In any event, the three apparent conditions required for voluntarily inducing an out-of-body state in most individuals seems to be: (1) achievement of a state of profound quiet in the body such that the bifurcation echo fades and resonance at approximately 7 Hertz is established, (2) synchronization of the two brain hemisphere wave patterns, and (3) subsequent stimulation of the right hemisphere of the mind to attain a state of heightened alertness (which, of course, interferes with brain hemisphere synchronization but not until a sufficient level of enhanced frequency range has first been established to help achieve the out-of-body state).
