No one can take advantage of you without your permission. Nothing can bother you unless you let it. If another person does not physically touch your body, space or property, then this other person, cannot effect you. Nobody can control you, but yourself. Nobody can hypnotize you.
Hypnosis is nothing but auto-suggestion.
You can only be hypnotized if you believe that the words the hypnotist utters to you, are true and should be applied to you. Self control is the great law of mental health. Be not quick to anger. Learn to control your emotions. Don't react, only act.
