Good thoughts, good words, good deeds — the oldest war on evil.
The religion of Zarathustra: one wise Lord, a real adversary, and every human drafted into the war between truth and the lie by their own choices. Its endgame — judgment, resurrection, a world made new — became the template the Abrahamic faiths inherited.
DeitiesAhura Mazda alone is worshipped, and the tradition is emphatic that he did not make evil — Angra Mainyu is an uncreated opponent, not a subordinate. Beneath Ahura Mazda stand the six Amesha Spentas, who are attributes of him and also persons, each with a piece of creation in their care; below them the yazatas, beings worthy of worship, of whom Mithra, Anahita and Sraosha have the largest followings. Whether this is monotheism, dualism or something the categories do not fit has been argued since the Greeks, and Zoroastrians generally answer that it is monotheism with a real enemy.

Ahura Mazda did not make evil.
This is the point of the whole system. Evil is not a test, not a permitted shadow and not part of a larger plan — it is an uncreated hostile intelligence that got in. The cost is that God is not omnipotent in the way later monotheisms would want; the benefit is that the problem of evil does not arise.

Existence is a war between truth and the lie.
Asha against druj: Ahura Mazda's good creation is contested by a real adversary — and the war has a winner.

The world is good, and enjoying it is correct.
Matter is not a trap and the body is not a prison. There is no fasting from food, no celibacy, no monasticism and no virtue in poverty. The tradition treats gloom as collaboration with the enemy and holds that a person who weakens themselves has removed a soldier from the field.

Every person is drafted by their choices.
Good thoughts, good words, good deeds — free choice is the battlefield; neutrality is not on offer.

The Bridge of the Separator.
Three days after death the soul comes to a bridge, which widens for the good and narrows to a blade's edge for the wicked. The thoughts, words and deeds are weighed by Mithra, Sraosha and Rashnu, and the soul meets its own conscience — beautiful or hideous, depending on what it has been doing.

The end is renovation.
Frashokereti: evil defeated finally, the dead raised, the world made fresh — the template later apocalypses inherited.

In the end everyone is saved.
The developed eschatology has the dead raised, the whole of creation passed through a flood of molten metal — pleasant as warm milk to the good, agonising to the wicked — and then all souls, including those in hell, restored. Evil is not merely defeated but abolished, and hell empties.

A corpse is the greatest pollution there is.
Death is the enemy's clearest victory, and a dead body is where his power is densest. It may not be given to fire, which is sacred; nor to water; nor to earth, which it would defile. Hence exposure — the one method that pollutes nothing.

You are choosing, right now.
The Gathas repeatedly address hearers as people who must decide between two ways, and insist the choice is real and unforced. There is no predestination, no inherited guilt and no original sin. A child is not accountable until initiation, and after it everything counts.

Asha — truth, rightness and the order of things, in one word.
It covers the truth of a statement, the rightness of an act and the regularity of the seasons at once, because the tradition takes these to be the same thing. Its opposite, druj, is the lie — which is likewise a moral failure and a disorder in the world, not merely a false sentence.

Six creations, six guardians.
The Amesha Spentas are attributes of Ahura Mazda and also persons, and each has a piece of creation in their charge: sky, water, earth, plants, cattle and humanity. Caring for those six things is therefore not stewardship in the modern environmental sense but direct service to a divine being.

Zarathustra.
A trained priest who became a critic of the priesthood, working in eastern Iran or Central Asia somewhere between 1500 and 600 BCE — the range is that wide and the argument is unresolved. He is not divine, is not prayed to, and in the Gathas complains about having no cattle and no men.

Ahura Mazda — the Wise Lord.
Uncreated, all-good creator of the good creation — worshipped through fire, which is his visible sign, not his image.

T
The Bounteous Spirit.
In the Gathas the two twins who choose are Spenta Mainyu and Angra Mainyu, and Ahura Mazda is the father of neither choice — a distinction that keeps God out of the pairing. Later theology identified Spenta Mainyu with Ahura Mazda himself, which made the dualism cleaner and the Gathic text harder to read straight.

Angra Mainyu — the lie.
The destructive spirit, source of every corruption: a real adversary, but a doomed one — the war ends, and he loses.

The kusti prayer, five times a day.
Wash, untie the cord, hold it while reciting the rejection of the lie and the confession of faith, retie it with four knots. It requires no building, no priest and no congregation, and it is the whole of daily obligation. The words are Avestan, a language dead for two millennia, and most people learn them by sound.

Kusti — the tied cord.
Seventy-two threads untied and retied with prayers, several times a day — the faith worn on the body.

Navjote.
Between about seven and fifteen the child is bathed, recites the confession of faith, and is invested with the sudreh shirt and the kusti cord in front of the community. Before it a child bears no moral responsibility; after it they answer for their own choices. The entire theology is compressed into that transition.
