Original text - Engels - Hypnosis

Hypnosis is a mental state (state theory) or set of attitudes (nonstate theory) usually induced by a procedure known as a hypnotic induction, which is commonly composed of a series of preliminary instructions and suggestions. Hypnotic suggestions may be delivered by a hypnotist in the presence of the subject ("hetero-suggestion"), or may be self-administered ("self-suggestion" or "autosuggestion"). The use of hypnotism for therapeutic purposes is referred to as "hypnotherapy".
