Lecture VII

From what I have said you will see that a neighbouring stream must enter our culture—this is the “Mercury stream”; its presence is revealed through the fact that those who go through an occult development, such as has frequently been described by me, evolve towards the spiritual world, and by doing so experience many new facts. These facts stream towards them, they stream into their souls. We might compare the entrance of man into another world with the passing of a fish from the water into the air; the fish has first to be prepared for this by changing its air bladders into lungs. This resembles the transition from sense perception to spiritual perception, whereby a man's soul is made capable of employing certain forces in a different element. Many things are then revealed to him.
