We all have in our brains a thing called a Reticular Activating System (RAS), which is like a filter that lets in information that we need, and filters out information that we don’t. If we didn’t have this system, we would be bombarded with so much information that our senses would overload and we would go into massive overwhelm.
Instead, our brain registers what matters to us based on our goals, needs, interests, and desires.
When you say an affirmation over and over again, a couple of things happen. One is that it sends a very clear message to your RAS that this is important to you. When you do that, it gets busy noticing ways to help you achieve your goals. If ideal weight is your emphasis, you will suddenly begin to see every gym and weight loss product. If money is your goal, investment and earning opportunities will move to the forefront of your awareness. In essence, the affirmation can kick your creativity into high gear.
The other way affirmations work is that they create a dynamic tension in our beings. If what you are saying is at a higher vibration then what you perceive the truth to be, the dynamic tension is uncomfortable. For instance, if you are saying “I am joyfully and healthfully at my ideal weight” when in actuality you are 10, 20, 30+ kilograms above your ideal weight, a painful in-congruence is felt between what you perceive the truth to be and what you saying. Since this is uncomfortable, we want to rid ourselves of the tension. There are only two ways to do that: one is to stop saying the affirmation; the other is to raise the bar on reality by making the affirmation and reality match.
