Zoroastrian compendium of sacred literature

Avesta is the holy book of Zoroastrianism. It is written in the Avestan language, an Iranian language. The Avesta has also been translated into other languages including Farsi and English. The oldest portion, the Ghathas, are the religious songs composed by Zoroaster himself. Other parts of Avesta are named Yasna, Yashts, Visperad, Vendidad and Khordeh Avesta. There are two other religious texts in Zoroastrianism which are named Denkard and Ardaviraf Namak.
