Michael,
Call the toll free number for Silva in Laredo, TX. Get it off their web site.
Why? Well, you'll never get the books any cheaper & they will only charge you the very minimum for postage. Jose Silva was a wonderful man. While you are at it, get his autobiography & Silva Mind Control for the 90's.
I am presently doing the Silva home study course; and, it's great. It's a little on the spiritual side, but that also suits me. Jose was into values.
Silva stuff is useable stuff forever.
I am working on my anchor now. I will tell you how it goes.
