When he was thirty years old, Zarathushtra left the cave for his home town while in his vision, he perceived Ahura Mazda as the Wise Lord of Creation, and the seven emanations of Ahura Mazda, the Amesha Spentas as the guardians and artisans of this physical world. He perceived the laws upon which the universe operated, and understood the inter-relationship between Ahura Mazda, the Amesha Spentas, and the Creation.
After his illumination, Zarathushtra wanted to share his acquired wisdom with the world. He made a decision to invite all his family and relatives to listen to his teachings. And then in a family gathering, he explained his understandings to them.When he finished explaining, his cousin, Maedyoimaha, decided to join him, and became the first follower of his teachings. And his wife Hvovi also embraced his teachings becoming his second follower. His children, one by one, decided to accept his religion which was called GOOD RELIGION by himself.
Zarathushtra then decided to share his teachings with his fellow citizens. When he started teaching others in the street of the city, he met with a deeply rooted resistance from the priests, who had based their entire life and livelihood on the old religions. Zarathushtra tried many different techniques, and every time he met with renewed opposition and greater resistance. In fact, over the next twelve years, he only managed to win 22 people over to his religion, including his wife and children, and his first disciple, his cousin.
Having met such frustration, and such vehement opposition from the rulers and priests of his own land, he decided to leave his homeland for other countries. He then mobilized his followers, and the group of 23 people started their migration.
To whichever land they came, and in whatever city that stayed, he tried to teach others about his religion, yet in every place they met with predictable opposition, partly due to the self-interested preemptive strikes of the rulers and priests, and partly because of the ignorance of the people, and their unwillingness to change.
Finally, they had heard that a King of a nearby country, King Vishtaspa, was a wise man and if there was one person in the whole world who might be open to listen to new teachings, it would be him. And they set off in that direction.
Zarathushtra was 42 when he and his followers finally reached the court of King Vishtaspa. The wise King had granted Zarathushtra an audience, but he had also invited all the priests and wise men of his court to attend and listen to Zarathushtra and question him about his religion. The King had wisely set the scene for a debate, if it need be.
At the debate in the court of King Vishtaspa, Zarathushtra eloquently spoke and convincingly responded to all challenges and questions. The King saw the wisdom of this man, and his teachings and embraced the religion. At the same time, the King invited his subjects to also listen carefully and choose wisely to follow the Zoroastrian religion. This was a major breakthrough for Zarathushtra.

However, the story goes on to say that Zarathushtra’s enemies then plotted against Zarathushtra and planted various objects of black magic in his quarters, and finally by accusing him of such evil acts, prompted the King to search his room. Upon finding such artifacts, Zarathushtra was imprisoned and denied to eat or drink.
Yet the story has a favorable turning, as such stories inevitably do. It is said that the King’s favorite dark horse is struck with an incurable deforming disease. None of the physicians in the kingdom can offer any cure. When Zarathushtra, who was now in prison, hears about this, he offers the King to try to cure his favorite horse.
The King reluctantly lets Zarathushtra attempt his healing techniques, which he duly does. The King then realizes the error of his judgment about Zarathushtra, and embraces his religion. The King also punishes the priests who conspired against Zarathushtra, and starts to promote the religion.
Once the King embraced the religion of Zarathushtra, it was a breakthrough and a turning point in the fortunes of the Zoroastrian Religion. From that time on, Zarathushtra had the backing and support of a powerful and wise King. He freely went about propagating his teachings throughout that land, and very soon his message crossed the borders of the country to neighboring countries. In a way, if Zarathushtra’s illumination was the conception, this was the birth of the Zoroastrian Religion, as we know it today.
Two of the earliest converts, after King Vishtaspa embraced the religion were two brothers named Frashaoshtra and Jamaspa, of the Hvogva family. These two are mentioned in the Gathas, and they continued to be among Zarathushtra’s disciples until the end.
There is yet another legendary story about a tree that Zarathushtra allegedly planted. It is also mentioned in the Shahnameh that when Zarathushtra visited Kashmar, he planted a Sarv (Cyprus tree). This tree which became famous as Sarv-e Kashmar, is claimed to have grown for millennia, from the time of Zarathushtra until it was ordered to be cut down by Caliph al-Mutawaqqil, in the year 861 CE.
The Shahnameh of Ferdowsi says that in the seventy seventh year of his life, Turanian army had captured King Vishtaspa’s land. The Turanian army then entered the fire-temple, where they massacred eighty priests who were at prayer. Zarathushtra was also there at the time of prayers, and was attacked by the dagger of Turbaratur (Bratrakarash), and was martyred there on the spot.
