This book is written as a guide to help you learn the "Reams' Biological Theory of Ionization". This book is used by many RBTI practitioners and students of the RBTI for years. Many state that they have read the book several times and every time that they read it they learn more and see things that they did not see before, it grows as your understanding of the RBTI grows. This book is compiled from the notes from Dr.Reams in his classes and during times that I traveled with him. A must for the library of any one interested in the alternative healing art field.
