Hypnosis harnesses your greatest personal resource; your subconscious mind, to empower you to make the positive, permanent, life-altering changes you want to make for yourself.
After I have guided you into achieving a steady state of relaxation (for details see What IsHypnosis? page), your conscious mind drifts to the side and lets your subconscious take over, which by its nature is deeply receptive to accepting the suggestions that it receives throughout the session; some direct suggestions and others indirect.
Your subconscious mind can be compared in many ways to a four-year old child: Whatever you tell the subconscious, it believes is TRUE. It also can't easily distinguish between past, present, and future - everything is in the PRESENT to the subconscious. Therefore, the suggestions so readily accepted are also integrated as the present truth of your life.
