Zend-Avesta

(Boyce 22) When the magician pays proper homage to the most frequently mentioned Amesha Spenta in the Zend-Avesta, Asha Vahishta, who "pervades the other creations, and through the sun, controls the seasons," he is endowed with the power of Ahura Mazda to create life--a divine attribute accessible to him via Asha Vahishta and his reverence and respect of fire (23).

Yasnas 44 & 45 of the Zend-Avesta hint that no soul would remember having been with Ahura Mazda previous to this life as a condition of coming to this world; therefore, the magician's knowledge of his own existence remains tenuous because his vision is clouded, just as he removed the knowledge of his two years tutelage from his son's memory.
