The process of entry into a secret society, an occult group, or a mystical stage of religion. The idea of initiation was inherited by the Egyptians and Assyrians from Neolithic peoples who possessed secret organizations or "mysteries" analogous to those of the Medwiwin of the North American Indians or those of the Australian Blackfellows. Initiation was a stage in the various grades of the Egyptian priesthood and the mysteries of Eleusis and Bacchus. These processes probably consisted of tests of courage and fidelity (as with the ordeals of primitive peoples) and included such acts as sustaining a severe beating, drinking blood, real and imaginary; and so forth.
In the Popol Vuh, the saga of the Kiche Indians of Guatemala, there is a description of the initiation tests of two hero-gods on entrance to the native equivalent of Hades. Indeed, many of the religious mysteries typified the descent of man into hell and his return to earth, based on the corn mother legend of the resurrection of the wheat plant.
Initiation into the higher branches of mysticism, magic, and Theosophy is largely symbolic and is to be taken as implying a preparation for the higher life and the regeneration of the soul. Typical of such rites are the ceremonies for initiation and advancement of Freemasons.
The great religions instituted initiation rituals, such as the baptism and laying on of hands in Christianity, and the circumcision and bar mitzvah in Judaism.
The ordeal rituals of initiation into Freemasonry echo older ceremonies symbolizing the mysteries of birth, pain, death, and the life of the soul. Many trades also have traditional ordeal ceremonies for the initiation of young apprentices, similar to those instituted by college fraternities.
In esoteric traditions, both Eastern and Western, initiation refers to the entrance into various levels of purification of the individual through development at all levels of experience— body, mind, emotions, and soul—as discussed in various forms of magical and mystical traditions. Initiation can be used in a somewhat watered-down sense, and is adaptable to any new insight brought about by the ups and downs of living. However, it more properly is used to refer to those insights created by a planned system of inner development while the individual is involved in mastering a particular system of esoteric teachings.
