usually you listen to the cd once, the binaural sound that brings the brain down to 7 or so hz in the theta/alpha range still lingers for atleast a half hour after listening to the cd so you can still attempt to do body awareness or even recall the body relaxing commands. Also the more times you listen to the cd the more vibrations in future sessions it will produce since the mind is getting more and more used to the commands and the binaural sound.
