Khshathra Vairya (Avestan, "Desirable Dominion" or "Kingdom to be Chosen"; Middle Persian Shahrewar) is one of the six Amesha Spentas of Zoroastrianism. He personifies the rightful power and kingdom of Ahura Mazda, is the guardian of metals and, in older thought, of the sky, and gives his name to the Iranian month Shahrivar.

Name and meaning
The Avestan xshathra means "power, rule, dominion, kingdom," and is related to Sanskrit kshatra, the word behind the Indian warrior class of Kshatriyas. Vairya means "desirable" or "to be chosen." The name therefore points to the ideal rule of Ahura Mazda, a dominion that human beings should desire and choose, in contrast to tyranny. The spelling in this entry's address, "khsathra," is one of several English transliterations.
In Middle Persian the name became Shahrewar, and in modern Persian Shahrivar. Zoroastrians today often use these forms in prayer and in the calendar.
From Gathic concept to divine being
In the Gathas of Zoroaster, xshathra is an important idea: the power that belongs to Ahura Mazda, which the righteous hope to share and which will be fully established at the renewal of the world. Scholars debate how far the Gathas already treat it as a distinct divine figure. In the Younger Avesta, Khshathra Vairya appears clearly as a personal being and is usually listed third among the Amesha Spentas, after Vohu Manah and Asha Vahishta.
Later Zoroastrian tradition connects Shahrewar with just and benevolent rule and with care for the poor and weak, seeing right use of power as a religious duty.
Guardian of metals and the sky
Each Amesha Spenta protects one of the seven creations, and Khshathra Vairya is the guardian of metals. The association appears to have developed over time. Scholars such as Mary Boyce linked it to an ancient Iranian idea that the sky was a vault of stone; as the stone sky came to be imagined as metal, and as metal tools and weapons became symbols of power, the guardian of the sky became the lord of metals.
In Middle Persian literature, metal is sometimes simply called by his name, and gold and silver are counted among his gifts. Treating metals honestly and keeping them clean is regarded as honoring him.
Calendar, symbols and adversary
In the Zoroastrian calendar the fourth day of every month is named Shahrewar, and the sixth month of the year is dedicated to him; the month Shahrivar survives in the modern Iranian solar calendar. When the day and month names coincide, a traditional name-day festival is celebrated. His flower is the royal basil.
Middle Persian texts oppose him with the demon Saurva (Sawul), who embodies evil rule, oppression and misgovernment. This pairing expresses the Zoroastrian conviction that power itself is not evil but can be seized by the forces of Druj, the Lie, when exercised unjustly.
Role at the end of time
Zoroastrian eschatology gives metals a dramatic role. At the final renovation of the world, Frashokereti, the metals in the mountains will melt and flow over the earth as a river of molten metal. All humanity will pass through it: to the righteous it will feel like warm milk, while the wicked will be purified by it. Tradition connects this ordeal with Shahrewar as lord of metals.
The end of this process is the full establishment of the desirable kingdom of Ahura Mazda, the perfect rule that Khshathra Vairya represents. The future savior Saoshyant presides over the renewal, when evil is defeated and the good creation is restored.
Related beings and spellings
Khshathra Vairya is closely linked with the other members of the Heptad. In lists of the Amesha Spentas he follows Asha Vahishta and precedes Spenta Armaiti, guardian of the earth; the "dominion" of the sky and the "devotion" of the earth are sometimes seen as a complementary pair. In the calendar, certain yazatas, including Mithra and the sky-being Asman, are counted among his helpers.
Common spellings include Khshathra Vairya, Xshathra Vairya, Kshathra Vairya and Khsathra Vairya in Avestan transliteration, Shahrewar or Shahrevar in Middle Persian, and Shahrivar in modern Persian.
Because the name contains the word for rule, Khshathra Vairya has also been discussed by historians of ancient Iran in connection with ideas of kingship. The Achaemenid and Sasanian rulers presented their authority as granted by Ahura Mazda, and Zoroastrian writers used the ideal of Shahrewar to judge whether a king ruled justly or oppressively. The concept thus joined religious devotion with political ethics.
