Yima, the first man and progenitor of the human race, being advised by Ahura Mazda, built a vara, a walled enclosure in the far north, to hold there the best and fairest of men, animals and plants to preserve them from a great and terrible winter so that he could repeople the world at the end.

"Thither thou shalt bring the seeds of men and women, of the greatest, best, and finest kinds on this earth; thither thou shalt bring the seeds of every kind of cattle, of the greatest, best, and finest kinds on this earth.
...
There shall be no humpbacked, none bulged forward there; no impotent, no lunatic; no poverty, no lying; no meanness, no jealousy; no decayed tooth, no leprous to be confined, nor any of the brands wherewith Angra Mainyu stamps the bodies of mortals."

"That Vara he sealed up with the golden ring, and he made a door, and a window self-shining within.
O Maker of the material world, thou Holy One! What lights are there to give light in the Vara which Yima made?
Ahura Mazda answered: ‘There are uncreated lights and created lights. There the stars, the moon, and the sun are only once (a year) seen to rise and set, and a year seems only as a day."
