There are two known ways of getting into this altered state, which some describe as the "Zone". 1) self-hypnosis - affecting the subconscious 2) Alpha state (where alpha brainwaves are dominant), it is called crystal countdown (from Laurie Cabot's book) in which you meditate to get into the "alpha state". I do not think these two a mutually exclusive, but many people swear by number 2. What do you use? What is your preference?
