Zoroastrianism

Zoroastrianism, also called Mazdayasna or Behdin, is an Iranian religion centred on the Avesta and the teachings of Zarathushtra Spitama, who is more commonly referred to by the Greek translation, 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 (𐬀𐬵𐬎𐬭𐬀⸱𐬨𐬀𐬰𐬛𐬁), who is hailed as the supreme being of the universe. Opposed to Ahura Mazda is Angra Mainyu (𐬀𐬢𐬭𐬀⸱𐬨𐬀𐬌𐬥𐬌𐬌𐬎), who is personified as a destructive spirit and the adversary of all things that are good. As such, the Zoroastrian religion combines a dualistic cosmology of good and evil with an eschatological outlook predicting the ultimate triumph of Ahura Mazda over evil. Opinions vary among scholars as to whether Zoroastrianism is monotheistic, polytheistic, henotheistic, or a combination of all three. Zoroastrianism shaped Iranian culture and history, while scholars differ on whether it significantly influenced ancient Western philosophy and the Abrahamic religions, or gradually reconciled with other religions and traditions, such as Christianity and Islam.

Originating from Zoroaster's reforms of the ancient Iranian religion, Zoroastrianism began during the Avestan period (possibly as early as the 2nd millennium BCE), but was first recorded in the mid-6th century BCE. For the following millennium, it was the official religion of successive Iranian polities, beginning with the Achaemenid Empire, which formalized and institutionalized many of its tenets and rituals, and ending with the Sasanian Empire, which revitalized the faith and standardized its teachings. In the 7th century CE, the rise of Islam and the ensuing Muslim conquest of Iran marked the beginning of the decline of Zoroastrianism. The persecution of Zoroastrians by the early Muslims in the nascent Rashidun Caliphate prompted much of the community to migrate to the Indian subcontinent, where they were granted asylum and became the progenitors of today's Parsis. Once numbering in the millions, the world's total Zoroastrian population is estimated to comprise between 110,000 and 120,000 people, with most of them residing either in India (50,000–60,000), in Iran (15,000–25,000), or in North America (22,000). Though the religion is currently sparse due to restrictions on conversion, strict endogamy, and low birth rates, there are reports of conversions and cultural embraces of Zoroastrianism among the Iranian peoples (particularly Persians), most notably among the diaspora.

The central beliefs and practices of Zoroastrianism are contained in the Avesta, a compendium of sacred texts assembled over several centuries. Its oldest and most central component are the Gathas, purported to be the direct teachings of Zoroaster and his account of conversations with Ahura Mazda. These writings are part of a major section of the Avesta called the Yasna, which forms the core of Zoroastrian liturgy. Zoroaster's religious philosophy divided the early Iranian gods of Proto-Indo-Iranian paganism into emanations of the natural world—the ahura and the daeva; the former class consisting of divinities to be revered and the latter class consisting of divinities to be rejected and condemned. Zoroaster proclaimed that Ahura Mazda was the supreme creator and sustaining force of the universe, working in gētīg (the visible material realm) and mēnōg (the invisible spiritual and mental realm) through the Amesha Spenta, a class of seven divine entities that represent various aspects of the universe and the highest moral good. Emanating from Ahura Mazda is Spenta Mainyu (the Holy or Bountiful Spirit), the source of life and goodness, which is opposed by Angra Mainyu (the Destructive or Opposing Spirit), who is born from Aka Manah (evil thought). Angra Mainyu was further developed by Middle Persian literature into Ahriman (𐭠𐭧𐭫𐭬𐭭𐭩), Ahura Mazda's direct adversary.

Zoroastrian doctrine holds that, within this cosmic dichotomy, human beings have the choice between Asha (truth, cosmic order), the principle of righteousness or "rightness" that is promoted and embodied by Ahura Mazda, and Druj (falsehood, deceit), the essential nature of Angra Mainyu that expresses itself as greed, wrath, and envy. Thus, the central moral precepts of the religion are good thoughts (hwnata), good words (hakhta), and good deeds (hvarshta), which are recited in many prayers and ceremonies. Many of the practices and beliefs of ancient Iranian religion can still be seen in Zoroastrianism, such as reverence for nature and its elements, such as water (aban). Fire (atar) is held by Zoroastrians to be particularly sacred as a symbol of Ahura Mazda himself, serving as a focal point of many ceremonies and rituals, and serving as the basis for Zoroastrian places of worship, which are known as fire temples.

The name Zoroaster (Ζωροάστηρ) is a Greek rendering of the Avestan name Zarathustra. He is known as Zartosht and Zardosht in Persian and Zaratosht in Gujarati. The Zoroastrian name of the religion is Mazdayasna, which combines Mazda- with the Avestan word yasna, meaning "worship, devotion". In English, an adherent of the faith is commonly called a Zoroastrian or a Zarathustrian. An older expression still used today is Behdin, meaning "of the good religion", deriving from beh < Middle Persian weh 'good' + din < Middle Persian dēn < Avestan daēnā". In the Zoroastrian liturgy, this term is used as a title for a lay individual who has been formally inducted into the religion in a Navjote ceremony, in contrast to the priestly titles of osta, osti, ervad (hirbod), mobed and dastur.

The first surviving reference to Zoroaster in English scholarship is attributed to Thomas Browne (1605–1682), who briefly refers to Zoroaster in his 1643 Religio Medici. The term Mazdaism (/ˈmæzdə.ɪzəm/) is an alternative form in English used as well for the faith, taking Mazda- from the name Ahura Mazda and adding the suffix -ism to suggest a belief system.

The theological category of Zoroastrianism is hard to define. The reasons are the difficulties in assigning precise dates to the principal texts and the fact that many contain much older material. Furthermore, Zoroastrianism shaped only slowly over time and was not complete even by the time of the Muslim conquest of Persia. Polytheistic, monotheistic, and dualistic strands can be identified in the wider Zoroastrian tradition, with dualism being the dominant tendency. The major difference to Manichaeism lies in the insistence of good in the creation account.

Some scholars believe Zoroastrianism started as an Indo-Iranian polytheistic religion: according to Yujin Nagasawa, "like the rest of the Zoroastrian texts, the Old Avesta does not teach monotheism". By contrast, Md. Sayem characterizes Zoroastrianism as being one of the oldest monotheistic religions in the world.
