I'm sorry, I'm not familiar with the specific 'ek thi rani ek tha ravan' story. It could be a relatively unknown or regional story. Maybe it's about a queen and a demon - like character, but without more context, it's hard to tell the full story.
A third possible theme could be about self - discovery. Through her encounters with the ravan, the rani may learn more about herself, her capabilities, and her place in the world. Also, there could be a theme of sacrifice, where she might have to give up something important in order to overcome the ravan or protect her people.
I'm sorry, I'm not very familiar with the specific story named 'ek haseena thi ek deewana tha'. It could be a story from a particular movie, book or regional folklore. Maybe it's about a beautiful woman (ek haseena) and a passionate lover (ek deewana). But without more context, it's hard to tell the full story.
It could be that the 'haseena' has some sort of mystery around her. And the 'deewana' is drawn to this mystery as much as her beauty. The main plot would then be the deewana trying to unravel the mystery while also winning her heart.
I'm sorry, I'm not very familiar with the specific 'ek hasina thi' story. It might be a story from a particular region, culture or media that I don't have enough information about.
I'm not entirely sure which specific 'ek thi begum real story' you are referring to. There could be many stories with such a title. It could be about a particular woman in a certain historical or cultural context, but without more details, it's hard to tell the full story.
