Zoroastrian Theology’s salient principles cover the gamut of his teachings.  This summary reflects his religious beliefs that range from God’s guardianship, purity, health care, charity, virtue, nature, and the immortality of the soul.

1. Much of the Zoroastrian theology is directed towards the protection of mankind to fight against Angro Mainyus and his wicked accomplices.
2. Careful instructions are given concerning the care, and burial of the dead.
3. Purity is stressed. Information is given about germs, and the preservation of public health.  This also concerns the good thoughts, words, and works.  The purification of one’s body was essential, as well as that of the corporeal world.
4. Believers learn about the commands to cultivate the soil, irrigate the land, and care for livestock.
5. Strict ordinances are meted out for the care and welfare of women during gestation, and child birth.
6. Two attributes were seen as inherent in men and women – “Vohumana” (Good Mind), and “Akamana” (Evil Mind). This moral philosophy is expressed in these expressive words – “Humata” (good thoughts), “Hukhta” (good words), and “Hvarshta” (good deeds).
7. Zoroaster considers as wise the distribution of charities to the sorrowful, and to those with untold miseries.
8. Marriage is recommended because it leads to a religious and virtuous life.
9. Chastity and implicit obedience from a wife to her husband are viewed as the greatest virtues in a woman. This breach will be punished as a sin.
10. Great tolerance is shown in passing judgment on the religious beliefs of others.
11. Abortion is a grave sin when a partner or parents attempt to hide the shame from the world.
12. Zoroaster placed the whole creation under the guardianship of God, and six “Ameshaspends” (archangels). These are mystical guardian spirits who work night and day for the welfare and protection of the creation that are committed to their charge by the Almighty.  These archangels are responsible viz., for domestic animals and birds; fire and life-giving heat; all kinds of metals and minerals; injunctions to keep the earth fruitful, clean, and cultivated; the purity of water and water-courses; and trees and vegetation.  These duties are done through the assistance of Yazats (angels), who police and guard the earth night and day against the encroachments of Angro Mainyus (Evil Spirit).
13. Special legislation is laid down for the treatment of the lower animals, the elimination of pain, and unnecessary suffering.
14. Unlike other religions Zoroaster condemns fasting or the total abstinence from food as foolish and injurious to the body.
15. Zoroastrianism gives evidence to the great belief of immorality of the soul, and the resurrection of the body. At the Great Gathering everyone will be judged, the battle will end, and the Evil Spirit will no longer have power to play man as a pawn.  And there will be everlasting peace and happiness.
