Zoroastrians believe there is an eternal battle between good and harm in the world. It is everyone's duty to fight evil, on both a physical and spiritual level. Zoroastrians believe that God created mankind and is the creator of the universe. In this way, they see themselves as fellow workers in this battle.
There are two types of time
Zoroastrianism is divided into two types of time: 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 may bring you prosperity and fertility, or can cause hardships and sickness. They offer offerings to these spirits in the form of wine, milk, pomegranates, quinces, and sometimes special animal sacrifices.
One God
Zoroastrianism is a religion that focuses on one God. Although many of its beliefs are similar to Christianity, the concept of one God is not universal. In fact, the Hebrew people invented the concept of one God more than a thousand centuries before Zoroastrianism was founded. For example, the prophet Isaiah mentioned Christ's virgin birth around 701 BC. This predates Zoroastrianism by a hundred years.
Purity
Zoroastrianism believes that purity is an important concept. It is the belief that Ahura Mazda was created perfectly and we should respect that. This is what Zoroastrians believe in practice. They have avoided burial and cremation for centuries. Instead, they bury their dead at the Tower of Silence. Vultures then eat them.
Goodness
Goodness is an important concept in Zoroastrianism. Zarasthura, the founder of Zoroastrianism taught his followers to follow the threefold path. This path is an analogy to Christianity's "law in love," which teaches how important it is to seek God’s guidance and make wise choices. Zoroastrianism emphasizes goodness over purely good. Its doctrines can be found in many different religions, despite its similarities to Christianity.
