Light Changes: Experiences in the Presence of Transforming Light

Light and experiences of light have fascinated humanity since the earliest of times. Annekatrin Puhle traces this fascination, taking a scholarly view of these experiences, raising exploratory questions where necessary and, as a good scientist, questioning, answering, and classifying the data that she puts before us. The data in the book is gathered from numerous sources, going right back in history, through that great period in the 19th century when surveys of apparitions and light phenomena were the focus of much public attention and scientific interest, to the present day and the presence of light in modern digital photographs, where a distinction has to be made between dust phenomena and what are true spiritual energies .
