Zoroastrianism, also known as Mazdayasna and Behdin, is an Iranian religion. Among the world's oldest organized faiths, it is based on the teachings of Iranian prophet Zarathustra — commonly known by his Greek name Zoroaster — as set forth in the primary religious text called the Avesta. Zoroastrians exalt an uncreated and benevolent deity of wisdom as the universe's supreme being, commonly referred to as Ahura Mazda. Opposed to Ahura Mazda is Angra Mainyu, who is personified as a destructive spirit and the adversary of all things good. Zoroastrianism combines a dualistic cosmology of good and evil with an eschatology that predicts the ultimate triumph of Ahura Mazda over evil. Opinions vary among scholars as to whether the religion 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.
The Avesta is the primary collection of religious literature of Zoroastrianism from at least the late Sassanid period. It is composed in the Avestan language, with the oldest surviving fragment of a text in the Avestan language dating to 1323 CE.
Yasna is the Avestan name of Zoroastrianism's principal act of worship. It is also the name of the primary liturgical collection of Avesta texts, recited during that yasna ceremony.
Vishtaspa is the Avestan-language name of a figure appearing in Zoroastrian scripture and tradition, portrayed as an early follower of Zoroaster, and his patron, and instrumental in the diffusion of the prophet's message. Although Vishtaspa is not epigraphically attested, he is – like Zoroaster – traditionally assumed to have been a historical figure, although obscured by accretions from legend and myth.
In Zoroastrianism, the Amesha Spenta are a class of seven divine entities emanating from Ahura Mazda, the highest divinity of the religion. Later Middle Persian variations of the term include the contraction 'Ameshaspand' as well as the specifically Zoroastrian 'Mahraspand' and 'Amahraspand'.
Middle Persian literature is the corpus of written works composed in Middle Persian, that is, the Middle Iranian dialect of Persia proper, the region in the south-western corner of the Iranian plateau. Middle Persian was the prestige dialect during the era of Sasanian dynasty. It is the largest source of Zoroastrian literature.
Vohu Manah is the Avestan language term for a Zoroastrian concept, generally translated as "Good Purpose", "Good Mind", or "Good Thought", referring to the good state of mind that enables an individual to accomplish their duties. Its Middle Persian equivalent, as attested in the Pahlavi script texts of Zoroastrian tradition, is 𐭥𐭤𐭥𐭬𐭭 Wahman, which is a borrowing of the Avestan language expression and has the same meaning, and which continues in New Persian as بهمن Bahman and variants. Manah is cognate with the Sanskrit word Manas suggesting some commonality between the ideas of the Gathas and those of the Rigveda. The opposite of Vohu Manah is akem manah or Aka Manah, "evil purpose" or "evil mind".
A daeva is a Zoroastrian supernatural entity with disagreeable characteristics. In the Gathas, the oldest texts of the Zoroastrian canon, the daevas are "gods that are rejected". This meaning is – subject to interpretation – perhaps also evident in the Old Persian "daiva inscription" of the 5th century BCE. In the Younger Avesta, the daeva's are divinities that promote chaos and disorder. In later tradition and folklore, the dēws are personifications of every imaginable evil. Over time, the Daeva myth as Div became integrated to islam.
Anērān or Anīrân is an ethno-linguistic term that signifies "non-Iranian" or "non-Iran" (non-Aryan). Thus, in a general sense, 'Aniran' signifies lands where Iranian languages are not spoken. In a pejorative sense, it denotes "a political and religious enemy of Iran and Zoroastrianism."
Peshotanu is an eschatological figure of the medieval texts of Zoroastrian tradition, in particular in the apocalyptic Zand-i Wahman yasn.
The Bundahishn is an encyclopedic collection of beliefs about Zoroastrian cosmology written in the Book Pahlavi script. The original name of the work is not known. It is one of the most important extant witnesses to Zoroastrian literature in the Middle Persian language.
Asha or arta is a Zoroastrian concept with a complex and highly nuanced range of meaning. It is commonly summarized in accord with its contextual implications of 'truth' and 'right', 'order' and 'right working'. It is of cardinal importance to Zoroastrian theology and doctrine. In the moral sphere, aṣ̌a/arta represents what has been called "the decisive confessional concept of Zoroastrianism". The opposite of Avestan aṣ̌a is 𐬛𐬭𐬎𐬘 druj, "deceit, falsehood".
Ashi is the Avestan language word for the Zoroastrian concept of "that which is attained." As the hypostasis of "reward," "recompense," or "capricious luck," Ashi is also a divinity in the Zoroastrian hierarchy of yazatas.
Aeshma is the Younger Avestan name of Zoroastrianism's demon of "wrath". As a hypostatic entity, Aeshma is variously interpreted as "wrath", "rage", and "fury". His standard epithet is "of the bloody mace".
Ameretat is the Avestan language name of the Zoroastrian divinity/divine concept of immortality. Amerdad is the Amesha Spenta of long life on earth and perpetuality in the hereafter.
Haurvatat is the Avestan language word for the Zoroastrian concept of "wholeness" or "perfection." In post-Gathic Zoroastrianism, Haurvatat was the Amesha Spenta associated with water, prosperity, and health.
Gavaevodata is the Avestan language name of the primordial bovine of Zoroastrian cosmogony and cosmology, one of Ahura Mazda's six primordial material creations and the mythological progenitor of all beneficent animal life.
Ancient Iranian religion or Iranian paganism was a set of ancient beliefs and practices of the Iranian peoples before the rise of Zoroastrianism. The religion closest to it was the historical Vedic religion that was practiced in India. The major deities worshipped were Ahura Mazda and Mithra from Iran to Rome, but Atar was also worshipped, as names of kings and common public showing devotion to these three exist in most cases. But some sects, the precursors of the Magi, also worshipped Ahura Mazda, the chief of the Ahuras. With the rise of Zoroaster and his new, reformatory religion, Ahura Mazda became the principle deity while the Daevas were relegated to the background. Many of the attributes and commandments of Varuna, called Fahrana in Median times, were later attributed to Ahura Mazda by Zoroaster.
Xwedodah is a type of consanguine marriage to have been historically practiced in Zoroastrianism before the Muslim conquest of Persia. Such marriages are recorded as having been inspired by Zoroastrian cosmogony and considered pious. It was a high act of worship in Zoroastrianism, and there were punishments for not performing it.
The Avestan period is the period in the history of the Iranians when the Avesta was produced. It saw important contributions to both the religious sphere, as well as to Iranian mythology and its epic tradition.
