land," and the way to do it is through the body: eating "with great love" and even, in a surprising and funny line, shitting "with all imaginable respect." Nothing about being physical is treated as shameful. Eating and digesting are both part of the same cycle that ties people to the ground they live on.
The language then widens into "the land / infinite place / rich world," short phrases that feel like someone catching their breath at how big it all is. The final image shifts to something almost ceremonial: a man "almost drowned in joy" honoring an oak with a gilded crown. The title, which looks like an old-sounding word, suggests a ritual feel, though the poem itself only lets us infer that. The mood is humble, grateful and quietly ecstatic, mixing earthy humor with real reverence.
