Mainyo-i-Khard 55

The sage asked the spirit of wisdom

thus: 'Wherefore are these mountains and rivers made, which are in the world?'

The spirit of wisdom answered

thus: 'Of these mountains, which are in the world, there are some which are moderators of the wind, and there are some which are warders off;

there are some which are the place and vent, the resting-place and support of the rainy cloud;

and there are some which are smiters of Aharman and the demons, and maintainers and vivifiers of the creatures and creation of Aûharmazd, the lord.

And these rivers, which are in the world, the creator Aûharmazd has formed, from the borders of Albûrz, for providing the protection and for the vivification of his own creatures and creation.'
