And to add on a bit regarding other courses being marketed and Holosync being called "The End".

I think that "The End" is a fitting name for Holosync when it comes to meditation pracise.
At this point in time, it is not possible for anyone to go to a deeper meditative state
than what is offered by Holosync. It is possible to slant ones attention in deep meditation to get different results but this is not the meditative state only application of the mind.

Holosync meditation is not educational and makes no such claims that any knowledge will be conveyed.

I think that Bill recommends courses that he feels would enhance your life experience. He has stated most of the time that he receives no monetary compensation for recommending these courses. These are courses that he has done and found benefit in, take it or leave it.

I'm waiting for the telepathy course, I could use it alot more than voice lessens.
