- CCH is a very sloppy title, for Procedure CCH is really C for control, D for duplication, C for communication, Ct for control of thought=havingness; and that is the real name of it. First, we get the person under control, get him into the capability of duplicating and then we move him up into communication more or less on a person level. Now we take the mind. The mind consists of mental image pictures and if duplication is addressed to the mind we get communication. The third zone is the control of the thetan, which brings us to the control of thinkingness, Ct. (PAB 122)
