Hypnosis is a valuable tool for self-empowerment and continuous personal growth, and can save you years of frustration and effort pitting your willpower against your stronger subconscious.
When youre in the hypnotic state, you are more open to suggestion. Imagine the possibilities! Whatever you can imagine and suggest for yourself, you can attain.
In a weight-loss session for instance, using visualization techniques and creating triggers while under hypnosis (which later you can reinforce with self-hypnosis), you can initiate physical changes in your body. You can create "the glove of anesthesia," to soothe pain. You can calm yourself down completely before a dentist appointment, so your body shows and feels no signs of stress. Hypnosis has been used in surgery in place of anesthesia, during childbirth, and with athletes to enhance their performance.
Still not sure how it can happen?
