In Zoroastrianism and Parsiism , the final saviour of the world.
He is the foremost of the three saviours who are posthumous sons of Zoroaster . He is expected to appear at the end of the last millennium of the world, miraculously conceived by a virgin who has swum in a lake where Zoroaster's seed is preserved. He will vanquish demonic power and resurrect the bodies of the dead, bestowing eternal perfection on them after all souls have been cleansed.
