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.
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".
SraoshaSraosha (𐬯𐬭𐬀𐬊𐬴𐬀 or 𐬯𐬆𐬭𐬀𐬊𐬴𐬀 'sroː.ʃa) is the Avestan name of the Zoroastrian yazata of "Conscience" and "Observance", which is also the literal meaning of his name. In the Middle Persian commentaries of the 9th-12th centuries, the divinity appears as 𐭮𐭫𐭥𐭱, S(a)rosh. This form appears in many variants in New Persian as well, for example سروش, Sorūsh.
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.
