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.
GavaevodataGavaevodata () 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. The primordial beast is killed in the creation myth, but from its marrow, organs and the world is repopulated with animal life. The soul of the primordial bovine – geush urvan – returned to the world as the soul of livestock.
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".
FravashiFravashi (𐬟𐬭𐬀𐬎𐬎𐬀𐬴𐬌, frəˈvɑ:ʃi) is the Avestan term for the Zoroastrian concept of a personal spirit of an individual, whether dead, living, or yet-unborn. The fravashi of an individual sends out the urvan (often translated as 'soul') into the material world to fight the battle of good versus evil. On the morning of the fourth day after death, the urvan returns to its fravashi, where its experiences in the material world are collected to assist the next generation in their fight between good and evil.
Parthian EmpireThe Parthian Empire (ˈpɑrθiən), also known as the Arsacid Empire (ˈɑrsəsɪd), was a major Iranian political and cultural power in ancient Iran from 247 BC to 224 AD. Its latter name comes from its founder, Arsaces I, who led the Parni tribe in conquering the region of Parthia in Iran's northeast, then a satrapy (province) under Andragoras, who was rebelling against the Seleucid Empire. Mithridates I (171-132 BC) greatly expanded the empire by seizing Media and Mesopotamia from the Seleucids.
Sasanian EmpireThe Sasanian Empire (səˈsɑːniən,_səˈseɪniən), officially known as Eranshahr ("Land/Empire of the Iranians"), was the last Iranian empire before the early Muslim conquests of the 7th–8th centuries AD. Named after the House of Sasan, it endured for over four centuries, from 224 to 651 AD, making it the longest-lived Persian imperial dynasty. The Sasanian Empire succeeded the Parthian Empire, and re-established the Persians as a major power in late antiquity alongside its neighbouring arch-rival, the Roman Empire (after 395 the Byzantine Empire).
Zoroastrian calendarAdherents of Zoroastrianism use three distinct versions of traditional calendars for liturgical purposes, all derived from medieval Iranian calendars and ultimately based on the Babylonian calendar as used in the Achaemenid empire. Qadimi ("ancient") is a traditional reckoning introduced in 1006. Shahanshahi ("imperial") is a calendar reconstructed from the 10th century text Denkard. Fasli is a term for a 1906 adaptation of the 11th century Jalali calendar following a proposal by Kharshedji Rustomji Cama made in the 1860s.
MithraMithra ( Miθra, 𐎷𐎰𐎼 Miça), commonly known as Mehr or Mithras among Romans, is an ancient Iranian deity of covenants, light, oath, 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, and the guardian of cattle, the harvest, and the Waters. The Romans attributed their Mithraic mysteries to Zoroastrian Persian sources relating to Mithra.
AvestaThe Avesta (ə'vɛstə) is the primary collection of religious texts of Zoroastrianism, composed in the Avestan language. The Avesta texts fall into several different categories, arranged either by dialect, or by usage. The principal text in the liturgical group is the Yasna, which takes its name from the Yasna ceremony, Zoroastrianism's primary act of worship, and at which the Yasna text is recited. The most important portion of the Yasna texts are the five Gathas, consisting of seventeen hymns attributed to Zoroaster himself.
