The main result of this book is the discovery of the fundamental fact that the biographies of Krishna and Buddha basically reproduce the biography of Emperor Andronicus-Christ (aka Horde prince Andrei Bogolyubsky). In fact, Krishna is the Eastern image of Andronicus-Christ, and in The biography of Buddha contains a significant layer that relates not to Buddha himself - the Indian prince Sakya-Muni, also known as the Christian saint Joseph, prince of Great India - but to Andronicus-Christ from the 12th century. Some parallels between Krishna and Christ, as well as between Buddha and Christ, have been noted by various scientists earlier. However, these observations were scattered and random. The authors managed, apparently for the first time, to reveal the full picture of this striking correspondence. It has far-reaching consequences and changes a lot in our ideas about the history of the East. The book presents new results obtained most recently. The reader does not require any special knowledge. All you need is an interest in general and Russian history and a desire to understand its many mysteries. The book is intended for a wide range of readers interested in the application of natural scientific methods in history.
