The poem carries a lot more deeper meaning than appears. It is actually a expression of the poet's joy at the return of her metaphoric lover. She has compared this happiness of her with many thing that portray beauty and love. The first stanza is a description of her mental state, the happiness that has overwhelmed her. However, the second stanza adopts a more practical tone, when she says how to welcome her love. In the first stanza, she has turned to nature for her descriptions, since its the most basic that can be percieved. In the second stanza, she turns to man-madd riches to decorate and welcome her lover.
BTW: any comments or criticisms are welcomed and appreciated ;-)
The first stanza consists of transient images- images of things that will not last forever. Thus she says that the future of love is unpredictable, and yet her love is as sweet as a singing bird and apple trees etc. Also, the images of the first stanza suggest abundance, freedom, peace and calm, all of which are associated with love.
In the second stanza, she celebrates her love. There are numerous examples of royal and exotic imagery. For example, pomogranates are exotic fruits, and the colour purple, as well as the fleurs-de-lys are symbolic of royalty. Also, the images of the second stanza greatly contrast those of the first stanza. The second stanza is a description of a large dias( a permanant structure.) Another contrast is that the frist stanza has all simple images of nature, while the second stanza has images of man-made richness.
