Nana, This piece is really well written, there are some awesome lines within the piece and it felt slightly melancholic with some of the expressions, it seems to me that your thoughts are pondering on a subject that you cannot understand,
The title seems a little long but that's just my opinion, it might work better shorter, maybe "why are all the rainbows gone?", once you read the poem you get the full question anyway, but again just my personal thought on it.

Lovely piece, sweets

The last time I went on retreat on the way back home there was a rainbow in the sky.When the sunlight hits the natural prism formed by clear drops of rain we see a beauty connecting heaven to earth . Kind of like you sunshine
Thank you for writing this
Makes me think of a spiritual song from mercy me
