Psionic Power by Charles W. Cosimano is a provocative exploration of psionics, a field that combines psychic abilities with technology. Written in 1987 and updated in 2004, the book delves into advanced techniques for creating and using devices like radionic boxes and pendulums. Cosimano, known for his controversial views, challenges traditional new age and wiccan philosophies, advocating for the use of psionics to gain personal power and freedom. The book also addresses the ethical considerations and research methods in the field, making it a comprehensive guide for those interested in device-assisted psychic activities.
