Yima, under divine superintendence, reigned over the world for 900 years. As there was no disease or death, the population increased so that it was necessary to enlarge the earth after 300 years; Yima accomplished this with the help of a gold ring and gold-inlaid dagger he had received from Ahura Mazda, the Creator. Enlargement of the earth was necessary again after 600 years. When the population became too great after 900 years, Ahura Mazda warned Yima that destruction was coming in the form of winter, frost, and subsequent melting of the snow. He instructed Yima to build a vara, a large square enclosure, in which to keep specimens of small and large cattle, human beings, dogs, birds, red flaming fires, plants and foodstuffs, two of every kind. The men and cattle he brought in were to be the finest on earth. Within the enclosure, men passed the happiest of lives, with each year seeming like a day.
