Analysis of "Bright Star" by John Keats

Bright star, would I were stedfast as thou art--
Not in lone splendour hung aloft the night
And watching, with eternal lids apart,
Like nature's patient, sleepless Eremite,
The moving waters at their priestlike task
Of pure ablution round earth's human shores,
Or gazing on the new soft-fallen mask
Of snow upon the mountains and the moors--
No--yet still stedfast, still unchangeable,
Pillow'd upon my fair love's ripening breast,
To feel for ever its soft fall and swell,
Awake for ever in a sweet unrest,
Still, still to hear her tender-taken breath,
And so live ever--or else swoon to death.

       In this poem, the speaker is talking to a star. I know, it sounds really weird but in poetry you can basically get away with many things. This poem talks about eternity and refers to the north star, because the north star never moves and remains in the same place forever. The reason why the star is so important to the speaker is because of its everlasting position and shine. Later on in the poem, it is clear that the speaker does not want just any old eternity; especially not the eternity that a north star has (floating in the sky above the north pole), but he wants to spend an eternity pressing his head against his girlfriend's chest and spending an eternity with her. It says that if he can't have that, he will live another eternity: the eternity of death.
        I think this poem is naive to a certain extent. I respect the fact that he wants some things to last forever, but realistically speaking nothing lasts forever. There are many things that last for a long time, but for something to last forever would be impossible. I also feel cautious for the speaker, if he is so in love with his girlfriend, I wonder if his girlfriend would take advantage of that and use him as a tool. Although love has no boundaries, if someone loves someone very much, and the individual does not love him/her as much, then bad things can occur in the relationship.
        Wanting something to last forever is fine, but one has to be careful on what one wants to last forever. Some choices may give great fortune, but some may bring eternal suffering. It all comes down to make the right choice.
