What You Listen to Over and Over Programs Your Subconscious and thus Your Life!
Equally important is making sure that when you go to sleep, there is no radio or tv program playing that can fill your mind with harmful or limiting ideas while you are not consciously awake to refuse them. If you must go to sleep with sound, choose powerful and uplifting words that will help you become the kind of you that you seek to be, or choose white noise or wordless music that allows your brain waves to enter into alpha, theta, and delta.
Even better, play a variety of solfeggio codes, for they will help strengthen you in many positive ways. Make your sleep a 'power sleep' by filling your room, body, and subconscious with thoughts and sounds that will produce the magnificent you that you were born to be. Night after night after night of the same information will cause it to become a truth for you.
