Zoroastrianism

Overview: Zoroastrianism is a religious tradition of ancient Iranian origin, historically linked to the teachings attributed to Zarathustra and the worship of Ahura Mazda. Its theology, ethics, and cosmology deeply influenced the Iranian world and are the object of intense comparative study. The tradition preserves strong emphasis on truth, cosmic order, moral responsibility, ritual purity, and eschatological destiny.

Origin and development: The origins of Zoroastrianism are ancient and debated. Texts connected to the Gathas are often considered the closest to Zarathustra's initial preaching. Over the course of history, the religion developed liturgy, priesthood, a broader Avestan textual corpus, Pahlavi interpretations, and communal forms preserved especially in Iran and in Parsi India.

Beliefs and central themes: Recurrent themes include Ahura Mazda, asha, druj, moral choice, the Amesha Spentas, yazatas, ritual fire, purity, judgment of the soul, the Chinvat Bridge, final renewal, and the victory of good. Not all of these elements are formulated with the same weight in every phase of the tradition.

Texts and authority: The Avesta, especially the Gathas, occupies a central place, together with commentaries and later literature in Pahlavi. The tradition also depends on ritual practice, recitation, and priestly transmission.

Practices: These include daily prayers, use of Avestan formulas, reverence for ritual fire, observance of purity, communal ceremonies, rites of passage, and memory of the dead. In modern communities, some ancient practices are reinterpreted in light of different social and legal contexts.

Debates and internal diversity: There is academic debate about Zarathustra's chronology, the degree of original dualism, the relationship between the Gathas and later developments, the role of spiritual beings, and changes in funerary practices. There are also differences between Parsi and Iranian communal preservation and modern reformist readings.
