Bundahishn
On [the spiritual chieftainship of the regions of the earth] it says in revelation, that every one of those six chieftainships has one spiritual chief; as the chief of Arzah is Ashâshagahad-ê Hvandkan, the chief of Savah is Hoazarôdathhri-hanâ Parêstyarô, the chief of Fradadafsh is Spitôid-i Aûspôsinân, [the chief of Vidadafsh is Airiz-râsp Auspôsinân,] the chief of Vôrûbarst is Huvâsp, the chief of Vôrugarst is Kakhravâk.
Zaratust is spiritual chief of the region of Khvantras, and also of all the regions; he is chief of the world of the righteous, and it is said that the whole religion was received by them from Zaratust.
In the region of Khvaniras are many places, from which, in this evil time of violent struggling with the adversary, a passage (vidarg) is constructed by the power of the spiritual world (mainôkih), and one calls them the beaten tracks of Khvantras.
Counterparts of those other regions are such places as Kangdez, the land of Saukavastân, the plain of the Arabs (Tâzîkân), the plain of Pêsyânsal, the river Nâîvtâk, Airân-vêg, the enclosure (var) formed by Yim, and Kasmir in India.
And one immortal chief acts in the government of each of them; as it says, that Pêshyôtant' son of Vistâsp, whom they call Kitrô-main, is in the country of Kangdez; Aghrêrad son of Pashang is in the land of Saukavastân, and they call him Gôpatshah; Parsadgâ' Hvembya is in the plain of Pêsyânsaf, and he is Hvembya for this reason, because they brought him up in a hvemb (jar') for fear of Khashm ('Wrath'); [Asâm-i 2 Yamâhust is in the place which they call the River Nâtvtâk]; the tree opposed to harm is in Airân-veg; Urvatadson of Zaratust is in the enclosure formed by Yim.
Regarding them it says, they are those who are immortal, as are Narsih son of Vivanghân, Tus son of Nôdar, Giw son of Gudarz, Ibairaz the causer of strife, and Ashavazd son of Pourudhâkhst; and they will all " come forth, to the nar assistance of Sôshyans, on the production of the renovation of the universe.
Regarding Sâm' it says, that he became immortal, but owing to his disregard of the Mazdayasnian religion, a Tûrk whom they call Nihâg wounded him with an arrow, when he was asleep there, in the plain of Pêsyânsaf; and it had brought upon him the unnatural lethargy (bushasp) which overcame him in the midst of the heat.
And the glory (far) of heaven stands over him for the purpose that, when Az-i Dahâk becomes unfettered (arazak), he may arise and slay him; and a myriad guardian spirits of the righteous are as a protection to him.
Of Dahâk, whom they call Bêvarâsp, this, too, it says, that Frêdûn when he captured Dahâk was not able to kill him, and afterwards confined him in Mount Dimâvand; when he becomes unfettered, Sâm arises, and smites and slays him.
As to Kangdez, it is in the direction of the east, at many leagues from the bed (var) of the wide-formed ocean towards that side.
The plain of Pêsyânsaf is in Kâvulistân, as it says, that the most remarkable upland (bâlist) in Kâvulistân is where Pêsyânsaf is; there it is hotter, on the more lofty elevations there is no heat.
Afrân-veg is in the direction of Âtarô-pâtakân.
The land of Saukavastân is on the way from Türkistan to Kinistân, in the direction of the north.
[The enclosure] 3 formed by Yim is in the middle of Pârs, in Sruvâ; thus, they say, that what Yim formed (Yim-kard) is below Mount Yimakân. is in Hindustân.
