1. can't we express the dard and feelings of love and tragedy in eachlines? Is it necessary that every line should contain different mening? There is no rule regarding this. It's OPTIONAL. Traditionally, ghazal has been polythematic. However, these days more and more monothematic ghazals are appearing these days. Even when it is polythematic, one can feel some kind of coherence/unity among the shers by their tone/mood/style etc. In any case, as I said there is no rule to follow on this. When you write a mono-thematic (on a single theme like you did above) ghazal, care should be taken to keep shers from becoming REDUNDANT. If two shers are saying exactly the same thing, you better present only one of them and discard the other. Redundant shers makes a poor ghazal. New sher necessarily should say something new, something different. It does not have to be completely different. But it should not be REDUNDANT either. How to keep that balance is upto you. 2. Is it necessary and feasible to make gazal in a staraight jacket formula?sometimes there may not be proper words in nepali?How do u fill the vaccum? If you don't have proper words, you don't have ghazal. That's the weakness of ghazal genre of poetry. So you should be very careful to choose काफिया and रदिफ in your मत्ला. I have talked about this in some detail in one of Shirish' threads. It might be helpful. - http://www.sajha.com/sajha/html/openthread.cfm?forum=2&ThreadID=22040&show=all
