Khordeh Avesta (Khordeh Avesta Bā-Māyeni). The oldest Zoroastrian religious scripture, as preserved at present, is known as the Avesta. A section of this Avesta is known as the “Khordeh-Avesta’ which means the “Smaller or Selected Avesta”. This is the book of daily prayers of the Zoroastrians. It is a cherished possession of every devoted Zoroastrian household. The Khordeh Avesta is a collection of prayers selected from other major works of extant Avesta literature such as Yasna, Vispered, Vendidad, and the Yasht Literature
