Zoroaster, also known as Zarathustra, was an ancient Iranian prophet and religious leader who founded Zoroastrianism, one of the world's oldest known religions. His teachings are contained in the sacred texts known as the Avesta.

The Avesta is the primary scripture of Zoroastrianism and consists of a collection of hymns, prayers, rituals, and philosophical treatises. It is written in Avestan, an ancient Iranian language. The Avesta is divided into several sections, including the Yasna, Visperad, Vendidad, and Khorda Avesta.

The teachings of Zoroaster found in the Avesta cover various aspects of life, spirituality, and ethics. Here are some key teachings:

1. Dualism: Zoroaster's teachings revolve around the concept of a cosmic struggle between good and evil. He believed in the existence of two opposing forces, Ahura Mazda (the Wise Lord) representing good and Angra Mainyu (the Destructive Spirit) representing evil.

2. Monotheism: Zoroaster taught the worship of Ahura Mazda as the supreme deity. He emphasized the importance of ethical behavior and the pursuit of righteousness in order to align oneself with the divine.

3. Moral Code: Zoroaster laid out a moral code known as the Asha, which encompassed concepts like truthfulness, justice, kindness, and the rejection of violence and dishonesty. He emphasized the importance of personal responsibility and the consequences of one's actions in the afterlife.

4. Judgment and Afterlife: Zoroaster taught the belief in an individual judgment after death, where one's actions and choices in life would determine their fate in the afterlife. Those who followed the path of righteousness would be rewarded, while those who chose evil would face punishment.

5. Rituals and Prayers: The Avesta contains numerous rituals and prayers that were to be performed by Zoroastrians. These rituals were aimed at maintaining purity, seeking divine blessings, and honoring the divine entities.

In conclusion, Zoroaster's teachings are contained in the Avesta, the sacred texts of Zoroastrianism. These teachings encompass concepts of dualism, monotheism, morality, judgment, and the afterlife, and are aimed at guiding individuals towards a righteous and ethical way of life.
