In a quiet and reverent mood, the reader transmits to the loved one the contents of the book which describes the realms the person will be traversing from death to another birth. These spiritual spheres that the person is traveling through need a road map to help understand the new atmosphere and the topology of the spiritual world.
These spheres are the interpenetrating realms of hierarchical beings who inhabit these “heavens” that are so beautifully described in the cosmology of Spiritual Science. They are often referred to as the realms of the “harmony of the spheres.”
Reading descriptions of these realms to the deceased helps them orient themselves in these spheres which they have been “born” into recently.
