In this picture it resembles a shaft of light from a torch.......rainbow colored light emanating from a heavenly torch.
I rememberd a story I had read in my English texts when I was 7. It is firlmy etched, every word alongwith the pictorial depiction. A weeping sky looking towards the Earth, the two connected with a rainbow. I looked at U and said do you the know the sky is weeping? U listens, I think, because he doesn't say a word. Or maybe he just concentrates on the traffic happy that I entertain myself. It is missing its Earth. They were much in love and wanted to get married. But people on Earth felt they would have nowhere to go if the Earth and the Sky got married. Hence they schemed and plotted and the union of Earth and Sky was prevented. Each time we see a rainbow in the sky, it is the garland the Sky hurls towards the Earth. The garland he could not adorn his Earth with.
I have never stopped feeling guilty for being one of the "Earthlings"!
