The opening lines of this song were reportedly from a letter Jaikishan wrote to his fiance in Gujarati.[MR6]
Jaikishan revealed in a Filmfare article that he had composed this popular song by himself. Shankar was unhappy about this since it breached their agreement to not reveal to the public their individual contribution to a song. The duo's relationship was already strained due to Shankar's inclination to use Sharda instead of Lata Mangeshkar for his songs. This article deepened their rift further.[MR15]
