The usage of metaphors in the form of cassette is really beautiful, i do believe and even i can feel that you are talking about human's life, how it is progressing and going ...

Stretching out my wings
I become a crystal parabola
Painted in mauve and violet.
Folding my wings, an avian flux
Disintegrating mercurial,
Handful of gravel tossed
Into the sun.

Thank you so very much for the wonderful theme @d-pend :)
