Zoroastrianism is one of the world’s oldest monotheistic religions, originating in ancient Persia (modern-day Iran) roughly between 1500–1000 BCE.
Founder
It was founded by the prophet Zoroaster (also known as Zarathustra or Zartosht), a priest who received divine visions from Ahura Mazda (the “Wise Lord”), the supreme, all-good creator god. According to tradition, at around age 30, Zoroaster had a revelation emphasizing the worship of one true god and ethical living.
Core Beliefs
Zoroastrianism features both monotheistic and dualistic elements:
- Ahura Mazda is the one uncreated, benevolent God who created the universe and upholds cosmic order (asha — truth, righteousness, and order).
- Opposed to him is Angra Mainyu (or Ahriman), the destructive, all-evil spirit representing chaos and falsehood (druj).
- Humanity plays a central role through free will: people must actively choose good over evil in the cosmic struggle between light and darkness.
The religion’s foundational ethical principle is the Threefold Path:
- Good Thoughts (Humata)
- Good Words (Hukhta)
- Good Deeds (Hvarshta)
This promotes truth-telling, charity, moderation, love for others, and environmental stewardship (e.g., respect for the elements, especially fire as a symbol of purity).
Scriptures
The holy text is the Avesta, an ancient collection of hymns, prayers, and laws. The oldest and most sacred part is the Gathas, 17 hymns attributed directly to Zoroaster.
Afterlife and Eschatology
- Souls are judged after death at the Chinvat Bridge. The righteous cross into paradise; the wicked fall into a realm of torment.
- There is a belief in a final resurrection, a last judgment, and the ultimate triumph of good, where evil is defeated and the world is renewed (influencing later concepts in Judaism, Christianity, and Islam, such as angels, demons, heaven, hell, and apocalypse).
Practices
- Worship often occurs in fire temples, where a sacred fire (symbolizing Ahura Mazda’s light and purity) is kept burning. Fire is venerated but not worshiped.
- Key rituals include the yasna (a ceremonial offering and prayer service).
- Traditional funerary practices historically involved exposure of the dead to vultures on Towers of Silence to avoid polluting the earth, though this has evolved in modern communities.
History and Today
Zoroastrianism was the state religion of the Achaemenid, Parthian, and especially Sassanian Persian Empires. It declined sharply after the 7th-century Muslim conquest of Persia. Many followers fled to India, becoming the Parsis (a major community today).
There are an estimated 100,000–200,000 Zoroastrians worldwide, primarily in India (largest community), Iran, and diaspora populations in North America, the UK, and elsewhere. It remains a living faith emphasizing ethical monotheism and personal responsibility.
Zoroastrian ideas have had a profound, though often indirect, influence on Western religious thought through its impact on the Abrahamic faiths.
