1) We read in the book “On Advent and Signs of Advent” (collected by one of the friends of Sadeq Hedayat), page 47:

Major part of translations of Pahlavi texts by “Sadeq” is about the advent and the signs of advent and if we totally consider the entire Pahlavi texts of Sadeq then we should say that all of them have religious aspects.

… the issue of the advent and the signs of advent is the issue which is specially important in all major religions of the world … according to “Sadeq”: Regardless of faith which forms the basis of this hope, when, any person who is interested in the destiny of humanity and demands its spiritual perfection, becomes hopeless and sees that unfortunately the ignorant and negligent humanity is still moving toward corruption and destruction day by day and avoids the almighty God and disobey his orders more and more by having this much of amazing intellectual and scientific developments, turns to the presence of the almighty God based upon his nature and asks for his help in order to remove oppression and corruption!

Accordingly, the hope for a great universal peacemaker had been available in the hearts of all monotheists and not only this hope has record in the followers of major religions, like Zoroastrians, Jews, Christians and Muslims, but it is possible to find its signs in the ancient books of the Chinese, beliefs of Hindus, among Scandinavians and even between ancient Egyptians; also Mexican aboriginals and like them.

It should be reminded that the book “Zand va Human Yasan” and some other Zoroastrian texts, also the last two chapters of Jamasp Namag including the prediction of Zoroaster by the words of the Sage Jamasp to “Goshtasp”, king of the time who converted to religion of Zoroaster, about the Promised One of End of Days, have been translated to Persian from Pahlavi by Sadeq Hedayat, and has been published by “Hassan Ghaemian”, friend and colleague of Sadeq Hedayat, under the title of “On Advent and Signs of Advent”.
