Ostensibly a song in which a bride laments about her separation from her parents, this song is actually about separation from one's homeland. It was written by Nawab Wajid Ali Shah of Awadh when the British exiled him to Calcutta from his kingdom in Lucknow.
This was the second of Basu Bhattacharya's trilogy of films which told stories of marital discord in modern, urban families. The other films in the trilogy were "Anubhav" (1971) and "Griha Pravesh" (1979). All three films had music by Kanu Roy. Ironically, for someone who depicted marital life with great sensitivity, Basu Bhattacharya himself had a tumultuous married life. He married Rinki Bhattacharya, the daughter of his mentor, director Bimal Roy, in 1961 against the wishes of Roy. After years of abuse, Rinki left Basu Bhattacharya in 1982 and went on to make documentaries and write extensively on the topic of domestic violence. The couple got formally divorced in 1990.
