I can say as a binaural listener for about 5 years, with many kinds of audios tracks from 528Hz, 432Hz, healing, memory, brain, for healing, body repair, silva study method mind control, besides that, pranayama breathing, and much other stuff to clean my soul, mind, self, everything, and I found that this method it's really great, for advance listening for 8 hours straight, keep it up.
The "Advanced" tracks go into the Delta range faster, deeper, and for a longer period than the Beginner tracks. Binaural beats affect everybody differently; some people who try "Advanced" right away report headaches and nightmares, whereas others can jump right in without any problems.
