Finally, between age twelve and eighteen, the unique blending of feeling and knowledge takes place, by means of the starting mechanism (spirit) and accompanied by its own, new hormonal emotions. This amalgamation into a totality of mind, soul, and spirit in the unique individual is known as puberty.

This book focuses on emotion (the soul), because when illness or other crises such as war occur, the human being will always return to the first certainties of his life. We think of it as a type of regression. When you are really tired, you regress/revert to the first securities of life, and that is feeling. An ill patient is therefore, by definition, more in touch with his emotions and has a higher sensitivity than the healthy person.

By virtue of this natural process a person will always start with his feelings when faced with critical changes in his life (illness or war), but also when faced with less threatening changes.  When we buy a house for example, we first want it on the basis of our emotion (the soul stage). Then we consider the financial implications (knowledge, the mind stage).  After we have bought the house, we decorate or renovate it (the spirit stage). Only then has the house become our house. Other examples of changes in life are marriage, divorce, the birth of a child, a change of job, retirement, and so on.

It will be clear how important it is that we have a good emotional development and that we are emotionally secure, in order for us to be able to make the right choices in life. This holds true also in case of illness.

The intention of this book is to make the reader move again emotionally or, if circumstances have limited the emotional development, to retrieve this stage and to make it strong enough to be used as the prevention or cure of illness. It may also serve as the prevention or cure of unhappiness and fear.

To possess the knowledge contained in this book is of less importance than to feel what it says, unless it must serve as an aid in healing others.
