The planet Pluto the seventh planet from the earth and is associated with the afterlife realm referred to as the realm of consciousness. This afterlife realm is the realm for the final development of full consciousness. The planet Pluto was discussed by Cayce years before it was actually discovered! He referred to it as Vulcan and also as Septimus. When Pluto was discovered, Cayce affirmed that Vulcan or Septimus was the same planet as Pluto. The Pluto realm of the afterlife brings regeneration and a growth in consciousness, but also can bring self-centeredness. Pluto represents spiritual growth and development of the soul and its influence is just now developing in the destiny of humanity. 

After all the afterlife realms associated with our solar system have been fully experienced and all the lessons have been fully learned and the proper level of soul growth has been attained, the soul can move on to other afterlife realms and even other solar systems where other souls are going through the same thing.
