Yasna

Yasna refers both to a principal Zoroastrian liturgical ceremony and to the collection of texts recited during that ritual. The Yasna includes prayers, invocations, and hymns arranged for ceremonial performance, among them the Gathas, which are traditionally linked to Zoroaster. Its content centers on praise of Ahura Mazda, affirmation of cosmic order, ethical responsibility, and correct ritual action. The Yasna functions as the backbone of communal worship, preserving theology, ritual structure, and religious language through repeated public recitation.
