Frawardigan is a ten-day period at the end of the Zoroastrian religious year during which the souls of the dead are commemorated. The name frawardigan is a Zoroastrian Middle Persian allusion to the fravashis, which—among other aspects —also include the souls of the dead. A festival during which the immortal souls and the guardian spirits of departed ancestors, come down into the temple. Many Zoroastrians take time off to pray, and eat sacred food.
