Zoroastrians believe there is an eternal battle between good and harm in the world. Everybody is responsible for fighting evil, on both an intellectual and physical level. Zoroastrians believe that God created mankind and is the creator of the universe. So, they view themselves as fellow soldiers in the fight against evil.
Two types of time
In Zoroastrianism, time is divided into two types: daily and weekly. The first is the sacred day. The latter is the period for the dead. Zoroastrians believe the dead can have an effect on the living. These spirits can bring luck and prosperity or hardships and sickness. They offer special animal sacrifices and wine as offerings to these spirits.
One
Zoroastrianism is a religion focusing on one God. While many of its beliefs can be compared to Christianity, the idea of one God is not universal. The concept of one God was actually developed by the Hebrew people, more than a thousand years prior to the foundation of Zoroastrianism. For example, the prophet Isaiah mentioned Christ's virgin birth around 701 BC. This predates Zoroastrianism by a hundred years.
Purity
Zoroastrianism holds the importance of purity. It refers to the belief that the creation of Ahura Mazda is perfect and that we should not defile it. In practice, this means Zoroastrians have avoided burial or cremation in the past. Instead, they laid their dead bodies at the Tower of Silence. Here, vultures ate them.
Goodness
Zoroastrianism believes that goodness is an important concept. Zarasthura the founder Zoroastrianism was a believer in the threefold path. This path is analogous with the "law and love" in Christianity. It teaches the importance to make wise decisions based on God's intentions. Zoroastrianism emphasizes goodness over purely good. Its doctrines can be found in many different religions, despite its similarities to Christianity.
