I've had a sound CD set from a guy called Beau Miles and I've had it a year or so and it is superb...
I can however state that opening up and not closing down properly is very un-nerving if not done...

There is a good lecture audio on here too...
A YouTube intro:

I bought this CD and was waiting for it for 7-8 days and it arrived about an hour before I was due to go out into London. I did not listen to CD1 the manual and jumped straight into listening to what I'd just bought!!! Impatience etc
Anyway I went to someones house for ~1 house to listen to some hifi (i'm a hifi/music nerd

) and then went off to meet someone in London on the tube.
Fortunately this person was spirtual and knew what to do... Well anyway I can over all weird and I'm fit and well. I felt queasy and needed to get out of the tube asap... bad energy etc or negative etc. I held a crystal and listened to her MP3 until the next stop and we got off but I was in a very strange place I'd never been before or since! I'm almost 100% convinced it was due to me opening up and not closing down properly...
Anyway I thought I'd just share this story with you all on not doing things in a safe and structured manner.
Anyway I can recommend the CD's above and I did them fully regularly every 3-4 days (as well as the daily tracks) for months and it helps to have a very good stereo which almost sounds real... Some benefits from being a Hifi nerd
ps if you get the CDs listen to CD1 fully first

or learn a lesson like I did
