Pinky, thank you for the lyrics of this wonderful song, I remember BC, this is one of your favorites too
Reeth,
I am afraid you got the story wrong... This is no ghost story...

. But I agree with you the picturization is wonderful. The story and the ensuing situation are much more powerful than that. Dev and Usha Kiran are in love and she is raped by s'one. (They sing that gorgeous Hemant Lata duet right at the beginning of the movie, "Yaad kiya dil ne kahan ho tum"

). She runs away and gives birth to a child and then returns,
where, she realises that Dev is waiting for her and the rest of the story is how they come to terms with the tragedy and how Dev tries to heal her wounds. The song emerges out of this situation.
Considering the kind of double standards Hindi films have, especially when it comes to rape, this movie is a gem. First of all, rape is usually relegated to an incident that happens to the sister of the hero, who promptly waves a bottle of poison and conveniently dies. The hero then swears eternal vengeance and the movie often spins off into revenge drama.The social stigma and the issues emerging out of rape are thus made symbolic and get diverted into a question of honor, often male honor. (I can think of many Amitabh Bachchan/Vinod Khanna/Shatrughan Sinha films that used this plot.) A variation of this would be some c grade films where the victim does the revenge turn (I think Dimple did this for a film called Ghayal Sherni or some such), the focus is really on sensational violence where the social ramifications and the widespread prevalence of rape get diverted and localised into impossible or fantastic actions.
Here are some other resolutions that Hindi films offer if it does happen to the heroines:
Roti Kapda aur Makan: Moushami is raped by three men and has a child. Just before the movie ends, when it is assumed she will marry Manoj Kumar, the child is killed off in the skirmish between the hero and the villains and here's how her well-meaning father consoles her: "Jane do ...jo hua accha hua, paap ka bojha tha..." (something along these lines).
Rajput: Vinod Khanna and Ranjeeta are in love and she is raped by Ranjeet who is married and has a daughter as old as Ranjeeta. Ranjeeta disappears and has the child. When Vinod Khanna finds her she tries to run away from him saying she is "not Kabil" enough for him as she is no longer pure. Guess how Vinod Khanna resolves the situation: He hunts out Ranjeet and gets his girlfriend married to him. Honor, you see, is vindicated. The story becomes even more vulgar after this. Vinod then, under the eyes of a smiling/sad Ranjeeta then falls for Tina, the daughter of Ranjeet.
Apart from Ghar, Insaaf Ka Tarazu and Patita, I have not seen many films in mainstream Bollywood that deal with rape with any degree of sensitivity or any sense of reality for that matter.
A piece of enriching reading.
of Hindi cinema. Not many are able to make out accurate readings.
