"Zoroastrians believe that an individual, called the “Saoshyant,” will usher in this era and lead the battle against Angra Mainyu. The Saoshyant is a savior-figure who will be born of a virgin, which the text calls “Gobakabu”. The text talks about her lineage and how she is a descendant of certain individuals. This is important for Zoroastrians because they believe that the Saoshyant will be a descendant of Zarathustra, the original prophet of Zoroastrianism. This text tells the story of how she will bathe in a lake and become impregnated with the seed of Zarathustra, which has been kept intact for thousands of years by angels. Then she will give birth to the Saoshyant."

"The Saoshyant is a future liberator or messiah who, according to Zoroastrian belief, will come to the world at the end of time to restore cosmic order, defeat evil, and renew creation. This figure will be born of a virgin and will perform a series of heroic and purifying acts to lead humanity into an era of peace, justice, and prosperity.
The association of the Saoshyant with the end of the world lies in the belief that his arrival will mark the end of the battle between the forces of good and evil and the transformation of the existing reality. According to some Zoroastrian interpreters, it is believed that his coming will be accompanied by significant cosmic events, such as the resurrection of the dead, the final judgment, and the total renewal of the universe."

"Zoroastrian tradition envisions three future saviours, one for the end of each 1,000-year period that comprise the last 3,000 years of the world. All three will be born of maidens, conceived while their mothers bathed in a lake that miraculously preserved the seed of the prophet Zoroaster himself. The first will be named Hushedar, the second Hushedarmah, and the third will be Saoshyant, who will lead humanity in the final battle against falsehood."
