Mystical doctrines have taken different forms with the consequence that some mystical writings may criticize or even contradict others. This situation is familiar enough in purely intellectual circles and to some extent in religious circles, but is less to be expected where direct communion and even union with the Supreme Truth and Reality are claimed.
