In the evening you’re heading home alone. You will sleep alone at night. Sometimes you open your eyes, drowsy, your mind still plunged into a dream. It is there. 
Emptiness.
In your lifetime you have felt it already many times.
How can this void, by definition the absence of everything, be transformed into a feeling?
You have to know that your shadow is a friend, the only one that is a constant; it accompanies your empty body and never abandons you.

This book is a research into identity, which is based on duality, on the need to project on to someone else in order to define oneself.
