"Most readers make three false assumptions when addressing an unfamiliar poem. The first is assuming that they should understand what they encounter on the first reading, and if they don't, that something is wrong with them or with the poem. The second is assuming that the poem is a kind of code, that each detail corresponds to one, and only one, thing, and unless they can crack this code, they've missed the point. The third is assuming that the poem can mean anything readers want it to mean."

Like all literature worth reading, poetry has the power to engage the heart and the mind, to delight, and challenge. Great poems blossom in meaning when they're read carefully and discussed with close friends, classmates, or fellow group members.
