Eight short lines, one repeated phrase, and a whole experience of reading turned upside down: "Sister Nina" is a poem that rewards slow attention precisely because it is so small. Its subject is a girl, evidently blind, who reads with her fingertips. The title and the details suggest this, though the poem never uses the word "blind." We infer it from the "lifted mark" and the dark, and that restraint is the first sign of how carefully the poem is made.
The central idea is a quiet reversal. We usually imagine reading as something done with light: eyes, a lamp, an open page. Here the book "speaks words divine" without any of that. The final line makes the point outright: "She reads and smiles in the dark." Darkness, which we would normally associate with loss or exclusion, becomes simply the place where Nina reads, and where she is happy. The poem refuses pity. Nobody in it laments what she cannot see; the attention is all on what she can do.
The word that holds everything together is "touch." It appears in the first line, returns in the second stanza ("with a touch of a finger"), and sits alongside the repeated "finger" so often that the poem almost feels fingered itself, worn smooth by handling. This repetition is deliberate. The first stanza opens with "The mere little touch of her finger" and then, in line three, repeats nearly the same words: "The mere little touch of a finger." Notice the small shift from "her" to "a." The first time, the finger belongs to Nina; the second time, it could be anyone's, as if the poem were widening its claim, saying this humble gesture is the real miracle, whoever performs it. The word "mere" is doing interesting work too. It sounds dismissive, but the poem uses it to build wonder: how can something so slight produce something "divine"?
That adjective is the poem's boldest choice. "Words divine" lifts an ordinary schoolroom act into the language of revelation, and the poem never explains or qualifies it. Whether the book is sacred scripture or simply a book is left open, but the effect is the same: reading is presented as a kind of grace. The image of the finger moving "along a line" is plain and physical, and the contrast between that modest movement and the grand word "divine" gives the stanza its charge.
The second stanza turns from the act to the feeling behind it. "Gay with her love to finger / She feels each lifted mark" is the most compressed sentence in the poem. "Gay" here means joyful, and it is attached to love: Nina's pleasure is not in being clever but in the sheer affection she has for the process. "Lifted mark" is a precise, almost technical image of raised dots on a page, yet "lifted" also carries a suggestion of being raised up, elevated. Then comes "And lo!", an old-fashioned exclamation that works like a small drumroll, announcing a discovery as though each reading were happening for the first time.
Formally, the poem is built on a loose, singing rhythm of alternating longer and shorter lines, roughly four beats followed by three. The rhyme scheme links the second and fourth lines of each stanza: "divine" with "line," "mark" with "dark." Those pairs matter. In the first stanza, "divine" is tied to "line," joining the holy to the humble. In the second, "mark" is tied to "dark," so the raised dot on the page and the darkness around it end up in the same sound-world, as though one answers the other. The lines that do not rhyme, the ones ending in "finger," simply repeat the word instead, which means the poem rhymes by return rather than by variety. That insistence gives it the feel of a chant or a nursery verse, appropriate for a poem about a child learning her letters.
What makes the poem worth reading is how little it asks for sympathy and how much it gives instead: respect. In just a few lines it shifts our idea of what reading is, locating it in the hand and the heart rather than the eye, and it ends not on a note of sorrow but on a smile.
