Swift couriers rode continuously from the marches of Ctesiphon to bring grave tidings to King Anushirvan: his son Nush-Zad had raised the banner of rebellion, rallying freed prisoners, outlaws, and foreign partisans to his cause. The news cast a dark shadow over the monarch's heart. He who had bound the world in justice now faced defiance from within his own bloodline.
Anushirvan summoned his chief Mobad for a secret counsel to deliberate upon this sorrowful turn of fate. Thereafter, he commanded his royal scribe to draft a formal decree—a letter heavy with grief, righteous anger, and immortal wisdom. The letter opened with profound praise for Yazdan, the Eternal Creator of the cosmos, the moon, and Saturn, whose divine law governs all things from the smallest ant to the roaring elephant, and from dry straw to the mighty Nile.
Addressing the rebellious prince, the King reproved Nush-Zad for allowing his wisdom to be overshadowed by demonic temptation. He reminded his son of the absolute inevitability of death, noting that the earth's bosom is filled with fallen monarchs and forgotten warriors, and that neither the fragile mosquito nor the colossal rhinoceros can escape fate's talons. Anushirvan declared that if destiny had decreed the end of his own reign, Nush-Zad would have naturally inherited the throne; thus, this rash betrayal was pure madness. He emphasized that he feared not the loss of wealth or kingdom, but only the anger of Yazdan should he prove ungrateful for the Royal Glory bestowed upon him. Finally, touching upon the treasonous correspondence between Nush-Zad and the Roman Caesar, Anushirvan restrained his tongue from directly cursing his son, recognizing that cursing his own flesh and blood would be cursing himself.
