The Book of Runes presents theoretical research in the field of the Runic System and practice based on this research, and this practice has been tested for years. First of all, this is a detailed description of the Runic System itself and its practical application to humans - runic diagnosis and correction. As a result of diagnostics, a variety of problems that a person may have are revealed, and as a result of correction, a person gets rid of these problems. And all this is done not on the basis of exclusively magical methods, but on the basis of a purely scientific approach.
