Name one sacred text of Zoroastrianism.

The Avesta is indeed the sacred text of Zoroastrianism and serves as the primary scripture for followers of this ancient religion founded by the prophet Zoroaster (or Zarathustra). It contains a collection of hymns, rituals, and teachings central to Zoroastrian beliefs, including prayers known as the Gathas, which are attributed to Zoroaster himself. The Avesta outlines the core tenets of Zoroastrianism, such as the concepts of dualism (the struggle between good and evil), the importance of individual choice, and the notion of an afterlife.

In contrast, the other texts mentioned are central to different religious traditions. The Bible is the sacred scripture of Christianity, while the Vedas are the foundational texts of Hinduism. The Guru Granth Sahib is the revered scripture of Sikhism. Each of these texts carries profound significance within its respective faith but does not pertain to Zoroastrian beliefs or practices.
