Also, this is not a Bollywood song. It is a poem by a 17th/18th century Punjabi Sufi Muslim poet Bulleh Shah performed here by a Punjabi Sikh called "Rabbi" with scenes from Hindu majority India in the background and English subtitles.

So many identities :)

Well, Rumi is the best-selling poet in the United States. Rightly so, too: the Sufi poets are as great as any poetry ever written, I think, and can be astonishingly modern. That being said, I have the impression that they are distinctly non grata in the vast majority of the Muslim world. No?
