The higher forms of intelligent intercommunication between human beings are greatly helped by the indwelling Adjusters.  Knowledge and wisdom become cumulative because of man’s ability to communicate these possessions to succeeding generations. 
Broadcasters, one of superior seraphim, use an ideographic technique able to simultaneously transmit 144,000 messages.  The chief of Brilliant Evening Stars is ntrusted with custody, dispatch, of all personal messages.  Mind-energy manipulators are the experts of intercommunication between morontia and other types of intelligent beings.  The “harp of God,” a morontia contrivance, allow reception of perfected space communication.  A local universe is fully provided with adequate means of intercommunication, but personal messengers sometimes required.  Communication is one of the subjects of study in Melchizedek University. 
Communication methods in Paradise are utterly beyond the comprehension of human mind: one hour’s instruction on Paradise is the equivalent of ten thousand years of the word-memory methods of Urantia. 
Urantia is served by twelve technicians of interplanetary and interuniverse communication.  The lanes of energy for interplanetary communication are circuits between power centers or physical controllers. 
The physical controllers are occupied in the adjustment of basic energies undiscovered on Urantia, that are very essential to the interplanetary system of transport and to certain techniques of communication.
