Zoroastrian eschatology is about the end of the world for the Zoroastrian religion. It talks about what will happen when the world comes to an end, how it will happen, and what people need to do to prepare.
Imagine you are playing a game and you reach its end. Similarly, Zoroastrian eschatology talks about the game of life and what will happen when it is over.
According to Zoroastrian eschatology, there will be a final battle between the forces of good and evil. This battle is between Ahura Mazda, the god of light and goodness, and Angra Mainyu, the god of darkness and evil. It will be a very big and powerful battle with many struggles.
Ahura Mazda will win this battle with the help of his followers, the good people of the world. Those who have been good and kind during their lives will go to a happy place where they will be rewarded and live forever. However, those who have been evil will go to a terrible place where they will be punished for all their bad deeds.
The world will then be renewed, and all the bad things will be gone. The world will be perfect and people will live happily in it. This is called the Frashokereti, which means "making wonderful" or "making excellent."
Overall, Zoroastrian eschatology is a belief about how the end of the world will happen. It talks about a big battle between good and evil, and how good will eventually win. After this, a new world will emerge, a perfect world where people will live happily ever after.
