In the Ancient Mariner's story itself, the spiritual and temporal worlds are confounded the moment the sailors cross the equator. Suddenly the natural world - which is closely connected to the spiritual world - makes the sailors lose control of their course. The storm drives them into an icy world that is called "the land of mist and snow" throughout the rest of the poem. The word "rime" can mean "ice", and can also be interpreted as an alternate spelling of the word "rhyme." Therefore, as much as the poem is the rhymed story of the Ancient Mariner, it is also the tale of the "land of mist and snow": the "rime", where the Ancient Mariner's troubles begin. By calling the poem "The Rime of the Ancient Mariner," Coleridge equates the "rhyme" or tale with the actual "rime" or icy world. As we learn at the story's end, the Ancient Mariner is condemned to feel perpetual pangs of terror that force him to tell his "rhyme," a fate just as confining and terrifying as the "rime" itself is initially for the sailors.
