Gushtásp had by his wife Kitabún, the daughter of the king of Rúm, two sons named Isfendiyár and Bashútan, who were remarkable for their piety and devotion to the Almighty. Being the great king, all the minor sovereigns paid him tribute, excepting Arjásp, the ruler of Chín and Má-chín, whose army consisted of Díws, and Peris, and men; for considering him of superior importance, he sent him yearly the usual tributary present. In those days lived Zerdusht, the Guber, who was highly accomplished in the knowledge of divine things; and having waited upon Gushtásp, the king became greatly pleased with his learning and piety, and took him into his confidence. The philosopher explained to him the doctrines of the fire-worshippers, and by his art he reared a tree before the house of Gushtásp, beautiful in its foliage and branches, and whoever ate of the leaves of that tree became learned and accomplished in the mysteries of the future world, and those who ate of the fruit thereof became perfect in wisdom and holiness. In consequence of the illness of Lohurásp, who was nearly at the point of death, Zerdusht went to Balkh for the purpose of administering relief to him, and he happily succeeded in restoring him to health. On his return he was received with additional favor by Gushtásp, who immediately afterwards became his disciple. Zerdusht then told him that he was the prophet of God, and promised to show him miracles. He said he had been to heaven and to hell. He could send anyone, by prayer, to heaven; and whomsoever he was angry with he could send to hell. He had seen the seven mansions of the celestial regions, and the thrones of sapphires, and all the secrets of heaven were made known to him by his attendant angel. He said that the sacred book, called Zendavesta, descended from above expressly for him, and that if Gushtásp followed the precepts in that blessed volume, he would attain celestial felicity. Gushtásp readily became a convert to his principles, forsaking the pure adoration of God for the religion of the fire-worshippers.
