A Suggestion is an idea that reaches the mind through the five physical senses, and/or the sixth sense, intuition.
In addition, all sensory input routes continually receive data from verbal, nonverbal, intraverbal and extraverbal communications as well as information about our environment such as thermal and pressure sensations and kinaesthetic awareness.
Suggestibility is a measurement of the intensity with which the brain and nervous system respond to incoming Ideas.
Suggestion plays an integral role in inducing hypnosis and is a vital instrument once hypnosis is induced. Suggestion is a major tool in successful persuasion of the subconscious mind.
