Edward C. Peach, who published under the pen name, "Ophiel," wrote eight books during the 1960 - 70's on occult topics: astral projection, creative visualization, caballa magic, clairvoyance, contacting the demiurge, general occult, talismanic magic, and a system of divination he called the Oracle of Fortuna. Also, Ophiel wrote a series of private lessons and short vignettes which he sold separately.
