Although I never in any way actually followed Zoroastrianism, their concept of an enormous ongoing battle between a force of Good and one of Evil in the universe sounds so realistic.
The Judeo-Christian concept of God of course is that he created all, including the ability of evil to come forth within his created universe and he is the one and only God.
There are a few Zoroastrians left in small groups although they used to be dominant in Persia, now Iran.
Whether it’s Satan or “the Evil Inclination” or whatever, good people seem to attract the attention and attacks of evil forces more than ordinary people. Like a vacuum in the universe attracting particles to fill what the universe “abhors.”
Newroz is a Kurdish tradition. Not Iranian.
Some here say the Kurds were the Medes. That may be true, but the Kurds claim they are decentents of the Ezidi. (Islamists call Ezidi devil worshipers)
The celebration of Newroz is about a tradition of burning evil.
