One fact that I am certain of about hypnosis – It reveals to us that we have a mind that is very powerful. Its potential is unlimited.
If we based on studies about our conscious mind, it may still bring us some amazing results. But in comparison with our subconscious, it pales in comparison.
The power of our subconscious mind brought on through hypnosis gives us a glimpse of what our mind is capable of. For example, if we were to immerse our hand in cold icy water, we would withdraw our hand after a few second. But under hypnosis, this is not the case. The person is able to withstand the coldness under the suggestions by the hypnotist.
The key is you must know the technique of hypnosis (and be trained well first!)
