The book is dedicated to the origins of the worldview of the Russian people that developed in the pagan era. One of its most striking manifestations is the "Pigeon Book" - a sacred legend of our distant ancestors, in which they expressed their idea of ​ ​ the origin of the universe and man. The core of this oldest work of Russian spiritual culture took shape at least 5,000 years ago. For the first time in Russian historiography, the idea of ​ ​ the Slavs about the universal law, which developed in the era of the Indo-European community, is being investigated.
