Rashnu

Rashnu (Avestan: 𐬭𐬀𐬴𐬢𐬏) is the Avestan form of Rashn, ultimately derived from a word meaning “just, straight.” In Zoroastrianism, Rashnu is a yazata (divine being) of justice, one of the three judges—along with Mithra and Sraosha—who pass judgment on the souls of the dead. His standard epithet is “the straightest,” reflecting his role as an arbiter of truth.

Role in Zoroastrian Cosmology

According to the Bundahishn, an 11th- or 12th-century Zoroastrian cosmological text, Rashnu is identified as an assistant of the Amesha Spenta Ameretat (Amurdad), who embodies “immortality.” In a subsequent passage, Rashnu is described as the essence of truth (arta/asha) that prevents the daevas (demonic beings) from destroying material creation. The text further states: “Rashnu adjudges even the souls of men and women as to bad deeds and good deeds. As one says, 'Rashnu shall not see thither the rank of the judge who delivers false judgment.'”

Etymology and Linguistic Forms

The Avestan name Rašnu (𐬭𐬀𐬱𐬥𐬎) is associated with the concept of straightness and truth. In Middle Persian, it appears as Rashn, while the modern Persian form is Rashn. The connection to justice and righteousness is central to its meaning.

Notable Bearers and Cultural Significance

As a theophoric name, Rashnu appears in ancient Zoroastrian contexts but is rarely used as a personal name in modern times. However, it remains culturally significant within Zoroastrian communities and among those interested in Persian mythology. The name embodies ideals of fairness and moral rectitude.
