What was here before you was very great. It uncovered the secret to which you are blind, the secret of communion with the dead. It began to be able to use intelligent energy in its technology. To use souls as tools. Look at the carvings at Dendera in Egypt. Those strange objects in the containers are not electrical filaments or religious symbols. Those are souls. The walls of the containers bear a electrical charge of a type that imprisons them. Because of the use of such technology, elemental bodies extended their perception outside of the time stream, with the result that the school of the earth ceased to work as a place of change. Who knows the truth, cannot find their weakness, and that is your aim on earth. What was worse the knowledge of this power was kept from the common, ordinary people who have little self-will to begin with, and so are the only ones really capable of making good use of such abilities. The old world was destroyed because of its own greed and secretiveness. Those least evolved rose to the top, as happens here. Your leaders as you call them, are all people with damaged senses of self-worth The damaged goods run the civilization. That's why it cannot last.
