By connecting to higher or finer frequencies of conscious energy which is all around us, and using loving intention or thought (which, as stated before, is also energy) to heal and cleanse, the Reiki practitioner is able to direct the energy to where it is most needed.

“Not only are highly reputable medical facilities throughout the U.S. offering patients alternative healing programs such as Reiki, those facilities are analyzing the benefits of their programs and are submitting them for review and compilation. The results of these Reiki research studies are nothing short of remarkable.”

Reiki has been featured in mainstream publications like Vanity Fair, Cosmopolitan, and Elle. Christina Aguilera said that “Reiki puts her mind in a good place and also gives her the discipline to eat healthy and maintain weight loss.” Elle: “After Gwyneth Paltrow and Chris Martin’s “conscious uncoupling” heard round the Internet, Paltrow was photographed leaving a Reiki session. The goal of this practice is to reach a joyful state of mind, and like Paltrow, many women who are emotionally struggling are gravitating toward Reiki instead of, or in addition to traditional therapy.”

Richard C. Henry, Professor of Physics and Astronomy at Johns Hopkins University: “A fundamental conclusion of the new physics also acknowledges that the observer creates the reality. As observers, we are personally involved with the creation of our own reality. Physicists are being forced to admit that the universe is a “mental” construction.”

Pioneering physicist Sir James Jeans wrote: “The stream of knowledge is heading toward a non-mechanical reality; the universe begins to look more like a great thought than like a great machine. Mind no longer appears to be an accidental intruder into the realm of matter, we ought rather hail it as the creator and governor of the realm of matter. Get over it, and accept the inarguable conclusion. The universe is immaterial—mental and spiritual.”

“Reiki can be used on anyone, regardless of the person’s age or medical condition, and it carries no risk. At Portsmouth Regional Hospital, Reiki was first offered to pre-operative patients, “but it’s now all over the hospital,” Drexler says, from behavioral health to maternity, oncology, the emergency room and the ICU. “Our practitioners will work with anybody,” she says, even positioning themselves alongside equipment in the mammography department so that they can administer Reiki to women who are undergoing a biopsy. Reiki can be performed on patients who aren’t even awake, and can also benefit visitors of patients, who, knowingly or not, affect the patient’s emotional state, Drexler says.”

“After the tremendous success of this program, the formal Integrative Medicine Program under the direction of Dr. Molly Punzo, M.D. was developed in 2000 incorporating Reiki Pilot Programs (as well as Massage, Guided Imagery, Acupuncture, and Art for Healing) on the Cardiology, Orthopedic, Oncology, and Palliative Care units, as well as in the outpatient Cancer Center. During the pilot phase, outcome measurements were obtained from patients rating their anxiety and pain pre and post Reiki sessions. After analysis by the Quality Management Department, the results not only showed a decrease in anxiety and pain, but a statistically significant decrease regardless of specialty area.”
