Zoroaster is a generic title; and so is self-created Thoth-Hermes. There were several prophets of those names. Zoroaster was the founder of Magian religion and reformer of Magic, as practiced by the Chaldeans and the old Egyptians, but not the founder of Divine Magic or Theurgy.
Apuleius asserts that Zoroaster instructed Pythagoras. Socrates saluted the rising sun, as does a true Parsi or a Zoroastrian today.
Solus-Sol-Sun is “The One” and “The Most High” (Helios). But there is a great difference between our sun and its prototype — the Central Spiritual Sun. The Zoroastrian Esotericism is identical with the Occultism of Theosophy, and the Universal Secret Doctrine.
Kalahamsa, the “Swan of Time,” is coequal with the Zoroastrian “I am that I am.” The Chaldean Divine Dynasties appear in succession over a cycle of 432,000 years.
Part 2. The Chaldaean Oracles of Zoroaster.
(A) Emanations of the Unknowable Causeless Cause of Spirit and Matter.
(B) Ideas, Ideals, Ideation.
(C) One Universal Soul, periodical souls, and those chained to bodies.
(D) Matter is the shadow of Light and vehicle of Life. Matter manifests the finest spiritual ideations only to the pure in heart.
