Given my lack of knowledge about Atish Fishan's Urdu novels, it's challenging to define the main themes. Generally in Urdu literature, themes such as the struggle for identity, the importance of morality, and the power of emotions are prevalent, and there's a possibility that his novels also incorporate these in some way.
Since I'm not acquainted with this novel, it's hard to determine the exact theme. But considering the words 'ishq' (love), 'junoon' (passion) and'sakoon' (peace), it might be about how love can involve passion and also lead to a sense of peace. Maybe it shows a journey of love through different emotional states.
I'm not familiar with 'ishq junoon ishq sakoon complete novel'. However, you could ask in some literature - focused forums or groups where people might be able to give you more information about it, like its plot, characters, and writing style.
Unfortunately, without more in - depth knowledge of Atish Fishan's Urdu novels, it's hard to recommend his works directly. However, you could look for reviews and discussions on Urdu literature platforms which might lead you to his notable novels.
It's hard to say. You might need to do some research or look for reviews and comments from people who are familiar with it to find out if it's based on a novel.
Ishq is an Urdu word often associated with intense love or passion. 'Ishq not a love story' could imply that the kind of love or passion represented by ishq is different from what we typically consider a traditional love story. Maybe it's a more complex, unromanticized view of love.
I'm not sure specifically what the 'Ishq Murshid' is. It could be a very specific story from a particular culture or a work that is not widely known. Without more context, it's difficult to say what the ending story is.
