12. Errors in Spiritual Investigation
Everything that the human being experiences on entering the spiritual world is designated ordinarily as the experience with the Guardian of the Threshold. I tried to describe something concrete about this experience in my Mystery Drama, The Guardian of the Threshold. Here it only need be mentioned that at a certain stage of spiritual development, man learns to know his inner being as it can love itself with the force of an event of nature, as it can be frightened and horrified on entering the spiritual world. This experience of our own self, of the intensified self of that inner being that otherwise never would come before our soul, is the soul-shaking event called the Meeting with the Guardian of the Threshold. Only by having this meeting will one acquire the faculty to differentiate truth from error in the spiritual world.
