I have already read some books in order to understand a little more what is so inexplicable. This book is revolutionary! It carries the formula, the secret, after mankind has been looking for so long. Dr. Sha and Dr. Rulin explain in a clear and comprehensible way the relationship between soul, heart, mind and body - scientifically sound and yet well understood. The practical exercises allow the immediate application of the knowledge and offer the candid reader an invaluable treasure for daily life in book form. Absolutely fascinating! We recommend !!!
