Charles W. Leadbeater, influential member of the Theosophical Society and a trained clairvoyant, reveals here in considerable detail the features of the astral plane, the types of entities that inhibit it and other fascinating and useful information. The little work records an attempt to describe the invisible world approached from the standpoint of science in the same manner a botanist would map out a new territory on this globe.
