This handbook of mystical symbolism was written by Karl Weinfurter as a guide for the practicing student of mysticism. Based on rich personal experience, he describes and explains the symbols that the practicing mystic receives as visions, in dreams, or as somatic signs, as the language of the Holy Spirit for marking and confirming a correctly chosen path. This gives every practical mystic the opportunity for self-assessment of their journey and the interpretation of the phenomena that arise. The mystical primer is the first useful key to interpreting extrasensory visual messages. A classic of modern mysticism, it is the standard work for seekers of spirituality in a new, gentle revision.
