Healers and Healing

How to distinguish a true healer from charlatan? What is a healing and how does it work? Who are true healers, where do they live and how to heal? In the book, there is an exhaustive information about the most prominent healers of the past and our time, about their unique experience and effective healing techniques.
The author of this book has watched the healing practice for more than thirty years before describing the striking cases of healing of hopelessly sick people who returned to normal life contrary to the forecasts of doctors. He came to the paradoxical conclusion: the basis of a huge number of methods and techniques - from direct touch and before healing at a distance used by professionals - is one-only healing force, and it is available to everyone.
