How we love to see a rainbow! Something about them inspires a feeling of hope and joy. Perhaps it is because the rainbow reveals something normally beyond our perception - the colours of the spectrum. The colours are all around us all the time, but normally we can't see them. It's easy to get lost in the material world of substance - but the sight of a rainbow reminds us there is something more.
There is light to lift this mourning,
Each clear ray a spectrum of colours
that I cannot see;
But I know they are there,
just as you exist
Like a rainbow on a far horizon.
