Zoroastrianism has a number of important beliefs. One is the belief that all God's creations are pure. Zoroastrians do not destroy forests nor pollute rivers. In fact, they are often called the first ecological religion.
Ahura Mazda
Zoroastrianism has its core concept in Ahura Mazda's manifold immanence. Fravashi, which is a spiritual element, is believed to be a part of every human being. This element has the ability to heal, ward off evil, and inspire piety in humans.
Ahura Mazda, Zoroastrianism’s highest deity, is Ahura Mazda. He is also the Yasna's first spirit. His name means "wisdom." Although some religions may seem contradictory, there is also a lot in common.
Dualism
Persia was the first to demonstrate dualism. Zoroastrianism also has some examples. Famous philosopher zoroaster explained how dualism is an important philosophical principle in his works. Dualism is a Zoroastrianism concept that relates ontological as well as ethical questions.

Early Zoroastrianism is often referred to as a form dualist monotheism. This belief system has been compared with other monotheistic worldviews. One of the most controversial issues is the Angra Mainyu. They are believed to be evil by choice and nature.
Duty to oppose evil
Zoroastrianism says that one's duty is not to support evil. It emphasizes human rights and social justice. It believes that humans are fellow workers in the struggle against evil and must therefore treat others with care. They believe that all humans are born in freedom and will be punished in their afterlife for failing to perform their religious duty.
The cosmology of Zoroastrianism teaches the existence of good and evil, as the two powers Ahura Mazda and Angra Mainyu are opposed in the universe. In the world, Ahura Mazda is the god of light and wisdom, and Angra Mainyu is the god of evil and destruction. Zoroastrians believe that the god Ahura Mazda protects the universe from evil, but the evil force Angra Mainyu is responsible for the earth's decay and natural disasters.
Obligation to take care of the good
Zoroastrianism says that one must care for the common good as a fundamental part in his or her life. The religion stresses the importance to do good deeds, avoid sin, and ensure the well-being of the entire world. It emphasizes the need to care for the land and children. This is how a person fulfills his or her responsibility for the good of the entire world.
Zoroastrianism has two principles. There is Ahura Mada, who is the creator and all-good deity, and there is Ankhra Mainyu (the evil deity). The history of the world has been a battleground for good and evil. Visions also reveal that Ahura Mazda appears in visions to Zoroaster, the prophet.

Charitable giving
Zoroastrianism practices charitable giving. Zoroastrians left legacies in the Sasanian period to sacred fires, pious foundations, and other charitable causes. Their foundations were registered as waqfs by Muslim authorities. The property in these foundations became legally inalienable and the administrators were entitled to a share of the endowment's income.
The faith teaches us that all human beings have a responsibility to help others in need. Giving charity is a virtuous act of self-giving that can forgive sins or contribute to the salvation and enhancement of the soul. Pursisniha 44 states that the soul of a charity person is elevated in heaven.
