The author introduces some basic concepts and symbols of the “Secret Doctrine” - the unique work of our great compatriot Helena Petrovna Blavatsky, Messenger of the Great Himalayan Teachers. This book, which is a synthesis of science, philosophy and religion, contains Revelations of the Shambhala Scientists about the origin and development of the Cosmos, the Earth and humanity. The publication is intended for a wide range of readers, primarily for young people interested in the laws of life not only of the visible (physical) world, but and the invisible (superphysical), which, as the “Secret Doctrine” claims, constitutes the majority of the Cosmos.
