YazataYazata (𐬫𐬀𐬰𐬀𐬙𐬀) is the Avestan word for a Zoroastrian concept with a wide range of meanings but generally signifying (or used as an epithet of) 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".
AshaAsha (ˈʌʃə) or arta (ˈɑrtə; 𐬀𐬴𐬀 Aṣ̌aArta) 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' (or 'righteousness'), '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".
YashtThe Yashts are a collection of twenty-one hymns in the Younger Avestan language. Each of these hymns invokes a specific Zoroastrian divinity or concept. Yasht chapter and verse pointers are traditionally abbreviated as Yt. The word yasht derives from Middle Persian 𐭩𐭱𐭲 yašt (“prayer, worship”) probably from Avestan 𐬫𐬀𐬱𐬙𐬀 (yašta, “honored”), from 𐬫𐬀𐬰 (yaz, “to worship, honor”), from Proto-Indo-European *yeh2ǵ- or *Hyaǵ-, and several hymns of the Yasna liturgy that "venerate by praise" are—in tradition—also nominally called yashts.
AhuraAhura (Avestan: 𐬀𐬵𐬎𐬭𐬀) is an Avestan language designation for a particular class of Zoroastrian divinities. The term is assumed to be linguistically related to the Asuras of Indian Vedic era. Avestan ahura "lord" derives from Proto-Indo-Iranian language *Hásuras, also attested in an Indian context as Rigvedic asura. As suggested by the similarity to the Old Norse æsir, Indo-Iranian *Hásuras may have an even earlier Proto-Indo-European language root.
AtarAtar, Atash, Azar (𐬁𐬙𐬀𐬭) or Dāštāɣni, is the Zoroastrian concept of holy fire, sometimes described in abstract terms as "burning and unburning fire" or "visible and invisible fire" (Mirza, 1987:389). 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. In the Avestan language, ātar is an attribute of sources of heat and light, of which the nominative singular form is ātarš, source of Persian ātaš (fire).
YasnaYasna (ˈjʌsnə; ,) 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. The function of the yasna ceremony is, very roughly described, to strengthen the orderly spiritual and material creations of Ahura Mazda against the assault of the destructive forces of Angra Mainyu. The yasna service, that is, the recitation of the Yasna texts, culminates in the apæ zaothra, the "offering to the waters.
DaevaA daeva (Avestan: 𐬛𐬀𐬉𐬎𐬎𐬀 daēuua) is a Zoroastrian supernatural entity with disagreeable characteristics. In the Gathas, the oldest texts of the Zoroastrian canon, the daevas are "gods that are (to be) 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 (Zoroastrian Middle Persian; New Persian divs) are personifications of every imaginable evil.
RashnuRashnu (𐬭𐬀𐬴𐬢𐬏) is the Avestan language name of the Zoroastrian yazata of justice. Together with Mithra and Sraosha, Rashnu is one of the three judges who pass judgment on the souls of people after death. Rashnu's standard appellation is "the very straight." In the Bundahishn, a Zoroastrian account of creation finished in the 11th or 12th century, Rashnu (Middle Persian: Rashn) is identified as an assistant of the Amesha Spenta Ameretat (Amurdad), "immortality". (GBd xxvi.115).
Chinvat BridgeThe Chinvat Bridge (Avestan: 𐬗𐬌𐬥𐬬𐬀𐬙𐬋 𐬞𐬈𐬭𐬈𐬙𐬏𐬨 Cinvatô Peretûm, "bridge of judgement" or "beam-shaped bridge") or the Bridge of the Requiter in Zoroastrianism is the sifting bridge, which separates the world of the living from the world of the dead. All souls must cross the bridge upon death. The bridge is guarded by two four-eyed dogs, described in the Videvdat (Vendidad) 13,9 as 'spâna pəšu.pâna' ("two bridge-guarding dogs"). The Bridge's appearance varies depending on the observer's asha, or righteousness.
AshiAshi (Avestan: 𐬀𐬴𐬌 aṣ̌i/arti) 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. Avestan 'ashi' is a feminine abstract noun, deriving from the root ar-, "to allot," with a substantivizing -ta suffix, hence aṣ̌i/arti "that which is granted." In the Avesta, the term implies both material and spiritual recompense.
