Zoroaster saw the human condition as the mental struggle between asa, which means truth, and druj meaning lie. Asa is very intricate and only vaguely translatable, but it deals with the creator, creation and existence.
Our purpose, as any creation, is to sustain asa. This is exercised throughout life through the use of constructive thoughts, words and deeds.
In 2005, the Oxford Dictionary of Philosophy ranked Zarathustra as first in the chronology of philosophers. Zarathustra influenced modern day thought by influencing the ancient Greeks. He himself dated back to around 1000 B.C. and came up with the word Mazda-Yasna, which means”the worship of wisdom.” Later, his followers, Zoroastrians, educated greats like Pythagoras, who is the person credited with coining “philosophy,” which means the lover of wisdom.
Zoroaster put a special emphasis on the individual’s personal right to exercise their freedom to either choose to accept asa (truth) and ignore druj (ignorance/chaos), or give into druj and therefore isolate themselves from asa. Because truth can see through ignorance, because it is about it, but ignorance cannot see truth, for it ignores it.
Zoroaster taught that if we have good thoughts, good works, and good deeds, then we were not slaves but became co creators of both the world and ourselves.
