Significant advances in the psychoenergetics field will be delayed until devices and techniques are developed for monitoring nonphysical energies. One general category of useful devices is that of a conventional electromagnetic nature that responds to such energies via interaction with an intermediary living transducer—human, animal, or plant. This paper, chapter 21 of Psychic Exploration, is largely devoted to a discussion of two such devices: a high-voltage (Kirlian) photography device and an acupuncture-point monitoring device. The full volume of Psychic Exploration can be purchased as an ebook or paperback version from all major online retailers and at cosimobooks.com.
