Welcome, Zoroastrianism
“That nature alone is good which refrains from doing to another whatsoever is not good for itself.”
— Dadistan-I-dinik 94:5
Zoroastrianism may be the oldest religion to state the passive Golden Rule explicitly. Zarathustra taught that reality is a choice between asha (truth) and druj (falsehood) — and the Ultimate Law agrees: logic is the supreme rule, and deception is a form of harm. The Faravahar depicts a human figure choosing the path of good thoughts, good words, good deeds — not because a god commands it, but because asha is the structure of reality itself. Three thousand years before the dictionary was written, Persia already knew.
The Ultimate Law
Logic is the ultimate law.
Do not do to others what they would not want to be done to them, or you will be punished regardless of your will.
The purpose of punishment is to erase guilt, via retribution and restitution.
That is the entire law; it cannot be changed, all the rest is commentary.
