COMMUNICATION BRIDGE
  1. it simply closes off the process you were running, maintains ARC, and opens up the new process on which you are about to embark. (PAB 151)
  2. before a question is asked, the preclear should have the question discussed with him and the wording agreed upon as though he were making a contract with the auditor. This is the first part of a communication bridge. It precedes all questions but when one is changing from one process to another the bridge becomes a bridge indeed. (PAB 88)
  3. the reason we use a communication bridge is so a pc will not be startled by change, for if we change too rapidly in a session, we stick the preclear in the session every time. We give him some warning; and that is what a communication bridge is for. (PAB 151)
