Almost all the self-help books which pertain to ‘success mechanisms’ have to deal with the mind. And whenever any mental exercise relates to ‘thought conditioning’ in some form or the other, it always takes me back to Hypnosis. As a certified hypnotherapist (and do not confuse this with the fake stage hypnosis shows for entertainment), I can only say that the techniques one familiarizes oneself with whilst pursuing the extensive course (visualization, dramatization, affirmation, anchors, etc.) are often seen taking on different nomenclatures and being presented to the people. Some books such as ‘The Secret’ sell hundreds of millions of copies, but it is unclear how many actually benefited.
