I like this. The poem was quite wonderful. I think you should expand it though. It seems like a portion of a greater poem.
I, however, enjoyed reading this. I especially was captivated by the first six lines--so beautifully written. For the most part it was like a prose poem, whereas the poem itself is rather tear-jerking on the whole.
Loved it otherwise.

'There are things we all desire
But cannot attain" -- True enough. Interestingly though, our desires can be manifested and will be manifested in due time. We just have to wait, and not be tired by waiting. =]
