Bahman Yasht

In the Vohûman Yasht commentary (zand) it is declared that Zaratusht asked for immortality from Aûharmazd a second time, and spoke thus: 'I am Zaratusht, more righteous and more efficient among these thy creatures, O creator! when thou shalt make me immortal, as the tree opposed to harm, and Gopatshah, Gosht-i Fryan, and Kitrok-miyan son of Vishtâsp, who is Peshyotanu, were made. 2. When thou shalt make me immortal they in thy good religion will believe that the upholder of religion, who receives from Aûharmazd his pure and good religion of the Mazdayasnians, will become immortal; then those men will believe in thy good religion.'
