Initiation into the rites of Mithras, like initiation into many other ancient schools of philosophy, apparently consisted of three important degrees. Preparation for these degrees consisted of self-purification, the building up of the intellectual powers, and the control of the animal nature. In the first degree the candidate was given a crown upon the point of a sword and instructed in the mysteries of Mithras’ hidden power. Probably he was taught that the golden crown represented his own spiritual nature, which must be objectified and unfolded before he could truly glorify Mithras; for Mithras was his own soul, standing as mediator between Ormuzd, his spirit and Ahriman, his animal nature. In the second degree he was given the armor of intelligence and purity and sent into the darkness of subterranean pits to fight the beasts of lust, passion and degeneracy. In the third degree he was given a cape, upon which were drawn or woven the signs of the zodiac and other astronomical symbols. After his initiations were over he was hailed as one who had risen from the dead, was instructed in the secret teachings of the Persian mystics, and became a full-fledged member of the order.
