It is an outstanding book from both the scientific and spiritual points of view. 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 experiments in the book successfully integrate the subjective and objective dimensions of knowledge, and will serve as guideposts and blueprints for experiments in the years ahead. The chakras and other components of the human energy field were largely brought to the attention of the Western world by clairvoyant Charles W. Lead beater. His pioneering work is discussed in detail in this fascinating exploration of the subtle body, along with that of other respected seers and yogis.
