When I was travelling on the Kosi river’s embankments in Supaul district of Bihar, which shares a border with Nepal and faces annual floods, I met octogenarian Singheswar Rai in his thatched hut. He was singing a song, which he had penned in the 80s. It talked about the devastation of the Kosi river. The concluding lines were about the hope of turning everything right one day.
