Ashavan (Avestan: 𐬀𐬴𐬀𐬬𐬀𐬥 ašavan) is a Zoroastrian theological term. It literally means "possessing/mastering aša" and has been interpreted as "possessing/mastering truth" or "possessing/mastering righteousness", but has further implications: The linguistic cognate of Avestan ašavan is Vedic ऋतावन् ṛtā́van, which, however, has some functional differences vis-à-vis the Zoroastrian term: That the souls of the dead dwell in the radiant quarters of Asha (Yasna 16.7) has a Vedic parallel in which the seat of truth is located in the other world.
