The old mystical ‘doctrine of correspondences’ declares that ‘as things are above, so they will be below’. In other words, conditions in the exterior world affect our inner moods; while conversely our inner state of being also affects the way our outer surroundings are ordered. When stripped down to its basic premises, this is a natural law that people would do well to be mindful of. On a personal level, it implies a profound connection between thought and speech, between a person’s intentions and actions, and between their personality and lifestyle. It is not only theologians and philosophers who have grasped this truth; the same thinking underlies many schools of psychology including neuro-linguistic programming (NLP), whereby patients are taught to remodel the way they think in order to change their perception of events in their lives.
