Zoroastrianism (Persian: دین زرتشتی Dīn-e Zartoshtī), also called Mazdayasnā (Avestan: 𐬨𐬀𐬰𐬛𐬀𐬌𐬌𐬀𐬯𐬥𐬀) or Beh-dīn (بهدین), is an Iranian religion centred on the Avesta and the teachings of Zarathushtra Spitama, who is more commonly referred to by the name Zoroaster (Greek: Ζωροάστρις Zōroastris).Among the world's oldest organized faiths, its adherents exalt an uncreated, benevolent, and all-wise deity known as Ahura Mazda (𐬀𐬵𐬎𐬭𐬋 𐬨𐬀𐬰𐬛𐬃), who is hailed as the supreme being of the universe.[26] Jonathan P. Berkey argues that[clarification needed] In the 19th century, through contact with Western academics and missionaries, Zoroastrianism experienced a massive theological change that still affects it today.[32] According to scholars, Ahura Mazda is an uncreated, omniscient, omnipotent and benevolent God who has created the spiritual and material existences out of infinite light, and maintains the cosmic law of Asha.[37] Yazatas are further divided into Amesha Spentas, their "ham-kar" or "Collaborators" who are Lower Ranking divinities,[41] and also certain healing plants, primordial creatures, the fravashis of the dead, and certain prayers that are themselves considered holy.The Amesha Spentas and their "ham-kar" or "collaborator" Yazatas are as follows: In Zoroastrianism, Ahura Mazda is the beginning and the end, the creator of everything that can and cannot be seen, the eternal and uncreated, the all-good and source of Asha.[43] Traditionally, the manthras (similar to the Hindu sacred utterance mantra) prayer formulas, are believed to be of immense power and the vehicles of Asha and creation used to maintain good and fight evil.For these, asha was the course of everything observable—the motion of the planets and astral bodies; the progression of the seasons; and the pattern of daily nomadic herdsman life, governed by regular metronomic events such as sunrise and sunset, and was strengthened through truth-telling and following the Threefold Path.[58] Zoroastrianism is not entirely uniform in theological and philosophical thought, especially with historical and modern influences having a significant impact on individual and local beliefs, practices, values, and vocabulary, sometimes merging with tradition and in other cases displacing it.[52] While Ahura Mazda created the universe and humankind, Angra Mainyu, whose very nature is to destroy, miscreated demons, evil daevas, and noxious creatures (khrafstar) such as snakes, ants, and flies.[65] Ahura Mazda will ultimately prevail over the evil Angra Mainyu, at which point reality will undergo a cosmic renovation called Frashokereti[66] and limited time will end.According to tradition, the soul is judged by the Yazatas Mithra, Sraosha, and Rashnu, where depending on the verdict one is either greeted at the bridge by a beautiful, sweet-smelling maiden or by an ugly, foul-smelling old hag representing their Daena affected by their actions in life.[77] In the wake of Achaemenid expansion, shrines were constructed throughout the empire and particularly influenced the role of Mithra, Aredvi Sura Anahita, Verethragna and Tishtrya, alongside other traditional Yazata who all have hymns within the Avesta and also local deities and culture-heroes.Ritual exposure is currently mainly practiced by Zoroastrian communities of the Indian subcontinent, in locations where it is not illegal and diclofenac poisoning has not led to the virtual extinction of scavenger birds.[106] Zoroaster rejected many of the gods of the Bronze Age Iranians and their oppressive class structure, in which the Kavis and Karapans (princes and priests) controlled the ordinary people.He also opposed cruel animal sacrifices and the excessive use of the possibly hallucinogenic Haoma plant (conjectured to have been a species of ephedra or Peganum harmala), but did not condemn either practice outright, providing moderation was observed.[32] Some of the deities of the old religion, the Daevas (etymologically similar to the Sanskrit Devas), appeared to delight in war and strife and were condemned as evil workers of Angra Mainyu by Zoroaster.[123] Although no consensus exists on the chronology of the Avestan period, the lack of any discernable Persian and Median influence in the Avesta makes a time frame in the first half of the first millennium BCE likely.[128] Owing to the despotic rule of Cambyses and his long absence in Egypt, the whole people, Persians, Medes and all the other nations acknowledged the usurper, especially as he granted a remission of taxes for three years.[129] According to later Zoroastrian legend (Denkard and the Book of Arda Viraf), many sacred texts were lost when Alexander the Great's troops invaded Persepolis and subsequently destroyed the royal library there.For example, in the 9th century, a deeply venerated cypress tree in Khorasan (which Parthian-era legend supposed had been planted by Zoroaster himself) was felled for the construction of a palace in Baghdad, 2,000 miles (3,200 km) away.One example of this was a legend that Husayn, son of the fourth caliph Ali and grandson of Islam's prophet Muhammad, had married a captive Sassanid princess named Shahrbanu.This "wholly fictitious figure"[149] was said to have borne Husayn a son, the historical fourth Shi'a imam, who insisted that the caliphate rightly belonged to him and his descendants, and that the Umayyads had wrongfully wrested it from him.In the 16th century, in one of the early letters between Iranian Zoroastrians and their co-religionists in India, the priests of Yazd lamented that "no period [in human history], not even that of Alexander, had been more grievous or troublesome for the faithful than 'this millennium of the demon ofWrath'.They played an instrumental role in the economic development of the region over many decades; several of the best-known business conglomerates of India are run by Parsi-Zoroastrians, including the Tata,[158] Godrej, Wadia families, and others.[171] Some 10,000 adherents remain in the Central Asian regions that were once considered the traditional stronghold of Zoroastrianism, i.e., Bactria (see also Balkh), which is in Northern Afghanistan; Sogdiana; Margiana; and other areas close to Zoroaster's homeland.[204] Conversely, Zoroastrian influenced Hungarian, Slavic, Ossetian, Turkic and Mongol mythologies, all of which bear extensive light-dark dualisms and possible sun god theonyms related to Hvare-khshaeta.[citation needed] Gherardo Gnoli, in The Encyclopaedia of Religion,[225] says that we can assert that Manichaeism has its roots in the Iranian religious tradition and that its relationship to Mazdaism, or Zoroastrianism, is more or less like that of Christianity to Judaism.[228] It is noteworthy that Mani, who was brought up and spent most of his life in a province of the Persian empire, and whose mother belonged to a famous Parthian family, did not make any use of the Iranian mythological tradition.There can no longer be any doubt that the Iranian names of Sām, Narīmān, etc., that appear in the Persian and Sogdian versions of the Book of the Giants, did not figure in the original edition, written by Mani in the Syriac language
