Elizabeth Barrett Browning's sonnet follows one thought through a very short life. It starts as a pleasure, becomes a possession the speaker wants to keep, and ends as a wound. A single thought settles "like a flower upon mine heart," and others gather round it "like bees / For multitude and thirst of sweetnesses." The speaker is delighted, and that delight leads straight to greed. She wishes for the skill of "the Greek whistler," a figure who could lure whole swarms from orange-trees to "wharf and mart," so that she might "hive" such thoughts and "please / My soul so, always." The poem's real subject is that last word. She wants happiness not just to arrive but to stay, under her control.
The poem punishes that wish almost at once. The turn comes in the middle of line 8, where the speaker interrupts herself with "foolish counterpart / Of a weak man's vain wishes!" The sonnet's usual hinge falls a few words early, as if she can't wait until the octave ends to scold herself. "While I spoke" then suggests the change happens in the act of wanting. The flower becomes "nettle-rough," and the bees, now just "thoughts, called bees," sting her "to festering." The image carries the poem's logic. Bees were the sweetness-seekers, and they were also the stingers. The flower and the nettle are both plants, the difference being what happens when you touch them. "Festering" is the harshest word in the poem because it describes a hurt that doesn't end with the sting. It goes on working under the skin.
Then Reason arrives, and the verb is telling: she "woke." The speaker's daydream, it seems, was a kind of sleep. Reason's advice is "entertain / Your best and gladdest thoughts but long enough," and the verb carries two senses. To entertain a thought is to amuse yourself with it, but it is also to host it, as one hosts guests, or bees in a hive. Stay with them long enough, Reason says, "and they will all prove sad enough to sting." One reading, and it is only a reading, is that lingering on happiness makes us notice how fragile it is. The better the thought, the more there is to lose.
The form supports this. The poem is a Petrarchan sonnet, and the octave rhymes *abba abba*. Four lines end in the same *-art* sound ("heart," "art," "mart," "counterpart"), while the other four rhyme on a long *e* ("bees," "sweetnesses," "trees," "please"). The effect is tightly packed, almost humming, a hive of repeated sounds. The sestet loosens. Its rhymes run *cde cde*, and the last pair, "festering" and "sting," match only in their closing *-ing*. The neatness of the octave has come apart by the end, and the poem's final word is the sting itself. The reader is caught the same way the speaker was: carried along by the pleasant sounds and then hit by the last syllable.
The rhythm is a steady iambic pentameter, which keeps the voice calm and conversational even as the mood darkens. The one clear interruption is Reason's parenthesis, "(cried Reason as she woke)," which breaks into her own speech like a stage direction. That makes the moment feel dramatic, a small scene between two parts of one mind. Reason is not a gentle comforter here. She is blunt, and she has the last word.
What makes the poem worth reading is how much it fits into fourteen lines. It begins with the pleasure of an idea and ends with a sour general rule, and it gets from one to the other by letting a single comparison grow. The bee is first a picture of sweetness, then of greed, then of pain, and the poem never needs a second image. It also admits that the speaker's wish was foolish. She does not blame the thoughts for stinging. She blames her own wish to keep them, and that honesty makes the final warning feel earned, even if some readers will want to argue with it.
