Yasna

Yasna is the primary liturgical collection of Zoroastrianism, consisting of sacred hymns, prayers, and rituals used in worship. Composed in the ancient Avestan language, it serves as a guide for Zoroastrian ceremonies, expressing devotion to Ahura Mazda, the supreme god, and emphasizing themes like truth, righteousness, and order. Yasna is recited by priests during religious rituals and plays a central role in maintaining spiritual traditions, linking practitioners to their faith's historical roots and guiding moral conduct.
