Ali_ bhai:
What is Tarveeni?
Pardon my limited knowledge on urdu poetry but I have never come across this term before...
Tarveeni is actually not even an urdu word... [can't find in dictionary].
I will make an educated guess based on finding another Tarveeni online

... Correct me if I am wrong.
Here is the Tarveeni I found half of which seems the same as posted in original post:
Samina kia pata kitni baar maray gee
maiN tau bus zindagi se darta hooN
maut tau aik bar maaray gee
-----------------
sa'b pay aati hay sa'b ki baari se
maut insaf ki alaamat hay
zindagi sa'b pay kiyoon naheen ati
So, is it ture that:
Tarveeni is term used in hindi poetry for a type of nazm that consists of two parts 3 lines each ... the first three lines discussing the specific subject matter and the last part a reflection and general thoughts on the first part related to even described in first?
