Ek Sher ki Anatomy
Taking two lines apart to see what makes them hold — misra, radif, qafiya, and the trick of the turn.
A sher is two lines. That is the whole specification. Everything else — the discipline, the centuries, the arguments — is about what those two lines are allowed to do to each other.
Kuch log kitaabon ki tarah hote hain —padh lo to poore, chhod do to adhoore.
The first line sets a debt
The first misra makes a claim that is not yet paid for. "Kuch log kitaabon ki tarah hote hain" is, on its own, a nothing sentence — the sort of thing a motivational poster says. It works only because it is a promise that the second line will be forced to keep.
The second line pays it, sideways
The trick is that the payment must arrive from an angle. If the second line merely completes the thought, you have written a sentence with a line break in it. It has to complete the thought and reveal that you were thinking about something else the whole time.
Pehla misra sawaal nahin hota. Woh sirf jagah banata hai.
Radif is the phrase repeated at the end of every second line; qafiya is the rhyme just before it. Together they build a rhythm the ear starts predicting by the third couplet. The craft then becomes about satisfying that prediction while surprising the sense.
Practical advice, for whatever it is worth: write the second line first. Most of the sher I have kept began as an ending I could not place, and then spent a week looking for something to be the ending of.
