What does lovely, dark and deep suggest? What is the underlying significance in the repetition of the last two lines of the extract? Mention the moral tag that the poet attaches to the poem.
The poet finds the woods to be beautiful and charming. The woods appear to be restful, seductive and lovely to the poet. When taken at a symbolic level, the woods are opposed to the promises which the poet must keep. Woods represent sensuous enjoyment (lovely), the darkness of ignorance (dark) as well as the dark inner self of man (deep).
The last two lines mean that the poet Robert Frost has to fulfill his promises and has to travel a lot of distance before he can rest. Sleep could also be interpreted as a metaphor for death.
Poet attaches the moral tag that in life one must do one's duty and carry out one's obligations.
