If you want to learn NLP (neurolinguistic programming) then there are a few things you should be aware of.

NLP is a field that has been refined over the many years, since its original founding by Richard Bandler and John Grinder. Since this time the field has been adopted by many hypnosis schools as a means of teaching people how to make changes to themselves and others that have a positive impact on every aspect of life. 

These changes result most commonly by identifying what a person deems to be an issue of some form, and then reframing these issues. NLP however is not a field that is reserved for purely therapeutic purposes. NLP also incorporates what's known as the Milton Model.  

If you want to learn NLP so that you can apply it to covert hypnosis, then you will need to learn the Milton Model. The Milton Model is about applying NLP discreetly in conversational settings in order to make changes in a person to your benefit.  This is achieved by first establishing rapport with a person and having them really enjoy your presence and company.

Once this form of rapport is established, the process of applying NLP becomes much easier.  Changes in a person can be made by planting anchors. Anchors are a way of associating certain emotional states or behaviours to certain actions. For example, let's say that a person was really happy and smiling since they were within your company.

When you learn NLP, you will learn that you can anchor this positive emotional state through an action of some form. This action can be as simple as tapping a pen on the table repeatedly, or even making a certain hand gesture.  

NLP does of course have many other uses as well, and if you want to learn NLP then you will also need to learn about submodalities and representational systems, and how the way in which a person analyses information can heavily determine their reaction to certain keywords or phrases.  

Another thing you will want to pay attention to when you learn NLP is the other person's body language. You want to mimic their breathing rate, body posture, positioning, hand gestures, facial expressions and all other forms of body language. This is a process known as matching and mirroring, and it will establish a subconscious form of rapport with the person you're speaking to.
