"Sound Quality"
This was made to be listened to with headphones to get the full effect and the sound quality is terrible. It really may not do anything for you. I love Audible but this one needs some special attention from them to make it useful to you. Your best bet is to buy the cds elsewhere, as in their proper condition you will be quite pleased!
"Self-Realization"
This is an absolutely fascinating book! You get an honest look into the life of an amazing being. You also (if you don't know) get to learn what it means to be a yogi and what a yogi is. This book could be a stepping stone for a great many people who are ready for something nearly everyone really wants... Self-Realization! No question, this book is for YOU.
