Louis Yagera has an interesting blog, writing mostly about his experiences with audio CD’s that enable mediation, altered states etc. He has now posted a list called A-Z of Mind Expansion where he explains various terms and links to sources of mind expansion technologies on the net. I was also pleasantly surprised that he included my site on his list. Thank you, Louis.
So ,if you want to learn more about the various brainwave patterns and who creates the CDs, visit his site.
