Zoroastrianism is one of the world's oldest monotheistic religions, founded by the Prophet Zoroaster (or Zarathustra) in ancient Persia approximately in the 6th century BCE. It centers around the worship of Ahura Mazda, the Wise Lord, who represents all that is good, against his eternal opposite, Angra Mainyu, the spirit of evil.

Origins: Zoroastrianism emerged in the ancient Persian Empire and became the state religion under the Achaemenid dynasty from the 6th to the 4th century BCE.

Influence on Other Religions: The concepts of heaven and hell, judgment after death, and free will in Zoroastrianism have influenced other major world religions, including Judaism, Christianity, and Islam.

Decline and Revival: After the Muslim conquest of Persia, Zoroastrianism gradually declined due to conversions to Islam. However, significant communities persisted, especially in India, where they are known as Parsis.

Dualism: Zoroastrianism is based on the cosmic dualism between Ahura Mazda and Angra Mainyu, representing the ongoing battle between good and evil within the universe and within every individual.

Asho Zarathustra’s Teachings: The teachings of Zoroaster are collected in the Avesta, the holy book of Zoroastrianism, which includes the Gathas, hymns thought to be composed by Zoroaster himself.

Moral Choice: Central to Zoroastrianism is the emphasis on moral choice; individuals are responsible for their actions and are urged to choose the path of righteousness (Asha) over wrongdoing (Druj).

Fire Temples: Zoroastrians worship in fire temples, where a sacred fire is kept burning continuously, symbolizing the light of Ahura Mazda and the eternal fight against darkness.

Rituals and Ceremonies: Important rituals include the Navjote or initiation ceremony, marriage rites, and funerals, which involve specific prayers and practices to promote the soul's journey after death.

Community and Ethics: Community, charity, and righteous living are fundamental aspects of Zoroastrian life, emphasizing the importance of good thoughts, good words, and good deeds.

Cultural Contributions: Zoroastrianism has contributed significantly to the cultural and philosophical heritage of the Middle East and Central Asia, influencing art, music, and literature.

Social Structure and Modern Issues: Zoroastrians today continue to uphold a tight-knit community structure that places a strong emphasis on family values, education, and social responsibility.

Global Diaspora: While small in numbers, with estimates around 200,000 worldwide, the Zoroastrian diaspora is vibrant, particularly in India, Iran, and North America.

Challenges: Modern Zoroastrians face challenges such as declining numbers due to strict exogamous practices and the need for adaptation to contemporary societal norms while preserving religious identity.

Zoroastrianism's rich theological framework and historical legacy continue to influence its adherents and the broader world. Its emphasis on moral purity and the eternal struggle between good and evil offer profound insights into the human condition and the pursuit of spiritual enlightenment.
