Jul 17, 2025

Overview

This lecture covers Zoroastrianism, its founder, key beliefs, cosmic dualism, ethics, practices, and historical influence as a bridge between Eastern and Western religions.

Origins and Founder

  • Zoroastrianism was founded by Zarathustra (Persian name), also known as Zoroaster (Greek name).
  • Zarathustra likely lived around 1737-1660 BCE based on Zoroastrian calendars, but his exact dates are uncertain.
  • He originated from the Persian region, possibly near modern-day Iran or Iraq.
  • He promoted monotheism amid prevailing polytheism and claimed to receive a vision from the divine.

Core Beliefs and Theology

  • Zoroastrianism teaches "duotheism": two eternal gods—Ahura Mazda (good) and Angra Mainyu (evil).
  • Ahura Mazda ("the Wise Lord") is the creator god associated with truth, light, and wisdom.
  • Angra Mainyu ("the Liar") embodies evil, deceit, and chaos.
  • Both gods are uncreated, eternal, and locked in cosmic conflict; neither can destroy the other.
  • Humans have free will and play a pivotal role in the battle by choosing good or evil.

Cosmology and Ethics

  • The universe is divided into two worlds: Menog (perfect spiritual realm) and Getig (imperfect material world).
  • Good and evil are absolute, with no gray area; actions align you with either side.
  • Salvation is achieved by building a metaphorical bridge to heaven through good deeds.
  • The core ethical mantra: good thoughts, good words, good deeds.
  • Anyone, regardless of religion, can reach heaven by doing good; hypocrisy is not tolerated.

Historical Timeline and Prophecies

  • Zoroastrianism outlines a 12,000-year cosmic timeline with four eras.
  • Zarathustra appears at the 9,000-year mark to restore order.
  • Successive saviors (Saoshyants) arise every 1,000 years.
  • At the end of time, good triumphs, all souls are judged, hell is emptied, and paradise is restored.

Practices and Rituals

  • Prayers are performed five times daily, often at fire altars (fire is a symbol of purity, not worship).
  • Dead are traditionally left in Towers of Silence for vultures, avoiding pollution of earth, water, or fire.
  • Strong environmental ethic: pollution of earth, water, or fire is strictly forbidden.
  • Priests are called Magi, serving as both religious leaders and astrologers.

Influence and Legacy

  • Zoroastrian beliefs influenced later Western religions (Judaism, Christianity, Islam) in concepts of angels, judgment, and dualism.
  • Emphasized equality and the first known declaration of human rights in the Persian Empire.
  • Modern Zoroastrian communities are mostly in India (Parsis) and face contemporary challenges with burial practices.
