Why dove?

[Tiger the Lion]

O why dove, why dove, sit alone in your vast fright?
While the blackness swells to swarm on this very night!
Fly dove, fly dove, give the world your shimmering light!
With feathers of white, oh how they glisten so bright!
Please dove, please dove, start before it grips tight!
Pulling us down, with the untold darkest of might!
I cry dove, cry dove, will you not hear my plight?
Your great radiance beside, we could put up a fight!
Rise dove, rise dove, the world you shall incite!
Your illumination beaming, the black will ignite!
Please dove, please dove, smother the darkest blight!
Raise up and take flight, as a gleaming white knight!
So why dove? Why dove? Why sit alone... in vast fright?

Hello and welcome SS. You have sacrificed any hope of conveying meaning all for one rhyme. Why? Anyone can google "rhymes with fright" and write out 13 loosely related lines. My advice would be, as an exercise, rewrite each line saying what you MEAN, without regard for rhyme. You may or may not get something from that. Also, IMO exclamation marks are for facebook, they make for ugly graffiti in poetry, almost all of the time.
Thanks for the post and good luck!!!!!!
