Zoroastrianism is a religion founded by a priest called Zarathustra Spitma or Zoroaster as far back as 1200 BC, with the primary belief of an omnipotent God or "the One" Ahura Mazda and the context of a cosmic battle between the forces of good and evil. During the era before Zoroastrianism, the Persians (known today as Iranians) believed in the polytheistic religion. It is believed that many social problems had occurred in this era due to these beliefs and practices. At the same time, Zoroaster was born into a family with a father named Pourushaspa and a mother named Dughdova. At the age of twenty he left home and, after many years spent searching for the right religion, he finally found a purification festival. Zoroaster descended into the river to purify himself and had a vision of Vohu Mannanh who led him to the almighty Ahura Mazda. This was the time when Zoroaster heard the teaching of Ahura Mazda, was blessed, and became the prophet of Zoroastrianism. Initially, Zoroaster struggled with the new faith trying to convince people to accept his religion. He called upon the almighty Ahura Mazda for help and inspiration before fleeing his homeland to preach his teachings in the neighboring land of Bactria, the land of the Ruler called Vishtaspa. Zoroaster's teachings had impressed the king who was so pious that he made Zoroastrianism the state religion. Under the influence of the pious king, the beliefs and practices of Zoroastrianism were widely spread to many other parts of Iran. However, during his preaching in Bactria, Zoroaster was murdered and died at the age of seventy-seven. In 331 BCE Alexander the Great conquered Iran. Many temples, priests and sacred scriptures were destroyed. Fortunately, in the center of the paper, the ching indicates the basic practices for performing good deeds, practicing good thoughts and speaking good words. By improving these good deeds we create a world that is said to be non-violent and non-suffering, a world we can call paradise. Bibliography: Haug, Martin, Edward William West and EP Evans.
