Mental or internal representations are the patterns we use to represent the world to ourselves in our own minds and consist of our internal pictures, sounds, dialogues, and feelings. By beginning to take control of your internal representations, you can start to manage your state in exactly the way that you want to achieve your desired outcome. A simple example is when you remember a happy time. As you remember that time now, pictures, sounds, and feelings from that time will return to you as you relive that time. Your mind makes no distinction between the original happy time and your memory of it, so if you re-enter that memory fully and completely, you will naturally re-enter the happy state that you experienced at that time.
