This is a wonderful package - a 3 volume set - covering "Dianetics, The Modern Science of Mental Health". It unfolds like a most unusual adventure.You might find it a fun thing to do on the road. It certainly keeps the kids off of their video games and completely engaged for miles and miles.If you run into anything you don't quite understand, just stop the play and consult the glossary. Easy!It is a lot of very interesting and thought-provoking information. I highly recommend this audio version.Try it yourself!
