'Clairvoyance' is a fascinating book by Charles W. Leadbeater, a Theosophical and occult author, originally published in London in 1899. The book provides an in-depth study of the belief in seeing beyond ordinary sight and describes a wide range of phenomena that can be experienced through the practice of clairvoyance. Leadbeater claims that clairvoyance is an extension of common perception and is accessible to anyone. The book is divided into nine chapters, covering topics such as what clairvoyance is, methods of development, and the different types of clairvoyance, including simple and intentional clairvoyance in space and time.
