The book introduces the reader to one of the most popular areas of psychotherapy in our time - rational emotional therapy (RET) Its founder, Albert Ellis, believes that all people tend to build illogical, irrational mental combinations, which are called "mystical thinking" within the framework of the RET. Ellis argues that virtually all human problems are the result of mystical thinking, subjection to numerous “should”, “should” and “should”. Of course, a person has to face real problems, but the horror and exorbitant severity of the accompanying experiences are fictional, illusory demons. RET states that a person can control and influence their emotional reactions, feelings, and behavior.[D] Since he involuntarily causes himself to suffer, he can also cause himself to cease to experience suffering. RET teaches people not to depend on circumstances and not to succumb to suggestion, to think independently, without looking at what most people think and feel. For anyone who is in any way related to therapeutic work: students, medical and social workers, practicing psychotherapists .
