Awakening Prologue is the introductory level. If you like it then you will be sent information about buying the whole program (inner circle). I didn't buy the whole level.
Instead I wait until the soundtracks go on sale(twice a year they go on sale) and then I order my next level.
Personally, (if interested) I would try out Awakening Prologue for 4 months and if it's something that you like then I would consider buying the next level. If not I would send it back (1 year money back guarantee). A small fraction of people report that they don't see any results. Not me mind you I am in the opposite extreme (the growth is amazingly rapid) but if I was one of those people I wouldn't hesitate about sending the program back.
One last thing I wouldn't go into this thing unless you are really serious about your personal growth. There is a reason that people repress and hold onto limitations and that's because it can be painful to deal with them. If you are not prepared to breakthrough your fears and limitations then I wouldn't recommend this program. Its relentless and it won't let you off the hook (what I mean is that with other programs I have done if the process got a little involved or I didn't want to deal with something then I would just put it off). Not so with holosync as long as you keep listening you will keep growing at a rapid level.
