It is. People using the Silva Method of mind control have been doing a form of Self Hypnosis for years. It is basically summed up with the statement "What the mind can conceive and beleive the mind can achieve."
The belief factor is one of the most difficult ones we need to deal with and the best place to deal with them is at the Alpha/Theta level. We are hypnotised to some degree or another every day of our lives. In fact all hypnosis is a form of self hypnosis. The best place to plant affirmations that is at the alpha theta level because at these levels our mind is dealing with subjective reality. An area of the mind where even the most fantastic ideas can be created and are accepted as possible by the mind because disbelief is suspended. It is these levels of the mind where the Fantastic Voyage like ideas become very real and very possible. (Just check some of your daydreams - those times you have gone into a trance and are functioning with a predominance of alpha or theta brainwave pattern. It is when these brainwave patterns are dominant that you are in a hypnotic state. For the mind to do something we must first believe it is possible. The best way to do that is check with the mind. If we want to change our beliefs about something we often need to experience the belief that something else is true.
The best time to program the mind is when it has a dominance of alpha/theta brainwave pattern. During this time we are focus within and on our thinking processes rather than expending the higher brainwave energy dealing with the outer world. The removal of distractions allows the mind to provide the answers to the body or conscious mind and we inform the mind that we want this information consciously. The information is always there we just haven't asked for itand developed our body mind connection. We ask the mind to perform a certain function and then we need to accept/trust the signals/answers that it gives us. Accuracy builds as the conscious mind becomes aware of the signals.
Self hypnosis coupled with the conscious belief that it is possible allows the mind to creatively expand what it is capable of. It will probably take a few self hypnosis session to overcome the limiting beliefs of the conscious mind before you see results.
