The book, from the standpoint of theosophy, tells about the origin and evolution of the solar system, its planets, life on them, earthly humanity, its great civilizations, as well as their individual representatives. In addition to adventures in the theosophical worlds of the past, the reader is offered a detailed description of the beautiful theosophical world of the future, the advent of which is expected in the 28th century. The use of clairvoyance to study the past is no longer new: H. P. Blavatsky's The Secret Doctrine is a prime example of this. Can the results of studies conducted in this way be trusted? This is a question that should be left to future generations, when they will already fully own the power used by the authors.
