If you understand that hypnosis is closely linked to the subconcious mind, you will accept the fact that hypnosis is not a subject that can be easily explained, measured and proven.
The subconscious mind is so vast that till today, it is hard to prove who is saying the right thing, in particular statistics about human mind’s potential. Some sources say we use 5% of our brainpower while others indicate a 10%. This area alone is subject to debate, all because we do not really understand the subconscious mind, its working and potential.
Therefore hypnosis will always be a baffling subject to the human’s mind.
