Zoroastrianism is an Iranian religion and one of the world's oldest organized faiths, based on the teachings of the Iranian-speaking prophet Zoroaster. It has a dualistic cosmology of good and evil within the framework of a monotheistic ontology and an eschatology which predicts the ultimate conquest of evil by good. Zoroastrianism exalts an uncreated and benevolent deity of wisdom known as Ahura Mazda as its supreme being. Historically, the unique features of Zoroastrianism, such as its monotheism, messianism, belief in free will and judgement after death, conception of heaven, hell, angels, and demons, among other concepts, may have influenced other religious and philosophical systems, including the Abrahamic religions and Gnosticism, Northern Buddhism, and Greek philosophy.
Ahura Mazda, also known as Asura Mazda, Oromasdes, Ohrmazd, Ormusd, Hoormazd, Harzoo, Hormazd, Hormaz and Hurmuz, is the creator deity and god of the sky in 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".
Angra Mainyu or Ahreman is the Avestan name of Zoroastrianism's hypostasis of the "destructive/evil spirit" and the main adversary in Zoroastrianism either of the Spenta Mainyu, the "holy/creative spirits/mentality", or directly of Ahura Mazda, the highest deity of Zoroastrianism. The Middle Persian equivalent is Ahriman 𐭠𐭧𐭫𐭬𐭭𐭩. The name can appear in English-language works as Ahrimanes.
Atar, Atash, Azar or Dāštāɣni, is the Zoroastrian concept of holy fire, sometimes described in abstract terms as "burning and unburning fire" or "visible and invisible fire". It is considered to be the visible presence of Ahura Mazda and his Asha through the eponymous Yazata. The rituals for purifying a fire are performed 1,128 times a year.
Saoshyant is the Avestan language expression that literally means "one who brings benefit", and which is used in several different ways in Zoroastrian scripture and tradition. In particular, the expression is the proper name of the Saoshyant, an eschatological saviour figure who brings about Frashokereti, the final renovation of the world in which evil is finally destroyed. The term was contracted to "Soshans" in Zoroastrian tradition, and came to apply to three saviour figures that progressively bring about the final renovation.
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.
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'.
Zurvanism is a fatalistic religious movement of Zoroastrianism in which the divinity Zurvan is a first principle who engendered equal-but-opposite twins, Ahura Mazda and Angra Mainyu. Zurvanism is also known as "Zurvanite Zoroastrianism", and may be contrasted with Mazdaism.
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 daevas 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.
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".
Sraosha is the Avestan name of the Zoroastrian yazata of "Conscience" and "Observance", which is also the literal meaning of his name.
Bushyasta is the Zoroastrian demon (daeva) of sloth. Her stock epithet is "the long-handed".
Ahuna Vairya is the first of Zoroastrianism's four Gathic Avestan formulas. The text, which appears in Yasna 27.13, is also known after its opening words yatha ahu vairyo. In Zoroastrian tradition, the formula is also known as the ahun(a)war.
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'. For other connotations, see Meaning below. 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".
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."
Aka Manah is the Avestan language name for the Zoroastrian daeva "Evil Mind", "Evil Purpose", "Evil Thinking", or "Evil Intention". Aka Manah is the demon of sensual desire that was sent by Ahriman to seduce the prophet Zoroaster. His eternal opponent is Vohu Manah. Aka Manah is the hypostatic abstraction of accusative akem manah, "manah made evil". The objectification of this malign influence is the demon Aka/Akem Manah, who appears in later texts as Middle Persian Akoman and New Persian Akvan.
Amerdad 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 /ˈhəʊrvətət/ 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.
Frashokereti is the Avestan language term for the Zoroastrian doctrine of a final renovation of the universe, when evil will be destroyed, and everything else will be then in perfect unity with God.
