Quotes:Airyana‐ishejo
Blavatsky, Helena Petrovna
Airyana‐ishejo. The name of a prayer to the “holy Airyamen”, the divine aspect of Ahriman before the latter became a dark opposing power, a Satan. For Ahriman is of the same essence with Ahura Mazda, just as Typhon‐ Seth is of the same essence with Osiris (q.v.).
