So, since hypnosis merely creates an altered state of mind, and since hypnosis revolves around the power of suggestion, persuasion can be practiced in many different ways as a tool to change people's behavior. For these reasons, hypnosis is used both in the art of persuasion and in therapy.
Covert hypnosis is the type of hypnosis that is utilized in the art of persuasion. Like any other kind of persuasion, covert hypnosis uses the art of suggestion to give you consistent results. However, because this form of hypnosis is covert, the suggestions that you'll be planting in people's minds will be much more indirect than the suggestions that are installed in people's minds through therapeutic hypnosis.
Covert hypnosis also utilizes all types of suggestion. This means covert hypnosis uses the power of non verbal suggestion even more than it uses the power of verbal suggestion. There can be nothing as under the radar and covert as suggesting something to somebody without having to even say a word to them.
The verbal forms of suggestion that covert hypnosis uses are also difficult to detect. So, instead of saying something to someone directly, you will be saying it to them indirectly to the point where it will not be evident to the person whom you are talking to that you are actually suggesting to them that they do something that you want them to do. This is why covert hypnosis is perfect to integrate into the art of persuasion, because you can modify people's emotions and decision making processes without them being conscious of it. This means it is not likely anybody will try to resist you because they will not have any idea that that there are any suggestions for them to resist.
Another powerful hypnosis tactic that can be used is to use covert persuasion to take control of various social structures that exist in any social environment that you may be in. The more power you have over a class system or group, the more it will appear to others that you are a likable person and authority figure. When you appear to other people as an authority figure, your social value increases to the point where people become far more suggestible so that you can get what you would like from them.
