After abandoning Kriya yoga, Salinger tried Dianetics, even meeting its founder L. Ron Hubbard. This was followed by adherence to a number of spiritual, medical, and nutritional belief systems including Christian Science, homeopathy, acupuncture, macrobiotics, the teachings of Edgar Cayce, fasting, vomiting to remove impurities, megadoses of Vitamin C, urine therapy, "speaking in tongues", and sitting in a Reichian "orgone box" to accumulate "orgone energy".
