Zartosht No-Diso, observed on May 22, 2026 according to the Shenshai calendar, marks the death anniversary of the prophet Asho Zarathustra at the age of 77. The day holds significant spiritual importance in the Zoroastrian tradition as it commemorates the departure of the prophet who founded the religion and fulfilled a divine mission to dispel evil from the world.

Common narratives often depict Zarathustra’s death as resulting from a mortal attack by a Turk at his sacred Atash Behram fire temple, where he was said to have been stabbed from behind. According to this account, Zarathustra retaliated by casting his rosary at the assailant, leading to both their deaths. However, an alternate and more nuanced understanding is derived from traditional scriptures, which portray Zarathustra not as an ordinary human but as Ahura Mazda’s "chosen one," endowed with supernatural powers and divine authority.

The scriptures state that for over four millennia before Zarathustra’s birth, a malevolent force named Tur-Bara-Tur—described as a dark, satanic entity—caused immense suffering on earth. Geush Urva, a divine guardian of souls, petitioned Ahura Mazda to intervene. In response, Ahura Mazda is said to have sent Zarathustra to reveal the path of Asha (truth and purity) and to ultimately defeat Tur-Bara-Tur’s reign of evil.

After establishing the Zoroastrian faith, Zarathustra fulfilled his second mission by using his innate power—the "Aoj"—to shatter Tur-Bara-Tur’s monstrous form with a ring of shining halo during a final sermon at the consecrated fire temple. The resulting cosmic shock wave threatened the very stability of the earth, but to prevent destruction, Zarathustra absorbed the impact himself. His earthly body disintegrated, returning to the subtle elements of the spiritual realm, while his sinless soul ascended to Pahlum Ahwaan (Paradise).

Renowned scholars have suggested that Zarathustra’s demise was extraordinary, possibly caused by a divine fire or lightning rather than a human attacker. Clarifying key terms, the concept of "Aoj" refers to a divine power granted by Ahura Mazda to celestial beings as well as to Zarathustra, elevating him to a status equal to the Yazads (holy beings). This power rendered Zarathustra impervious to ordinary harm, including attempts on his life by demons or mortals.

The traditional account of his death by dagger is thus understood symbolically or as a misinterpretation. Zarathustra’s actual passing resulted from his conscious choice to absorb the destructive energy unleashed in the defeat of evil. The belief that a mortal Turk killed him contradicts scripture, which assures that no evil force could strike Zarathustra.

This perspective invites followers to honor Asho Zarathustra with reverence appropriate to his exalted spiritual stature, moving beyond simplistic or literal interpretations. The day serves as a reminder of his profound legacy and the enduring values of truth and righteousness in the Zoroastrian faith.
