It's a good enough book, but since it's supposed to be a simple and simplified tashreeh (according to the author), the book does use fancy words often, which are, in my opinion, considered poetic and not simple.
The author often copies and pastes explanations of other commentators. He misses out on some very important possibilities of interpretations of some shers. Sometimes they're not explained according to the complexity which the sher demands. Sometimes I'm left more confused after the explanation... kisi ko samjhane ka bhi kuch saleeqa hota hai... 🌈(or maybe it's just Ghalib and it's hard to explain him haha)
The book which I have is a hardcover with old crusty pages, some of which are misprinted, and some are glued together. But, for only 350 PKR, I can't complain.
