This book is devoted to areas most people have never thought about or perhaps do not even know they exist. My primary goal is to provide information which will enable to learn the true human nature by realising the actual state of this world, in its material dimension, is the light and waves. I acquired that knowledge summing up my personal experience, encounters with people having supernatural powers, and forty-year scientific research, enriched with invaluable messages from a higher dimension which I also refer to in my work. The said knowledge: 1. Will enable us to understand the notion of consciousness anew, how to handle, and control it. 2. Thanks to it, we will redefine our ego. 3. It will show us the true human nature. 4. It will help us cross the boundary of a material world and, all the same, comprehend the existence of a nonmaterial dimension and a multidimensional world.
