Zoroaster was a Bronze-Age rock star.
He was most likely Scythian. I am sure the best musicians and dancers would have been drawn to his ceremonies.
Unlike the mythical Moses and Jesus, Zoroaster really walked the earth and left his best songs as proof. The truly spiritual among us are gifted with the greatest talents, and Zoroaster was the greatest rock star of his time.
Zoroaster had a revelation one day while stepping out of a stream while wondering why the hell was there was so much evil in the world?
Boom!!!!!!!!!!!
Rather than a complex pantheon of gods like everyone thought, there must be an all-powerful and perfect vibe that created the universe!
But because all life is duality, the goodness and perfection of the good vibe, the force that had created everything, had to be balanced by an opposing force, the bad spirit, which had been tiny at creation, but got a foothold after the first human couple got infected by it. After people invented money and got super greedy and self-centered, and turned into murderous cut-throats, the bad spirit had gotten more powerful than the good vibe.
To remedy the situation, Zoroaster’s songs suggested “good thoughts, good words, good deeds,” in order to create ripples on the cosmic plain to dampen the bad spirit.
Zoroaster also sang about the sun (Mithras) and about Haoma (bhang).
His ceremonies were done outside, typically at some epic feng shui location, in the Scythian manner.
One song told of how there would be a zombie apocalypse one day and all the dead would rise and be forced to walk across Shinvat Bridge.
If they had good karma, the bridge would be wide but if they had mostly bad karma, it would shrink to the width of a knife blade, sending them spiraling down into the Valley of Lies forever.
Zoroaster also sang about how one day in the future, another great singer like him, a messiah, would emerge to usher in the zombie apocalypse.
The performances were designed to encourage people to become more empathetic and ethical, but that was a “boom!” heard round the world because it blew into Judaism, Christianity and Islam.
