'Aṣ̌a' derives from the same Proto-Indo-European root as 'Airyaman', the divinity of healing who is closely associated with Asha Vahishta. At the last judgement, the common noun "airyaman" is an epithet of the "saoshyans", the saviours that bring about the final renovation of the world. The standing epithet of these saviour figures is '"astvat"ә"r"ә"ta"', which likewise has "arta" as an element of the name. These saviours are those who follow Ahura Mazda's teaching "with acts inspired by aṣ̌a" ("Yasna" 48.12). Both Airyaman and Asha Vahishta (as also Atar) are closely associated with Sraosha "of Conscience" and guardian of the Chinvat bridge across which souls must pass.
