What did William Wordsworth imply In his poem?

This poem is actually about a girl called Lucy who is dead, and whom the poet wishes to eulogise. It does have a connection with nature in the sense that Lucy is portrayed as someone who lived close to nature - "...among the untrodden ways/Beside the springs of Dove" - and therefore had a purity and freshness about her character. The poet also compares her to two objects of nature: "a violet by a mossy stone" and "a star" to indicate her delicacy, beauty, individuality and remoteness.
