During life, the fravashi act as aspirational concepts, spiritual protectors, and the fravashi of bloodline, cultural, and spiritual ancestors and heroes are venerated and can be called upon for aid.
On the fourth day after death, the urvan is reunited with its fravashi, in which the experiences of life in the material world are collected for the continuing battle in the spiritual world.
Prior to being born, the urvan (soul) of an individual is still united with its fravashi (personal/higher spirit), which has existed since Ahura Mazda created the universe.
Scholars and theologians have long debated on the nature of Zoroastrianism, with dualism, monotheism, and polytheism being the main terms applied to the religion.Zoroastrianism is a heterodox faith, meaning it is not uniform in theological and philosophical thought, especially with historical and modern influences having a significant impact on individual and local beliefs, practices, values and vocabulary, sometimes merging with tradition and in other cases displacing it.In Zoroastrianism, the purpose in life is to become an Ashavan (a master of Asha) and to bring happiness into the world, which contributes to the cosmic battle against evil.In Middle Persian literature, the prominent belief was that at the end of time a savior-figure known as the Saoshyant would bring about the Frashokereti, while in the Gathic texts the term Saoshyant (meaning "one who brings benefit") referred to all believers of Mazdayasna but changed into a messianic concept in later writings.
Zoroastrian theology includes foremost the importance of following the Threefold Path of Asha revolving around Good Thoughts, Good Words, and Good Deeds.
This active participation is a central element in Zoroaster's concept of free will and Zoroastrianism as such rejects extreme forms of asceticism and monasticism but historically has allowed for moderate expressions of these concepts.
