Learning plays an important part in perception. The Programmers try to get their victims to subscribe to philosophies and ideas that will make it hard for them to rebel against their controllers. This is what is termed indoctrination. The same methods of teaching that others find useful are employed. Ways of thinking are incorporated by the slave via handlers, programmers, and the cult they belong to.
Everyone tries in their own way to make sense of life. This is a natural brain function, so that the human mind can understand how to deal with the future. The mind takes raw data, and then applies some type of logic, and comes to conclusions. Once accepted these conclusions can be as hard as nails, and they will defy any attempt to change them, even in the light of new evidence. If the Programmer is smart enough, he can get an alter to logically believe anything. Once the belief is embedded, it will remain there tenaciously.
In the Illuminati, "great" masters and adepts teach "hidden mysteries". The slave feels the authority that emanates from this teacher with special gifts and abilities. The slave is hardly in a position to question the teachings being given from on high. Circular reasoning, lies, and other tricks are used to convince the person that the occult world is true. For instance, "God abandoned you, therefore you need to cling to us, the only ones who would see any use in you." (The truth is that the cult staged a crisis where their actor playing God abandoned the child to the cult’s abusiveness. The whole event was simply cult abuse--with God taking the blame.)
