Ritials have always played an important role in the practical area of religion, which also applies to the Zoroastrian religion. The Avestan texts can be divided into two categories based on their ritual use: the texts recited in the rituals by the priests in the Fireplace, such as Yasna, Visperad and Vendidad and the second category of Avestan texts, such as the Yasts and Avesta fragments, can be read outside of the fireplace by other People in the community.
