6925. The spirits of the earth Mercury do not stay in one place, or within the sphere of the spirits of one world, but wander through the universe. The reason of this is that they relate in the Grand Man to the memory of real things, which memory must be continually enriched. Hence it is given them to wander about, and everywhere to acquire for themselves knowledges. If while thus journeying they meet with spirits who love material, that is, bodily and earthly things, they shun them, and betake themselves where they do not hear such things. From this it can be seen that their mind is uplifted above sensuous things, and thus that they are in interior light. This it was also given actually to perceive when they were near me, and were speaking with me. I then observed that I was withdrawn from sensuous things, insomuch that the light of my eyes began to grow dull and obscure.
