Since I'm not familiar with the 'khatna story' concept, I can't provide a particular story. But generally, a great story often has interesting characters, a captivating plot, and a meaningful message. Maybe a 'khatna story' with these elements would be considered the best. For example, a story about a young person from the 'khatna' community who overcomes great difficulties to achieve something great for their people.
I'm afraid I can't share a 'best khatna story' without more information. However, if we assume that a 'khatna story' is like other traditional stories, it might involve elements like love, sacrifice, and discovery. A story where a character in the 'khatna' world sacrifices their own desires for the greater good of their community could be a really good one. It could also be a story of a journey, either physical or spiritual, that a 'khatna' character undertakes and through which they learn important life lessons.
Sorry, I don't have a specific 'best khatna story' to share as I don't know enough about what a 'khatna story' actually is.
