A Modern Zoroastrian is a discussion of the principle of polarity in nature, with special reference to the doctrines of Zoroaster.

The Avesta /əˈvɛstə/ is the primary collection of religious texts of Zoroastrianism, composed in the otherwise unrecorded Avestan language. The Avesta Selections is a part of "The Library of the World's Best Literature, Ancient and Modern". It is a work of enormous proportions. Setting out with the simple goal of offering "American households a mass of good reading", the editors drew from literature of all times and all kinds what they considered the best pieces of human writing, and compiled an ambitious collection.

Pahlavi Texts Part 2 contains the ninth-century Dâdistân-î Dînîk and Epistles of Mânûskîhar. They are religious judgments or decisions given by Mânûskîhar, a high priest of Iran, in answer to ninety-two queries put to him by fellow Zoroastrians.

This is part IV of the Sacred Books of the East translation of the Pahlavi Texts of Zoroastrianism. There is a legend that after Alexander the Great conquered Persia, a huge amount of Zoroastrian literature disappeared. In this volume West presents what is known about a number of fragmentary Zoroastrian texts, some only known by name, including summaries, digests, and stray quotes from other books.

This is part V of the Sacred Books of the East Pahlavi Texts translation. This volume contains translations of a number of very late Zoroastrian texts, some prophetic in nature, others providing clues to the chronology of the religion. As such, the texts here, the Dinkard and Selections of Zad-Sparam, make interesting reading. They will be of use both to scholars looking for information about the development of Zoroastrianism, and those looking for non-traditional books of prophecy.

This is part I of the Sacred Books of the East Pahlavi Texts translation. It includes a number of crucial medieval Zoroastrian texts: the Bundahis, Selections of Zad-sparam, the Bahman Yast, and the Shayast la-Shayast, as put into writing about the sixth century C.E.

Pahlavi Texts Volume 3 contains the Dînâ-î Maînôg-î Khirad ('Opinions of the Spirit of Wisdom' - a series of enquiries and answers relating to the worship of Ahura Mazda); the Sikand-gûmânîk Vigâr ('Doubt-dispelling Exposition' - a controversial ninth-century Zoroastrian apologetic, designed to prove the correctness of the fundamental doctrine of Mazda-worship); and the Sad Dar, a Persian rather than Pahlavi text, offering valuable discussion of 'a hundred subjects' connected to Zoroastrianism.

The Gathas are 17 Avestan hymns that are believed to have been composed by Zoroaster himself. The Gathas form the core of the Zoroastrian liturgy, the Yasna, in which they are the oldest and most sacred sections.

This is a short study of the Zoroastrian religion, part of the Wisdom of the East series. S.A. Kapadia, who along with L. Cranmer-Byng, edited or wrote many of the books in the Wisdom of the East, was a member of the Indian Zoroastrian community, and his personal insights into the religion are invaluable.

The “Yatkar-i-Zariran,” purports to tell of the old religious wars of Zoroaster's time, and recounts the heroic deeds of a champion named Zarir, whom Firdausi also mentions, but who is otherwise unknown. Doubtless this very Yatkar or some older version of it was among the sources to which the poet Firdausi appealed in writing his “Shah-Nameh.”
