Bashvan

Bashvan (also spelled Baishvan or Vaishvan) is a term primarily associated with Zoroastrian eschatology. It refers to the final battle, or a series of battles, between good and evil at the end of time. This cosmic struggle culminates in the ultimate victory of Ahura Mazda (the supreme God) over Angra Mainyu (the destructive spirit).

In Zoroastrian belief, Bashvan represents the final stage of the world's redemption and restoration (Frashokereti). It is a time of great turmoil and suffering, but also a time when the righteous will be tested and ultimately rewarded. The forces of good, led by the Saoshyant (a future savior figure), will vanquish the forces of evil, purifying the world and ushering in an era of eternal peace and perfection.

The details and specific events associated with Bashvan vary across different Zoroastrian texts and traditions. Some accounts emphasize the physical battles and cosmic upheavals, while others focus on the moral and spiritual aspects of the struggle. The concept is central to Zoroastrian views of history and the ultimate destiny of humanity.
