I. A Fundamental Human Question

Imagine living on the Iranian plateau over 3,000 years ago. At dawn, the sun rises to illuminate vast grasslands; at night, darkness descends, accompanied by howling winds. You witness crops flourishing in the rain, yet you also see droughts turn fields into barren wastelands. You have experienced the joy of peace and the terror of war.

A simple question takes root in the human heart: Why does this world contain both beauty and suffering?

Different civilizations have offered different answers. The ancient Egyptians placed their hope in the resurrected Osiris; the ancient Greeks appealed to the whims of the Fates; the ancient Indians used "Karma" to explain worldly injustices. Later, the monotheistic religions that came to dominate the Western world (Judaism, Christianity, and Islam) posited that all things originate from a single God, and that evil is either created or permitted by Him—a premise that leads to a thorny dilemma: "If God is all-good and all-powerful, why does evil exist?"

However, around 1200 BCE, a Persian prophet named Zoroaster provided a radically different answer. His insight was so profound that it influenced Judaism, Christianity, Islam, and even Greek philosophy for the next three millennia.

His core insight was this: the essence of the universe is not "monistic," but "dualistic." The world is a tapestry of good and evil because it is, in itself, a battlefield—an eternal war between good and evil, light and darkness, truth and falsehood.

The significance of this answer lies in the fact that it neither evades evil nor shifts the blame onto God. It acknowledges that evil is real, but declares that it is not final. The universe is a war—and war implies an undecided outcome, meaning every choice carries weight, and humans are not passive spectators, but active combatants.

Three thousand years ago, Zoroaster saw this light on the Iranian plateau. In his theological vision, this war was not fought by two opposing giants alone—there were seven rays of ancient light, seven archangels, who translated the attributes of God into tangible moral and natural orders.

But first, we must grasp the most fundamental question: What does dualism actually mean?

II. The "First Principle" of Zoroastrianism

To understand Zoroastrianism, one must begin with dualism. Dualism is not merely an "opinion" within this religion; it is its first principle—the foundation upon which all other doctrines are built.

2.1 What is Dualism?

Simply put, dualism posits that good and evil are two independent, eternal, and opposing principles.

This is not "two sides of the same coin" (like Shiva in Hinduism, who represents both creation and destruction), nor is it the idea that "evil is merely the absence of good" (as argued by the Christian theologian Augustine).

Zoroastrianism asserts that good and evil each have their own source; they are real, independent, and eternally opposed.

This is the core of dualism: it does not shy away from the existence of evil, nor does it blame God for it. It acknowledges that evil is real, independent, and powerful—yet it simultaneously declares that evil is not final. Good and evil are not evenly matched; good is real and eternal, while evil is a temporary corruption.

2.2 The Side of Good: Ahura Mazda

At the source of all goodness stands a supreme deity.

His name is a declaration in itself: "Ahura" means "wise," "exalted," or "Lord," and "Mazda" means "wisdom." Together, Ahura Mazda is the "Lord of Wisdom."

He is not merely one of many gods; Zoroaster taught that He is the supreme, omnipotent, and only eternal God of Good. He is the all-knowing Creator of the universe, the embodiment of light, life, creation, order, and truth.

Darius the Great praised Him in his inscriptions:

"Ahura Mazda is the great god who created this earth, who created yonder sky, who created man, who created peace for man."

Zoroastrianism views Ahura Mazda as transcendent and formless, thus no images are made of Him. However, in the reliefs of Persepolis, there is a symbol often mistaken for Ahura Mazda: the winged sun disk with a human head. This is actually the Faravahar, the most famous symbol of Zoroastrianism, representing the human guardian spirit or divine glory. Its wings, disk, and feathers are rich in symbolic meaning.

2.3 The Side of Evil: Angra Mainyu

Opposing Ahura Mazda is the evil spirit, Angra Mainyu (known as Ahriman in Middle Persian).

He is the embodiment of darkness, death, destruction, and lies. If Ahura Mazda’s kingdom is one of light and order, Angra Mainyu’s domain is one of darkness and chaos. He governs earthquakes, storms, and plagues, and incites riots and wars.

A crucial theological detail regarding Angra Mainyu is that he was not created. He coexists eternally with Ahura Mazda as an independent principle in the universe.

2.4 The Crucial Theological Setting: Twin Brothers

The most unique aspect of Zoroastrian theology is the concept that Ahura Mazda and Angra Mainyu were originally twin brothers.

The implications of this are profound. It means that good and evil were not created by the same God (which would trigger the "theodicy" problem of why God would create evil), but are two independent and eternally coexisting principles.

More importantly, Angra Mainyu was not "created evil," but chose to be evil. This implies that free will precedes even the concepts of good and evil. At the very beginning, the two twin spirits made their own choices: one chose light, the other chose darkness.

This setting cleverly explains the "origin of evil," a problem that has plagued countless theologians: evil was not created by God, but was the free choice of another principle. The world is a mixture of good and evil because it is influenced by both. Yet, it also foretells the final outcome: good and evil are not equal—good is real and eternal, while evil is a temporary existence.

2.5 The Three Core Meanings of Dualism

Once you understand these twin brothers, the meaning of dualism becomes clear:

• The universe has two principles, not one. Good and evil are not two sides of the same source, but two real, independent sources.
• The universe is a war, not a completed order. The world is not a "perfect order" (where evil is just a temporary flaw), but an ongoing battle. The battlefield is the entire material world, and the timeframe is a 12,000-year cosmic cycle.
• Humans must choose a side, rather than passively accepting fate. In monotheism, where good and evil ultimately stem from God, humans need only "obey God's will." In dualism, humans are endowed with free will and the duty to choose—because the outcome of this war depends on the choices of every individual.

This is the root of the "Threefold Path" (Good Thoughts, Good Words, Good Deeds): every thought, every word, and every action is a vote for either good or evil.

III. An Inevitable Question: How Does the Good God Act Upon the World?

Dualism establishes a clear framework of opposition, but a profound theological question follows.

3.1 The Theological Dilemma

Ahura Mazda is pure light and wisdom. He is not within the material world—the material world is the battlefield He created, not His dwelling place. His realm is one of infinite light, separated from this darkness-tainted world by an ontological chasm.

Yet, the material world is the battlefield of good and evil, filled with darkness, death, and chaos.

The question arises: How does this transcendent God create, manage, and connect with the material world?

If Ahura Mazda is pure light, how does He "touch" this world polluted by evil? If He does not intervene at all, dualism becomes a passive fatalism; if He intervenes directly, how is the contradiction between transcendence and materiality resolved?

This is a question almost every transcendent religion must answer. Judaism and Christianity use the "Incarnation" (God becoming human to enter the world); Platonism uses "Emanation" (the One overflowing into the universe in layers).

3.2 The Zoroastrian Answer: Emanation

Zoroastrianism posits that Ahura Mazda connects with the material world through emanation—by manifesting His core attributes.

He does not jump into the mud directly; instead, He creates, manages, and protects the world through His "attribute-avatars."

These "attribute-avatars" are the Amesha Spentas.

3.3 What are the "Amesha Spentas"?

Amesha Spenta is an Avestan term recorded in the ancient Persian scripture, the Avesta, meaning "Immortal Holy Ones" or "Bounteous Holy Spirits."

In common terms, they are the six archangels of Ahura Mazda. Together with the "Creative Spirit" of the Lord Himself, they form the seven divine sparks.

Each Amesha Spenta is a manifestation of one of Ahura Mazda’s core attributes. They are not independent of the Lord, but are "emanations" of His attributes—much like the rays of the sun, which are both part of the sun and independently illuminate the world.

IV. The Seven Archangels: The "Operationalization" of Dualism

A millennium later, mortals were lost in the vortex of fate, their souls as restless as feathers in the wind.

The seven archangels looked down with compassion, condensing their divinity into seven-colored light cores, sinking them into the earth to become seven sacred crystals.

Each crystal is a soul contract signed between the angels and humanity:

"If you are willing to anchor yourself in virtue, the light will build a path home for you."

The core of this contract is the role of the seven archangels as a bridge between God and man. In the Zoroastrian tradition, the seven archangels are not just poetic symbols; they solve a fundamental problem: How does a transcendent God intervene in the material world? And their significance goes far beyond that.

4.1 What Problems Do the Seven Archangels Solve?

Simply put, the seven archangels do three things:

• They allow the transcendent God to "intervene" in the material world. Through them, Ahura Mazda’s will and power can operate within the world.
• They turn the abstract opposition of good and evil into a concrete, perceptible worldview. Without the archangels, dualism is just an empty philosophical proposition; with them, it gains flesh and blood, becoming a religion that can be lived.
• They provide believers with clear guidelines for action. The abstract "choose good" becomes the concrete "protect the earth," "treat animals well," and "guard the water."

The ancient Persian Avesta records that Ahura Mazda sent seven archangels to guard the order of the world. They each embody one of the seven primordial virtues, resonating with the elements of heaven and earth—fire, water, earth, metal, animals, and plants—all under their protection.

Each of these seven archangels is a ray of light emanating from the "Lord of Wisdom." They are not independent of the Lord, but are the embodiment of His attributes. They are both the personification of moral qualities and the guardians of natural realms; they belong to the heavens, yet are rooted in the earth.

4.2 Overview of the Seven Archangels

Each Amesha Spenta has three core characteristics:

• They represent a moral quality (e.g., "Good Thought," "Truth," "Piety").
• They guard a natural realm (e.g., animals, fire, earth, water, plants).
• They oppose a specific evil (e.g., evil thoughts, lies, arrogance, disease).

This is the most unique theological design of Zoroastrianism: moral attributes and the material world are unified.

• Protecting the earth is the practice of piety.
• Treating animals well is the embodiment of good thoughts.
• Guarding water sources is the pursuit of perfection.
• Worshipping the sacred fire is the witness to truth.

Thus, abstract religious ethics are grounded in concrete daily life.

V. Conclusion

5.1 Review

Let us return to the opening question: Why does the world contain both beauty and suffering?

Zoroaster’s answer is: Because the universe itself is a war between good and evil.

• The combatants: The good God, Ahura Mazda, and the evil spirit, Angra Mainyu—a pair of eternally opposing twin brothers.
• The stage: The entire material world, spanning a 12,000-year cosmic cycle.
• The human role: Endowed with free will, humans must constantly choose their side through the "Threefold Path."

But a deeper question emerges: How does the transcendent God touch this material world polluted by evil?

The answer is: Through the seven archangels—the seven-fold sparks of Ahura Mazda. They transform the abstract opposition of good and evil into a unity of moral qualities and natural realms. They are the bridge between God and man, the point where heavenly light touches the earth.

This is the core logic of Zoroastrianism: Dualism answers "why," and the seven archangels answer "how."

In this part, we have only briefly introduced the seven archangels. In the next part, we will step into the world of each angel—examining their mythological origins, their symbolic systems, and their roles in religious practice.

There is one more question we will answer there: How do these seven rays of light intertwine with "Good Thoughts, Good Words, and Good Deeds" to form a complete path of spiritual cultivation?
