The word "Airyaman" has its origins in ancient Zoroastrianism and comes from Avestan, the ancient eastern Iranian language. In Zoroastrianism, "Airyaman" is one of the Amesha Spentas, meaning an immortal divine being or one of the six beneficent and protective spirits of Ahura Mazda, the supreme deity.
The term "Airyaman" is derived from the Avestan word "airya", meaning "noble" or "Aryan", and "manah", which translates to "mind" or "spirit". Therefore, "Airyaman" can be understood as the embodiment of the noble mind or spirit.
It is important to note that the term "Airyaman" is specific to Zoroastrian cosmology and theology and may not have a direct equivalent in other belief systems or languages.
