Hypnosis works by achieving a level of focused awareness, and at the same time bypassing the analytical aspect of the mind. Another way to describe the analytical aspect of the mind is that it is a comparing mechanism. When new information is introduced to the mind, the comparing mechanism compares the new information to what it already believes is either true or false. This is a protective aspect of our mind. This is why changing habits by willpower alone is so difficult – we often already believe we cannot change, so thinking about making the change happen (using willpower alone) is ineffective. Hypnosis is powerful because with focused awareness the analytical aspect of the mind is bypassed, and new, healthy and beneficial suggestions can be made directly into the subconscious, without the comparing mechanism rejecting these new beliefs. So the change we want to achieve in our life is accepted by the subconscious mind as true, and we see results quickly.
