Twelve short lines, and the poem starts by borrowing a famous idea only to push past it. "Not only time's / relative," says the speaker, echoing the familiar claim from physics, and then adds what the cliché leaves out: "There's space." The title, lowercase and bare, does double duty. Space is the gap between places, but it is also room to move, to wander, to be restless. The poem keeps both meanings in play.
What follows is a surprise. Instead of galaxies, we get "the zigzag paths / over dried needles." Judging by the imagery, this is a forest floor, probably pine, and the scale has shrunk to a walker's eye level. "Zigzag" looks like what it means, with its doubled z's turning back on themselves, and it suggests a route that never goes straight. Then comes the paradox at the poem's center: "I've found great distance / in a single step." Distance here is not measured in miles. A single step can be enormous depending on what it crosses, whether a gap between people or between one self and another.
The next image grounds this in effort: "the plod that connects / me to young flowers." "Plod" is a deliberately unglamorous word, flat and heavy, a verb for tired feet. Yet it is given the poem's most hopeful job, connecting. Closeness is earned by slow, patient walking, not by leaps. The dried needles and young flowers also set old against new, a contrast the ending picks up.
The second half turns outward and into the future. "Lightness'll come crossing / mouthy oceans" swaps the forest for the sea, and the grammar loosens along with the scale. The contraction "Lightness'll" is a spoken, casual shortening that makes the speaker sound like someone talking rather than lecturing. "Mouthy" is the most inventive word in the poem. It makes the oceans chattering, cheeky, full of speech, and the next word confirms it: "tongues." Crossing the water means meeting other languages. Then the syntax bends again: "to teach me close." Close is normally an adjective, but here it works like a noun, a thing to be taught, which makes closeness a skill learned rather than a place reached.
That line completes a quiet reversal. In the first half, great distance was found in one small step. In the second, closeness has to be learned by crossing whole oceans. Near and far keep trading places, and the poem suggests that space is felt, not measured.
The form supports this. There is no rhyme and no fixed meter, but most lines hover around five syllables, short enough that each one feels like a counted step. Enjambment keeps tripping the reader at awkward moments: "time's / relative," "tongues / to teach me close," "Mine's / an old." Each break is a small gap on the page, so the poem enacts the space it describes. Sound does gentle work too. The hissing of "space," "zigzag," "paths" and "needles" gives way to the soft l's of "Lightness'll" and "old," as if the poem itself grows lighter.
The final sentence, "Mine's / an old, restless soul," is the plainest in the poem. The line break after "Mine's" holds back the admission for a beat, and then it lands without decoration. It also explains what came before. "Old" echoes the dried needles, and "restless" is the zigzag path turned into character. The wandering route and the long plodding step both belong to a soul that cannot settle.
The poem's significance lies in that economy. It takes a big abstract idea and tests it against a walk through trees, a handful of flowers and the sound of other languages. In twelve lines it moves from physics to the speaker's own temperament, and it ends not with an answer but with a self-portrait that quietly accounts for everything before it.
