Why does the poet Robert Frost repeat the last line “And miles to go before I sleep” in his poem “Stopping by Woods on a Snowy Evening”? Or, What is achieved by the repetition of the line in the poem?
Last two lines are the most important in this poem. The poet here says two different things in both lines. In the second last line he describe that he is a long way from home and it will take him a lot of time to reach his resting place. The last line describes that the narrator has miles of time or lots of time before he gets his final rest, death which he wants or desires but before getting that rest he has promises to keep or duties to fulfill .
The last line of the poem is the most important one and holds the key to the allegorical meaning of the poem. It is only for this last line ‘And miles to go before I sleep’ that the poem has been highly acclaimed. It suggests that we have a lot of things to do before we die. So we cannot stop and watch at a beautiful thing and waste our time. So this line is repeated to emphasize the point the poet wants us to get well.

“And miles to go before I sleep” the poet says that he has a lot of things to do in this world before he sleeps. The word sleep here symbolises the final sleep – death.
The last two lines – in fact, the entire “d, d, d, d” rhyme scheme of the closing stanza – is Frost’s brilliant resolution to the rhyme scheme problem he created for himself in the previous stanzas. It’s brilliant not only because it solved the problem but because it’s both lovely and an evocative echo that’s made legions of readers want to interpret it.
Only Frost knows what, if any, deeper meaning there is to those two lines or, for that matter, the entire poem. Be careful about any certainty you might feel, because another of his works, The Road Not Taken, is almost universally misinterpreted.
He is making us to know or urging us to know that we should fulfill our promises before we die.
