Introduction to Zoroastrianism

In this episode, Gary Arndt delves into the ancient and enduring religion of Zoroastrianism, exploring its origins, historical evolution, core beliefs, and contemporary status. Zoroastrianism, founded by Zarathustra (also known as Zoroaster) in eastern Persia, is recognized as one of the world's oldest monotheistic religions. Despite its significant historical influence, today it remains a minority faith with a dedicated global following.

Origins and Early Development

Gary begins by addressing the enigmatic figure of Zarathustra, whose exact lifespan remains uncertain, with estimates ranging from the 7th to the 13th century BC. "Sometime between the 7th and 13th century BC, a man was born in eastern Persia who had a revolutionary idea" (00:00). Zarathustra challenged the prevailing polytheistic beliefs of his time by advocating for the worship of a single, supreme deity, Ahura Mazda.

Zoroastrianism's foundational texts, the Gathas, are hymns and poems attributed to Zarathustra, forming the core of the Avesta, the religion's sacred scriptures. His teachings emphasized ethical monotheism, moral choice, and individual responsibility, positioning Ahura Mazda as the embodiment of wisdom, truth, and goodness.

Influence During the Achaemenid Empire

The religion gained prominence under the Achaemenid Empire (550–330 BC), founded by Cyrus the Great. While it remains unclear if Cyrus was a devout Zoroastrian, his policies facilitated the spread of Zoroastrianism across a vast empire stretching from India to Greece. The "Cyrus Cylinder," often hailed as the first charter of human rights, reflects Zoroastrian values of justice and religious freedom, although it notably references the Babylonian god Marduk instead of Ahura Mazda.

Under Achaemenid rule, particularly during the reign of Darius I, Zoroastrianism flourished, promoting religious tolerance and influencing other major religions with concepts such as cosmic dualism, divine judgment, and messianic salvation.

Hellenistic and Parthian Periods

The conquest of Persia by Alexander the Great in 330 BC marked the beginning of Hellenistic influence on Zoroastrianism. The subsequent Greek dynasties introduced philosophical ideas that the religion had to absorb and adapt to maintain its identity. During the Parthian period (247 BC – 224 AD), Zoroastrianism developed a more structured priestly class and elaborate rituals, although its scriptures remained largely oral until later centuries.

Sassanid Revival and the Golden Age

The rise of the Sassanid dynasty in 224 AD heralded a significant revival of Zoroastrianism, establishing it as the state religion of Persia. This era, considered the religion's second golden age, saw the compilation and formalization of Zoroastrian scriptures. The Sassanid rulers fortified Zoroastrianism's theological framework, ritual practices, and priestly hierarchy, positioning it as a strong cultural and religious contender against the Byzantine Empire's Christian expansions.

Decline Following the Muslim Conquest

The Arab Muslim conquest of Persia in 651 AD drastically altered Zoroastrianism's landscape. Initially granted protected status as a People of the Book, Zoroastrians faced increasing social and economic pressures that encouraged conversions to Islam. Over centuries, the once-prominent religion dwindled to small, isolated communities, primarily in central Iran's Yazd and Kerman provinces.

The Parsi Migration and Modern Diaspora

A pivotal moment in Zoroastrian history was the migration of Parsis from Persia to western India around the 8th century AD. These refugees established thriving communities in Gujarat, successfully blending their Persian heritage with Indian cultural elements. The Parsis became influential in India's commerce, industry, philanthropy, and public service, particularly during British colonial rule. Figures like the renowned musician Freddie Mercury highlight the global dispersion of Zoroastrian communities, now numbering between 110,000 and 190,000 worldwide, with significant populations in India, Iran, the United States, Canada, and Australia.

Core Beliefs and Ethical Principles

At the heart of Zoroastrianism lies the worship of Ahura Mazda, the uncreated and supreme God who embodies pure wisdom and goodness. Gary explains, "Ahura Mazda represents pure wisdom, truth, and goodness" (Timestamp not available). The religion's ethical framework is encapsulated in the principle of Humata, Hukta, Varshta—good thoughts, good words, and good deeds. This triad underscores the importance of aligning human actions with divine will to aid in the cosmic struggle between good and evil.

Zoroastrianism presents a dualistic cosmology where Ahura Mazda's forces contend with Angra Mainu, the embodiment of evil. However, this dualism is not absolute; evil is ultimately fated to be defeated through the collective moral efforts of humanity. Free will is a cornerstone, as individuals must choose between truth and falsehood, light and darkness, thereby influencing both their personal salvation and the world's ultimate destiny.

Afterlife and Eschatology

Belief in the immortality of the soul and individual judgment after death are central tenets of Zoroastrianism. Upon death, souls traverse the Chinvat Bridge, where their deeds are weighed. "The righteous proceed to paradise, while the wicked fall into hell" (Timestamp not available). Unlike some other religions, Zoroastrianism teaches that punishment is not eternal; ultimately, all souls will be purified and reunited with Ahura Mazda. The religion envisions a final renovation of the world (frashokereti), where a savior figure, the Saoshyant, will resurrect the dead, judge humanity, and establish a perfected world free from evil.

Worship and Ritual Practices

Zoroastrianism venerates the natural elements—fire, water, earth, and air—as sacred creations of Ahura Mazda. Fire holds a special place as a symbol of divine light and purity, central to the religion's practices. Zoroastrian fire temples are sacred spaces where a perpetual flame burns, maintained by specially trained priests. These priests engage in ritual feedings of sandalwood and incense to keep the fire burning, symbolizing the continuous presence of divine truth.

One of the most distinctive practices is the traditional funeral rite involving the Tower of Silence. Due to the belief that a corpse contaminates the earth, fire, and water, Zoroastrians avoid burial and cremation. Instead, bodies are placed atop these stone towers and exposed to the elements and scavenging birds, typically vultures. "The corpse is laid on top of the tower in designated rings, men in the outermost, women in the middle, and children in the innermost circles" (Timestamp not available). This method ensures that the sacred elements remain unpolluted.

Preservation and Continuity

Despite facing centuries of decline and diaspora, Zoroastrian communities have remarkably preserved their religious heritage through meticulous transmission of texts, rituals, and traditions. The Parsi community, in particular, has thrived by adapting to new environments while maintaining core Zoroastrian practices. Modern Zoroastrians continue to uphold ancient rituals and contribute to cultural and societal advancements globally.

Conclusion

Zoroastrianism stands as a testament to the resilience of ancient religious traditions in the modern world. From its revolutionary monotheistic origins to its profound influence on other major religions, Zoroastrianism has played a pivotal role in shaping ethical and theological discourse. Today, a small yet vibrant global community continues to preserve and celebrate its rich heritage, ensuring that the teachings of Zarathustra endure for future generations.

Transcript

Gary Arndt (0:00)

Sometime between the 7th and 13th century BC, a man was born in eastern Persia who had a revolutionary idea. He claimed there weren't multiple gods, but rather just one God. He established a religion which at various times was one of the most followed in the world, and thousands of years later it still has adherents even though it's only a fraction of what it once was.

Zoroastrianism is one of the world's oldest religions, but today it's also one of the world's smallest. The origins of Zoroastrianism date back to its founder Zarathustra, also known as Zoroaster in the West. The details surrounding Zoroaster's life are murky and estimates vary widely. Some put him alive around the year 1500 B.C. and others closer to 600 B.C. and that's almost a 1000 year span, which is absolutely enormous. He had to have been born in a pastoral society in what is now northeastern Iran or southwestern Afghanistan. And beyond this we know next to nothing about him. What we do know, as is the case with many ancient religious figures, comes to us through his teachings. Zoroastrianism is centered on the teachings of Zoroaster, who is believed to have composed a series of hymns and poems known as known as the Gathas, which formed the core of the Avesta, the sacred scriptures of Zoroastrianism. Zoroaster preached a message of ethical monotheism declaring Ahura Mazda, or the Wide Lord as the supreme uncreated God and source of all that is good. He opposed the traditional polytheism of Indo Iranian religion and emphasized moral choice and individual responsibility. Zoroastrianism is one of three very early monotheistic religions that developed in the ancient world. One of the first was established by the Egyptian pharaoh Akhenaten, who established the cult of the Aten in Egypt in the 14th century BC. This didn't last very long and it was abolished soon after his death by his son Tutankhamun. Judaism is the other major ancient monotheistic religion which was probably established after or near the same time as Zoroastrianism. Although as I noted above, the dates are in serious question. While many aspects of Zoroaster's and Zoroastrianism's origins are shrouded in history, we do know that the religion gained popularity and reached its peak during the Achaemenid empire in the 6th century BC. As I covered in a previous episode, the Achaemenid Empire, also known as the First Persian Empire, was founded by Cyrus the Great in 550 BC. It isn't known if Cyrus himself was a Zoroastrian, but even if he wasn't he, he was indirectly responsible for the spread of Zoroastrianism. The famous Cyrus cylinder, a clay cylinder inscribed with cuneiform script, is often referred to as the first charter of human rights in the world, embodying Zoroastrian values of justice and religious freedom. However, it doesn't reference Ahura Mazda, but rather the Babylonian God Marduk. This empire, which stretched from India all the way to Greece, became the vehicle through which Zoroastrian ideas spread around the ancient world. The Achaemenid kings, particularly Darius I, did embrace Zoroastrian principles while maintaining religious tolerance throughout their vast domains. During this period, Zoroastrian concepts began influencing other religious traditions. The religion's emphasis on cosmic dualism, divine judgment, resurrection and messianic salvation would later appear as themes in both Judaism, Christianity and Islam. The conquest of Persia by Alexander the Great in 330 BC marked the beginning of centuries of foreign rule that changed the dominance of Zoroastrianism under the Greek dynasties that came after Alexander the Great. The religion was influenced by Greek philosophical ideas and competition from other belief systems. During the Parthian period In Persia, from 247 BC to the year 224, Zoroastrianism began to develop its distinctly priestly class structure and elaborate ritual practices. The oral traditions of Zoroaster's teachings were systematized, though they still wouldn't be written down until much later. This period saw the religion adapting to survive under non Zoroastrian rulers while still trying to maintain its core identity. The rise of the Sassanid dynasty in 224 brought about a remarkable revival of Zoroastrianism as the state religion of Persia, and this period represents the religion's second golden age. Under Sassanid rule, the Zoroastrian scriptures were finally compiled and written down. For the first time, the religion developed sophisticated theological concepts, elaborate fire temple rituals and a powerful priestly hierarchy. Sassanid Persia emerged as a significant rival to the Byzantine Empire, with Zoroastrianism serving as a unifying force against the expansion of Christianity. The Arab Muslim conquest of Persia in 651 fundamentally transformed Zoroastrianism's position in Persia. Initially, Muslims granted, Zoroastrians protected status as People of the Book, allowing them to practice their religion while paying special taxes. Zoroastrianism initially had the same status as other monotheistic religions, Judaism and Christianity. However, social and economic pressures gradually encouraged people to convert to Islam. Over the following centuries, Zoroastrian communities steadily diminished through conversion, intermarriage and emigration. The religion retreated to small, isolated communities, particularly in the Yazd and Kerman provinces of central Iran. Despite this decline, Zoroastrian communities maintained their religious practices and cultural identity with remarkable tenacity. One of the most significant developments in Zoroastrian history was the migration of Persian Zoroastrians to western India beginning around the 8th century. These refugees, who became known as Parsis, meaning from Persia, established thriving communities along India's western coast, particularly in Gujarat. The Parsis developed remarkably well to their new environment while preserving their religious traditions. They developed a unique blend of Persian Zoroastrian heritage with Indian cultural elements, creating a distinct community identity that, like the Zoroastrians in Iran, would prove remarkably resilient over the centuries. During the medieval period, both Iranian and Indian Zoroastrian communities focused on preserving their religious heritage through careful transmission of texts, rituals, and traditions. Parsis priests maintained correspondence with their Iranian counterparts, seeking guidance on religious matters and ensuring doctrinal consistency. This period witnessed the composition of important Zoroastrian texts in Middle Persian, followed by later versions in Persian and Gujarati. Religious scholars worked to interpret ancient texts for contemporary communities, developing commentaries and theological treaties that would guide the religion through centuries of minority status. The arrival of European colonial powers in India paradoxically benefited the Parsi community, whose education, business acumen, and cultural adaptability made them valuable intermediaries between Indian and European societies. During British rule, the Parsis became prominent in commerce, industry, philanthropy, and public service. The 19th and 20th centuries witnessed a remarkable Parsi renaissance, with community members playing leading roles in India's industrial development, independence movement, and cultural life. Simultaneously, Zoroastrian communities began emigrating globally, establishing diaspora communities in Europe, North America, and Australia. One of the most notable modern Zoroastrians, Freddie Mercury, came from a Parsi family that had migrated to Zanzibar. Today, There are approximately 110 to 190,000 Zoroastrians worldwide, primarily residing in India and Iran, with with other notable populations in the United States, Canada, and the Kurdish regions of Iraq. So far I've discussed the history of Zoroastrianism. But aside from being monotheistic, what exactly do Zoroastrians believe and how do they worship? As I stated near the beginning of this episode, at the heart of Zoroastrianism lies the worship of Ahura Mazda, who is the uncreated creator of all existence. Zoroastrians believe that Ahura Mazda represents pure wisdom, truth, and goodness. The deity is omniscient, omnipotent, and perfectly just, serving as the ultimate source of moral law and cosmic order. Zoroastrian ethics center on the fundamental principle of Humata hukta varshta, which means good thoughts, good words, and good deeds. This triad represents the three paths through which humans can align themselves with the divine will and contribute to the cosmic struggle between good and evil. Every human action, word, and even thought carries moral weight and consequences. In this system, Zoroastrian presents a dualistic cosmology where the universe is a battleground between the forces of good, led by Ahura Mazda, and evil, represented by Angra Mainu. However, this dualism is not absolute. Evil is ultimately destined for defeat, and humans play a crucial role in this cosmic drama through their exercise of free will. In Zoroastrianism, every person must choose between truth and falsehood, light and darkness, order and chaos. This choice carries profound consequences, not only for individual salvation, but for the ultimate fate of creation itself. Zoroastrians believe in the immortality of the soul and individual judgment after death. Upon death, each soul crosses the Chinvat bridge, where their deeds are weighed. The righteous proceed to paradise, while the wicked fall into hell. However, unlike other religions, this punishment is not eternal. Ultimately, they believe all souls will be purified and reunited with Ahura Mazda. The religion teaches that history will culminate in the frascio credi, or renovation of the world, which is their version of the Apocalypse. A savior figure known as the Seochant will emerge to resurrect the dead, judge all humanity, and establish a perfected world where evil is finally vanquished. Zoroastrianism reveres the elements of fire, water, earth and air as sacred creations of Ahura Mazda. Fire holds particular significance as a symbol of divine light and purity, leading to the religion's association with fire worship. Although Zoroastrians worship through fire, not the fire itself, contemporary Zoroastrian practices center on fire temples. Zoroastrian fire temples are sacred places where the element of fire is enshrined and venerated as a symbol of divine truth, purity, and the presence of Ahura Mazda. Unlike places of congregational worship and other religions, Zoroastrian fire temples are not designed to be gathering halls for sermons. They are sanctuaries designed around the continuous tending and ritual maintenance of a sacred flame. At the heart of every fire temple is the sanctum, a secluded inner chamber where the sacred fire is housed. Only specially trained priests may enter this chamber. The fire itself is kept burning perpetually and is treated as a living symbol of divine order. To maintain the fire, priests perform ritual feedings of sandalwood and incense multiple times a day, always with prayers and under strict purity conditions. Before entering the sacred area, the priest undergoes ritual cleansing and wears white garments, including a mouth covering, to prevent contamination of the flame by breath or saliva. Perhaps the most unusual practice of Zoroastrianism, however, is its traditional funeral rites. Zoroastrians believe that a dead body is immediately contaminated by nasu, a corpse demon that causes spiritual pollution. Contact with a corpse endangers ritual purity and thus extreme care is taken to prevent the sacred elements from being tainted by decomposition. And for this reason you cannot bury a body as it would contaminate the earth. The body also cannot be burned as it would desecrate fire and air. And likewise, you can't perform a burial at sea as it would pollute the water. So if all those options are off the table, what else can you do? The traditional Zorian Astrin practice of disposing of corpses involves what's known as a Tower of Silence. A tower of Silence is a circular, roofless stone structure, typically raised and located on a hill, where dead bodies are laid out and exposed to the elements, as well as scavenging birds, primarily vultures. The corpse is laid on top of the tower in designated rings, men in the outermost, women in the middle, and children in the innermost circles. Birds consume the soft tissues and the sun sanitizes what remains. Bones are later collected into an ossuary where they disintegrate over time. Zoroastrianism is one of the few religions that has existed for over 2000 years and continues to exist today. Despite its brief golden ages. Over a thousand years ago, the religion never really spread far beyond Persia and other parts of western India. But thousands of years later, they still remain a small community who managed to keep their ancient traditions alive. The Executive producer of Everything Everywhere Daily is Charles Daniel.
