Convent Threshold

I believe Rosetti uses a lot of things, places and scenes as a symbol of a love she wishes could be " I seek the sea of glass and fire" The words "sea of glass" tell me she wants this clear "glass" purity in their relationship that anyone can see through it  and be pleased like god we know this as she refers to what they did presumably sex as "sin" which is biblically related and a very stong term for wrong doing. She also uses the word "sea" which I feel is very significant as it highlights a vastness nevery ending and "fire" known to passion  and strong love. It's almost as if she wants to use this as a renewal to her "selfsame stain"longing for this purity. We really see how the protagonist in this poem is  battling between her love and where she wants to be "steps in heaven alone". She also seems as if she wants to show her lover that she knows what it's like to see the beauty of earth as she uses a question and then answers it herself "You looking earthward, what see you?" and describes some beauty to the earth "Milk white" but then she goes on to say "most glad, most made stong with wines" the fact she repeats "most" gighlights their are a certain few who don't see things this way she saw it like that to describe it but now she sees the "far off city- grand" and begins to see the world for what it is only being made strong by "wine" something  tempoary where young men and women come and  go and again this tempoary thing, compared to when she describes "paradise" "the righteous sup" not most but "the" and instead of the tempoary "come and go" they wake to sing a "cadenced hymn" A hymn being a worship to god but on earth "love- music" this again highlights her mind is set in two places. The fact that the comparisons are set above eachother mimicing the lines but in a different way really shows that its these things she is fighting through.
