Zoroastrianism, also called Mazdayasnā 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. Among the world's oldest organized faiths, its adherents exalt an uncreated, benevolent, and all-wise deity known as Ahura Mazda, 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.
Zarathushtra Spitama, more commonly known as Zoroaster or Zarathustra, was an Iranian religious reformer who challenged the tenets of the contemporary Ancient Iranian religion, becoming the spiritual founder of Zoroastrianism. Variously described as a sage or a wonderworker; in the oldest Zoroastrian scriptures, the Gathas, which he is believed to have authored, he is described as a preacher and a poet-prophet. He also had an impact on Heraclitus, Plato, Pythagoras, and the Abrahamic religions, including Judaism, Christianity, and Islam.
Ahura Mazda, also known as Horomazes, is the creator deity and god of the sky in the ancient Iranian religion Zoroastrianism. He is the first and most frequently invoked spirit in the Yasna. The literal meaning of the word Ahura is "lord", and that of Mazda is "wisdom".
Avestan is an umbrella term for two Old Iranian languages, Old Avestan and Younger Avestan. They are known only from their conjoined use as the scriptural language of Zoroastrianism. Both are early Eastern Iranian languages within the Indo-Iranian language branch of the Indo-European language family. Its immediate ancestor was the Proto-Iranian language, a sister language to the Proto-Indo-Aryan language, with both having developed from the earlier Proto-Indo-Iranian language; as such, Old Avestan is quite close in both grammar and lexicon to Vedic Sanskrit, the oldest preserved Indo-Aryan language.
Airyanem Vaejah is considered in Zoroastrianism to be the homeland of the early Iranians and the place where Zarathustra received the religion from Ahura Mazda. The Avesta also names it as the first of the "sixteen perfect lands" that Ahura Mazda created for the Iranians.
Magi, or magus, is the term for priests in Zoroastrianism and earlier Iranian religions. The earliest known use of the word magi is in the trilingual inscription written by Darius the Great, known as the Behistun Inscription. Old Persian texts, predating the Hellenistic period, refer to a magus as a Zurvanic, and presumably Zoroastrian, priest.
Mithra is an ancient Iranian deity (yazata) of covenants, light, oaths, justice, the Sun, contracts, and friendship. In addition to being the divinity of contracts, Mithra is also a judicial figure, an all-seeing protector of Truth (Asha), and the guardian of cattle, the harvest, and the Waters.
The Kambojas were a southeastern Iranian people who inhabited the northeastern most part of the territory populated by Iranian tribes, which bordered the Indian lands. They only appear in Indo-Aryan inscriptions and literature, being first attested during the later part of the Vedic period.
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".
Yazata is the Avestan word for a Zoroastrian concept with a wide range of meanings but generally signifying a divinity. The term literally means "worthy of worship or veneration", and is thus, in this more general sense, also applied to certain healing plants, primordial creatures, the fravashis of the dead, and to certain prayers that are themselves considered holy. The yazatas collectively are "the good powers under Ahura Mazda", who is "the greatest of the yazatas".
The Iranian languages, also called the Iranic languages, are a branch of the Indo-Iranian languages in the Indo-European language family that are spoken natively by the Iranian peoples, predominantly in the Iranian Plateau.
Apas is the Avestan language term for "the waters", which, in its innumerable aggregate states, is represented by the Apas, the hypostases of the waters.
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.
Khvarenah (also spelled khwarenah or xwarra(h): Avestan: 𐬓𐬀𐬭𐬆𐬥𐬀𐬵xᵛarənah) is an Avestan word for a Zoroastrian concept literally denoting "glory" or "splendour" but understood as a divine mystical force or power projected upon and aiding the appointed. The neuter noun thus also connotes "(divine) royal glory", reflecting the perceived divine empowerment of kings. The term also carries a secondary meaning of "(good) fortune"; those who possess it are able to complete their mission or function.
Avestan geography refers to the investigation of place names in the Avesta and the attempt to connect them to real-world geographical sites. It is connected to but different from the cosmogony expressed in the Avesta, where place names primarily refer to mythical events or a cosmological order.
The Cappadocian calendar was a solar calendar that was derived from the Persian Zoroastrian calendar. It is named after the historic region Cappadocia in present-day Turkey, where it was used. The calendar, which had 12 months of 30 days each and five epagomenal days, originated between 550 and 330 BC, when Cappadocia was part of the Persian Achaemenid Empire. The Cappadocian calendar was identical to the Zoroastrian calendar; this can be seen in its structure, in the Avestan names and in the order of the months. The Cappadocian calendar reflects the Iranian cultural influence in the region. Extant evidence of the calendar dates back to Late Antiquity through the accounts of Greek astronomers, by which time it had already been adapted to the Julian calendar.
A mantra or manthra is a prayer, sacred formula or inspired utterance considered in Zoroastrianism to have spiritual power. Their use already goes back to Zarathustra who described himself in his Gathas as a knower of mantras.
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.
Arya was the ethnonym used by Iranians during the early History of Iran. In contrast to cognates of Arya used by the Vedic people and Iranic steppe nomads, the term is commonly translated using the modern ethnonym Iranian.
