though the preset is 20 minutes long, it will continue after that time is up. 20 min minimum, longer if you are having trouble slowing down...but don't keep track of time.

Have you ever used binaural beat technology before? It's quite amazing. The first time I used this preset, I literally felt thoughts being RIPPED out my skull. I was trying to think normally with an inner voice and the voice had the sound of a mentally handicapped person or... like a warped, stretched audio tape. It wouldn't let me think. Whenever I created a vocal thought, it would tear it to shreds. And when I arose after 30 or so minutes, I felt and saw as a Zen Master would feel and see... Anna Wise's Awakened Mind profile...the real deal. It was quite trippy actually, though short lasting.
