This book, although it gives a somewhat vague idea of ​ ​ Zoroastrianism itself, but as a primary approximation to it, as a concept of a code of honor, as the doctrine of light and darkness and the rules of human behavior in life is a very good initial guide to this ancient doctrine, although, of course, she cannot claim depth and sacraments, but this is due to the forced limited information about the subject and ignorance of the author.
