Well, if you look at it from a larger perspective, everything is energy. but on a smaller level your mind is plugged into your brain from a higher dimension. Your mind is the first cause that everything originates from. Now this is not to say that the brain cannot affect the mind indirectly but the mind is always in control even if you decide not to exercise that control.
When you take in new knowledge/experience it adds fibers to your energy bodies (assuming you have more than one). These fibers cause a shift in your physiology and create new neural pathways in your brain to allow you to better handle or intepret the fullness of the information contained within your energy being.
As an example, let's say you visit a park. There are millions of things going on in every instant but your brain may only be picking up on a fraction of the total experience. Now this is speaking subconsciously. Consciously, however you get an even smaller portion of the experince that your subconscious recorded.
So there is definately a change needed in the brain but that comes only as result of a change in the energy being.
I think holosync is very limited in its approach. While it may (perhaps?) build neural pathways (to what extent?) it does not however give you control of any kind over that new machinery you have built. Think of it like taking LSD. It may push you into having spiritual experiences but since you are not the one in control, if you ever lose access to the drug you will not be able to go back. The same holds true of Holosync. if you acheive something interesting and you lose the ability to listen to your CD's then you are left stranded with out your crutches.
A second issue I have with holosync is the stated purpose according to Bill Harris is not the experiences but to feel better or make your brain work better, or other mundane physical trivalities. I feel he has it backwards. He is more interested in the car than he is in the trip.
Third is the price. I think they string you along and drag out the course much more than is necessary. I think the guy is too money oriented. Anyone who has done any business with them knows hwo they get flooded with direct marketing from tons of other people that he gives your information to.
