This poem is a series of short meditations on death. The poet begins by surveying his surroundings, "Here / the air is sharp-edged / like the air will be / at the end of your days." But, no, the poem is not about the abstract subject of death--the poet encounters his own death. "At least I won't have to / know myself then, / won't have to see my own corpse."
Encountering death is itself a journey, "Each lap of the journey / dangerous, / the destination / kept secret." Yet he realizes that the meditation, the journey, has "nothing in common with / what the end of my days / will be." Death is irreducibly unimaginable and alien.
