Your beliefs condition and qualify the space that surrounds you, creating an electromagnetic imprint that ultimately serves to attract all of your life experiences. Thoughts are real in that they have a life of their own once you create them. Most of the time, however, you are clueless on how you set your version of the world into motion. Beliefs are agreements about reality, and agreements can be changed. It is essential to understand that beliefs are the thoughts you hold within your imagination-consciously, subconsciously, and unconsciously-and in the imagination all things are real. All thoughts produce energetic vibrations, and even though you cannot see frequencies, the airwaves are full of who you are.
