This book is outstanding from both a scientific and spiritual perspective. It is the unique record of the pioneering experiments which presents clear, electro-physiological evidence of the existence of the network of chakras and nadis which form the infra-structure of the subtle energies existing in the pranic and psychic dimensions, which underlie and activate the physical, material body of man. The book’s experiments successfully combine the objective and subjective dimensions of knowledge and will serve as blueprints and guideposts for future experiments. Charles W. Leadbeater, a clairvoyant, was a major contributor to the Western world’s understanding of the chakras and other parts of the human energy fields. This fascinating exploration of subtle body includes his pioneering work, as well as that of other respected seers.
