Khordeh AvestaThe oldest Zoroastrian religious scripture, handed down from ancient times, is the Avesta. One section of the holy book is known as the Khordeh Avesta or Smaller (i. e. Selected) Avesta. This is the book of daily prayers of the Zoroastrians, including the most sacred prayers or manthras, as well as graces said over meals and other occasions, blessings, and hymns to spiritual beings. It is a cherished possession of every devout Zoroastrian household.
