Zoroastrianism has a number of important beliefs. One is the belief that all God's creations are pure. Zoroastrians are careful not to degrade forests or pollute rivers. In fact they are often called "the first ecological religion".
Ahura Mazda
Zoroastrianism is centered on the concept of Ahura Mazda's immanence within man. According to the religion, every human being possesses a Fravashi, a spiritual element that embodies God. This element can heal, prevent evil, and inspire piety.
Ahura Mazda can be described as the highest Zoroastrian deity. He is also the Yasna’s original spirit. His name means "wisdom." Although some religions may seem contradictory, there is also a lot in common.
Dualism
Persia's earliest examples of dualism are well-known, and zoroastrianism follows suit. The renowned philosopher zoroaster explained in his work that dualism was an important philosophical principle. Dualism is a Zoroastrianism concept that relates ontological as well as ethical questions.

Early Zoroastrianism has been called a form of dualist monotheism. The belief system has also been compared to other monotheistic worldviews. The Angra Mainyu are evil by choice and nature, which is a key issue in the debate.
It is our duty to resist evil
Zoroastrianism holds that it is a person's responsibility to fight evil. The religion emphasizes social justice as well as human rights. It believes humans are fellow workers in fighting evil and must be kind to others. They also believe that all humans are born free and will be punished in the afterlife if they do not fulfill their religious duty.
Zoroastrianism's Cosmology teaches us that good and evil exist, just as the two power Ahura Mazda (and Angra Mainyu) are in opposition. 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.
Duty to care for the good
According to Zoroastrianism, the duty to care for the good is a fundamental part of a person's life. The religion stresses the importance to do good deeds, avoid sin, and ensure the well-being of the entire world. It also stresses the need of caring for the earth and children. So, people can take care of their responsibility to the greater good of the planet.
Two principles are found in Zoroastrianism: Ahura Mazda, the creator of the universe, is all-good, and Ankhra Mainyu who is the antithesis to Ahura Mazda. The history is a struggle between good and wicked. A vision also shows Ahura Mazda appearing to Zoroaster.

Charitable giving
Zoroastrianism refers to a benevolent religion which practices charitable giving. Zoroastrians gave legacies to religious foundations and sacred flames during the Sasanian Period. They registered their foundations in the Muslim authorities as waqfs. These foundations became legally inalienable. Administrators were entitled to a part of the income.
Faith teaches that every human being has a duty to assist those in need. Charity is a noble act that can help to make amends for sins and save the soul. Pursisniha 44 explains that the souls who give charity are elevated in heaven.
