But every person practicing hypnotism worth his work is the first to admit that the effect is only temporary. For example, a person can be made to quit smoking by suggesting through hypnosis that the smoke is poisonous and deadly. That person then starts to become adverse to smoke, and feel nauseous whenever he gets near it. Thus, he may shun cigarettes. But if this is not followed up by corresponding therapy and other methods geared for long-term results, the habit will come back eventually.
Another proven limitation of hypnotism is even while under it, a persons common sense, principles, beliefs and life convictions remain unchanged throughout and after the experience. No one can also be hypnotized against his will, because the mind has to be willingly and consciously open to be affected by the hypnotists suggestions.
For example, hypnotism cannot make a Muslim eat pork or a Superman fan fly out of a window. Since the mind is still fully alert only this time the subconscious is more open the persons sense of safety is still on guard. His sensibilities will continue to govern his decision-making process.
Then again, we can never really be sure. One story goes saying a man, undergoing hypnosis to boost his self-confidence, was told by the hypnotist that he could do anything, anything as long as he puts his mind into it. For more effect, the hypnotist says: Why, you could even rob a bank if you want to. Although the hypnotist may have meant the statement only as a metaphor, his subject then proceeds to rob a bank a couple of days later!
