Introduction
Spenta Armaiti, "Holy Devotion" or "Bounteous Devotion" (later Spandarmad), is one of the six Amesha Spentas, and the one most closely identified with a specific part of creation: the earth. She represents devotion, humility and the right, loving attitude that Zoroastrians should hold toward Ahura Mazda's creation.
The Amesha Spentas ("Bounteous Immortals") are six (or, counting Ahura Mazda himself as their head, seven) divine beings who represent and administer aspects of Ahura Mazda's good creation. Zoroastrian theology generally treats them as emanations or aspects of Ahura Mazda's own nature rather than as separate offspring in an ordinary genealogical sense, and each is opposed by one of the six chief daevas in Zoroastrian dualism.
The earth and devotion
As the Amesha Spenta most closely associated with the earth, Spenta Armaiti represents the properly humble, caring and devoted relationship that humans should have with the created world, particularly the land they cultivate, connecting agricultural piety directly to religious devotion.
Feminine principle
Spenta Armaiti is one of the female Amesha Spentas (along with Haurvatat and Ameretat), and her association with devoted, nurturing care has led scholars to see in her a continuation of very old Indo-Iranian earth-goddess concepts, given a more abstract, ethically oriented form within Zoroastrian monotheism.
Opposing daeva
Spenta Armaiti is opposed by Nanghaithya, one of the six chief daevas, whose name is cognate with the Vedic twin gods the Nasatyas (the Ashvins) of Hindu tradition, another example, alongside Indra, of a figure from the shared older Indo-Iranian religion recast as a demon in the developed Zoroastrian system.
