Our subconscious, the Universal Power, accepts whatever it is that we think or say. Our subconscious or Universal Power does not judge or criticize us but rather, only accepts our thoughts and words as true. Once accepted it then reflects our beliefs in our lives as experiences. If I want and choose to believe that "I am not good enough" I will experience that self image in my life.
However, if I am willing to work at releasing that self limiting belief and to start affirming that "I am perfect, whole and complete," holding on to that new affirmation, repeating it often, then it will eventually become what I believe to be so, to be my truth. This new belief about who I am will then begin to source and create new experiences that are in alignment with my new truth.
