He was son of Mathura Das Kamboh and belonged to Multan which was a great center of learning during Mughal reign.
"One day in the reign of the Emperor Shah Jahan, Har Karan Kamboh had sat at the seat of Empire in the city of Matura (Mathura) in the company of his agreeable companions and chosen friends and devoted himself to improving his skills as Munshi (Secretary)".
Insha-i-Har Karan is divided into seven sections and contains models of letters and other documents relating to the State.
Not much is known about his other works but Insha-i- Har Karan was indeed considered an excellent book till British rule.
In the beginning of his book, Har Karan introduces himself as “the ignorant lowly pauper, the weakest servant of the eternal God, Har Karan, son of Mathuradas Kamboh from Multan” (Faqir-i haqir-i hechmadan, azhaf min ibad Allah As-Samad, Har Karan Valad-i Mathuradas Kamboh Multani).
