Hypnosis and Hypnotism

There is a difference between hypnosis and hypnotism. Hypnosis is a state of a person. It is an artificially induced state of relaxation and concentration in which deeper parts of the mind become more accessible: used clinically to reduce reaction to pain, to encourage free association, etc. And hypnotism it is the process of inducing hypnosis. So, don't confuse those two terms in order to realize what each of those terms means.
There are several types of hypnosis and each of those types is distinguished by the nature of hypnotism and aims people have when they produce hypnosis in somebody. There are hypnotizers who state that they use hypnotism in order to heal people from some psychological diseases. And there are also people who confirm that they were healed from some addiction or something like that by means of hypnosis. But, there are also people who state that it is impossible to help one by means of such suggestion.
One way or another the nature of hypnosis is a suggestion of certain thoughts to a person who is in state of hypnosis. So, from the psychological point of view it is possible to change something in a person's character by means of suggesting certain beliefs or by means of blocking certain unwilling desires. There are some people who are known all around the world as rather skillful hypnotizers and they are recognized as people who are able to heal by means of hypnosis.
Though, in most cases there always those, who are able to explain such "treatment" as simple quackery and they have a number of arguments to weight their thought. But for some reasons, there always were and, likelihood always will be those who proclaim their selves as hypnotizers and those who believe in their supernatural ability.
One may reject the fact of hypnosis but it will change nothing. So, instead of neglecting it there is a point in learning more about hypnosis and hypnotism in order not to be tricked by another "healer" and in order to know about use one may gain from hypnosis. Our psychic is something that percept the suggestions and restrictions we suggest to it, so, maybe there is a point to suggest to our psychic thing that will make our life easier.
