Explanation
The holy book "Avesta" is associated with the Parsi religion. Zoroastrianism is the ancient religion of the Persian people and Parsis are the followers of Zoroastrianism who migrated from Persia (Iran) to India in the 8th and 10th centuries CE, due to religious persecution in their homeland. The Avesta is the primary sacred text of Zoroastrianism and contains hymns, prayers, and teachings that were compiled over many centuries and preserved by Zoroastrian priests. The text is written in an ancient language called Avestan and is revered by Parsis as a source of spiritual guidance and wisdom.
