We can now move into territory that's a little more in line with everyday reality — ways of opening to psi [psychic abilities/phenomena] that we all can relate to and that offer us some practical direction. The most obvious category is the regular practice of certain right-brain activities, such as meditation, yoga, chi kung, self-hypnosis, various martial arts, breathwork, focused performing arts and athletic activity, biofeedback, prayer, and guided imagery. All these activities accelerate the development of psi ability.
