Analysis of Flower that bloomed once

Would some doors remain locked forever
Would these locks remain dark forever

What should I say of phoenix's noble passion
Once burnt it becomes not ashes forever

Leave myths and come to that corner with me
Where flowers that bloom once die forever

And asses trample over that dusty ground
Where Sultan of golden Hind sleeps forever

Here ends the manuscript and lo!
Bullbla will not keep babbling forever.
