SCRIPTURES OF ZOROASTRIANISM
Zoroastrianism is an ancient Aryan religion that originated in Persia more than 2500 years ago. Though it has relatively few adherents, about one hundred and thirty thousand in the whole world, it is one of the oldest religions. Zoroaster was the founder of Zoroastrianism in the religion of Persia(or Faras) Iran, also commonly known as Parsi-ism. It is also known as the religion of fire worshippers and Magianism.
Parsi Scriptures consist of Dasatir and Vesta or Zend-Avesta. Dasatir is further divided into two parts: Khurda Dasatir and Kalan Dasatir.
Some Parsis consider the Zend Avesta to be more authentic than the Dasatir while the others consider Dasatir to be more authentic.
Zend Avesta is divided into three parts
Dasatir means a book of ten parts: ‘Das’ meaning 'ten' and ‘tir’ meaning ‘a part’. Dasatir is also the plural of Dastur, which means law or religious code.
