This work explores the prehistoric civilizations of Atlantis and Lemuria through theosophical clairvoyant investigation, matching esoteric records with geological and biological evidence. The text details the descent of humanity through successive root races, charting the physical and spiritual evolution of early mankind across various geological epochs.
The narrative opens with an explanation of the method of research, describing how advanced adepts access the imperishable memory of nature to retrieve forgotten history. The physical configuration of the earth during successive periods is mapped out, demonstrating how ancient land bridges and continents once connected regions now separated by vast oceans.
The history of the Fourth Root Race on Atlantis is traced across its four main sub-races and subsequent cataclysms. The text details the zenith of the Toltec empire, examining its advanced architecture, water distribution systems, aerial navigation, and the social and agricultural systems that sustained millions of inhabitants.
As the Atlantean civilization progressed, moral decay and the abuse of psychic powers led to the practice of sorcery. This turning away from spiritual guidance brought about catastrophic destructions, culminating in the sinking of the continent and the final submergence of the island of Poseidonis.
The second portion of the text investigates the earlier Lemurian continent, detailing the physical characteristics, size, and physiological evolution of early human forms. The work examines the gradual physical hardening of the race and the historical development of reproduction, language, and early social structures.
The volume concludes by connecting the remnants of these ancient races with modern populations and outlining the cyclic progression of human evolution. The emergence of the Fifth Root Race from early Atlantean stocks is framed as part of a continuous spiritual ascent toward higher consciousness.
