You accomplish this with your mental energy and effort, which causes the Law of Manifestation to begin working successfully. To do so, you must have investigated your shadow to see what could be impeding your capacity to believe in your potential to attain your goal. Only then can you work to overcome these limitations through self-development or therapy. Overcoming your shadow is important because it allows more of yourself to show up for the world. More of yourself means more ability to believe in your potential to achieve your goals. This increased ability then starts the cycle again: more you believe, more you can believe, and so on. Using the example above: if you don't deal with your jealousy and hatred toward your brother, they will continue to cloud your judgment and limit your belief in yourself. By investigating these feelings and then working to overcome them, you free yourself up to believe in yourself enough to let go of your goal and move on with your life.
