Ahhhh, you will have to find and read at least a few books. NLP is a mental method that works best one on one and with a well trained person "doing". Yeah, if the goal is some specific mental change.
However, the human mind works in modes like visual, auditory (more tonalities than conceptual "parsed" meaning), kinesthetic. And sub modes like within visual there is image brightness. Note: this works with the so common among NTs non logical non verbal thinking.
A person can match up modes (hint: if a person talks to you with visual mode words, do not speak back to him in kinesthetic, I.e. "Can you see what I mean?". "Yes, I think I have a feel for it."
Obviously best one on one. However, certain internal processing sub modalities tend to be mostly (statistically) successful. Like: if you, as an advertiser, want to make a mental impression not easily lost, then when the item being advertised appears on screen you can: 1. brighten the image, 2. make the image of the item larger, 3. make the image of the item sharper, 4. with a mixed mode synesthesia - make the sound track louder. . .
And you get in past most folk's defenses and to the most vital subconscious part of the brain.
Much more to it, but NLP methods are in ads and political speaches and news broadcasts. . .
Visual images make a their point without words. When the political ad plays that slow plaintive piano with all the minor chords most people feel sad and would feel sad even if the downtrodden group for which sympathy is being drummed up is child molesters.
It gets past logic, and the conscious mind, and right to the heart of a person. Was developed to be used thereputically. But is used in ads, speaches, stage magic, even crooks (well, legal crooks that is: if not crooks what are advertisers and speechwriters?) use it.
I see and hear it all around since being sensitized.
