Zoroaster or Zarathushtra , also referred to as Zartosht, was an ancient Iranian prophet and religious poet. The Gathas, which are the hymns attributed to him, are at the liturgical core of Zoroastrianism.
In his revelation, the prophet saw the universe as the cosmic struggle between aša which is “truth” and druj which is “lie.” The concept of aša which is only vaguely translatable – is said to be at the foundation of all other Zoroastrian doctrine, including that of Ahura Mazda (who is aša), creation (that is aša), existence (that is aša) and Free Will. This is said to be Zoroaster’s greatest contribution to religious philosophy.
The purpose of humankind, like that of all other creation, is to sustain aša, the truth through active participation in life and the exercise of good thoughts, words and deeds.
