Fravashi (fravaši, /frəˈvɑːʃi/) is the spirit of an individual, whether dead, living, and yet-unborn, sending out the 'soul' into the material world to fight the battle of good versus evil. The 19th day of the 1st month of the year (in the Zoroastrian Calendar) is dedicated to observing farvardin jashan. 

Asha Vahishta (Avestan: Excellent Order, or Truth) is the second of the six primeval creations realized by Ahura Mazda. He presides over fire, sacred to the Zoroastrians as the inner nature of reality. To the devotee he holds out the path of justice and spiritual knowledge. 

Haurvatat (haurvatāt) is the Avestan language word for theZoroastrian concept of "wholeness" or "perfection." In post-Gathic Zoroastrianism, Haurvatat was the Amesha Spenta associated with water, prosperity, and health.

Vohu Manah, (Avestan: “Good Mind”), was created by Ahura Mazdā to assist him in furthering good and destroying evil. According to Zoroastrian doctrine, because the prophet Zoroaster was, in a vision, conducted into the presence of Ahura Mazdā by Vohu Manah, any individual who seeks to know the Wise Lord must approach him through this immortal.

Amərətāt (Immortality) is the Amesha Spenta of long life on earth and perpetuality in the hereafter. 

Khshathra Vairya (Desirable Dominion), who presides over metal, is Amesha Spenta who personifies Ahura Mazdā’s Divine Power and kingdom and guides the believers to purity and freedom from evil. 

Spənta Ārmaiti (Holy Devotion) guides people to good life and salvation.
