পারসী ধর্মের প্রধান ধর্মগ্রন্থের নাম কী ?
The most important texts of the religion are those of the "Avesta", which includes the writings of Zoroaster known as the Gathas, enigmatic poems that define the religion's precepts, and the Yasna, the scripture. The full name by which Zoroaster addressed the deity is: Ahura, The Lord Creator, and Mazda, Supremely Wise. The religious philosophy of Zoroaster divided the early Iranian gods of Proto-Indo-Iranian tradition, but focused on responsibility, and did not create a devil per se. Zoroaster proclaimed that there is only one God, the singularly creative and sustaining force of the Universe, and that human beings are given a right of choice. Because of cause and effect, they are responsible for the consequences of their choices. The contesting force to Ahura Mazda was called Angra Mainyu, or angry spirit. Post-Zoroastrian scripture introduced the concept of Ahriman, the Devil, which was effectively a personification of Angra Mainyu.
