One possible theme could be self - expression. If'meri awaz' (my voice) is central to the story, it might be about a character finally being able to express themselves fully when they find 'roshni' (light).
I haven't come across the 'khene ko humsafar hain' full story. It might be a story from a particular culture or community that I haven't had exposure to yet. Maybe you can check local libraries or cultural centers related to the origin of this title for the full story.
I'm sorry, I'm not familiar with the specific story named'meri awaz ko mil gayi roshni'. It could be a story from a particular regional literature, a local folktale or something else. Maybe you can try to find more information from local libraries or relevant cultural institutions.
I'm not entirely sure as I'm not familiar with this specific novel. It could potentially be about a transformation where someone or something becomes the heartbeat (dil ki dharkan). Maybe it's a love story where a character comes to represent the very essence of another's heart.
Since I'm not familiar with the 'dil ki nazar se khoobsurat' story, it could be about seeing beauty through the eyes of the heart. Maybe it's a story of a person who discovers the true beauty in others or things that are often overlooked by the ordinary eye, but this is just speculation.
I haven't read the 'dil pardesi ho gaya story'. However, generally speaking, if 'dil' represents the heart or emotions, and 'pardesi' means foreign or alien, it might be a story about a shift in one's feelings to something or someone that was once familiar but now seems distant, perhaps due to a change in circumstances, a relationship turning sour, or personal growth in a different direction.
Honestly, I have no clear idea. It could potentially be a poetic or metaphorical expression, but without further clarification, it's hard to say for sure.
