रौशनी अपनी उमंगों की

Documented in full as 'Roshni Apni Umangon Ki Luta Kar Chal Diye', this is among the most cited Noor Jehan solos of Nadaan (1943), with lyrics by Zia Sarhadi and music by Datta Korgaonkar. Its title image — giving away the light of one's own joys — captures the film's romantic melancholy.

Korgaonkar keeps the setting hushed and slow, an unhurried melodic line over restrained accompaniment that gives Noor Jehan room for the long, expressive sustains and delicate ornamentation that defined her early style.

Zia Sarhadi's lyric uses 'roshni' (light) as a classical Urdu metaphor for the luminosity of aspiration, hope, and vitality — and then gives it away: the full line 'Roshni Apni Umangon Ki Luta Kar Chal Diye' (Having spent the light of my aspirations, they walked away) turns a positive image (light) into a record of expenditure. The beloved has not merely departed; they have taken the speaker's inner illumination with them. This is a sophisticated lyric move: the loss is not described as darkness but as the prior burning-away of all one's brightness in the act of loving. The past-tense 'luta kar' (having spent, having squandered) signals that the loss is complete — a classical ghazal topos where the beloved's departure is a kind of spiritual emptying. Datta Korgaonkar's unhurried, internally focused musical setting — melodic line sustained over minimal accompaniment — gives Noor Jehan room to make each word audible, her voice dwelling on the sustained tones where the lyric's grief is concentrated.

Like 'Ab To Nahin Duniya Mein' from the same film, 'Roshni Apni Umangon Ki' is a Noor Jehan solo from Nadaan (1943), directed by Zia Sarhadi, who also wrote the lyrics. The full documented title — 'Roshni Apni Umangon Ki Luta Kar Chal Diye' — distinguishes it from the more commonly abbreviated form. The song is among the most cited of the film's seven Noor Jehan solos, and music historians who have written on the 1943 Hindi film song landscape regularly include it when assessing the depth of Datta Korgaonkar's compositions for Nadaan. The bittersweet, resigned emotional register of this song provides a counterpoint within the Nadaan soundtrack to the more acutely painful mourning of 'Ab To Nahin Duniya Mein.' Together, the two solos show the range of Zia Sarhadi's lyric writing: from blunt loss to the more philosophically resigned accounting of a life spent in love.

Noor Jehan's body of work from 1943 — including her Nadaan songs — represents a formative chapter in the history of Hindi film song, one that became inaccessible to Indian audiences after her 1947 migration to Pakistan. These recordings were preserved by collectors on both sides of the border and have been progressively digitized for archival platforms. 'Roshni Apni Umangon Ki' in particular is discussed in the context of the 1940s female solo tradition: the emotional register of resigned bittersweet loss that Noor Jehan embodied influenced later playback singers who studied her technique. Radio archives at All India Radio still hold recordings of her 1943-era songs as pre-Partition heritage material. The song is also cited in the scholarly work on Zia Sarhadi's career as a writer-director — a dual role unusual for the 1940s Hindi film industry.
