Paul Foster Case was an American occultist of the early 20th century and author of numerous books on occult tarot and Qabalah. Perhaps his greatest contributions to the field of occultism were the lessons he wrote for associate members of Builders of the Adytum or B.O.T.A. The knowledge lectures given to initiated members of the chapters of the B.O.T.A. were equally profound, although the limited distribution has made them less well known.
