The LORD of the rings. Also, My Own Personal Justification Towards Trying To Learn To Love And The Appreciation Of Better Call Saul

 What is the study that proved that you can repeat the same phrase over and over (thus displaying the adequacy of use towards using a mantra of some kind ex. looking into a mirror in the morning and saying "I'm worth it!" in your own words every morning).

I was going to delete this question since I didn't want to give credit to someone (see do not judge by Jesus) who I viewed as an evil due to myself.  It is a scary world when things like brainwashing are mentioned and I didn't want to give credit to any initial person who completed this study.  Luckily, Google Gemini was adequate enough to provide a detailed response for me.

Google Gemini: 

While there isn't one specific, widely recognized study with the exact methodology you described ("repeating the same phrase over and over to a prisoner until they eventually believe it"), the phenomenon you're referring to is closely related to several well-established psychological effects, particularly the illusory truth effect.

Here's what the illusory truth effect suggests:

Repetition increases believability: People are more likely to believe statements they have heard repeatedly, even if those statements are false.

Familiarity breeds "truth": Repeated exposure makes a statement feel more familiar, and this feeling of familiarity is often misattributed to the statement being true.

Reduced cognitive processing: Familiar statements are easier for the brain to process. This ease of processing can also contribute to the feeling that the statement is more likely to be true.

Even with pre-existing knowledge: The illusory truth effect can occur even when people initially know the correct information. Repeated exposure to a falsehood can, over time, lead to them believing the falsehood.

While studies on the illusory truth effect often involve repeated exposure to statements, they don't typically focus specifically on prisoners in isolation. However, the principles of this effect could certainly be amplified in a prison setting due to factors like:

Limited information sources: Prisoners often have restricted access to diverse perspectives and information, making them more reliant on the information they are repeatedly exposed to within the institution.

Power dynamics: If the repeated phrases come from authority figures (guards, etc.), there might be an added element of perceived credibility or pressure to believe them.

Psychological stress and manipulation: Isolation, stress, and deliberate manipulation tactics can make individuals more susceptible to suggestion and belief change.

Historical Context and Related Concepts:

The idea of repeated messaging influencing belief is also connected to broader concepts like:

Brainwashing and thought reform: While controversial and complex, these concepts involve systematic efforts to change beliefs and attitudes, often utilizing repetition as one of many techniques.

Propaganda: Repetition is a key element in propaganda, where messages are repeated across various channels to influence public opinion.

Coercive persuasion: This involves using psychological tactics, including repetition, to influence a person's beliefs and behaviors against their will.

In summary, while there isn't a single study precisely matching your description, the illusory truth effect provides strong evidence for how repetition can increase belief in a statement, even a false one. This effect could be particularly potent in environments like prisons where individuals have limited access to information and may be under psychological stress.

I'm using this knowledge to learn to love the show that at first glance seems quite childish to me called Better Call Saul.  I would rather dwell where there is stability for awhile then dwell with the intense nature of actual courtroom shows for now.

I thought of the phrase independently "His (referring to God) gaze pierces flesh and bone."  This reminded me of the quote from The Lord Of The Rings that says "“His gaze pierces cloud, shadow, earth and flesh... a great eye, lidless, wreathed in flame.”
