What is the name of the Amesha Spenta representing immortality?

Ameretat is the Amesha Spenta representing immortality in Zoroastrianism.

Ameretat is the Avestan form of a divine name meaning “immortality” or “not dying.” The Amesha Spentas are the beneficent immortal beings who express major aspects of Ahura Mazda’s creative and moral order. Ameretat is traditionally associated with plants, growth, and the preservation of life, making immortality an active principle in the living world rather than merely an abstract promise after death.

Ameretat is commonly paired with Haurvatat, the Amesha Spenta representing wholeness or completeness. Their association reflects a broader Zoroastrian pattern: spiritual qualities are connected with elements of creation. Haurvatat is linked with water, while Ameretat is linked with plants and nourishment.

The name can appear in different forms across languages and periods, including Amurdad in Middle Persian and later Persian usage. This variation can make the answer look unfamiliar, but Ameretat is the standard Avestan form used in English reference works. Ameretat should not be confused with Asha Vahishta, associated with truth and righteousness, or Vohu Manah, associated with good purpose.
