Well, he does state he meditates for hours to create the field and then associates it with the track, so I would assume there is intent on his part.
iAwake doesn’t use the very specific detailed fields that Sapien does. Also, they don’t create fields, they record them. They have fields with brainwave patterns and healing patterns. I do tend to feel calmer and am able to relax faster and deeper on those tracks.
Besides, I merely meant to look at the research papers on the iAwake site, given how extensive they are.
