Secret Rituals of the Men in Black by Allen Greenfield

The Rituals have been found! For skeptics and believers alike, the secret rituals of occultism, and later, of trance mediumship, have always been something of a puzzle. The reason for all these profoundly bizarre goings-on became apparent only when we "cracked" the key secret cipher used in such rituals and spontaneous encounters. Once realized, a bizarre design, previously suspected by only a few diverse researchers working in widely differing fields, was fully exposed. It revealed an intricate worldwide pattern of communication between Ultraterrestrial Forces almost totally beyond our comprehension and human adepts, stretching from remote antiquity to the present moment. The entire literature of magical invocation and evocation, seen in this light, is revealed to be a disguised transmission of these technologies.
