The American Psychological Association published an article that discusses how hypnosis is different from both mindfulness and meditation. It quotes a psychology professor from the Icahn School of Medicine at Mount Sinai as saying, “Whereas meditation helps you accept a problem, hypnosis allows people to make changes to do something about the problem.”
The article goes in-depth on other aspects of hypnosis, too, such as the use of hypnosis to treat specific conditions. It is well worth the read. You may find it here.
