This book has three essential parts. In the first part, Dr. Cowan discusses how the idea that the heart is a pump cannot possibly describe how circulation occurs. In the second part, he reviews how the heart is the energy centerr of the body and directs the activity of the whole. It is no mistake that we hold things to our hearts. Finally, we discuss that a healthy life begins with healthy food from healthy soil and our water needs to have the natural energy as it usually springs from the earth. An anagram for heart!
