What Japanese therapy is based on the belief that channeling spiritual energy can heal the physical body?

The chosen answer, Reiki, is correct because it is a Japanese healing practice that focuses on the notion of channeling spiritual energy, often referred to as "universal life energy," to promote physical and emotional healing. Practitioners of Reiki believe that this energy can be transferred from the practitioner to the recipient through touch or by placing the hands near the body, facilitating the body's natural ability to heal itself.

In contrast, Ayurvedic medicine is a holistic approach to health originating from India, emphasizing balance between body, mind, and spirit through lifestyle, herbal remedies, and diet. Homeopathy, on the other hand, is a system of alternative medicine based on the principle of "like cures like," utilizing highly diluted substances to stimulate the body's healing responses. Lastly, osteopathy is a form of alternative medicine that emphasizes physical manipulation of the body, particularly the bones, muscles, and connective tissues, to promote overall health and well-being. These other therapies do not center on the idea of channeling spiritual energy as Reiki does.
