I know a while ago it was discussed whether listening to the Paraliminals via a light-sound machine (Nova, Proteus, Zen Master, etc) will enhance the effect of the CD on a person's brain. Maybe since then this technology has improved. Should this machine only be used for track 3 of each CD or for all the tracks? It is my understanding that track 3, which is also recommended during sleep, is the one that gives the stimulation to the brain through the different sound in each ear.
