When you purchase this package it will take you to a page where you can download 5 different "Binaural" Audio samples that help induce an altered mental state that is conductive to Astral Projection.
Binaural audio is a technique that sends a different audio frequency into each ear so that the resulting "beats" from the audio interference inside your brain creates a pattern that your brain waves settle into. These particular audio samples are tuned to create the same types of brain waves as people who are projecting create. Binaural Audio has been called "Speed Meditation" because it is an extremely fast way of training the brain to create wave patterns that normally take many years of intense meditation practice to develop.
This program is weak on documentation but is extremely easy to use and fairly effective. Just play the sounds from a stereo audio source (preferably a good pair of noise canceling head phones) and you will feel *something* almost immediately. For me it was almost like a cold chill racing through my body and then shortly after I found myself approaching the familiar drowsy, relaxed state that proceeds an astral projection... but a lot faster than usual.
Like most Astral Projection techniques, the real trick at that point is to maintain consciousness while you allow your body to get more relaxed and finally "slip out" instead of just drifting off to sleep.
While this program can help get you to the door of Astral Projection pretty quickly, as with any psychic development program, they can't do it all for you. You still have to cross the threshold yourself and that takes practice.
On the whole, I think this program is a good value for the price.
