Doubt Dispelling Explanation is a Sanskrit reading of Skend Gumanig wizar chapters 13th and 14th along with explanations of the linguistic peculiarities. Skend Gumanig wizar is a Zoroastrian apologetic book written by Mardan Farrox in the ninth century. The book carries eloquent issues and has been translated into English by E. W. West in 1882. In the opening pages of the book the author declares that I, Mardan Farrox Ohrmazd dad, wrote this book, having noticed on many occasions the variety of the cults, religions and teachings. And, since I was young, I sought and examined the truth: that is the reason of my voyages to the lands overseas.
