Many of them seem intent on getting Jung to abandon his conventional belief in any real dichotomy between good and evil, and to recognize that God and the devil are just two sides of a single reality; none of them, however, has any great gift for getting to the point.
That has been my impression of occult spirit-guides and prophets in general, and one of the reasons that I was able to drop the last vestiges of occult leanings in 1975 when I became a converted, or at least reviviscent, Christian.
